Hmm, the make file already has 2GB per process set up.

https://git.ipfire.org/?p=ipfire-2.x.git;a=blob;f=lfs/dnsdist;h=9f2040f16583e033f624e24415953396a4d9e526;hb=HEAD#l40

So it will launch one compiler process per 2GB of memory. Obviously less than one isn’t possible.

You can try filtering out “-pipe” from the CFLAGS and CXXFLAGS, so that the assembler will be stared after the compiler is done and not in parallel. That will also save a couple of megabytes, but probably not a massive lot.

In general I can recommend to add more memory to your build system. 4GB seems to be a bit of a sweet spot. More than that normally does not make any difference.

Best,
-Michael
