I'm trying to compile the libvorbis library on a SGI octane 2, Irix 6.5... libogg compile directly, but I got this stange error when trying to compile libvorbis.

Here is the make output :

Thanks in advance for checking what it can be. If you need more information, just contact me and I'll try to get it for you....

BTW, I run both configure command with :

./configure --prefix=/home/houlem/bin/ --exec-prefix=/home/houlem/bin/
