[MLton-user] mlton-20070826 on mingw

[Bernard Berthomieu]

Hello,

So far, we were building our mlton applications for windows using a 
cross-compiler,
based on mlton-2005. We want to upgrade to mlton-2007; since a prebuilt 
-20070826
for mingw is available, we gave it a try, using the latest msys 1.0 and 
mingw 5.1.3,
and the prebuilt dynamic libgmp from http://cs.nyu.edu/exact/core/gmp.

We could successfully compile our applications, and they run correctly 
with libgmp
dynamically linked. However, for compiling, we had to remove the 
declarations of
timezone and gettimeofday from file 
<mltondir>/lib/mlton/include/platform/mingw.h
as  these are now provided by the current mingw headers and gcc 
complained for
the redeclarations.

Now, to ease installation of our applications,  I typically install 
mlton so that libgmp
is statically linked with the applications, by putting a copy of 
libgmp.a into
lib/mlton/self. I have seen in previous messages on this list that this 
does not work
for mlton-20070826 on mingw. If I'm doing this, I get the link error:

      <mltondir>\lib\mlton\self/libmlton.a(gc.o):gc.c:(.text+0x2ec5): 
undefined reference to `_imp____gmpz_cmp'
      <mltondir>\lib\mlton\self/libmlton.a(gc.o):gc.c:(.text+0x4289): 
undefined reference to `_imp____gmpz_get_str'
      <mltondir> etc,

Could someone explain me why exactly do we get the above error ?
and how one could link libgmp statically with mlton applications on that 
platform.

Many thanks for any help,

  Bernard.
