Re: [CMake] check function signature

The simplest way would be to write your own check_function_exists macro in order to check for the specific function declaration. regards -- Bogdan -- 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

Maybe you want check_prototype_definition? Nils On 09/25/2012 03:18 PM, Leif Walsh wrote: I use check_function_exists() to do some platform checking.
