Errors building LDC with DMD managed by DVM

[Hackerpilot]

I use dvm to manage my installs of DMD. This means that the Phobos shared library for the compiler used to build LDC is not installed system-wide.

It seems that LDC is being dynamically linked with Phobos, so running LDC fails with the following error:

/home/alaran/src/ldc/build/bin/ldc2: error while loading shared libraries: libphobos2.so.0.70: cannot open shared object file: No such file or directory

I thought Phobos wasn't used in the ddmd front-end. So why would LDC depend on Phobos at all?

[JohanEngelen]

DDMD depends on druntime, and for DMD libphobos=phobos+druntime

[kinke]

for DMD libphobos=phobos+druntime

So... what? ;)

[JohanEngelen]

Ah :) I thought it would explain why LDC seems to depend on phobos.

[kinke]

But linking with druntime alone should suffice, right? So we should leave Phobos out of it. It probably won't help with the issue at hand though, as the shared druntime lib won't be found either. That doesn't look like an LDC issue per se to me though.

Sorry I was so unclear: to me it seems DMD does not have druntime separate from phobos. They seem to be put together in "libphobos" library. (I only see a libphobos in my DMD folders)

That doesn't look like an LDC issue per se to me though.

I had the same problem as OT and thought it was a DMD issue too.

[kinke]

Ah, thank you very much for clarifying the 'libphobos' thingy.

@Hackerpilot: Is this specific to LDC? It seems as if you would have this problem for every D executable built with DMD.

[JohanEngelen]

But I guess he is linking with the C++ linker still (master). @Hackerpilot Can you try with the branch of this PR #1368 ? In that PR, we use DMD as the final linker to make the executable.

[Hackerpilot]

That branch works.

#1368 has been merged to master now. Thanks for testing!
