When attempting to build matplotlib 0.98.5.2 on Solaris 10 using GCC 4.3.3, I get an error: ttconv/pprdrv_tt2.cpp: In member function ‘void GlyphToType3::stack(TTStreamWriter&, int)’: ttconv/pprdrv_tt2.cpp:107: error: ‘class TTStreamWriter’ has no member named ‘putc’ So I tried invoking GCC with the -E flag to get the output of the preprocessor and I see that line 107 of pprdrv_tt2.cpp gets rewritten to: stream.putc(('{'), (&__iob[1])); so it seems that something in GCC 4.3.3 on Solaris is defining a putchar macro that is doing this, but not correspondingly being applied to the pprdrv.h. Searching the list archives, I see that back in July & August, 2008 there was a brief thread between Peter Norton and Mike Droettboom about this and a proposal was made to rename TTStreamWriter::putchar to TTStreamWriter:put_char. I just looked at the trunk and it looks like this has never been done. Was there some other work-around that didn't make it into the thread that obviated the need for the mentioned change? I can confirm that the renaming of putchar to put_char does solve the problem. I've attached a patch file, though it is against 0.98.5.2. -- Dave
