CMake compile error in Ubuntu 16.04 - broken C Compiler

ashwath129 opened this issue · 1 comments

OS: Ubuntu 16.04
GCC Version - 7.5
G++ Version - 7.5
CMake version - 3.5.1

When trying to compile approxmc 4.0.0 and as I run the commands,

git clone https://github.com/msoos/cryptominisat
cd cryptominisat
mkdir build && cd build
cmake ..

When i execute the cmake command I get the following error,

-- The CXX compiler identification is GNU 7.5.0
-- Check for working CXX compiler: /usr/bin/c++
-- Check for working CXX compiler: /usr/bin/c++ -- works

CMake Error at /usr/share/cmake-3.5/Modules/CMakeTestCCompiler.cmake:61 (message):

  It fails with the following output:

I have tried to build it directly by using -DCMAKE_C_COMPILER=gcc along with the cmake command. The 'build-essentials' package is also the latest.
It does however work with Ubuntu version 18.04 and Cmake version v3.10.2.

Was wondering whether there is a specification for running/compiling the source (whether you need a specific version of OS/Cmake/Any prerequisite). Or is it targeting a specific piece of code in the source, that needs to be changed ?
Thanks!

Hi,

Unfortunately, this has nothing to do with ApproxMC. The cmake setup stops because your compiler is broken -- this is a basic check by cmake, I literally cannot even disable it. Either your cmake, gcc, or other essential setup of your system is broken. I suggest re-building your system, since it's Ubuntu 16.04, which is quite old. New long-term-support LTS version is 20.04. That's a good upgrade.

Sorry I cannot help, but this has nothing to do with ApproxMC, CryptoMiniSat, or indeed anything I have control over. Please check some forums or upgrade to 20.04 LTS.

Good luck,

Mate
