Compile options to reduce FreeOrion's memory consumption

#1 Post by Apo »

Two of Debian's build servers are running out of memory when compiling FreeOrion. Those are architectures like mips and s390 whose build servers are only equipped with 3 GB physical RAM and 2 GB swap.

I have found this topic about reducing the memory consumption at build time. http://www.freeorion.org/index.php/Comp ... _FreeOrion

What else can I do to reduce the memory consumption besides using just one thread and passing -fno-var-tracking to CFLAGS? (I haven't tried that yet but I'm curious if there are more solutions to this problem) Thanks!

As noted here yandonman found that for MSCV optimizing for small code size allowed him to build some components he hadn't been able to before; the corresponding gcc option would be -Os

Where in the compilation process does it run out of memory?

s390 build log
https://buildd.debian.org/status/fetch. ... 1376218408

The build fails with
virtual memory exhausted: Cannot allocate memory
when building GiGi.

mips build log
https://buildd.debian.org/status/fetch. ... 1376265330

Same error message but with the additional BOOST_STATIC_ASSERTION problem in any_regular.hpp:689

GiGi? I don't imagine the FreeOrion parsers will compile then...

Please reread the log. It chokes on IntValueRefParser.

Code: Select all

virtual memory exhausted: Cannot allocate memory
make[4]: *** [parse/CMakeFiles/freeorionparse.dir/IntValueRefParser.cpp.o] Error 1
You also build with 4 parallel processes, reduce them to one.

Yep, my bad! Will try with one process again.
