I already have a completed builder for 7zip but honestly never looked at the final file size  ???
Version: 24.09 Stable
Patched...
...compiling...  (ding!)

Stripped (x86_64) looks to be about 3.5Mb - but even so...  might be worth packing into the builder system!?

UPX that and you may make it even smaller :)

Last I knew, UPX isn't lossless.  Any problems experienced in its use with 7Z and/or 7Z compiled with ASM injections?
Yes, I get about a 64% reduction in physical file size using -9 but I'm curious at what cost, if any.
Appreciate the ongoing communications!

Hi CentralWare
Their github page is titled:

If that's true, the compression must be lossless, otherwise the
executables would never execute again.

I do not know how "others" compile/link/optimize (gcc 15?, llvm?), but their size is less than yours 3.5MB (not UPX-ed)
