More testing seems to indicate that check_symbol_exists won't find any typedef defined in headers.
Looking a the CheckSymbolExists.cmake file, the following .c is generated as a test: #include <runetype.h> void cmakeRequireSymbol(int dummy,...) { (void)dummy; } int main() { #ifndef wint_t cmakeRequireSymbol(0, &wint_t); #endif return 0; } Unfortunately, you can't use #ifndef to test for the existence of a typedef, hence you get a compile failure and the result of the test is false. Is there another check which is typedef/define agnostic? I'm sure I could write my own, but this seems like it should be included in the standard cmake library. -- Aaron Turner http://synfin.net/ http://tcpreplay.synfin.net/ - Pcap editing and replay tools for Unix & Windows Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety. -- Benjamin Franklin _______________________________________________ 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
