Re: octave forge question

[Tatsuro MATSUOKA]

Hello Doug

If you have a error pkg install, please execute first

pkg install -verbose optiminterp-0.2.5.tar.gz

to see the errors in detail.
Sometimes this not enough, at that time extract xxxx.tar.gz file and
go to the directry xxxxx and then ./configure and make.
More detailed information will be obtained about errors.

However in this case your information is enough.
The optiminterp package requires the complification of F90 files.
If the gcc verion is 3.x.x, you cannot build the optiminterp package at the 
present state.
(In gcc ver. 4, the fortran complier is a gfortran which can treat f90 and f95.)

To see your log in detail,
> checking for F77_FUNC... yes
> checking for Fortran flag to compile .F90 files... unknown

> checking for Fortran flag to compile .F90 files... unknown
is the origin of your error.

There is f90toC. 
http://www.ncsa.uiuc.edu/~mdewing/f90toC/

I tried the f90toC but my trial has not been successful yet.
I did the above trial on cygwin.

The other possibities is you to use the gcc-4.2.x.
In the cygwin case the  octave built by gcc-4.2.x have never run by seg-faults.
So at the moment I abandan to support the optiminterp pacake in my octave 
binaries on cygwin.

But your system, you might be suffessful for octave building by gcc-4.2.xx.
In the case, you may build optiminterp.

If you can get gcc 4.2.x binaries for your system,  you are lucky.
Otherwise you have to build the gcc-4.2.x (gcc-core, g++, gfortran) by yourself.
Please use the google to search building information.

In my case, I builded the gcc 4.2.x on cygwin by myself.
It is now used for the CVS version of the gnuplot building.

Tatsuro
