Re: [Mingw-users] MinGW for Windows 7 64 bit

[Craig P. <CP...@wo...>]

Thanks again for the advice,

I think you have got to the crux of the issue. Presently it is not a problem with MinGW but the other components. I have corresponded with Geoscience to see what they think is causing the lapack_lite error.

So I will see if I can get past those issues and get back to you if it becomes a MinGW problem, or if I am successful in utilising MinGW 64 bit in this environment.

Hi Craig -

It doesn't look like this particular part of the build process has anything to do with mingw -- so the mingw list won't be able to help much with your current issue.

Is there a Numpy mailing list that could help with this part of the build process?

It looks like Numpy is looking for a lapack_lite library (maybe -- just guessing -- a file called something like lapack_lite.dll).

I don't see anything yet that looks like it involves mingw.

I would expect that you would get this far in the build procedure, and have the same error message, even if mingw weren't installed at all.

Indications that mingw might be involved would be an error message coming from gcc (the compiler that mingw provides), or an error message about a line in a file written in the C language.  (Hypothetically, maybe mingw's gcc will be used to compile "anuga.c".)  Or an error message that says something like "mingw_xyz.dll not found."

Since you're working with a package that has lots of pieces from different places, you might need to get help from different places.  Until you hit a problem related to mingw, there's not much advice we can offer you here.

(From what I can deduce, it looks like this ANUGA stuff is largely python stuff, with mingw playing a minor role.  But I still have no idea how mingw is used by ANUGA.)

Good luck.
