Hi,
Has libtool been ported to Blue Gene/Q?
it has been ported to BG/L in 2009, search ChangeLog for BlueGene. This
port detects bgxl*, bgf*, mpixl* compilers and works for me on BG/P and
BG/Q. I explicitly force static linking and set the compilers like, e.g.:
--disable-shared --enable-static CXX=mpixlcxx_r F77=mpixlf77_r ...

HTH,

I have had trouble getting it to behave properly and have had to resort
to hacking it. Some of the issues include:
- It is trying to link in shared libraries, even though --enable-static
--disable-shared has been specified in autoconf
- Libtools all-static mode is linking libraries in multiple times, e.g.
<library1> <library2> <library1> <library1>, which is problematic,
because it leads to multiply defined symbols.
