CMake uses gcc from devtoolset but links against wrong libgcc and libstd++ - Stack Overflow

This feature allows you to use modern C++ standards, and produce a binary which can be executed in the original OS (CentOS/RHEL) w/o any additional "redistributable" shared libraries.

JFYI, if you use strip, make sure you use it from DTS and not the "native" one (shipped in binutils from the OS)! Otherwise, really bad things can happen.

Can CMake automatically detect RH devtoolset-7? - Usage - CMake Discourse

June 4, 2021 - I am building on Centos 7, which natively has gcc 4.8.5, using CMake 3.16.6 and Ninja. My code requires gcc 7 so I specify RH devtoolset-7: -DCMAKE_CXX_COMPILER=/opt/rh/devtoolset-7/root/usr/bin/g++ My code checks the compiler version as follows: if("${CMAKE_CXX_COMPILER_ID}" STREQUAL "GNU") if (CMAKE_CXX_COMPILER_VERSION VERSION_LESS 5.4.0) message(FATAL_ERROR "g++ (GCC) version must be at least 5.4.0 (detected ${CMAKE_CXX_COMPILER_VERSION}).

CentOS 7: installed devtoolset-7, but GCC 7.8 is using GCC 4.8 installation's old C++ include files - Super User

1 of 1

Figured it out. cmake was using an old version of gcc/g++, not the one that my command line was picking up when I ran gcc or g++ myself. So, I had to export CC and CXX to the appropriate paths before running cmake.

export CC=/opt/rh/devtoolset-7/root/usr/bin/gcc
export CXX=/opt/rh/devtoolset-7/root/usr/bin/g++
cmake3 -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release ..

Previously, I was only running the last line above.

Please note that the executable is called cmake3 on Red Hat 7 / CentOS7. On Red Hat 7 / CentOS7 mantid uses devtoolset-7. This means that you need to wrap your initial cmake command as scl enable devtoolset-7 "cmake3 /path/to/source".

I think the problem is with the more recent versions of binutils. I tried to compile OpenFOAM with gcc-4.7.2 using binutils 2.23.2 and got the same error with cmake. I tried versions 2.8.3, 2.8.4 and the most recent 2.8.12.1 - all without success (same keypad error). However I later succeeded in compiling cmake-2.8.3 (using gcc 4.7.3 but I think 4.7.2 will work as well) but using binutils 2.23 (not my idea I would add). You can follow the discussion in posts 18-21 http://www.cfd-online.com/Forums/openfoam-installation/121996-error-installing-openfoam-2-2-0-centos-6-4-a.html

in folder OpenFOAM/ThirdParty-2.3.1/cmake-2.8.12.1/Source/CursesDialog in file CMakeLists.txt add the following line

target_link_libraries(ccmake tinfo)

(just below other target_link_libraries commands)
