Dear Jeff,
I enclose the config.log.
I also forwarded the problem to Sun support, and I got the following
advice from
Gunter Roeth <Gunter.Roeth_at_[hidden]>:
J'ai installe LAM sans probleme, mais il ne faut pas setter les LDFLAGS
et etre sur (pendant la configuration uniquement) que le PATH ne
contient
plus de possibilite de trouver un gcc. Les settings sont comme :
> setenv FC /opt/SUNWspro/bin/f90
> setenv FFLAGS "-fast -xarch=amd64"
> setenv CC /opt/SUNWspro/bin/cc
> setenv CFLAGS "-fast -xarch=amd64"
> setenv CXX /opt/SUNWspro/bin/CC
> setenv CXXFLAGS "-fast -xarch=amd64"
ou plus court :
setenv FC "/opt/SUNWspro/bin/f90 -xarch=amd64"
The advice was good, as I now have a fully functional LAM. However the
bug is still pending around !
I'll experiment the 7.1.2 beta but I not sure to have enough time before
catching my plane...
Pierre.
