How to find arm-apple-darwin#-llvm-gcc-4.2 compiler on Xcode 5?

问题 I am tying a cross compilation and for that I need to find where Xcode have placed the arm-gcc compiller. It used to be in /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin10-llvm-gcc-4.2 but it has vanished in Xcode 5. Any Ideas? 回答1: Use the newer clang compiler instead like this: - for CC: xcrun -find -sdk iphoneos clang for CXX: xcrun -find -sdk iphoneos clang++ 回答2: It's usually best to use xcrun -find to dynamically locate Xcode

Are llvm-gcc and clang binary compatible with gcc? - particularly mingw gcc on Windows

If I build a static library with llvm-gcc, then link it with a program compiled using mingw gcc, will the result work? The same for other combinations of llvm-gcc, clang and normal gcc. I'm interested in how this works out on Linux (using normal non-mingw gcc, of course) and other platforms as well, but the emphasis is on Windows. I'm also interested in all languages, but with a strong emphasis on C and C++ - obviously clang doesn't support Fortran etc, but I believe llvm-gcc does. I assume they all use the ELF file format, but what about call conventions, virtual table layouts etc? Yes, for C

No code coverage with Mac OS X Lion and XCode 4 / llvm-g++-4.2

问题 Other people have reported not being able to generate code coverage with XCode 4, but I find not only can I not do it from within XCode 4, I can't do it even with a simple toy program from the command line. I followed the examples given here and here, which led me to create this cov.c file: #include <stdio.h> int main (void) { int i; for (i = 1; i < 10; i++) { if (i % 3 == 0) printf("%d is divisible by 3\n", i); if (i % 11 == 0) printf("%d is divisible by 11\n", i); } return 0; } I then used
