Windows support about cxx.jl HOT 18 OPEN

After some more make cleanall and the like, it seems to build llvm... Also I'm using make instead of make -j4. I'll see if it finishes this time.

from cxx.jl.

Hmpf...

I built 3.6 on windows a few days ago but julia wouldn't start. Haven't
drbugged yet. Anyway this is a julia issue first... see the llvm 3.5
support issue.

from cxx.jl.

What issue are you talking about? So are you suggesting, that something in Julia needs to be fixed? This whole build system is a big mystery to me ;)
I don't really know what else to try, last thing I tried was to build with override LLDB_VER=release_33

from cxx.jl.

I tried a few more things and everything ends up in the same error.
Any ideas or hints? Should I open an issue over at Julia?

from cxx.jl.

I think the umbrella issue is this: JuliaLang/julia#9336

We were just looking into the status of Cxx on Windows today. It might be good to see if you can build and other wise vanilla Julia expect for LLVM 3.5 and see if that works.

LLVM, Julia, and Cxx are all really fast moving targets. I tend to stay with one 0.4 build for a week or so until Cxx is updated or there is some feature/bugfix I want. Even then, I tar my julia build incase something goes wrong, so I can atleast still work.

from cxx.jl.

lldb works on windows?

from cxx.jl.

I don't think so.. I already tried deactivating it, as I thought it isn't really needed, but I think I got other errors...

from cxx.jl.

that's the error I get when I deactivate LLDB:

Is this related!?

I can successfully compile 3.0.17 using the mingw-64 compiler without
issues. I haven't tried 3.0.22 yet. I do all of my work under MSys. I
try to avoid cygwin; see below.

configure (and configure.ac) look for vasprintf. The scripts do not look
for asprintf, specifically. Two reasons why you might have problems:

a) cygwin: The mingw-64 toolchain may be picking up a header from
cygwin. This header's declarations for asprintf and vasprintf differ
from what gnutls' replacement thinks it should be.

b) You didn't specify "--host=x86_64-w64-mingw32" as an argument to
configure.

Both (a) and (b) are related -- if you didn't give "--host" to
configure, then it is possible for toolchains to pick up headers they're
not supposed to find. You might also need to unset your settings for CC
and CFLAGS as well.

Hope this helps you get a little farther.

Where would I specify this?

from cxx.jl.

I tried building julia + llvm-svn with the Cxx.jl Make.user. Aside from the LLDB includes issue above (which is tractable) the bigger issue is that currently Cxx.jl needs to have access to a shared LLVM library. However, building a shared LLVM on Windows is not supported. I guess the work-around there may be to link in the C++ helper code inside libjulia?

from cxx.jl.

That's false, but you might need this

from cxx.jl.

I see. Indeed it (Julia) does build with that patch, and JuliaLang/julia@fc3df96.

from cxx.jl.

Can you get another reviewer for that patch, or just commit it? (would be nice to get it backported to 3.6.1 too)

from cxx.jl.

Yes, I'll get it in somehow.

from cxx.jl.

With a few minor patches, I got most of the way through building lldb against llvm-svn in the cygwin mingw-w64 cross-compiler setup. However, the remaining (large) issue is the several usages of std::call_once and family. Those are not currently supported by mingw-w64 with the win32 thread model. (discussion on llvm-dev)

from cxx.jl.

Breadcrumb for future: https://github.com/meganz/mingw-std-threads might be useful for the mingw-w64/C++11 threads question (though does not provide std::call_once).
