Re: Glib::ustring in mingw

[Edscott Wilson <edscott wilson garcia gmail com>]

Problem solved, more or less. The issue is with gcc compiler. Apparently the gtkmm bundle package is build with gcc-4.6.2, and some hack or other is done to get glib/glibmm to compile.

If you try to compile and link your program with a different gcc version (I tried 4.7.0 and 4.7.2) the ustring constructor in glibmm is broken and will invariably lead to SEGV. Using a mingw with the packaged compiler and tools, there is no problem with Glib:ustring.

So the quick fix is to install mingw with the packaged gcc (4.6.2) and use this to build gtkmm packages. Plain gtk+ will most probably work correctly with gcc-4.7.2 or later.

Boa noite!
Tive problemas com a convers￣o de tipos no in￭cio mas o Glib::ustring resolveu tudo sem problemas, a nica altera￧￣o que tive que fazer para sistemas em win32 foi acrescentar a biblioteca correspondente ao SO <windows.h>.
Segue o techo que usei para testar:
#if  defined(__WIN32__) || defined(__WIN__)
#include <windows.h>
#endif

Para esclarecer tenho um sistema de Fluxo de Caixa rodando em ambos os sistemas feito em GTKmm com acesso a banco de dados MYSQL e POSTGRESQL.

Att.

Good night!
I had problems with type conversion in the beginning but the Glib :: ustring solved everything without problems, the only change I had to do was to add win32 systems in the library corresponding to SO <windows.h>.
Follows the techo I used to test:
# if defined (__WIN32__) | | defined (__WIN__)
# include <windows.h>
# endif

To have a clear system cash flow running on both systems made ??in GTKmm with access to MYSQL database and POSTGRESQL.
