Hi Juergen,

Thank you for your answer.

Apparently these are just two locations for header files. Here's the
complete .pc.in file:

===
prefix=@prefix@
exec_prefix=@exec_prefix@
libdir=@libdir@
includedir=@includedir@
libincludedir=@libdir@/@PACKAGE@/include

zipcmp=@prefix@/bin/zipcmp

Name: libzip
Description: library for handling zip archives
Version: @VERSION@
Libs: -L${libdir} -lzip @LIBS@
Cflags: -I${includedir} -I${libincludedir}
===

This is probably not very common (they could have just used includedir
for all paths) but as far as I can see it is valid syntax.

After some digging (the post-install processing does not seem to be
documented anywhere) I already found where ptxdist is patching these
files (ptxd_make_world_install_mangle_pc.awk), which was my original
question. Now the question is, should this awk script handle all paths
in the .pc file? Or only the "common cases" prefix / exec_prefix /
libdir / includedir?

Thank you,

Guillermo
