Re: [Inkscape-devel] buildtool update

7 Mar 2016

      Quick update: Just tested multi-threaded compilation with btool and 
Inkscape seems to build just fine.
@Nicolas and Johan:
Do you know of any reasons not to use multiple compilation threads or 
did this simply go unnoticed so far?
Otherwise I'll update the recommended command line in the Wiki to 
include the "-fopenmp" flag so people can actually profit from this feature.
Regards,
Eduard

Hi Luca,
OpenMP is necessary for multi-threaded compilation (which I did not try
myself yet).
So if you currently use the "-j" switch of btool to use multiple
compilation threads you might want to keep the -fopenmp flag. Otherwise
it's unnecessary.
Regards,
Eduard
P.S.: I *think* I read about issues with multiple compilation threads in
btool somewhere (which is why I never tried to use them so far)  but I
can't remember where... Anybody knows the latest status of
multi-threaded compilation with buildtool on Windows? If it actually
works it could easily cut my buildtimes in half! (if only I had known...
;-) )
Also we might want to update the Wiki since the recommended command line
for compiling does *not* include -fopenmp while we still advertise the
(then useless) "-j" switch

Hi Eduard,
I've written a small batch file to recompile btool using a line I've read
somewhere on this forum. The line is:
 g++ -O3 buildtool.cpp -o btool.exe -fopenmp

Is the '-fopenmp' option significative or should I take it out?
Thanks.
