Hello all, I'm trying the Hello pass example in the "Writing an LLVM Pass" webpage ( http://llvm.org/docs/WritingAnLLVMPass.html#basiccode ). I followed the instructions to compile (with gcc-4.2) the Hello.cpp, but I got the compile errors: Hello.cpp:20: error: expected identifier before string constant Hello.cpp:20: error: expected ',' or '...' before string constant Hello.cpp:20: error: expected constructor, destructor, or type conversion before ';' token which is the line "INITIALIZE_PASS(Hello, "Hello", "Hello World Pass", false, false);" in the code. Could any one help me with this? Thank you very much! Best, Daniel -------------- next part -------------- An HTML attachment was scrubbed...

Use the 2.7 docs instead: http://llvm.org/releases/2.7/docs/WritingAnLLVMPass.html#basiccode Trevor
