flint always building 32-bit on Solaris even when SAGE64="yes"

[sagetrac-drkirkby]

Using

• A Sun Blade 2000 running Solaris 10 update 7
• Sage 4.1.2.rc0
• gcc 4.4.1
• SAGE64 exported to "yes"

Looking at the directory $SAGE_HOME/local/lib, we can see the flint library is 32-bit, even though SAGE64 was set to "yes", so flint is ignoring the setting of SAGE64. It should also be notes that flint ignores CC and CXX too - see #7024

This is far from the only package building 32-bit when SAGE64 is set to "yes" on Solaris. All of the following do, and I suspect there are many others too.

• zlib zlib-1.2.3.p4 always builds 32-bit binaries on Solaris. #7128
• libgpg_error libgpg_error-1.6.p2 always builds 32-bit binaries on Solaris. #7129
• libpng libpng 1.2.35 always builds 32-bit libraries on Solaris. #7130
• libcliquer libcliquer always builds 32-bit libraries on Solaris. #7131
• pari pari-2.3.3 always builds 32-bit libraries on Solaris. #7133
• ntl ntl 5.4.2.p9 always builds 32-bit libraries on Solaris. #7134
• python python always building 32-bit on Solaris #7135
• gp gp always building 32-bit on Solaris #7136
• ratpoints ratpoints always building 32-bit on Solaris even when SAGE64="yes" #7137
• freetype freetype always builds 32-bit libraries on Solaris, even when SAGE64="yes" #7138

mpir currently mixes 32 and 64-bit objects, so does not build at all #7132.

I will sort this package out after creating a new sage-env, which exports all the variables properly, including the flag for building 64-bit code, which is not always -m64.

Although there is no support for AIX or HP-UX in Sage yet, we could potentially add it - I personally own machines running AIX and HP-UX.

IBM's compiler on AIX uses -q64, and HP's on HP-UX uses +DD64.

The sensible way to resolve this is to add the correct flag on every platform. This is not a very difficult task really. Whilst any changes to the source that might be necessary for a port would take a lot of time, finding the right flags to build with should be quite easy.

Like an idiot, I created another ticket for this same problem. I'm closing this one, as the other one has the patch and is more upto date.
