When the toolchain involved in openscap build does not support C++, the
configure step fails with the following error:
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - failed
-- Check for working CXX compiler: /bin/false
-- Check for working CXX compiler: /bin/false - broken
CMake Error at /usr/share/cmake/Modules/CMakeTestCXXCompiler.cmake:73 (message):
The C++ compiler
"/bin/false"
is not able to compile a simple test program.
It fails with the following output:

The openscap project does not contain any C++ file, and so does not need
a C++ capable compiler. Bring the to-be-integrated-upstream patch
enforcing C language in CMakeLists.txt to prevent this build failure.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at https://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
