• Programming with gtkmm 4
• Básico

Although we have shown the compilation command for the simple example, you really should use the automake and autoconf tools, as described in "Autoconf, Automake, Libtool", by G. V. Vaughan et al. The examples used in this book are included in the gtkmm-documentation package, with appropriate build files, so we won't show the build commands in future. You'll just need to find the appropriate directory and type make.

Para simplificar a compilação, usaremos o pkg-config, que está presente em todas as instalações do gtkmm (se instaladas apropriadamente). Esse programa "sabe" quais opções de compilador são necessárias para compilar os programa que usam gtkmm. A opção --cflags faz com que o pkg-config emita uma lista de diretórios de inclusão para o compilador buscar; a opção --libs solicita a lista de bibliotecas às quais o compilador deve vincular e os diretórios onde achá-los. Experimente executá-lo no seu prompt do shell para ver os resultados no seu sistema.

However, this is even simpler when using the PKG_CHECK_MODULES() macro in a standard configure.ac file with autoconf and automake. For instance:

PKG_CHECK_MODULES([MYAPP], [gtkmm-4.0 >= 4.8.0])

gtkmm-4.0 is the name of the current stable API. There are older APIs called gtkmm-2.4 and gtkmm-3.0 which install in parallel when they are available. There are several versions of gtkmm-2.4, such as gtkmm 2.10 and there are several versions of the gtkmm-3.0 API. Note that the API name does not change for every version because that would be an incompatible API and ABI break. There might be a future gtkmm-5.0 API which would install in parallel with gtkmm-4.0 without affecting existing applications.

Note that if you mention extra modules in addition to gtkmm-4.0, they should be separated by spaces, not commas.

The GNU site has more information about autoconf and automake.

If you start by experimenting with a small application that you plan to use just for yourself, it's easier to start with a Makefile similar to the Makefile.example files in the Building applications chapter.
