decide on branch policy about libclang

[sethfowler]

I agree, once #33 is fixed.

[ghorn]

awesome. getting excited about the status of this library

[sethfowler]

Since I suspect a new release is coming soon, I'm going to go ahead and merge the llvm3.4 branch to master and delete llvm3.3.

We now know that we need GHC 7.8 to be released to fix #33. I'm hopeful that happens soon, in which case @chetant's code in llvm3.4_ghc7.8 should take care of the problem once it's rebased and merged.

[chetant]

@sethfowler FYI, I'd recommend you rebase now, as that code also works with ghc 7.6.3 (that's the only version I tested it with).
ghci 7.6.3 doesn't work, but the static linking is fine and much more imp. the linking does not depend on an external build directory.

[sethfowler]

@chetant, great, I didn't realize that!

I'm suffering from build system fatigue at the moment (the update to the release version of LLVM 3.4 was a bit bumpy) but I'll plan to do the rebase soon.

[chetant]

@sethfowler , just merged llvm3.4_ghc7.8 with master and fixed tests, put the -j4 flag for make back in, as I couldn't find a decent workaround. Tested on ubuntu 13.10, ghc 7.6.3 and ghc-HEAD. We're getting close to an actual release on Hackage! Could you confirm this works on a Mac?

[sethfowler]

@chetant, fails on OS X for me. Looks like it's not pulling in libstdc++ correctly. Here's the log:

I have to go do some other stuff for a little while, but I'll try to debug this more later tonight.

I'm going to reopen this bug until we get this resolved.

[sethfowler]

I'm sure it's clear, btw, but that's a log from building pygmalion, not from LibClang. LibClang itself builds fine, but clearly the linking story isn't quite right.

This is with GHC 7.6.3.

[sethfowler]

Pretty sure the problem is that we now lack the ability to do the equivalent of listing -lstdc++ a second time when linking, as I did in the old Setup.hs. Listing it that second time allowed the linker to resolve symbols from the C++ standard library that the LLVM static libraries reference. Without including that we get link failures when we build a program that depends on LibClang.

Unfortunately, it's not so clear how to solve this problem when we're packing a static library manually with ar. Making the situation even worse is that clang does not seem to support the -static-libstdc++ option, which I was hoping would let me work around the problem by building LLVM/Clang with a static libstdc++ linked in from the beginning.

I've tried a number of other options and so far haven't had much luck. I've got one or two more things to try, though.

[sethfowler]

Ack, none of that worked out.

@chetant, I'm sorry, but I need to back this out for now. I'm going to rebase master so your commits are on top and then move them to branch newbuild so you won't lose your merge work.

I'll file a new bug about the problem in my last comment so we can put this old bug to rest.
