Default NetBSD - ldconfig, ld cache

hi, all.
some days ago I found emacs extension - auto-complete-clang-async - for C/C++ autocomplete with LLVM backend. I build and install clang from pkgsrc, but when I try to build this extension with make tool, I encountered with several problems:

1) libc++.so - standard c++ library for clang++ isn't represented in system, not in /usr/lib, /usr/pkg/lib paths;

2) I can't find ldconfig(8) in my system for create libraries links cache, however there are man page for it. 'locate libclang.so' and 'locate libc++.so' shows nothing and I think ld(1) don't know about clang libraries.

thnx.

sorry for my english, I need more practice

I must begin by saying I'm not familiar with clang, and only use pkgsrc binary packages, but with that in mind, a couple of thoughts for you to follow up on:

I would expect to find ldconfig at /sbin/ldconfig. Is this not there on your system? It is part of the base.tgz package.

I downloaded the clang-3.4nb1.tgz binary package to a shell account. It doesn't seem to contain libc++.so, but there is a libclang.so that I expect would be installed as /usr/pkg/lib/libclang.so. Did your pkgsrc compilation of clang install that?

thnx for your reply!

I installed clang package from source with 'make install clean' and found clang binary and clang++ symbol link in /usr/pkg/bin path. llvm-* binaries installed too.

Already I checked ldconfig location in /sbin, that there is no. NetBSD was installed with full configuration (base, compile tools, x11, etc.). may be certain package contains this util?

Did it also install /usr/pkg/lib/libclang.so ?

Sorry, my mistake, it seems for amd64 there is no ldconfig (but there is still for i386). But, you probably don't need it as the man page ldconfig(8) says that for ELF systems ld.elf_so(1) is used instead. Perhaps the information in these man pages will be helpful?

yes, libclang.so located in /usr/pkg/lib/, it is correct. now I'll try to use llvm-config for automatic definitions paths and libraries for clang.

you're right, I casually read man page for ldconfig.

deviate from the topic, do you used pkgsrc-wip project for build virtualbox? actually, I have some quetsions in point of wip. should I create new thread for it?

Sounds good that the library is there, I hope the rest will work.

The man pages are excellent sources of info, always worth reading. And yes sometimes we all forget to do that.

No, I've never used virtualbox myself, and I only use binary packages. Yes it would be good to create a new thread for this, as it helps people who may search for a topic find focused information. So don't be shy to create a new thread.

o'k. I solved my problem as folllows:

current version of clang is 3.4. This version contain problem with absence libc++.so that implement clang STL after installing. I just installed a previous version clang-3.3 with pkg_add -v and now all libraries and paths are set correctly. I found bug reports about clang-3.4 and believe that error will be fixed soon.
