Description icepic 2002-07-02 13:26:59 UTC 
I have tried to read the include-files over and over, and can't grasp why
CLK_TCK isn't defined. Also, the fix in the later versions (according to the
web-cvs) tries to use _SC_CLK_TCK, but this isn't picked up either.
(I doing this on RedHat7.2-x86 gcc3.04)

Since time.h in some cases declared CLK_TCK as CLOCKS_PER_SEC (as used later on
in ttime.cxx) I've replaced CLK_TCK with CLOCKS_PER_SEC and then it compiles, but
I don't really know if that is ok.
Since the machine is rather stock RH-install, I can't see how it never was an
issue for anyone before?
Comment 1 icepic 2002-07-02 13:48:38 UTC 
Well, it doesnt lack the definition, it just never gets defined.
The string CLK_TCK is in time.h of course, but the #ifdef's seems to
get it unparsed.
Quote:
/* This is the obsolete POSIX.1-1988 name for the same constant.  */
# if !defined __STRICT_ANSI__ && !defined __USE_XOPEN2K
#  ifndef CLK_TCK
#   define CLK_TCK	CLOCKS_PER_SEC
#  endif
# endif

Actually the OOo build requirements for Linux are gcc 3.02 or gcc
2.95.2 as mentioned on 

http://www.openoffice.org/dev_docs/source/build_linux.html#BuildRequirements

With that compiler the time.h CLK_TCK is defined if
!defined(__STRICT_ANSI) || defined(__USE_POSIX).
Comment 3 icepic 2002-07-02 16:06:02 UTC 
Now there, I've built gcc3.0.2 and restarted a fresh compile of
OOo. Same error.
Somehow, I didn't think the gcc folks would change to/from
__STRICT_ANSI__ or __USE_XOPEN2K overnight going form 3.0.2 to 3.0.4.

hro@hjs: Can please tell how to workaround this problem. Guess this 
is a know issue. I didn't found the thread in porting.dev you 
mentioned.
