Static executable (ldc, linux)

[Anonymouse]

I'm having problems compiling my thing into an executable that 
doesn't require ldc's phobos/druntime .so's. I want to distribute 
it in a form where it's okay if 
`/usr/lib/libphobos2-ldc-shared.so.100` and friends don't exist.

`--static` seems to do the trick in that the compiled file is no 
longer a dynamic executable, but then it doesn't work and just 
segfaults upon trying to use OpenSSL (via `arsd.http2`). The only 
other flag I specifically pass to ldc is `-linkonce-templates`.

dmd seems to do this by default (`ldd` doesn't list any phobos or 
druntime .so files and program doesn't segfault), but I'm not 
sure how I can get ldc to behave the same. I looked over the 
`--help` listing but I could only find `--static` (and `--lib`, 
which I assume doesn't apply here).
