Compilation issues on Ubuntu 22.04

[vikaskurapati]

Hi,

I am facing an issue with compilation/installation of core on my local machine. I got errors due to warnings earlier and then I removed '-Werrors' from core/cmake/bob.cmake. Now I encounter the following error:

/usr/bin/ld: ../apf/libapf.a(apfGeometry.cc.o): undefined reference to symbol 'acos@@GLIBC_2.2.5' /usr/bin/ld: /lib/x86_64-linux-gnu/libm.so.6: error adding symbols: DSO missing from command line collect2: error: ld returned 1 exit status make[2]: [test/CMakeFiles/verify.dir/build.make:112: test/verify] Error 1 make[1]: [CMakeFiles/Makefile2:1119: test/CMakeFiles/verify.dir/all] Error 2 make: *** [Makefile:146: all] Error 2

It seems to be some issue with linking the math library.

I tried to sort that out with 'target_link_libraries(core INTERFACE ${MATH_LIBRARY})' in CMakeLists.txt. But that just gives a lot of undefined references error.

Could you please help me figure this out?

Hmmm. What compiler and version of the compiler are you using?

[vikaskurapati]

gcc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0.

[cwsmith]

Great. Thanks. I'm pretty sure we have built with GCC > 11 before. What was your cmake configure command?

[vikaskurapati]

I tried a bunch and after a lot of googling and tries, I stand currently at this:

CC=mpicc CXX=mpicc FC=mpif90 cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=$HOME -DCMAKE_CFLAGS="-lm" -DCMAKE_EXE_LINKER_FLAGS="-dynamic -lm"

[cwsmith]

OK. Thanks.

You can revert the edit to cmake/bob.cmake and suppress warnings/errors with -DSCOREC_CXX_WARNINGS=off passed to the cmake configure command. Ideally, we can fix those warnings though.

I just built with GCC 13.1.1 20230429 using the following commands without any obvious issues. Can you try these?

git clone git@github.com:SCOREC/core.git
cmake -S core -B buildCore -DCMAKE_CXX_COMPILER=mpicxx -DCMAKE_C_COMPILER=mpicc
cmake --build buildCore -j8

A build with optimizations enabled also succeeds without issues:

git clone git@github.com:SCOREC/core.git
cmake -S core -B buildCoreOpt -DCMAKE_CXX_COMPILER=mpicxx -DCMAKE_C_COMPILER=mpicc -DSCOREC_CXX_OPTIMIZE=ON
cmake --build buildCoreOpt -j8

Hi,

thank you very much! This works. However, when I try to do 'make install' with this, the following error comes up

CMake Error at test/cmake_install.cmake:1684 (file): file INSTALL cannot find "/media/vikaskurapati/external/4th_Semester/core/pumi-meshes/pipe/pipe.dmg": No such file or directory. Call Stack (most recent call first): cmake_install.cmake:92 (include)

[cwsmith]

Great!

Ahh, so it is trying to install input files for testing from the pumi-meshes submodule.

Try the following:

git clone --recursive git@github.com:SCOREC/core.git
cmake -S core -B buildCore -DCMAKE_CXX_COMPILER=mpicxx -DCMAKE_C_COMPILER=mpicc -DCMAKE_INSTALL_PREFIX=$PWD/buildCore/install
cmake --build buildCore -j8 --target install

This adds --recursive to download the submodule, adds -DCMAKE_INSTALL_PREFIX=$PWD/buildCore/install to specify where the installed files should go, and --target install to run the install after building.

[vikaskurapati]

It works now! Thank you very much!
