Error in compilation #38

Closed Barnonewdm closed 1 year ago

Barnonewdm commented 1 year ago

Any idea of the following error when performing catkin build --save-config -i --cmake-args -DCMAKE_BUILD_TYPE=Release -DOPENGL_VERSION=430 -DENABLE_NVIDIA_EXT=YES?

/usr/bin/cc  -DCHECK_FUNCTION_EXISTS=pthread_create -rdynamic CMakeFiles/cmTC_3b2ac.dir/CheckFunctionExists.c.o -o cmTC_3b2ac  -lpthreads
/usr/bin/ld: cannot find -lpthreads

The relevant line in the error is: /usr/bin/ld: cannot find -lpthreads

Not sure why it isn't installed with libc, but there are multiple results on google. (It might be sufficient to install libc6-dev, but I didn't check it.)

libc6-dev

Thanks, this lib is installed. Therefore, not working.

Then I have no idea why the linker doesn't find the "posix threads".

I have no further idea...try to google the error: /usr/bin/ld: cannot find -lpthreads. That's what I would do.
