xlintstz failure in mingw64

Postby silent_missile » Sat Feb 26, 2011 9:30 am

Hello, for some reason I have to use win7 x64 in my work, so I tried mingw64 to compile lapack, but I fail at xlintstz step for complex 16 linear equation

My test platform: AMD5000+ x64, 2G ram, win7 x64, msys, tdm-mingw64-4.5.1, VC 2008 Express

My test software: gotoblas2-1.13, lapack-3.3.0

I started the command line from VC command prompt, and started msys from that prompt, so the tools in VC and msys can all be used.

First I compiled gotoblas2-1.13, and it seemed to be all right, libgoto2_opteronp-r1.13.lib, libgoto2.dll and libgoto2.lib are generated.

Then I put libgoto2_opteronp-r1.13.lib to lapack root directory, and modify make.inc in lapack directory

Code: Select all
PLAT = _mingw64
FORTRAN  = gfortran -fimplicit-none
OPTS     = -O2 -m64 -mmmx -msse -msse2 -msse3
NOOPT    = -g -O0
LOADER   = gfortran
LOADOPTS = -O2 -m64 -mmmx -msse -msse2 -msse3
BLASLIB      = ../../libgoto2_opteronp-r1.13.lib

Then I typed mingw32-make in the console, and lapack_mingw64.a was generated successfully, then test started automatically, but xlintstz run error, then an error dialog appear and it told me xlintstz.exe run in error, when I close the error, the following tip appear in the console

Code: Select all
Testing COMPLEX16 linear equation routine
./xlintstz < ztest.in > ztest.out 2>&1
make[1] *** error 38

When I compiled it by mingw32 for 32bit binary, every step went well, and I tested the generated lapack and libgoto by armadillo, they worked well. But I can't pass test during mingw64 compiling, I dare not to use the lapack_mingw64.a for my work, because I don't know when it can be wrong.

Can anyone help me to resolve this problem? 32 bit precision is not enough for my work, I need 64 bit binary files for windows, and I don't have any commercial compiler, gfortran is the only choice for me.

you should try to add the -m64 flag in NOOPT.

thanks Julie, I tried your suggestion, I added -m64 for NOOPT, but the error occur again, and the hint is the same

If I use reference blas within lapack source pack, I can get win64 binary, but it's much slower, nearly 1/18 speed, I need gotoblas to replace reference blas
