How can I build a static lepton binary

[pstibrany]

Is there a way to build static lepton binary to avoid library dependencies issues across machines?

[danielrh]

Yes: I've done so before--
the CMakeLists should do so by default

otherwise I believe you can pass
LD_FLAGS=-static ./configure

Using cmake as described in README has indeed produced static binary. Thanks!
Maybe it would be worth mentioning in README? :)

It turns out that lepton compiled with cmake+make is much slower at compression (0.34 MiB/sec on my Linux machine) than lepton compiled with autogen.sh + configure + make (2.75 MiB/sec, same machine, same input).

Any idea why what may be the case?
Thanks.

LDFLAGS=-static ./configure && make also produces statically linked lepton, which is as fast as dynamically linked one produced by configure and make. Still I think it would be good to fix slowness of lepton when using cmake, so that others don't run into it.

sorry for the late response
with cmake you need to specifically tell it to build in RELEASE mode without debug flags
cmake .. -DCMAKE_BUILD_TYPE=Release
otherwise it will build with a ton of self check features enabled. Not a great default to have, I suppose

Ah, ok. I have never used cmake before, and living mostly in Java and Go worlds, I have long forgotten about concept of release builds :-) Thanks for help.
