[SOLVED] Multiple definition errors when trying to compile Luscus

Hello,

I am trying to compile Luscus 0.8.6 from source in Arch Linux.

My CMake version is 3.19.3, and I am using GNU GCC compilers 10.2.0. I installed all of the required libraries through the pacman package manager.

When I try to make, I get several multiple-definition errors:

I have struggled for a bit trying to set some of these variables to 'extern' in the header files but this only created more problems down the line. I am hoping that someone here who is more experienced with compiling C programs will be able to help!

The output of cmake .. is:

-- Found PkgConfig: /usr/bin/pkg-config (found version "1.7.3")
CMake Deprecation Warning at CMakeLists.txt:3 (cmake_minimum_required):
  Compatibility with CMake < 2.8.12 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.

Re: [SOLVED] Multiple definition errors when trying to compile Luscus

Found the solution.

The default "-fcommon" flag changed to "-fno-common" in GCC 10.
This problem is fixed by adding -DCMAKE_C_FLAGS=-fcommon when running cmake.
