I am working on Debian Stable Linux. I installed luafilesystem module by command:
luarocks --local install luafilesystem
However, it is not found when any of following is used in lua source files:
require ("lfs")
require ("luafilesystem")
(Although these files run properly when ran from within ZeroBraneStudio IDE).
From a suggestion on the web, I ran following command also:
luarocks --local install luarocks
But it does not help. I checked with luarocks-admin command, which showed:
CONFIGURATION
Lua version: 5.1
Configuration files:
System: /etc/luarocks/config.lua (ok)
User : /home/abcd/.luarocks/config-5.1.lua (not found)
Rocks trees in use:
/home/abcd/.luarocks
/usr/local
Currently, I only have these 2 modules installed:
$ luarocks list
Installed rocks:
----------------
luafilesystem
1.7.0-2 (installed) - /home/abcd/.luarocks/lib/luarocks/rocks
luarocks
2.4.3-1 (installed) - /home/abcd/.luarocks/lib/luarocks/rocks
Should I copy /etc/luarocks/config.lua to /home/abcd/.luarocks for this? Thanks for your help.
The LUA_PATH and LUA_CPATH environment variables control the paths searched by lua when looking for packages. These are probably not set correctly. Include the paths used by luarocks in these variables by running
eval "$(luarocks path)"
and you should be all set.

I have installed Qt 5.1.4 but when I 'make install' it shows
Package Qt5Gui was not found in the pkg-config search path.
Perhaps you should add the directory containing `Qt5Gui.pc'
to the PKG_CONFIG_PATH environment variable
No package 'Qt5Gui' found
Package Qt5Widgets was not found in the pkg-config search path.
Perhaps you should add the directory containing `Qt5Widgets.pc'
to the PKG_CONFIG_PATH environment variable
No package 'Qt5Widgets' found
Package Qt5Multimedia was not found in the pkg-config search path.
Perhaps you should add the directory containing `Qt5Multimedia.pc'
to the PKG_CONFIG_PATH environment variable
No package 'Qt5Multimedia' found
But I installed this software qt-opensource-linux-x64-5.14.0.run, after I tried to find them I ran locate Qt5Gui but no Qt5Gui.pc returned,so how can i get Qt5*.pc on my ubuntu 20.04 ?
The installation I started was missing a few more packages
The complete installation should look like this
sudo apt install qtmultimedia5-dev qt5-default -y
The construction of the qt compilation environment requires more than the installation package downloaded from the official website
It worked for me !
Now i can find the Qt5*.pc !
You need to install qtbase5-dev which is part of qt5-default
see: https://packages.ubuntu.com/bionic/amd64/qtbase5-dev/filelist
EDIT: you may also have to install the package qtmultimedia5-dev.
I'm trying to install omnetpp 5.2.1 on windows 10. But getting an error while doing ./configure command related to QT environment. I tried changing the configure.user file in omnetpp package to change the path of QT but still its not working. Here is the error:
configure:error: Qtenv cannot find qmake--maybe it is not in the path
or has some exotic name (tested names were: qmake qmake-qt5 qmake5)-
disabling Qtenv. You can try setting QT_PATH variable in
configure.user to a valid location.
qt5 might not be installed.
sudo apt install qt5-default worked for me while installing on Ubuntu 20.04.
OMNeT++ comes with all dependencies bundled. As long as you have executed the mingwenv.cmd and running from that shell, qmake should be available in the path (in tools/win64/mingw64/bin). Check if qmake.exe is present there. If not, make sure that ZIP file you have downloaded is intact. Standard windows unzip may fail on certain systems...
run ./configure WITH_QTENV = no
I tried to install mcsema on my debian linux but I am stopped by error
Cmake 3.1 or higher is required. You are running 3.0.2. On debian this is the only version could be installed by apt-get install. Building CMake from sources, I get several errors as well. Does anyone know how to install the latest version of Cmake on Debian 8?
Download latests cmake release and follow the README.rst instructions:
UNIX/Mac OSX/MinGW/MSYS/Cygwin ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
You need to have a compiler and a make installed. Run the
bootstrap script you find in the source directory of CMake. You
can use the --help option to see the supported options. You may
use the --prefix=<install_prefix> option to specify a custom
installation directory for CMake. You can run the bootstrap script
from within the CMake source directory or any other build directory of
your choice. Once this has finished successfully, run make and
make install. In summary::
$ ./bootstrap && make && make install
I've installed CMake 2.8.11.2 package from CMake's website for Mac 64-bit. We recently upgraded a project from Qt 4 to Qt 5 and the CMake upgrade is mandatory for CMake to use Qt 5. However, when I type cmake . I get the following error:
CMake Error: Could not find CMAKE_ROOT !!!
CMake has most likely not been installed correctly.
Modules directory not found in
/Applications/CMake 2.8-11.app/Contents/bin
CMake Error: Error executing cmake::LoadCache(). Aborting.
I can confirm, there is no modules directory in the bin folder. I really don't know how to resolve this error, or how to get the modules needed.
Do hash -r to clear the cache, then do cmake --version.
It should work.
I had the same problem after upgrading on Ubuntu.
Removing cmake and the cmake-data package before performing the update solved it for me.
sudo apt-get remove cmake cmake-data
Now perform the update via
sudo -E add-apt-repository -y ppa:george-edison55/cmake-3.x
sudo -E apt-get update
sudo apt-get install cmake
This worked for me :
cd cmake-3.4.3
./bootstrap --prefix=/usr
make
sudo make install
Additionally, you may encounter the same error when running CMake from Cygwin. This may be caused by a PATH variable listing /bin before /usr/bin: in this case CMake is launched as /bin/cmake instead of /usr/bin/cmake, and trying to load modules from //share/cmake-X.Y.Z (which is a UNC path on Windows) instead of /usr/share/cmake-X.Y.Z.
Explicitly export'ing a correct CMAKE_ROOT isn't helpful, and cmake keeps displaying the same misleading message.
The issue can be solved by setting PATH to /usr/bin:/bin:/everything/else in your .bash_profile.
I was able to fix this error on Linux (for other who may be searching for answer on Linux) while trying to upgrade cmake 2.8.11 to 2.8.12 by exporting the CMAKE_ROOT environment variable like so:
export CMAKE_ROOT=/path_to_install/cmake-2.8.12.2-Linux-i386/share/cmake-2.8
The share directory should be on the same level as your bin directory.
I got the same error message upgrading cmake-3.5.1 to cmake-3.7.1 on Ubuntu 16.04.01 LTS. I just updated the repositories with
sudo apt-get update
Then
cmake --version
brought up the correct and upgraded cmake version and the error messages was gone.
In my opinion/case this is a developer "problem". I suspect this occurs mostly to new developers so I go a bit deeper to put it in the right perspective:
To "not mess with" the original system files used for daily work and separate the new compiled and volatile programs in a separate location it is common to not just change but add/mount a complete folder structure similar to the original OS folder structure in a special "development" location.
So more or less a mirrored folder structure of the original one but connected/linked to the original resources.
There for we need to add an environment variable to our user bash profile where we tell the system: "link our development folders to the following direction/dir."
On Arch Linux this is done in a file in ~/.bashrc - that is linked/forwarded in/by the ~/.bash_profile ("~" stands for /home/your user name/) and MacOS/Unix will be similar.
To do that there are 2 ways:
you can open the .bashrc file and add your environment path to the bottom of it
or
you can use "export" to put the environment variables to the right place in your user bash file.
for kde development e.g. you need to add a path at the end of the ~/.bashrc file like so:
# Adding the kdesrc-build directory to the path
export PATH="$HOME/kde/src/kdesrc-build:$PATH"
what basically tells the system: the development is done in the /home/user name/kde/src folder - there are your files. You can choose where you want to locate your development environment.
If you execute cmake it "thinks" your files are in the original OS folder and the "Could not find CMAKE_ROOT" - message will disappear because it finds all your files since properly linked from your development folder structure to your system folder structure.
So basically to solve the problem you could just execute cmake in the right system folder - it just could mess up your system if the program or make files are not proper done so it is pulled to the home folder development folder structure. And you just have to tell that cmake, so it can find all needed files to compile your stuff, including the CMAKE_ROOT.
Another problem could be that cmake isn't properly installed.
On Arch Linux systems that can be made sure by using the "sudo pacman -Syu cmake" command and it copies the files in the right direction and sets the right user variables to get it executed and reinstall cmake if necessary.
Btw, if you are on other systems like Debian make sure to use a Debian apt repository, it can differ from the Ubuntu repository, especially if you compile for the chosen system.
I tried to write a general "beginners in mind" overview to get em a fundamental picture. Executing cmake in the right folder solved that exact problem for me that was asked for.
(Actual that flags works for the actual cmake version from the official arch repository:
1:
cd /home/ivanovic/kde/src/program_name
than:
2:
cmake -S/home/ivanovic/kde/src/program_name -B/home/ivanovic/kde/build/program_name -DCMAKE_INSTALL_PREFIX=/home/ivanovic/kde/usr -DCMAKE_BUILD_TYPE=Debug
Pay attention that between -S and /home/... is no space, same at -B and /home/...
This worked fine for my kde system software builds.
)
If anyone gets the following error:
Modules directory not found in
/usr/share/cmake-3.20
cmake version 3.20.2
Solution which worked for me:
sudo cp -r /share/cmake-3.20 /usr/share/
The above command copies the cmake-3.20 directory from /share to /usr/share
This also happened to me on a fresh install of Ubuntu 21.04 and was fixed by installing it from "snap":
sudo snap install cmake --classic
(and then making sure that /snap/bin is in $PATH)
tl;dr: check the permission of folder /usr/local/share/cmake-x.xx.
I had a similar problem with the cmake that I build from source code. I compile the code with the following command.
./configure
make
sudo make install
and the binary files were placed into /usr/local/bin as expected. But I will encounter the same problem when executing cmake without sudo privilege. This is because the normal user don't have reading permission with folder /usr/local/share/cmake-3.xx.
The error went away when I give myself the permission to read/execute, with the command.
sudo chmod 755 /usr/local/share/cmake-3.xx
(xx will be the specific version that you installed.)
I am a novice with zeroMQ and I am stuck at binding ØMQ with java on a server running CentOS release 5.9.
Unfortunately, I do not have super user/root privileges on the server and am trying to install ØMQ as a normal user with restricted privileges. I have installed ØMQ by following instructions on http://www.zeromq.org/area:download
Make sure that libtool, autoconf, automake are installed.
Check whether uuid-dev package, uuid/e2fsprogs RPM or equivalent on your system is installed.
Unpack the .tar.gz source archive.
Run ./configure, followed by make.
Could not run the following obviously
To install ØMQ system-wide run sudo make install.
On Linux, run sudo ldconfig after installing ØMQ.
Then I attempted to install jzmq.
Cloned [git clone https://github.com/zeromq/jzmq.git]
Ran autogen.sh
Ran configure
At this point I get the following error
checking for ZeroMQ... no
checking zmq.h usability... no
checking zmq.h presence... no
checking for zmq.h... no
configure: error: cannot find zmq.h
As a result of the above error I am not able to run java tests and get error "no jzmq in java.library.path".
Can anybody help/direct me to how to get java binding for zeromq work when you dont have root privileges to install it? Its difficult to get IT department to install a new software on servers.
Appreciate your help.
Note: I do not have write permissions to /usr directory
Thanks
GBP
This can be overcome by adding --with-zeromq=/home/user/zeromq (installation directory of zeromq)
./configure --with-zeromq=/home/user/zeromq
Other steps include
export LD_LIBRARY_PATH=/home/user/zeromq/lib
You can also use JeroMQ (https://github.com/zeromq/jeromq) which is a pure Java implementation of ZeroMQ
I got this working by running autogen.sh on OEL 6 then running configure / compiling / installing on CentOS 5.9. I briefly looked into why autogen.sh was failing and the problem was the tool chain was too old. Since I had a more up-to-date system with a modern tool chain available running autogen.sh on something other than CentOS 5 was the easiest path for me. I'm sure it works fine with other modern Linux variants, I had OEL 6 at my finger tips.
I also did not have access to a standard directory for installation. To get that working I added zmq.jar to my class path, and the run-time linker needed to be able to find the zeromq and jzmq run-time libraries.
I faced the same issue on CentOS 6.5 and found that you need to install "gcc-c++" for this to work.
I used the following to install dependencies:
yum -y install jdk zeromq-devel unzip libtool gcc autoconf automake gcc-c++ python
Note that "jdk" comes from our private repository and it's same what can be downloaded from java.com
The following public repositories are installed on server:
atomic
Actually, I ended up having this same issue, and the following script worked for me, where I installed zeromq into ~ (so that I have ~/lib contains libzmq.a libzmq.la libzmq.so libzmq.so.3 libzmq.so.3.1.0 pkgconfig)
./autogen.sh ./configure --prefix=$HOME \ #because you don't have root privileges
--with-zeromq=$HOME --includedir=$HOME/include/ --libdir=$HOME/lib/
./make
./make -n install
#to check to see if it installs it to the right location
make install
