It spends me almost 1 week to find out the reason for the
following error msg generated by Xcode (Mountain Lion MBA). clang: error:
linker command failed with exit code 1 (use -v to see invocation). The reasons
for this error is that 2 duplication function name - "main" using in
the Xcode project. This error occurred when I build and run the c - command
line application Xcode project after imported all the files in "src"
folder at the extracted files of LUA sources, after imported all the files of
project - http-parser in GitHUB.
