To compile a libtranslate application, you need to tell the compiler where to find the libtranslate header files and libraries. This is done with the pkg-config utility.
The following interactive shell session demonstrates how pkg-config is used:
$ pkg-config --cflags libtranslate -I/usr/local/include/libtranslate -I/usr/local/include/glib-2.0 -I/usr/local/lib/glib-2.0/include $ pkg-config --libs libtranslate -L/usr/local/lib -ltranslate -lgobject-2.0 -lglib-2.0 -liconv
The simplest way to compile a program is to use the "backticks" feature of the shell. If you enclose a command in backticks (not single quotes), then its output will be substituted into the command line before execution. So to compile a libtranslate Hello World, you would type the following:
$ cc `pkg-config --cflags --libs libtranslate` hello.c -o hello
To compile a libtranslate application using GNU Autoconf and GNU Automake, insert the following line at the appropriate place in the configure.ac file:
PKG_CHECK_MODULES(LIBTRANSLATE, libtranslate,, [AC_MSG_ERROR([unable to find libtranslate])])
and insert the following lines in the appropriate Makefile.am file:
bin_PROGRAMS = hello hello_SOURCES = hello.c hello_CPPFLAGS = $(LIBTRANSLATE_CFLAGS) hello_LDFLAGS = $(LIBTRANSLATE_LIBS)
