CMake Error #276

Open dingetje opened 1 year ago

dingetje commented 1 year ago

I'm trying to build this project on a RHEL7 machine, but CMake fails with this error:

./builds.sh cmake
Creating build_c++98_gcc-4.4
CMake Error at /usr/local/share/cmake-3.20/Modules/CMakeDetermineCXXCompiler.cmake:48 (message):
  Could not find compiler set in environment variable CXX:

  g++-4.4.

Call Stack (most recent call first):
  CMakeLists.txt:24 (project)

CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
-- Configuring incomplete, errors occurred!

I am not familiar with CMake, and have no idea why g++ 4.4 is even tried, the g++ compiler version is:

$ g++ --version

$ env | grep CXX
CXX=/usr/bin/g++
CMAKE_CXX_COMPILER=/usr/bin/g++

Work around is to explicitely add these lines to the CMakeLists.txt:

set( CMAKE_CXX_COMPILER "/usr/bin/g++" )
set( CMAKE_C_COMPILER "/usr/bin/gcc" )
