Hello,
I decided to reinstall msys and start again.
Details:
-Windows XP SP2
-I have MinGW (gcc version 3.4.5 (mingw-vista special)) at
C:\Program Files\CodeBlocks\MinGW\
-I have MSYS 1.0.10 at
C:\msys\1.0\
-In C:\msys\1.0\etc\fstab i have the following mount setting:
"c:/progra~1/codeblocks/mingw /mingw"
-I have unzipped GMP 4.2.2 to
C:\msys\1.0\home\dan\gmp-4.2.2

======PART 1 BUILD ===========
[note: the msys make is 3.79.1 built for i686-pc-msys , whereas the 
mingw32-make is GNU Make 3.81 built for i386-pc-mingw32]

my commands (with the new setup as described above) (output of these 
commands are attached in the .zip)
./configure --enable-cxx
make
make check

When I build this I do not get any DLL files, even though I do not 
provide the '--disable-shared --enable-static' switches.  Please explain?
During the make I receive the following warnings which i think are 
related to PART 2 of this email.

libtool: link: warning: undefined symbols not allowed in 
athlon-pc-mingw32 shared libraries
libtool: link: warning: undefined symbols not allowed in 
athlon-pc-mingw32 shared libraries

make check seemed to pass.

======PART 2 Linking Libary Issues===========

Now, I am trying to use the library that i just built.

Here is the simple code
#include <gmpxx.h>
using namespace std;
int main() {
mpz_class a;
a = 1234;
cout << a << endl;
return 0;
}

Here is the output from the build log
-------------- Build: Debug in stringmath ---------------

mingw32-g++.exe  -o bin\Debug\stringmath.exe obj\Debug\main.o 
obj\Debug\files\sint.o

E:\C++\codeblocks\libraries\gmp\msys\libgmpxx.a(osfuns.o):osfuns.cc:(.rdata+0x8): 
undefined reference to `___gmp_asprintf_reps'

I do not receive the undefined reference errors when I comment out the 
cout line.

After doing some reading online, I think (I could be absolutely off the 
mark though) these link errors have to do with the make procedure using 
the cygwin c++ runtime libraries instead of mingw32 c++ runtime 
libraries.  (I do not have cygwin installed, just the msys).  I think 
this has to do with the -mno-cygwin switch during the make process above.

The output from the configure/make/make check commands are attached.

How do I resolve these undefined reference errors.  Thanks.

Thanks for walking/talking through this with me.
