Thread: Build failure on OSX

Hi

I'm getting linker error on OSX since about two days. Any idea why the symbol __ftol is missing,
and which library should provide it?

i haven't yet tried a recent build here, but i DO remember seeing ftol
b4 ... though on PC-boxen.

doing a little quick digging, it seems ftol is related to runtime
Floating-Point-to-Int conversion; cref e.g. this thread --

http://lists.apple.com/archives/PerfOptimization-dev/2005/Jan/msg00027.html

reading the thread, i'm fairly certain ftol is NOT avail on PPC ... but
perhaps on Intel?

florian, what box are you building on?

has someone here, perhaps, been monkeying with Intel code for the new macs?

just guessing for now ...

richard

OSX 10.3.9 on an old G3 350Mhz, with the newest devtools available for
10.3 IIRC.

I found the error. misc.cpp defines _ftol or _ftol2 as "extern". Whoever
added that code seems to have believed that "#if (_MSC_VER < 1300)" will
evaluate to false if _MSC_VER is not defined ;-) It doesn't, howerver,
so this needs wrapping inside "#ifdef WIN32".

Heres a patch, please apply.
