[Mingw-users] troubles compiling the GNU GMP under MinWG

[Euchner, Martin]

Dear experts,

I'm facing troubles compiling the GNU GMP under MinWG and would like to hear which mailing list (mingw-***@lists.sourceforge.net<mailto:mingw-***@lists.sourceforge.net> or gmp-***@gmplib.org<mailto:gmp-***@gmplib.org>) is most appropriate to following-up with detailed questions?

In addition, I'm wondering if MinWG correctly figured out my CPU processor?

I have Windows 7 Enterprise OS running on Intel(r) Core(tm) i3-2330M CPU using 64-bit OS (that's what System reported).

My ENV reports:
PROCESSOR_IDENTIFIER=Intel64 Family 6 Model 42 Stepping 7, GenuineIntel
OS=Windows_NT
PROCESSOR_LEVEL=6
PROCESSOR_ARCHITEW6432=AMD64
PROCESSOR_ARCHITECTURE=x86
MSYSTEM=MINGW32
PROCESSOR_REVISION=2a07
NUMBER_OF_PROCESSORS=4

gcc is compiling using -mtune=sandybridge -march=sandybridge

This is setting correct?

With kind regards

Martin Euchner.

It depends on what problems are you having. So it's hard to answer
that with only the information you provided.

Dear Eli,

Thanks, and sorry for the too big attachment. I removed the compile log of GMP; here's where I got stuck with compiling the GMP demos:

Do you have any idea what needs to be changed to get the demos executable?

The GCC command line obviously lacks the reference to GMP library. I
would look at the Makefile which produced this command, probably some
variable isn't set there correctly or has an empty value.

Did the library itself build successfully?

Dear Eli,

Many thanks for the hint.
Indeed, when I manually -lgmp then all works fine:
gcc -m32 -O2 -pedantic -fomit-frame-pointer -mtune=sandybridge -march=sandybridge factorize.c -o factorize -lgmp

The -lgmp must be after the .c (or at the very end) but I did not manage to fix the Makefile accordingly. I'm not enough Makefile expert to get this fixed, and I leave to somebody else to fix that in the package.

Here's the stripped-down Makefile to be fixed:
CC = gcc
CFLAGS = -m32 -O2 -pedantic -fomit-frame-pointer -mtune=sandybridge -march=sandybridge


Anyway, many thanks for your help!

Regards,

Martin.

CFLAGS is not the whole story. There should also be LDFLAGS or LIBES
or something like that, which is specifically used on the link (as
opposed to compilation) command lines.

$ cd demos

Try "make factorize.exe" instead of "make factorize" and see if that works.
