<div dir="ltr">Hi,<div>I'm not sure if I should submit a bug report about this or not, but there are two issues with building distributable binaries with the Intel compilers on Mac OS X.</div><div><br></div><div><div><ol>
<li>I think that '-Wl,-macosx_version_min,${CMAKE_OSX_DEPLOYMENT_TARGET}' should be added to all the linker flags. Without this, using Unix Makefiles as the generator, this flag doesn't get passed to the linker and as a result the executable only runs on systems with the same OS as the executable was built on. (Possibly newer OSes too, but I haven't tested this.) If I build a binary on 10.8 and try to run it on my wife's computer without passing this flag, even though CMAKE_OSX_DEPLOYMENT_TARGET is set to 10.6, I get the following error: 'Illegal instruction: 4' I have no idea whether this issue applies to the XCode generator as well. See <a href="http://software.intel.com/en-us/articles/running-an-intel-compiled-binary-on-older-mac-os-x-system-gives-dyld-unknown-required-load">http://software.intel.com/en-us/articles/running-an-intel-compiled-binary-on-older-mac-os-x-system-gives-dyld-unknown-required-load</a></li>
<li>While ifort, icc and icpc provide -arch=i386 and -arch=x86_64 compatibility options (for compatibility with GCC) the prefered flags are -m 32 and -m 64 respectively. Furthermore, CMake tries to pass all the architecture flags at once to the compilers, whereas to build a universal binary with the Intel compilers one must first build the intel 64 and intel 32 versions separately and then combine them with the lipo tool.
