Unable to build against GLEW on OS X 10.9 Mavericks
c, glew, macos, opengl, xcode
Solution
Like rpowell mentioned above, the way to avoid this error on recent versions of XCode is by doing the following: PS: (I solved this on my project running XCode 8.2.1 and OS X El Capitain 10.11.6):
On the Project tab, select your project by single-clicking on its name (It is the blue icon in my example)
After that, single-click on Build Setting tab and make sure you have the following options selected: All and Combined
Finally, search for 'enable modules' on the search menu, and when it shows Enable Modules(C and Objective-C), just mark no
After that you should be 'hopefully' able to compile your code and get it running.
Problem
I'm trying to set up a program using GLEW on OS X 10.9 with Xcode 5.1, but upon trying to build it, I get a huge amount of errors originating from `glew.h`: ``` Build target HelloGL CompileC /Users/rpowell/Library/Developer/Xcode/DerivedData/HelloGL-hkapwtszjscyivcyxfphwntzlxmw/Build/Intermediates/HelloGL.build/Debug/HelloGL.build/Objects-normal/x86_64/main.o HelloGL/main.c normal x86_64 c com.apple.compilers.llvm.clang.1_0.compiler cd /Users/rpowell/Projects/HelloGL export LANG=en_US.US-ASCII /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang -x c -arch x86_64 -fmessage-length=0 -fdiagnostics-show-note-include-stack -fmacro-backtrace-limit=0 -std=gnu99 -fmodules -fmodules-cache-path=/Users/rpowell/Library/Developer/Xcode/DerivedData/ModuleCache -Wno-trigraphs -fpascal-strings -O0 -Wno-missing-field-initializers -Wno-missing-prototypes -Werror=return-type -Werror=deprecated-objc-isa-usage -Werror=objc-root-class -Wno-missing-braces -Wparentheses -Wswitch -Wunused-function -Wno-unused-label -Wno-unused-parameter -Wunused-variable -Wunused-value -Wempty-body -Wconditional-uninitialized -Wno-unknown-pragmas -Wno-shadow -Wno-four-char-constants -Wno-conversion -Wconstant-conversion -Wint-conversion -Wbool-conversion -Wenum-conversion -Wshorten-64-to-32 -Wpointer-sign -Wno-newline-eof -DDEBUG=1 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk -fasm-blocks -fstrict-aliasing -Wdeprecated-declarations -mmacosx-version-min=10.9 -g -Wno-sign-conversion -I/Users/rpowell/Library/Developer/Xcode/DerivedData/HelloGL-hkapwtszjscyivcyxfphwntzlxmw/Build/Intermediates/HelloGL.build/Debug/HelloGL.build/HelloGL.hmap -I/usr/local/include -I/Users/rpowell/Library/Developer/Xcode/DerivedData/HelloGL-hkapwtszjscyivcyxfphwntzlxmw/Build/Products/Debug/include -I/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include -I/Users/rpowell/Library/Developer/Xcode/DerivedData/HelloGL-hkapwtszjscyivcyxfphwntzlxmw/Build/Intermediates/HelloGL.build/Debug/HelloGL.build/DerivedSources/x86_64 -I/Users/rpowell/Library/Developer/Xcode/DerivedData/HelloGL-hkapwtszjscyivcyxfphwntzlxmw/Build/Intermediates/HelloGL.build/Debug/HelloGL.build/DerivedSources -F/Users/rpowell/Library/Developer/Xcode/DerivedData/HelloGL-hkapwtszjscyivcyxfphwntzlxmw/Build/Products/Debug -MMD -MT dependencies -MF /Users/rpowell/Library/Developer/Xcode/DerivedData/HelloGL-hkapwtszjscyivcyxfphwntzlxmw/Build/Intermediates/HelloGL.build/Debug/HelloGL.build/Objects-normal/x86_64/main.d --serialize-diagnostics /Users/rpowell/Library/Developer/Xcode/DerivedData/HelloGL-hkapwtszjscyivcyxfphwntzlxmw/Build/Intermediates/HelloGL.build/Debug/HelloGL.build/Objects-normal/x86_64/main.dia -c /Users/rpowell/Projects/HelloGL/HelloGL/main.c -o /Users/rpowell/Library/Developer/Xcode/DerivedData/HelloGL-hkapwtszjscyivcyxfphwntzlxmw/Build/Intermediates/HelloGL.build/Debug/HelloGL.build/Objects-normal/x86_64/main.o In file included from /Users/rpowell/Projects/HelloGL/HelloGL/main.c:1: /usr/local/include/GL/glew.h:15043:17: error: declaration of 'PFNGLCOPYTEXSUBIMAGE3DPROC' must be imported from module 'OpenGL.GL3' before it is required GLEW_FUN_EXPORT PFNGLCOPYTEXSUBIMAGE3DPROC __glewCopyTexSubImage3D; ^ In module 'OpenGL' imported from /usr/local/include/GL/glew.h:1186: /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/System/Library/Frameworks/OpenGL.framework/Headers/gl3.h:1762:25: note: previous declaration is here typedef void (APIENTRYP PFNGLCOPYTEXSUBIMAGE3DPROC) (GLenum target, GLint level, GLint xoffset, GLint yoffset, GLint zoffset, GLint x, GLint y, GLsizei width, GLsizei height); ^ In file included from /Users/rpowell/Projects/HelloGL/HelloGL/main.c:1: /usr/local/include/GL/glew.h:15049:17: error: unknown type name 'PFNGLCLIENTACTIVETEXTUREPROC'; did you mean 'PFNGLACTIVETEXTUREPROC'?
