On Windows, if I run 'make check' straight after configure (without first running 'make') I, too, get an error - though in my case the error I'm getting is that libgmp.la cannot be found. (This error is to be expected since libgmp.la, which gets built during the 'make' step, has not yet been created.) By running './configure' (without any additional arguments), you'll be building a dynamic (dll) gmp library and, for me, 'make check' is failing all tests with such builds. I don't know why that happens. Afaict, there's nothing wrong with the dll that gets built - the apps that I build using that dll always work as they should. I'd be interested to know if 'make check' succeeds for you (after you've run 'make'). The problem applies only to dynamic builds. If I build a static gmp library (by starting with './configure --disable-shared --enable-static') there's no problem with 'make check'. Cheers, Rob </blockquote> 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:\mysql++-3.0.3\include_lib_a_def\libmysqlclient.a E:\mysql++-3.0.3\include_lib_a_def\libmysqlpp.a E:\C++\codeblocks\libraries\libmapm.a E:\C++\codeblocks\libraries\gmp\msys\libgmp.a E:\C++\codeblocks\libraries\gmp\msys\libgmpxx.a E:\C++\codeblocks\libraries\gmp\msys\libcxx.a E:\C++\codeblocks\libraries\gmp\msys\libgmpxx.a(osmpz.o):osmpz.cc:(.text+0x39): undefined reference to `___gmpz_get_str' E:\C++\codeblocks\libraries\gmp\msys\libgmpxx.a(osdoprnti.o):osdoprnti.cc:(.text+0x9d): undefined reference to `___gmp_doprnt_integer' E:\C++\codeblocks\libraries\gmp\msys\libgmpxx.a(osdoprnti.o):osdoprnti.cc:(.text+0xa9): undefined reference to `___gmp_asprintf_final' E:\C++\codeblocks\libraries\gmp\msys\libgmpxx.a(osfuns.o):osfuns.cc:(.rdata+0x4): undefined reference to `___gmp_asprintf_memory' 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. </blockquote> Hello, -I think the dll was not created becase the libtool had undefined symbols, so it just made the static lib. -I saw the following from the GMP documentation "MINGW uses the C runtime library `<samp>msvcrt.dll</samp>' for I/O, so applications wanting to use the GMP I/O routines must be compiled with `<samp>cl /MD</samp>' to do the same. If one of the other C runtime library choices provided by MS C is desired then the suggestion is to use the GMP string functions and confine I/O to the application. " Could this be the reason for the undefined references?  If so how do I "complie with the `cl /MD`"?  Do I have to use ./configure CFLAGS=cl /MD?
