Yes, that's it. Thanks for the info!

But I'm absolutely fine with Alexander's statement that this is a (very low priority) bug. This means that my understanding of CheckSymbolExists and CheckCXXSymbolExists is not totally wrong and that it is basically ok to make a project without the C language being enabled. Sorry about the noise ;-) Cheers, Johannes -- 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

Yes, but I'd consider it a very low severity bug.

Really? Seconds? I mean the toolchain-stuff in CMake is more or less hardcoded anyway, there's not a lot of runtime-checking going on there. > It turns out that without C enabled, standard modules like FindKDE, FindQt4 > and FindJPEG don't run because they use the CheckSymbolExists module. > > I'm wondering if this counts as a bug in FindQt4 and FindKDE, because after > all these two projects are C++, so any platform test should IMO be using the > same compiler as the build-process does? Well, on all platforms I know it actually does use the same compiler, just under a different name :P Also some of the platforms don't have a C compiler at all anyway (or at least none that you'd call a proper C compiler by todays standards). That being said, technically you're correct, they should be using CheckCXXSymbolExists instead.
