OpenGL.Soil build failure under OSX El Capitan, XCode 8.0 #26

Closed rogermc2 closed 7 years ago

rogermc2 commented 7 years ago

Compilation of the file : /System/Library/Frameworks/CoreGraphics.framework/Headers/CGFont.h fails on my system with: CGFont.h:53:40: error: initializer element is not constant static const CGFontIndex kCGGlyphMax = kCGFontIndexMax;

but kCGFontIndexMax certainly (to me) looks like a constant: typedef unsigned short CGFontIndex; static const CGFontIndex kCGFontIndexMax = ((1 << 16) - 2); static const CGFontIndex kCGGlyphMax = kCGFontIndexMax;

Googling indicates that this failure is not specific to my system. I see that there are two Frameworks/CoreGraphics.framework/Headers/CGFont.h on my system. One in /Library/Developer/CommandLineTools and one in /System/Library with header files dated 8 Feb 2016 in the first and 2 Nov 2016. I am aware that Apple are forever reorganizing there system file structures but haven't been able to find what their current preferred organization is. However, a comparison of the two CGFont.h files indicates no difference at least up to line 53.

Any ideas welcome.

I need more information to reproduce. Building the SOIL test like this:

gprbuild -d -eL -Psoil_test.gpr -XLIBRARY_TYPE=static -XAuto_Exceptions=enabled -XMode=debug -s -XWindowing_System=quartz -p -XGLFW_Version=3

works for me. I am also on El Capitan with Xcode 8 (8A218a).

Thanks flyx. Your command line also worked for me, so I checked: which gcc /usr/bin/gcc It seems the problem is due to my gcc-6.1.0 compiler So I ran gprconfig to select gcc-6.1.0 for Ada and /usr/bin for c. Then added to my GPS Build Target settings: --config=/Ada_Source/config.cgpr soil_test.gpr then built successfully and ran OK. Seems a bug in gcc-6.1.0? I'm currently building gcc-6.3.0 to check for any improvement.

Interesting. I am unsure which gcc my gprbuild uses, my setup is similar to yours. /usr/gcc is 4.2.1 for me, which is the old Apple binary.

For my system: /usr/bin/gcc -v Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1 Apple LLVM version 8.0.0 (clang-800.0.38) Target: x86_64-apple-darwin15.6.0 Thread model: posix InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

gcc-6.3.0 built OK but I had the install prefix wrong. So rebuilding from scratch!
