compile problem in simthread.cc

[Dwachs]

Nightly server has troubles to compile simthread.cc. See the log-files:

http://simutrans-germany.com/stn/data/compile.log.macpowerpc.txt
http://simutrans-germany.com/stn/data/compile.log.gcc3.txt

Dont know how to fix.

makefile needs to exclude simthread.cc when not MULTI_THREAD.

Or just wrap the entire file with an #if MULTI_THREAD>1, which is uglier, but perhaps more friendly towards IDEs.

On my system the check

Code Select Expand


#if _POSIX_BARRIERS>0

does not work: the hand-written barriers get compiled although  _POSIX_BARRIERS is defined by

Code Select Expand


#define _POSIX_BARRIERS 200809L

I cannot get this check to work properly

[TurfIt]

I've seen:

Code Select Expand

/* Have problems using posix barriers when symbol value is 200112L */
/* This requires more investigation, but will work for the moment */
#if defined(_POSIX_BARRIERS) && ( (_POSIX_BARRIERS - 20012L) >= 0 && _POSIX_BARRIERS != 200112L)
#define _POSIX_BARRIERS_MINE

floating around the great internet. Exactly what it does who knows...

[Ters]

Is the preprocessor supposed to be smart enough to recognize L as a legal part of a numeric value?

[Dwachs]

The header file that defines _POSIX_BARRIERS is not included ...

Preprocessor can work with L

Edit: Hopefully fixed with r6646
