Compiler Linking Question on Linux

Compiler Linking Question on Linux

[Michael Wieher]

Strange question.

When I compile, I can't find certain libraries.  For instance,

/usr/include/glibmm/ustring.h:24:26: error: glib/gmacros.h: No such
file or directory

when I examine the directory I find

drwxr-xr-x  4 root root   4096 Jan 14 16:49 glib-2.0

and I am logged on as root.

now, I recall versioning vaugely but I thought make would be able to
realize glib-2.0 referenced 'glib' when compiling.

is there something I need to do so my compiler can figure out where
these libraries are?

thanks.

You may need to add a -I (include path) or -L (library link path) option to
your compiler.  

Since you didn't give specific paths, we'll just guess and say that glib is
a directory under /usr/include.  So add a -I/usr/include/glib
-L/usr/include/glib to your compile line.

Also check the #include lines in your header files and make sure they're
indicating the correct path.  If the real directory is /usr/include/glib-20.
and the header files #include <glib/gmacros.h> instead of #include
<glib-2.0/gmacros.h> then there is a problem.
