Le forum de XCAS

Hi,

Before I start asking.. let me write that I get the source from here:
https://www-fourier.ujf-grenoble.fr/~pa ... stable.tgz

This will be the latest stable with bugfixes I hope.

I have asked before how to compile with cygwin and I was greatly helped by Bernard. I am not sure if everything will work, but so far I could link to giac dll. Now, though, I want to move one step ahead and try to get independent of cygwin. So I tried using codeblocks with gcc. In windows alloca or alloca.h does not exist (I believe _alloca is defined but not recommended). Now, in the config there is an option called HAVE_ALLOCA and HAVE_ALLOCA_H. These two do not seem to affect the code. Thus, compiling (without cygwin) in windows will give the first error (after tweaking the config.h file)
Was there any purpose of having HAVE_ALLOCA in the config options? Is there a way to cleanly resolve this? Is this because I have an old version of the source code?

Jose

PS: Aside from the proper configuration for cygwin (see my last post here). To compile without cygwin I did the following additional changes to config.h:
- removed HAVE_LIBPNG, HAVE_SYS_TIMES_H, HAVE_LIBRT, HAVE_ALLOCA, HAVE_ALLOCA_H

alloca is not checked explicitely in configure.in, I guess it is automatically checked by the gnu configure tools.
Replacing alloca by malloc is not straightforward because it requires adding free. It's also slower. Perhaps the best is to #define alloca _alloca for your target, something like in first.h.
By the way, giac_stable.tgz links to the latest source used for the debian packages on my site. It is not fully up to date, but almost.
