I'm trying to run "Triangulation_3" examples and while doing the "cmake" I get this error:
CMake Error at CMakeLists.txt:44 (include):
include could not find load file:
CGAL_TBB_support
I'm using ubuntu 20.04 and I've already installed TBB library using
sudo apt-get install libtbb-dev
How can I fix this error?
Thanks.
It seems you are using the system libcgal-dev version 5.0.3, as provided by apt for Ubuntu 20.04. That version of CGAL does not have the CMake module CGAL_TBB_support.cmake.
Probably you are using CGAL examples from more recent version of CGAL, maybe one you downloaded or cloned using Git.
If you recent version of CGAL is, for example, at the path /home/me/downloads/CGAL-5.3, then set the CMake cache variable CGAL_DIR to that directory. You can pass the option -DCGAL_DIR=/home/me/downloads/CGAL-5.3 to the cmake command line, for example. Or set the variable CGAL_DIR to /home/me/downloads/CGAL-5.3 in CMake-GUI. Of course, adjust you the real path on your system.

I try build this khancyr/ardupilot_gazebo (github) plugin but I get this error after run sudo cmake ..
I use fedora35 so I cant run apt-get install libgazeboX-dev
what can I do for this problem ?
CMake Error at CMakeLists.txt:11 (find_package):
By not providing "Findgazebo.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "gazebo", but
CMake did not find one.
Could not find a package configuration file provided by "gazebo" with any
of the following names:
gazeboConfig.cmake
gazebo-config.cmake
Add the installation prefix of "gazebo" to CMAKE_PREFIX_PATH or set
"gazebo_DIR" to a directory containing one of the above files. If "gazebo"
provides a separate development package or SDK, be sure it has been
installed.
Have you tried running apt-get update && apt-get install ros-foxy-gazebo-ros-pkgs before running your command.
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 installed PCL using the following commands.
sudo add-apt-repository ppa:v-launchpad-jochen-sprickerhof-de/pcl
sudo apt-get update
sudo apt-get install libpcl-all
When I compiled my PCL program with the following lines in CMakeLists.txt
find_package(PCL 1.3 REQUIRED COMPONENTS)
include_directories(${PCL_INCLUDE_DIRS})
link_directories(${PCL_LIBRARY_DIRS})
add_definitions(${PCL_DEFINITIONS})
I have errors as
CMake Error at CMakeLists.txt:17 (find_package):

I can't locate PCLConfig.cmake and pcl-config.cmake in my system.
I did like
locate PCLConfig.cmake

/home/ttt/.local/share/Trash/info/PCLConfig.cmake.trashinfo
/home/ttt/Softwares/voxelsdk/config/VoxelPCLConfig.cmake.in
/usr/lib/cmake/VoxelPCL/VoxelPCLConfig.cmake
Does it make sense?
I tried like
set(PCL_DIR "/home/ttt/.local/share/Trash/files/PCLConfig.cmake")
find_package(PCL 1.3 REQUIRED COMPONENTS)
include_directories(${PCL_INCLUDE_DIRS})
link_directories(${PCL_LIBRARY_DIRS})
add_definitions(${PCL_DEFINITIONS})
But still have the same error.
How to locate PCLConfig.cmake in my system?
Thanks
you should specify the PCL dir for the CMake to find it.
In a terminal run :
$ locate PCLConfig.cmake
Then, add the found folder (without the filename) to your CMakeLists like the following :
set(PCL_DIR "/found/folder/")
#change X.x to whatever version yo installed
Sidenote : /usr/share/pcl-x.x is the usual path to your pcl folder.
I had the same problem when I followed the steps mentioned on the website http://www.pointclouds.org/downloads/linux.html, for Ubuntu 18.
You simply need to run
sudo apt install libpcl-dev
as bionic is not mentioned in the distributions (http://ppa.launchpad.net/v-launchpad-jochen-sprickerhof-de/pcl/ubuntu/dists/)
I am using Point cloud library 1.5.1. When I run CMake 3.4.0-rc2 to build my project, it has error:
Could NOT find PkgConfig (missing: PKG_CONFIG_EXECUTABLE)
How do I fix this error?
This error is raised because the pkg-config utility is not available on your system.
Using PkgConfig with CMake is not a truly cross-platform solution, as Windows does not come with the pkg-config utility installed. (The PCL developers should instead use find_package() in their CMake. Perhaps, this is worth opening up a bug report on their Github.) On Linux, this is an easy fix; you can install pkg-config like this:
sudo apt-get install pkg-config
However, on Windows, the process is more involved. There are several solutions for installing pkg-config on Windows documented here. I'm not sure which most directly applies to your situation, so I suggest reading through some of those. After successfully installing the pkg-config utility on your Windows machine, clear your CMake cache, and re-run CMake. This should remove the error, and allow your build to proceed.
Install vcpkg: https://vcpkg.io/en/getting-started.html
Install pkgconf:
.\vcpkg install pkgconf
If use CMake, delete the Cache files/folders: CMakeCache.txt and CMakeFiles. After that, run the command
cmake .. -DCMAKE_TOOLCHAIN_FILE=C:\dev\vcpkg\scripts\buildsystems\vcpkg.cmake
On Fedora 34, it was because of multiple pkg-config
/home/sapillai/go/bin/pkg-config
/home/sapillai/go/bin/pkg-config
/usr/bin/pkg-config
/home/sapillai/go/bin/pkg-config
I deleted the others and kept /usr/bin/pkg-config. Error was gone.

./configure results in:
configure: error: Package requirements (mono >= 2.4.3) were not met:
No package 'mono' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables MONO_MODULE_CFLAGS
and MONO_MODULE_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
which mono
/bin/mono
echo $PKG_CONFIG_PATH
/usr/local/lib/pkgconfig
but if I check for pkgconfig,
which pkgconfig
/usr/bin/which: no pkgconfig in (/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin)
yum provides pkgconfig
1:pkgconfig-0.27.1-4.el7.i686 : A tool for determining compilation options
Repo : base
yum install pkgconfig
Package 1:pkgconfig-0.27.1-4.el7.x86_64 already installed and latest version
A similar question was asked last year with no accepted answer. One of the answers pointed to a now non-existent page with a purported solution.
I believe pkg-config itself is working all right, configure is not complaining about that. What's missing is the entry for mono in the pkg-config database. Make sure you have mono.pc in /usr/local/lib/pkgconfig, or add wherever you have this file to PKG_CONFIG_PATH as instructed. On some linux distributions, development packages need to be separately installed, such as libmono-cil-dev on debian.
