volk @1.1.1 fails to build with gcc-4.2

[semaphore45@…]

I tried to run

sudo port upgrade volk

manually after seeing it fail as part of another port's upgrade (gnuradio). It fails to build, and the first error logged in main.log is:

:info:build /opt/local/var/macports/build/_opt_local_var_macports_sources_distfiles.macports.org_ports_science_volk/volk/work/volk-1.1.1/include/volk/volk_common.h:71:23: error: x86intrin.h: No such file or directory

Ran on Mac OS X 10.6.8 aKa Snow Leopard with XCode 3.2.6. Joined is the full main.log

This problem was discovered as I needed to install openSSH to access a Synology's NAS SSH shell.

This port upgrade was attempted after performing

sudo port upgrade readline

to correct issue mentioned in ProblemHotlist#ncurses6

x86intrin.h was added in gcc 4.5, and is just a wrapper that includes all of the headers for the intrinsics associated with the various x86 instruction set extensions. A possible workaround would be to instead include one of the more specific headers that did exist in 4.2, like xmmintrin.h.

I have a similar problem on 10.7.5. Have tried using macports gcc and clang, still no joy. if it's a header issue…where might i find some guidance on how to use a different set?

This should now be fixed by ​https://github.com/macports/macports/ports/commit/46202f98147d9ce8a72e831416b3203178c31fb3 . Please update your ports and hopefully Volk now works. Installing Volk on certain older OSX will now require installing a MacPorts Clang compiler, which will take a bit more time ... but, it should now work!

I'm going to close out this issue as fixed. Please reopen if that's not the case and provide a new build log.
