pkgconfig 0.24 adds extra escaping

[xcingix@…]

I'm having trouble installing GMPC via MacPorts.

We suspected that libproxy failed due to xulrunner not being installed. Unfortunately, we couldn't get xulrunner to install on that system either (i've emailed jeremyhu).

Nothing to do with missing dependencies.

Syntax error in cmake code at

    :102

  when parsing string

    -DORBIT2\=1;-D_REENTRANT;-I/opt/local/include/gconf/2;-I/opt/local/include/orbit-2.0;-I/opt/local/include/dbus-1.0;-I/opt/local/lib/dbus-1.0/include;-I/opt/local/include/glib-2.0;-I/opt/local/lib/glib-2.0/include;-I/opt/local/include

  Invalid escape sequence \=

Could be a problem with cmake, pkgconfig or orbit2. The recent pkgconfig update could be at least the proximate cause.

Whatever generates that string does so incorrectly ... the compiler definition should be -DORBIT2=1. The escaped equal sign is the source of the error.

Really seems to be the fault of pkg-config:

$ grep Cflags /opt/local/lib/pkgconfig/ORBit-2.0.pc
Cflags: -I${includedir}/orbit-2.0 -DORBIT2=1

$ pkg-config --cflags ORBit-2.0
-DORBIT2\=1 -D_REENTRANT -I/opt/local/include/orbit-2.0 -I/opt/local/include/glib-2.0 -I/opt/local/lib/glib-2.0/include -I/opt/local/include

Agreed, pkgconfig's error. I see a ​discussion about it on their mailing list with a promise that version 0.25 will be out shortly to fix it.

Fixed by updating to 0.25 in r68187.
