[Mono-dev] libgdiplus (SVN) fails to compile

[Frederik Carlier]

Hi,

I'm trying to compile the SVN HEAD version of libgdiplus, but it keeps 
failing. Here's what I've done:

svn update
./autogen.sh
make

That yields

The error is caused by these lines in pngconf.h:

fcarlier at col-clt-04:~/development/mono/libgdiplus$ cat 
/usr/include/pngconf.h | head -n 320 | tail
#      undef _BSD_SOURCE
#    endif
#    ifdef _SETJMP_H
     /* If you encounter a compiler error here, see the explanation
      * near the end of INSTALL.
      */
         __png.h__ already includes setjmp.h;
         __dont__ include it again.;
#    endif
#  endif /* __linux__ */

and INSTALL says

If you encounter a compiler error message complaining about the
lines
      __png.h__ already includes setjmp.h;
      __dont__ include it again.;
This means you have compiled another module that includes setjmp.h,
which is hazardous because the two modules might not include exactly
the same setjmp.h.  If you are sure that you know what you are doing
and that they are exactly the same, then you can comment out or
delete the two lines.  Better yet, use the cexcept interface
instead, as demonstrated in contrib/visupng of the libpng distribution.

which leads me to believe that this is a libgdiplus issue (and not a 
libpng issue).

Can anyone else reproduce this issue? If so, is a bug report welcome?

Thanks,

Frederik
