That's about as far as I've got

I've just now managed to get ICC-Support-Lapack-0.6 and ICC-Support-Levmar-0.50 to build ok and pass the test suite on Strawberry-5.28.0.
With the 'Levmar' module, the following command gets run at the end of the 'perl Build':

g++.exe -o "blib\arch\auto\ICC\Support\Levmar\Levmar.xs.dll" -Wl,--ima
+ge-base,0x2d170000 -mdll -s -L"C:\_64\strawberry-5.28.0\perl\lib\CORE
+" -L"C:\_64\strawberry-5.28.0\c\lib"
 "lib\ICC\Support\Levmar.lds" -framework Accelerate "lib\ICC\Support\L
+evmar.exp"
[download]

That command fails in the way I outlined earlier. But if I remove the last 4 arguments and manually run:

g++.exe -o "blib\arch\auto\ICC\Support\Levmar\Levmar.xs.dll" -Wl,--ima
+ge-base,0x2d170000 -mdll -s -L"C:\_64\strawberry-5.28.0\perl\lib\CORE
+" -L"C:\_64\strawberry-5.28.0\c\lib"
[download]

then the build is completed, and I can then successfully run 'perl Build test'.

And it's the same for the 'Lapack' module (except, of course, that occurrences of "Levmar" are replaced by "Lapack").

However, manually running edited commands is not an ideal way to complete a build.
It would be better if Module::Build could be coerced into producing the shortened command that actually works.
I don't know how to get Module::Build to do that. Someone other than me would have to sort that out.

Cheers,
