Re: Compiling 2.1.71 on FC4

[Shai Ayal]

Quentin,

what options to configure did you use when compiling octave for FC4?

I tried using gfortran as follows and it did not pass the tests:
F77=gfortran ./configure --enable-shared --disable-static
this compiles using gcc,g++ & gfortran which are all version 4.0.1
It hangs on trying to do:
cond ([1, 2; 2, 1])
from the octave.test/linalg/cond-1.m test.

The version I did manage to compile and is working is:
CC=gcc32 CXX=g++32 ./configure --enable-shared --disable-static
that is, using the 3.2 versions of gcc,g++ and g77

Shai

p.s. Disclaimer: As I mentioned this is not a plain vanilla FC4, but an 
upgraded FC1 with a lot of historical stuff lying around which could be 
causing problems.
