parse error in c2hs in gobject.i

[guest]

This problem was originally reported as a reply of #1099 but I think it's different.

I have the same problem compiling the development version in ubuntu 7.10 32bit with the official binary distribution of ghc 6.8.2, it seems that the problem is that c2hsLocan can't parse glib-objcet.i, i get the following message, trying to make the glib bindings:

I'd like to see this fixed!

Could you run the c2hsLocal command line form above but add a --keep flag and post the gobject.i file?

Thanks, Axel.

Thanks for helping me, this is what i get from the command:

thanks, and sorry for my ugly english

The trouble is that you're working in a spanish locale (which is fine) and that CPP emits non-ASCII characters into the intermediate file (which is not fine). This breaks the lexer of c2hs since it only expects ASCII characters in file names. I have changed this and pushed the changed into the repository. However, I have no way of testing this as my gcc doesn't seem to care about locale settings. Is it possible for you to use the current darcs development snapshot and try again?

May be it's a fix, C code with embed multi-byte-char code is very very rare, and probably illegal.

so the "cpp" output vary in diffrent translation by diffent locale is odd.
