digitalmars.D.learn - dub ldc2 static linking

reply Yura <yuriy.min gmail.com> writes:
Dear All,
I am trying to create a static executable to be able to run it on 
virtually any linux x86_64 OS. At the end I get a binary, 
however, multiple warnings are printed after compilation.

My dub.sdl:

dependency "mir" version="~>3.2.3"
dependency "lubeck" version="~>1.5.1"
lflags "-lopenblas" "-lgfortran"
dflags "--static" "-O3"

dub build --force --compiler=path_to_ldc/ldc2

curl.d:(.text._D3std3net4curl7CurlAPI7loadAPIFZPv+0xd): warning: 
Using 'dlopen' in statically linked applications requires at 
runtime the shared libraries from the glibc version used for 
linking

and many other warnings like this.

What am I doing wrong? Any way to fix it?

Thank you! I tried this one, but it did not help. All these 
warnings survived :
"... Using 'getservbyport' in statically linked applications

used for linking"

For fully static linking on Linux, you'll need to move away from 
glibc to e.g. the musl C runtime, as used by the Alpine distro.

I'm just right now having an issue with glibc version mismatch 
for my server, so i'm looking to move to musl to avoid that kind 
of issues

Is there any guide to compile ldc with musl and then static link 
it?

Actually nvm, `-static` as mentioned above seems to be enough

Static on alpine is possible - be aware of ‘ldc-static’ package. 
But static and LTO is something harder.. is it even possible 
without re-compilation of ldc-runtime?

Just compile with an old enough glibc, 2.14 works for me.

Indeed, if I got it right it seems to be much easier and 
straightforward than recompiling virtually everything you touch 
against musle, starting from Blas, druntime library, etc.

This has nothing to do with dub and is not a D issue 
specifically. Enter your error message in Google and you'll get a 
long list of results. Maybe one of them can help you.

Or do what kinke suggests :-)
