Compiling freeware for SGI

Unread postby shrek » Sat Jun 07, 2003 10:16 am

Hi,

I was just setting up my webserver and needed GD support under Perl. Because the default Perl installtion of SGI is quite old I choose to use freeware version. But instead of the normal perl I used perl64.

perl64 -MCPAN -e shell
got me nicely into the CPAN shell and install GD worked but asked me for the path of the GD libraries (2.0.12 or higher)
Okay I thought, lets see what freeware.sgi.com has to offer me... nothing but old versions :(
Then I downloaded the soruce package and did a ./configure && make && make install (used prefix /usr/freeware)
But that wasn't good enough for Perl because Perl was going to build GD 64 bit but with my configure steps I made a 32 bit version :(
After some "hacking" of the Makefile and the libtool file I got it so far to compile for 64-bit.
And here comes the question:
Is there in general something I can use to force my freeware to be build in 64-bit without hacking the Makefiles?

Futhermore I would be interested in some hints on how to make a tardist of this package that I can easily give to people in interest of a binary of GD-2.15 (and in future other products)
Now I also see that the packages of Freeware.sgi.com are both 32-bit and 64-bit. Any info on how to accompilish that for this package?

Um, for building 64 bit freeware stuff, try compiling with:

setenv CFLAGS '-I/usr/freeware/include -L/usr/freeware/lib64 -mips4 -64'
and CXXFLAGS appropiately. Good configure/Makefile files detect this and incorporate this into the config.h before making your executable.

BTW, compiling 64-bit can slow down program execution a bit. I noticed this on some of my older fortran programs. So definately test -n32 and -64 before you commit yourself to 64 bit.

Personally, i wouldn't recommend -64 unless the addressing space you need is more than 4 gigabyte, like coding parallel applications with MPI. I had compiled an MPI-program on the 1024 Origin3800 in Amsterdam, but forgot the -64 option. Suddenly, all my runs with cpucount higher than 8 would complain that it couldn't find /dev/zero ....

For making tardists, please read the man page of swpkg and accompanying documentation in the Insight book library, installed on your SGI box.

Also, for freeware you should use gmake(not make), and if you get problems with ranlib, set ranlib=:. SGI has some good info on building freeware on their freeware.sgi.com site. Definatly good to look over.
