Hi Stan,

Can it be that you were still using the "original" gtod.c? Because in my recent rsocket patch there was also contained an updated gtod.c with (among other things) gettimeofday() changed to static.
However, non-static gettimeofday() is just as well for me. But I recommend to at least adopt my real modification of gtod.c, in order to fix a potential division-by-zero issue when calling gettimeofday() from a multi-threaded process (see also ofw Digest, Vol 68, Issue 2 from Dec 17, 2012).

All your divide-by-zero mods are included.

The 'static' qualifier is IMHO is the incorrect attribute to be using; how many copies of gettimeofday() does an application need?
Not to mention the 'static' inhibits the detection of duplicate gtod.c includes.
It's truly sad that gettimeofday() is a '#include <etc/gtod.c>' and not in a library somewhere.
I'm convinced that for now, the 'static' qualifier should be removed and will do so.

Stan.

Thanks,
Hubert

Betreff: rsocket.c & gtod.c duplicate include error.
Hello,
  When building winOFED from trunk\ svn.3425 I find duplicate definitions of gettimeofday() link errors when building ulp\librdmacm?
Duplication is resultant from



ulp\librdmacm\src\cma_main.cpp:#include "../../../etc/user/gtod.c"

ulp\librdmacm\src\rsocket.cpp:#include "../../../etc/user/gtod.c"



Fixed by removing gtod.c include from rsocket.cpp
