I'm using CMake (2.8.10.2) in an embedded project, which so far has worked great. However, now I'm trying out a newer version of the compiler and I'm running into issues with '-rdynamic' when CMake checks the compiler. The issue I see is this:
~~~~ -- Check for working C compiler: /opt/rt-tools/compilers/arm-eabi/bin/arm-eabi-gcc -- broken CMake Error at /usr/share/cmake-2.8/Modules/CMakeTestCCompiler.cmake:61 (message): The C compiler "/opt/rt-tools/compilers/arm-eabi/bin/arm-eabi-gcc" is not able to compile a simple test program.

I found an old issue that seems related, http://www.cmake.org/Bug/view.php?id=9985, it's been closed for years. Is there some way to remove the flag on compiler checks, or is my only option to disable compiler checks alltogether? /M -- Magnus Therning OpenPGP: 0xAB4DFBA4 email: [email protected] jabber: [email protected] twitter: magthe http://therning.org/magnus -- Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake
