How to make your own optimized Seti@Home client for Linux

ICC is a frustrating compiler >:(
Your executable is static, my dynamic.
The -static flag cause me headache:
checking size of long int... configure: error: cannot compute sizeof (long int), 77

Mmm...if I remove all -Wl,-Bdynamic it compile fine and static...
Now I think:
It's configure that insert in Makefiles this linker option,
why?
Is it wrong? Or is it's a ICC bug that should ignore it in a static compile?
Boh...
Maybe that removing this option from all Makefiles static compile works, but it's dirty.
I hope that this can be of useful.
Simon:
Thanks for the hint, I'll try that next time I compile on Linux.
I've long been annoyed that I couldn't compile a real static binary as-is, and agree it's most probably a configure problem (I don't think -static worked as is with GCC either, though I'm not sure).
The real solution would be to modify configure.ac and change the macros there, I believe.
Regards,
Simon.

Support for these was added in the 5.1.1 IPP version and the 9.1.028+ ICC one.
HTH,
Simon.
P.S.: I know the 1.3 code isn't that quick on Core 2s - guess why I put the 1.41 up instead? ;)

Regarding 1.41 for Linux -- could you please make it so I can see the pre-released forum/downloads? I am not a builder (besides I use CentOS which is prohibitive to building Boinc), but I can test stuff. I've worked with Harold in the past.
Regarding -xT flag -- -xP also includes SSE3 instructions, but runs on single core EM64T Xeons. Most of my computers have these processors. You no longer have -xP Linux application, so I use -xN version. I've heard that benchmarks are pretty much the same on -xP and -xN versions.
Regarding -xW –axT flag -- that's not -xT -axT. It sounds like the code with -xW -axT flags should run on SSE3 Opterons and Athlon64s. Unfortunately, I no longer have one of these.

I think so, too.
I have done some tests:
I tried to manually link only seti_boinc with -static or to add -static to Makefiles removing any -Wl,-Bdynamic.
It produce these errors:

Adding -lirc it seems to compile fine and static, I have not yet tested it.
However IPO warnings remain and it seems to depend on glibc version used to compile :-[
Maybe some source modification are needed...

Simon:
Good work!
I'll try and incorporate this into the How-To and get the next versions compiled as fully static binaries.
Thanks for your help!
Simon.
