Re: [wx-dev] fontenum.cpp wxFontEnumeratorProc declaration build error
Dave Trollope
I too was using the canned files, not ./configure etc.
My build command was :
gcc --pipe -fvtable-thunks -c -D_X86_=1 -DWIN32 -D_WIN32 -DWINVER=0x0400
-D__WIN95__ -D__GNUWIN32__ -D__WIN32__ -I../../include
-I../../contrib/include -I../../src/png -I../../src/jpeg
-I../../src/zlib -I../../src/xpm -I../../src/tiff
-I../../include/wx/msw/gnuwin32 -DSTRICT -D__WXMSW__ -D__WINDOWS__
-D__WXDEBUG__ -Wall -fno-pcc-struct-return -O2 -fno-rtti
-fno-exceptions -o ../../src/msw/fontenum.o ../../src/msw/fontenum.cpp
so thats pretty similar.
I did in a separate dir download the CVS version and copy the file from
that that has #if defined (not #elif as you describe).... but those
changes didn't seem to make much difference although I realise there
could be other changes in the macro defs that I didn't copy.
I'll try to get the CVS version compiled and see if I have the same
problem - may not be tonight though.
Will get back to you about that tomorrow (or day after) - thanks for the
speedy response.
