Error linking GLEW #986

Open roastduck opened 1 year ago

roastduck commented 1 year ago

Hi, I am building instant-ngp but it reports linking error against GLEW. In my case, CMake has already found GLEW (GLEW 2.2.0 installed via Spack):

-- Found GLEW: /home/spack/spack/opt/spack/linux-debian11-zen2/gcc-10.2.1/glew-2.2.0-ag6zl4i4osht5c72l27jxewoa5it3oqf/lib/cmake/glew/glew-config.cmake

But it is not linked successfully:

I notice the linking command here does not include -LGLEW at all. Is it by design or a bug?

I had a similar issue where the compiler could not properly link to GLEW although it was installed.

I'm working on a cluster without sudo privilege and had to compile glew by hand. However, even after adding it to my envvars it wouldn't be found when compiling.

So I just manually set it in the CMakeLists.txt:

You can set the GLEW_INCLUDE_DIRS and BLEW_LIBRARIES manually before adding these into NGP. For instance you can add these two lines:

set(GLEW_INCLUDE_DIRS "/path-to-your-glew/glew-2.1.0/build/cmake/install/include")
set(GLEW_LIBRARIES "/path-to-your-glew/glew-2.1.0/build/cmake/install/lib/libGLEW.so")

right before L153/154

list(APPEND NGP_INCLUDE_DIRECTORIES ${GLEW_INCLUDE_DIRS})
list(APPEND` NGP_LIBRARIES GL ${GLEW_LIBRARIES} $<TARGET_OBJECTS:glfw_objects>)

This is pretty hacky but worked in my case.

Chiming in that I also encountered the exact same issue, and had to follow the same steps that @vincentcartillier suggested above. This resolved the issue for me.

It's unclear what caused this issue, but uninstalling and reinstalling using apt was not effective. One thing I do notice is that whenever I install GLEW using sudo apt-get install libglew-dev, the libGLEW.so library file appears to be a broken symlink.
