- Reply-to: jay at m5 dot chi dot il dot us
I reported this bug to this mailing list two days ago. Today I
received a diagnosis of the problem from the ImageMagick mailing list.
Here is the mail I received, which also quotes my original bug report:
This really is a g++ bug! The problem is that when large file support
is enabled, Solaris uses macros to map stdio functions that have
64-bit counterparts to the 64-bit counterparts. The g++ headers
intentionally #undef all stdio macros, but this breaks the Solaris
large file API.
When building ImageMagick, you can work around this problem by adding
--disable-largefile to the configure options.
If you really need largefile support, then you can edit
g++'s std_cstdio.h to comment out the #undefs for the problem
functions.
