Memory demanding compilation for pyopencvext_free_functions.pypp.cpp #4

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
It is not a defect but IMHO it would be great if some modifications could be 
made.

Compilation of pyopencvext_free_functions.pypp.cpp failed due to out of memory 
error. Error 
description is attached.

Tested on Linux and Mac OS X boxes. Both boxes have 2GB RAM and no other 
intensive 
processes. Managed to compile it by a naive solution of splitting the file into 
three.

"g++"  -ftemplate-depth-128 -O3 -finline-functions -Wno-inline -Wall -
I/opt/local/include/opencv -I/Users/zhuj/Temp/boost_1_41_0 -Ipyopencv -

That's strange because on my Ubuntu 9.10 on VirtualBox with only 256 MB of RAM, 
the
code can be compiled just fine. But I agree that the file is too large. I will 
find a
way to divide it into smaller pieces.

Then I think it may be related to the version of gcc I am using, which is 
4.2.1. Thanks for letting me know.

FYI, I have splitted pyopencv_free_functions.pypp.cpp into multiple files since 
r799.
The change will be updated in the next release.

Cheers,
