By default, compiling hla filename.hla builds an executable in the currently directory. Can a different directory be specified?
ENVIRONMENT
HLA (High Level Assembler - HLABE back end, LD linker)
Version 2.16 build 4463 (prototype)
Ubuntu 20.10
SOLUTION
This can be specified by using the option -x:name Executable output filename (does not append ".exe"). Found in the hla help, under the "Assembler and Linker Control" section.
To change the output directory consider -x:name to be -x:/path/to/name instead.
EXAMPLE
user#host:~/example$ ls
src bin
user#host:~/example$ cd src
user#host:~/example/src$ ls
filename.hla
user#host:~/example/src$ hla -x:../bin/filename.x filename.hla
user#host:~/example/src$ ls
src.hla src.o
user#host:~/example/src$ cd ../bin
user#host:~/example/bin$ ls
filename.x
user#host:~/example/bin$

Since yesterday none of my packages containing tests build. Catkin complains it cannot find gtest when using catkin_add_gtests(), since GTEST_FOUND is FALSE. You can see this in the error msg below, with the custom output I added to my CMakeLists. Up to yesterday, GTEST_FOUND was TRUE when catkin_add_gtests() was called.
This is the error I always get. In this case I'm trying to build a mockup package on a clean catkin workspace:

I am using catkin 0.7.11, libgtest-dev 1.7.0 and cmake 3.5.1. I use ROS Kinetic with Ubuntu 16.04. The only thing I did yesterday was reinstalling ROS Kinetic, but the package versions are exactly the same. Did anybody have this problem? Do you have any ideas on what could be happening?
EDIT 3/09/18:
By comparing with a functional catkin+gtest workspace in a different computer, I found out that the main difference is in the results of /opt/ros/kinetic/share/catkin/cmake/test/gtest.cmake. In the functional workspace, line 292 evaluates to TRUE (gtest/gmock is not a target) while in my workspace it evaluates to FALSE. This is because in my workspace running find_package(GMock QUIET) (line 287) sets gmock and gtest as imported targets, which does not happen in the other computer. Why is this different?
Thanks TikO for your help!
Since you wrote that cmake does not find the libraries and that you have reinstalled Kinetic, I assume that you have a freshly installed machine or wiped out gtest libraries by accident.
If you install libgtest-dev, you only get the sources which you need to build and install like this:
sudo apt-get install libgtest-dev
mkdir /tmp/gtest_build && cd /tmp/gtest_build
cmake /usr/src/gtest
make
#copy or symlink libgtest.a and ligtest_main.a to /usr/lib folder
sudo cp *.a /usr/lib
After this routine, you should be able to build again without cmake complaining.
Optional
If you have limited rights on your machine and you are not allowed to install the libraries in that way, just copy them into some home folder like
mkdir ~/lib && cp *.a ~/lib
But be aware of the fact, that you have to call catkin in the following way:
LIBRARY_PATH=~/lib GTEST_ROOT=~/lib catkin_make
LIBRARY_PATH tells the linker where to find the libraries, while GTEST_ROOT gives cmake the location hints for it's checks.
Reference: https://github.com/tik0/gtest_ros_example
SOLUTION FOUND
gmock and gtest were being set to imported target because the suggested manual compilation of libgtest had created a FindGMock.cmake file inside /usr/share/cmake-3.5/Modules. This file was being called by the find(GMock QUIET)
in catkin_add_gtests(), therefore setting the imported target. Just deleting FindGMock.cmake solved the issue.
I have built libgit2 on my Ubuntu 16.04 machine, and everything seemed fine. I ran make in the /examples directory and when I try to run ./log I get the following:
./log: error while loading shared libraries: libgit2.so.26: cannot open shared object file: No such file or directory
But, in the /build folder I indeed have both libgit2.so and libgit2.so.26 so I am not really sure what I am missing. I can post more info if it is needed. I am using cmake version 3.5.1.
The Makefile in the examples will provide guidelines for usage, which should be suitable when you have actually installed libgit2 into system library locations.
To build the examples within the source directory, you should use cmake to build the examples. Given a fresh configuration:
$ mkdir build
$ cd build
$ cmake .. -DBUILD_EXAMPLES=ON
$ cmake --build .

I'm trying to create a plugin for OBS using C, and compiling it using cmake .. && make see - https://github.com/jp9000/obs-studio/wiki/Install-Instructions#mac-osx
when running cmake .. && make from cmd it gives me an error that cmake: command not found and when I run it from the program it gives me an error - CMake Error: The source directory "/Users/gerwin/Desktop/soOBS" does not appear to contain CMakeList.text specify --help for usage, or press the help button on the cmake GUI
How can I generate a CMakeList.Text to compile my soOBS script to a .so file?
One problem is that cmake is not in your path. So, if you type cmake from your command line it cannot be found. The other problem is that you are not specifying correctly your source directory: you have to specify as source directory the location of the main/root CMakeLists.txt.
So, proceed as follow:
Locate your cmake executable, obtaining your <full path to cmake>
Open a shell
Go to your source directory (location of the main/root of obs-studio CMakeLists.txt)
mkdir build
cd build
<full path to cmake> ..The first argument .. is your source directory, location of the main CMakeLists.txt
make
Describe difference between these two command lines:
C:\xxxxx> cmake -help
Usage
$ cmake [options] <path-to-source>
$ cmake [options] <path-to-existing-build>
Specify a source directory to (re-)generate a build system for it in the
current working directory. Specify an existing build directory to
re-generate its build system.
The last description does not give me how to use the first, or the second.
Could you explain it to me?
When you use you do an in-tree build (cmake .), there is no difference.
When you do an out-of-tree build, there is a difference.
Suppose your project lives in ~/foo and your current directory is ~/foo/build
You have to run cmake .. for the first build. But for subsequent reconfigures, you can use cmake . because there is already a build there.
This command:
cmake [options] <path>
works as follows:
if <path> is not a valid (that is, already configured) CMake build directory, it is assumed to contain a CMakeList.txt. CMake will configure the current working directory as a build directory using <path>/CMakeLists.txt for source directory.
if <path> is a valid CMake build directory, the command reconfigures that directory using the source directory assigned when you first configured that build directory
So the common usage patterns are:
initial configuration:
mkdir my-build-dir
cd my-build-dir
cmake [options] my-source-dir
subsequent (re)configurations:
cmake [options] my-build-dir # current-work-dir is not important
alternative (initial) configuration using undocumented options:
cmake -Hmy-source-dir -Bmy-build-dir [options] # cwd is not important
I'm trying to add DKMS support in a kernel module i'm working on.
I have placed the kernel module source with a static lib to be linked against in the following directory:
/usr/src/dpx/1.0
With the following files:
dkms.conf
Makefile
dpxmtt.c
lib.a
dkms.conf file is like this:
MAKE="make"
CLEAN="make clean"
BUILT_MODULE_NAME=dpx
BUILT_MODULE_LOCATION=src/
DEST_MODULE_LOCATION=/kernel/drivers/input/touchscreen
PACKAGE_NAME=dpxm
PACKAGE_VERSION=1.0
REMAKE_INITRD=yes
And the makefile is like this:
EXTRA_CFLAGS+=-DLINUX_DRIVER -mhard-float
obj-m += dpx.o
dpx-objs:= dpxmtt.o ../source/lib.a
all:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules
clean:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean
The ../source/lib.a is an hack since when the makefile is invoked by the dkms building system it was saying that it couldn't be found in directory (the build directory), but since it was being copied to the source directory, i'm referencing it relatively.
When I call
sudo dkms build -m dpx -v 1.0
The result is almost perfect:
santos#NS-PC:~$ sudo dkms build -m dpx -v 1.0
Kernel preparation unnecessary for this kernel. Skipping...

The module was built correctly but it ends with the error:
ERROR (dkms apport): binary package for dpx: 1.0 not found
Error! Build of dpx.ko failed for: 3.0.0-14-generic (i686)
And I don't know what it means. Does anybody know?
Using:
$(shell uname -r)
in the Makefile it might be also wrong! The "shell uname -r" refers to the currently running kernel, but the main reason to use the dkms it's because it offers an automated method to recompile the kernel modules that reside outside of the kernel tree for every newly installed kernel. What i mean is that the Makefile might refers to a different kernel which the dkms is building the module for.
Use:
${kernelver} instead.
I had a similar problem. I think your BUILT_MODULE_LOCATION is set incorrectly to the src directory. It should be set in your example to the current directory, or you can just omit this variable and dkms would default to the current directory.
