It appears from comparison between the good and bad linking commands above
that the plplot-tcl.pc file should transform
/System/Library/Frameworks/tcl.framework ==> -framework tcl
and similarly for tk.
Also, all the direct specification of *.dylib libraries should be
transformed into the -L -l form. (This is the form that worked for the good
linking command above. Also, my experience with Linux is pkg-config
handles specifying libraries with -L and -l options much better than using
the actual library name.)
The only potential problem with these changes is when you tried that first
transformation by hand editing plplot-tcl.pc, one of the essential
"-framework" strings was not emitted by pkg-config. That's really peculiar.
Could you try the following simple example to see what you get on your system?
*****test.pc (simplest possible example)
[EMAIL PROTECTED]> cat test.pc
Name:
Description:
Requires:
Version:
Libs: -framework tcl -framework tk
Cflags:
On my Linux system both -framework options are emitted properly by pkg-config:
[EMAIL PROTECTED]> PKG_CONFIG_PATH=. pkg-config --libs test
-framework tcl -framework tk
If you also get the right result for this simple case, then it's possible
that the *.dylib form of library name was confusing pkg-config in the more
complicated plplot-tcl.pc case. To test that possibility, I have gone ahead
and made the above two transformations (framework and *.dylib) in CVS. Will
you please give that changed version a try?
