Hello Herbert,
I'm sorry to bother you, but recent GHC HEAD does have issue on
Solaris/SPARC platform which shows as undefined symbols during the
linkage of stage2 binaries. For example ghc-stage2 link step fails with:
Undefined first referenced
symbol in file
__gmpn_andn_n
/home/karel/src/ghc-sparc-reg_ncg-head-2015-01-17/libraries/integer-gmp2/dist-install/build/libHSinteg_21cuTlnn00eFNd4GMrxOMi.a(Type.o)

ld: fatal: symbol referencing errors. No output written to
ghc/stage2/build/tmp/ghc-stage2
All binaries fail with the same set of unresolved symbols. I can tell
you that I don't see this issue on Solaris/i386 nor on Solaris/amd64
builds as you can verify here: http://haskell.inf.elte.hu/builders/
I'm talking here about exact Solaris 11.1 on SPARC and Solaris 11.1 on
AMD64 box. Both Solarises provide the same version of libgmp:
$ uname -p
sparc
$ ls -la /usr/lib/libgmp.so*
lrwxrwxrwx 1 root root 15 Feb 20 1999 /usr/lib/libgmp.so
-> libgmp.so.3.5.2
lrwxrwxrwx 1 root root 15 Feb 20 1999
/usr/lib/libgmp.so.3 -> libgmp.so.3.5.2
-r-xr-xr-x 1 root bin 1093328 Sep 19 2012
/usr/lib/libgmp.so.3.5.2
$
$ uname -p
i386
$ ls -la /usr/lib/libgmp.so*
lrwxrwxrwx 1 root root 15 Oct 18 2012 /usr/lib/libgmp.so
-> libgmp.so.3.5.2
lrwxrwxrwx 1 root root 15 Oct 18 2012
/usr/lib/libgmp.so.3 -> libgmp.so.3.5.2
-r-xr-xr-x 1 root bin 878276 Feb 5 2014
/usr/lib/libgmp.so.3.5.2
$
And yet on i386/amd64 the symbol (one from the failing set as an
example) __gmpn_andn_n is defined:
$ nm /usr/lib/libgmp.so|grep __gmpn_andn_n
[86] | 375728| 101|FUNC |GLOB |0 |14 |__gmpn_andn_n
but on SPARC it's not:
$ nm /usr/lib/libgmp.so|grep __gmpn_andn_n
$
Do you have any magical knob which I can switch on to work around this
issue by not needing those four symbols above?
Thanks!
Karel
