[ragel-users] Generated cc failed to compile textmate under OS X ML with latest Xcode command line tools

[191919]

Hi,

I use ragel git to compile textmate in OS X ML 10.8.2 with latest Xcode command line tools but failed.

clang version:

$ clang -v
Apple clang version 4.1 (tags/Apple/clang-421.11.66) (based on LLVM 3.1svn)
Target: x86_64-apple-darwin12.2.1
Thread model: posix

The file which didn't pass the compilation is:

https://github.com/textmate/textmate/blob/master/Frameworks/plist/src/ascii.rl

The compiler generated the following error when compiling the generated ascii.cc file:

/Users/jh/build/TextMate/Frameworks/plist/src/ascii.cc:45:2: error: constant expression evaluates to -1 which cannot be narrowed to type 'char' [-Wc++11-narrowing]

With the release version (ragel-6.7.tar.gz (http://www.complang.org/ragel/ragel-6.7.tar.gz)) of ragel, clang succeeded to compile without any problems.

Hello 191919,

The current git master has undergone some major changes. Thanks for the report I will fix this.
