For building 64-bit on Solaris, I use small shell script wrappers to
help ensure that correct options are passed. For example, this is the
text of a script called c++-64:
#!/bin/sh
exec c++ -m64 -march=opteron "$@"
I then specify CXX=c++-64 to the configure script.
In order to make building configure-based packages fairly easy, I use
a separate install tree for 64-bit apps (e.g. /usr/local64) and then
add a share/config.site script under that tree similar to the one
attached. The configure script automatically sources the config.site
file, which supplies default options. The advantage of this approach
is that selection of a 64-bit build may be specified by the --prefix
option to the configure script and then the configure script
automatically uses the right options and everything just works. So
one install prefix is used for 32-bit apps and another is used for
64-bit apps.
Last I heard, Solaris was being dropped from OpenEXR's "supported"
list. Hopefully someone will have the sense to add it back.
