RE: Problems building Octave on Solaris 2.9 with gcc-3.4.2 and f2c

[Mulley, Nikhil]

I suggest to use the combination of Sun studio provided fortran and the gcc, I guess that should address your concern.

Subject: Problems building Octave on Solaris 2.9 with gcc-3.4.2 and f2c

Dear Octave Users

I am trying to build Octave-2.1.73 under Sun Solaris 9 using gcc-3.4.2 and f2c (as we don't have a Fortran compiler installed).  I build the components as "shared" as I wish to use Octave-forge.  The build fails due to causes related to f2c, generating this (edited) error message :

Undefined                        first referenced
 symbol                              in file
MAIN__                              <path-to>/local/lib/libf2c.so
ld: fatal: Symbol referencing errors. No output written to octave
collect2: ld returned 1 exit status

Despite specifying the path to the directory where libf2c.so resides, I had to edit the generated Makeconf file and add "-lf2c" to the  LIBS variable.  "f2c" itself is found OK.  It seems the autoconfig process might need some tuning.  For "configure", I use "--enable-shared --disable-static --with-f2c LDFLAGS="-L<path-to>/local/lib -R<path-to>/local/lib" .  I do not have any old versions of Octave installed.

I have built "f2c" and "libf2c.a/libf2c.so".  Here is some output of "nm <path-to>/local/lib/libf2c.so", just in case this means something to someone :

[622]        |     17736|     292|FUNC |GLOB |0    |7      |main
[25]        |         0|       0|FILE |LOCL |0    |ABS    |main.c
[24]        |         0|       0|FILE |LOCL |0    |ABS    |main.xxx
[858]        |         0|       0|NOTY |GLOB |0    |UNDEF  |MAIN__

[774]        |         0|       0|NOTY |GLOB |0    |UNDEF  |memcpy

From stuff on the Web, I gather that the MAIN__  is something to do with building f2c as shared.

I have also tried building Octave-2.9.6 but that fails with

I cannot find where "log2" and "exp2" are defined/declared.

Any hints on how to build Octave on Solaris 2.9 would be welcome.  I want to use Octave and Octave-forge to do some Empirical Mode Decomposition (Intrinsic Mode Function) analysis using Rilling's "emd.m" .

Thanks,
