[GiNaC-list] Ginac mingw build cannot go well

[tmacchant4 at yahoo.co.jp]

Dear all

My name is Tatsuro MATSUOKA.  I am a Octave-cygwin maintainer  and
also am trying to build octave system on the mingw.

http://www.geocities.jp/tmoctwin/

I am struggling with Octave-forge packages on mingw. The Octave-forge
packages, which are additional packages to Octave, have a symbolic
package, which are mainly for used for get analytical derivatives for
non-linear eq. and ODE solvers.

Unlike the cygwin, the building process of GiNac is very difficult for
me and has not been successful yet. (Cygwin build was easily
successful)  With the help of the cygwin pkg-config and fig2dev, I
have at last been successful in ./configure.  However I have not been
successful for the 'make'.
Error messages at the 'make' are described at the end of the mail.

   excompiler.cpp:116: error: `mktemp' was not declared in this scope

This error might be critical and I have not been able to find the reason.

I would like to wait for someone suggesting me.

Regards

Tatsuro
