#6 Common-C++: MinGW make fault

[Anonymous]

Hello,
I'm try to build the Common-C++ libs using MinGW and
MSYS on Microsoft Windows. The configure script
seems to work well but when make with the
w32/Makefile.gcc I got these errors:

$ make -f Makefile.gcc

This seems to be some kind of define or configuration
missing parameter. Can you help me, please?

Thank you.

It has been a long time since I tried mingw32...snprintf may be defined in
cstdio/stdio.h, or maybe in another header? The other option is that you may
be able to -Dsnprintf=_snprintf since the w32 c runtime library uses _snprintf
instead of snprintf.

Adding -Dsnprinf=_snprinf in the CPPFLAGS define within the
w32/Makefile.gcc doesn't change the result. The snprinf
seems to be defined within the cstdio header file but I'm not
sure.

Solved!
Add -D_snprintf=snprintf (NOT -Dsnprintf=_snprintf) to the
CPPFLAGS declaration in w32/Makefile.gcc

Now I got another frustrating error:

Please, help me! :)

This is now fixed, and works rather well at least on gnu/linux hosted mingw32 cross compilers.
