Comment:
Thanks for the testcase! What is the correct output, and what output do
you get but not expect?
With atlas321_WinNT_PII.zip from
http://www.netlib.org/atlas/archives/windows/ I get:
{{{
$ ghc --make Test2.hs ctest2.c -lcblas -latlas -threaded -O -fffi
-Latlas/WinNT_PII/
Linking Test2.exe ...
$ ./Test2
"rounded base = 0"
C[0] = 2
C[1] = 2
C[2] = 2
C[3] = 2
}}}
which I assume is correct, and with your atlas.dll I get:
{{{
$ dlltool.exe -D atlas.dll -l atlas.lib
$ ghc -threaded -O -fffi --make Test2.hs ctest2.c -o Test2.exe -optl-
latlas -optl-L"."
[1 of 1] Compiling Main ( Test2.hs, Test2.o )
Linking Test2.exe ...
$ ./Test2
$
}}}
which looks broken, but in a different way than you were expecting?
