I wanted to report some things I ran into while building the mpir-2.7.0-alpha4.
I am building on Windows XP x64 (old OS, I know) in an MSYS shell using the
MinGW64 compiler.
./configure --enable-gmpcompat --enable-cxx --disable-static
make
make check
This configure and make both succeeded for me. However, I ran into a known
problem (on WinXP) during "make check" with t-printf. So, nothing new here, and
I would call it an overall success. However, this configure is not how I
normally make MPIR, so (after deleting and recreating the folder) I then did:
./configure --enable-gmpcompat
This configured for a few seconds, and then complained with:
configure: error: cannot build both static and DLL, since mpir.h is different
for each.
Use "--disable-static --enable-shared" to build just a DLL.
I only wanted a static build. I thought this used to be the default
interpretation of the configure line I gave, but perhaps not. So, then I added
--disable-shared to get:
./configure --enable-gmpcompat --disable-shared
make
make check
This configure and make both completed successfully for me. This "make check"
also ran into the known (on WinXP) problem with t-printf. All other tests
passed, so I would call this one good too.
Then I tried to compile the latest svn version of gmp-ecm with this MPIR 2.7.0a4
gmp.h and libgmp.a. I ran into problems and I'm wondering if it is an issue
with the MPIR functions, or the way gmp-ecm is calling these functions. The
error I got was:
--------------------------------------------------------------
mpmod.c:1503:7: error: too many arguments to function '__gmpn_mulmod_Bexpp1'
PTR(R)[n] = mpn_mul_fft (PTR(R), n, s1p, ABS(s1s), s2p, ABS(s2s), k);

Actually, now that I look at old versions of both MPIR and gmp-ecm, I don't see
any changes to this function call. It doesn't look like this function was in
MPIR 2.5.2 and it looks like the function is the same between 2.6.0 and 2.7.0.
So this is most likely a problem with the gmp-ecm source. I'll let them know
about this issue.
So, all that to say, the latest 2.7.0-alpha4 seems to be working just fine for
me. Thanks!
