libexpat.dylib was built for i386 which is not the architecture being linked

I get the following error when I tried to install fontconfig

I checked the main.log file, and it showed

expat is required. or try to use --enable-libxml2

But when I tried to rebuild expat and xml2, it seems that they both depend on fontconfig and the same error when building fontconfig shows up again.

port -v installed

The error in the config.log is:

ld: warning: ignoring file /opt/local/lib/libexpat.dylib, file was built for i386 which is not the architecture being linked (x86_64): /opt/local/lib/libexpat.dylib

Why is this the case? How did this happen? Did you install some third-party software that overwrote some of your MacPorts-installed software?

The solution to this particular error is to rebuild expat, which you can do by running:

sudo port clean expat
sudo port -n upgrade --force expat

However, if your expat was overwritten, who knows how many of your other ports have been overwritten. It might be safest and easiest to uninstall all ports, and MacPorts itself, and remove the /opt/local directory entirely, as per our ​uninstall instructions, then reinstall MacPorts and the ports you want.

Replying to ryandesign@…:

I uninstalled it and installed again. Everything runs well now. Thanks!
