What is the output of the following?

port installed glib2

You might try rebuilding that.

Replying to macsforever2000@…:

What is the output of the following?

port installed glib2

You might try rebuilding that.

I have glib2-devel installed, I tried uninstalling and reinstalling it but there was no change.

[gabe@…]

I got this working by installing glib2 instead of glib2-devel, then building glib2 of the matching version myself with the prefix as /opt/local, and installing it on top in order to have the headers.

[mf2k (Frank Schima)]

Unlike in Linux, a devel port in Macports has nothing to do with header files.

[ryandesign (Ryan Carsten Schmidt)]

So now you've overwritten some MacPorts-provided files with manually-compiled files. That's not a good idea.

As Frank said above, the "-devel" suffix in MacPorts does not mean it installs headers; rather, all ports install headers, as much as possible. In MacPorts, "-devel" means "this is a development version", as opposed to a stable version. So unless you have a specific need for testing the latest development version of glib2, I suggest you use the glib2 port not the glib2-devel port.

To ensure you have the right versions of the files, and that they were compiled by MacPorts, my recommendation is to uninstall glib2 or glib2-devel, whichever you have installed at the moment:

sudo port -fp uninstall glib2 glib2-devel

-p will proceed even if one of the ports is not installed.

-f will force the uninstallation even if other ports depend on these ports.

Then install glib2:

sudo port clean glib2
sudo port install glib2

I'm pretty sure this is the same error I was getting in #37137
