libiomp5.dylib needed even though I link statically

Mikael_Grev — Sat, 22 Aug 2009 22:04:40 GMT

Hello, Maybe I have misunderstood this in some way but I'm trying to link without any dunamic libs. I statically link to libiomp5.a but still it wants the .dylib when I run the app.

I use OpenMP.

Any suggestions how I can break the dependency on libiomp5.dylib?

Cheers,

Btw. Got 67ms jpeg encode+decode on a 2560x1600/32 image. Darn that's fast!! MacBook Pro Dual Core 2.

Oh yeah. Almost forgot.

I'm on a Mac OS X 10.5.7 using Compiler 11.1/058

You post, you solve. :)

Intel Compiler Runtime needs to be set to static under "Build" in XCode.

Hi Mikael,

Thank you for sharing. Yeah, when enable OPENMP, Intel Compiler will link libiomp5 dynamic by default.The openmp library used by IPP is also from Intel Compiler. So we need take care when use them.
