> PS: Does the linking sequence still include
{{{libpolybori/libpolybori.dylib }}}?
No you fixed that exactly as I asked you. Portage does extra checks for
consistency on libraries on OS X. There are a number of things that aren't
exactly common knowledge to people who don't do a lot of development on OS
X. Technically all libraries on OS X have an rpath which usually is
relative. Look at this document:
[http://blog.onesadcookie.com/2008/01/installname-magic.html]
The solution adopted in portage in a OS X prefix is to make the
install_name absolute which is why at the moment a sage-prefix on OS X is
not relocatable. Now what the QA tool of portage is telling us is that
libpolybori_groebner.dylib is linked to libpolybori/libpolybori.dylib as
in the library contains the name and the path of the library. And we of
course don't want that.
Try the following command:
{{{
otool -L libpolybori_groebner.dylib
}}}
The result here is as follow:
{{{
otool -L libpolybori_groebner.dylib
libpolybori_groebner.dylib:
/Users/frb15/Desktop/Gentoo/usr/lib/libpolybori_groebner.dylib
(compatibility version 0.0.0, current version 0.0.0)
libpolybori/libpolybori.dylib (compatibility version 0.0.0,
current version 0.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
version 111.1.7)
/Users/frb15/Desktop/Gentoo/usr/lib/libm4ri-0.0.20100817.dylib
(compatibility version 0.0.0, current version 0.0.0)
/Users/frb15/Desktop/Gentoo/usr/lib/libgd.2.dylib (compatibility
version 3.0.0, current version 3.0.0)
/Users/frb15/Desktop/Gentoo/usr/lib/gcc/i686-apple-
darwin9/4.2.1/libstdc++.6.dylib (compatibility version 7.0.0, current
version 7.9.0)
/Users/frb15/Desktop/Gentoo/usr/lib/gcc/i686-apple-
darwin9/4.2.1/libgcc_s.1.dylib (compatibility version 1.0.0, current
version 1.0.0)
}}}
you can notice libpolybori/libpolybori.dylib on its lonesome.
