Re: GMP and MPFR fails

[Vincent DIEMUNSCH]

Thanks Ryan for your help !

The tests seem to pass. For instance for MPFR :
DEBUG: No need to upgrade! gmp 5.0.1_0 >= gmp 5.0.1_0
--->  Computing dependencies for mpfr
DEBUG: Searching for dependency: gmp
DEBUG: Found Dependency: receipt exists for gmp
DEBUG: Executing org.macports.main (mpfr)
DEBUG: Skipping completed org.macports.fetch (mpfr)
DEBUG: Skipping completed org.macports.checksum (mpfr)
DEBUG: setting option extract.cmd to /usr/bin/bzip2
DEBUG: Skipping completed org.macports.extract (mpfr)
DEBUG: Skipping completed org.macports.patch (mpfr)
DEBUG: Skipping completed org.macports.configure (mpfr)
DEBUG: Skipping completed org.macports.build (mpfr)
DEBUG: Skipping completed org.macports.test (mpfr)

Then I tried to update the libgmp and libmpfr files in XCode's
"Link Binary With Library" and I find odd things :
- when I link with the ".a" it doesn't work properly
- when I link with the ".dylib" IT IS OK but in 2 different projects
I have two different names : libmpfr.dylib and libmpfr.1.dylib and
I do not manage to find both in the finder...

What should I use ? ".a", ".dylib" ?
Do I need to delete and add new links in XCode each time I update
the lib in MacPorts ?
