in gnustep-back I am trying to compileagainst the cairo library both on solaris

I strongly suggest fixing the .pc file.
the .pc file from cairo? this wizardry is hard to fix ...
I see no linkage to tls!

So libpixman-1.so needs the symbol, but does not link against it.
__tls_get_addr is not
from GnuTLS (Transport Layer Security), but from a multithreading library
(Thread Local Store).
I don’t know where this comes from, 1 minute Googling didn’t bring up anything
reasonable
and I can’t remember to have seen this before. You may need to investigate.
thanks for the TLS poiter and the -r flag, it is thus a lazy symbol.
I tried to rebuild pixman (without any update) and I notice that the
work/solaris9-sparc/build-isa-sparcv9/pixman-0.22.2/pixman/.libs/libpixman-1.so
already has that issue. I then changed the receipe to build with GCC
instead of sun studio, but no fix.
This is ldd -r on Solaris sparc 10

I notice there is an extra "dl" library!
Darn. I found of several people who have a similarproblem, but
absolutely no solution. some peoplce cited the -z linker flag, but it
needs an option which I don't know which is correct.
