Portable cpu_target on Windows #47

Open joaquimg opened 6 years ago

joaquimg commented 6 years ago

I have successfully compiled all my programs and used them in my computer (windows 10). But I am having portability issues.

When I compile on my "windows 10 64bits core i7-5500U" with cpu_target="core2" it works on all other i7 I could test on. However, when I use that on an amazon "Windows Server2012-R2 with Intel Xeon E5-2670 v2" I get the following error:

LLVM ERROR: Program used external function 'rint' which could not be resolved!

rint seems to be from openlibm.

If I compile on the amazon windows server with cpu_target="native" everything works smoothly. However, I could not compile it with no other cpu_target, I tried: core2, i686, generic, i386 .

Any Ideas? Which cpu_target is used for the julia distribution?

Note that the same julia distribution (0.5.1 64bits) works perfectly on all the machines mentioned here, I copied and pasted the whole folder to confirm.
