Upgrade build system to BB2 -- Part 1 #406

Gnimuc · 2019-03-09T15:16:05Z

This PR is for providing an out-of-box user installation experience of Cxx.jl. You could give it a test by (v1.1) pkg> add https://github.com/Gnimuc/Cxx.jl#BB2.

Platform	Status
macOS	✅
Linux x86_64	✅
Linux i686	❌
Windows x86_64	experimental (see #406 (comment) below)
Windows i686	❌
FreeBSD	❓

In short, the package works fine almost on all x86_64 platforms. There is a symbol missing error (clang::FileManager::getVirtualFile(llvm::StringRef, long, long)) on i686 platforms, which is probably due to the incompatibility between LLVMBuilder(only tested with gcc7) and current released 32bit Julia.

UPDATE

Since there are still some compatibility issues between Julia and LLVMBuilder (especially i686 platforms), I won't revisit this until Julia1.2 is released. Currently, the binary build for macOS and Linux x86_64 is working quite well. Windows x86_64 support is still experimental: pre-built binary can be loaded successfully and a lot of examples can work as expected, but other examples may trigger segment faults which, I guess, are due to some unknown bugs in Cxx.

I think the first step is to merge this PR and tag a new release so more people can test this package and submit bug reports. Then we can try to support other Tier 1 platforms until after Julia1.2 is released. It looks like Keno is heading on other important things and doesn't have time to review this, so I'm pinging all you guys here (sorry in advance if this is disturbing), but it would be great if you could help to review/test this PR.

fix #403, fix #398, fix #397, fix #394, fix #393, fix #388

It looks that `dump` is no longer exposed in LLVM release build.

Don't forget to add FreeBSD to the list. 😉

ararslan · 2019-03-09T17:29:59Z

Why delete the Project.toml file?

Gnimuc · 2019-03-10T01:21:02Z

To temporarily workaround a dependency problem, I will add it back in the end.

Gnimuc · 2019-03-10T06:02:05Z

It turns out LLVMBuilder for FreeBSD is currently broken :(

~~Package compiled on Windows, but I got some errors when running the basic example:~~

julia> using Cxx julia> jnum = 10 10 julia> cxx""" #include<iostream> """ true julia> cxx""" void printme(int x) { std::cout << x << std::endl; } """ true julia> @cxx printme(jnum) Invalid bitcast %dummy = bitcast i64 %0 to i32 define void @cxxjl.5(i64) personality i32 ()* @__cxxjl_personality_v0 { top: %dummy.addr = alloca i32, align 4 %dummy = bitcast i64 %0 to i32 store i32 %dummy, i32* %dummy.addr, align 4 %1 = load i32, i32* %dummy.addr, align 4 call void @_Z7printmei(i32 %1) ret void } ERROR: error compiling cppcall: Malformed LLVM Function Stacktrace: [1] top-level scope at none:0

this can be fixed by @cxx printme(Cint(jnum)), so I guess there might be something wrong in the codegen. @Keno could you give some hints on how to debug this issue?

UPDATE

~~This issue was reported on 32bit platforms before: #370~~

UPDATE2

This has been fixed by forcing to use

Cxx.jl/src/bootstrap.cpp

Lines 172 to 173 in c62cb57

 TYPE_ACCESS(cT_int64,LongLongTy) 

 TYPE_ACCESS(cT_uint64,UnsignedLongLongTy)

even on 64bit Windows. ~~However, I don't any idea about how to fix the following segfaults:~~ This error is due to Julia/Cxx can't handle $:(julia_global::Int64) correctly on Windows. It can be fixed by directly insert $julia_global into the cxx_str macro.

I have been using the Gnimuc:patch-mac branch of Cxx lately, but last night gave this branch a try. I got this:

@twadleigh that's due to this commit 7b9dd68 which should be Win32 only.

Why get rid of this? If you do want to get rid of it, you can similarly ditch the assignment above it, since it's just the RHS that will be used/returned.

Is there not still a way to get this automatically, e.g. via xcode-select?

ararslan · 2019-04-11T20:02:37Z

This is really great work! I don't feel fully qualified to review it, but I've left a few comments in-line. Aside from those, I'll note:

LLVMBuilder now supports FreeBSD, so it should be possible to add that here as well
Can the Project.toml file now be reinstated?
Why require Julia 1.1 instead of 1.0?

ref: JuliaPackaging/BinaryProvider.jl#152

Since we're not going to support binary build for v0.7-, these code are totally obsoleted.

Gnimuc · 2019-04-12T14:45:42Z

Hi @ararslan, I've rebased this PR and applied your suggestions. I can successfully build libcxxffi binary for FreeBSD: https://github.com/Gnimuc/CxxBuilder/releases/tag/v0.0.4-1, but I don't have a BSD environment for testing whether the pre-built lib is dlopen-able. We also need to add an init function for it.

This PR is for Julia-1.1+LLVM-6.0.1 only. The main reason is the incompatibility between the official Julia binaries and LLVMBuilder releases. You could refer to previous discussions for details:

It's possible to add binary-build support for Julia-1.0, but I failed to make that work on Windows. For now, the libcxxffi binary used in this PR is actually Julia-master compatible which happens to be compatible with Julia-1.1 x86_64 platforms. It's hard to get everything works without the full compatibility between Julia and LLVMBuilder. Hopefully, we will have it in post-Julia-1.2-era.

ararslan · 2019-04-12T19:43:39Z

I can give it a try on my FreeBSD system, and if all goes well we can turn on Cirrus CI for this repo to test on FreeBSD.

ararslan · 2019-04-12T19:58:00Z

welp staticfloat/LLVMBuilder#45

EDIT: So apparently one should not be opening multiple copies of libLLVM, which is the cause of that issue. What is it that needs to be dlopened in this case? Is it libclang?

Gnimuc · 2019-04-13T00:56:23Z

It's libcxxffi.so, but I think libLLVM should also be dlopen-able.

kraftpunk97-zz · 2019-04-16T14:15:31Z

@Gnimuc Not sure if this is still a WIP, but I got multiple errors when I tried to precompile your #master. Is this behaviour expected?

Gnimuc · 2019-04-16T14:19:59Z

@kraftpunk97 It should work as long as you're working on macOS, Linux(64bit) or Windows(64bit). Could you comment those errors below?

BTW, you may need to manually git fetch the latest master.

It says could not add directory /usr/include to clang search path. Perhaps, this is an easy fix?

aha, I got that /usr/include-missing error before. Apple is the one to be blamed here. It could be fixed by https://apple.stackexchange.com/questions/337940/why-is-usr-include-missing-i-have-xcode-and-command-line-tools-installed-moja

Shouldn't you use the BB2 branch that this PR is based on? e.g. ] add https://github.com/Gnimuc/Cxx.jl#BB2

Yeah, that's actually my bad. I've updated the command in the OP. Currently, I manually keep syncing these two branches.

kraftpunk97-zz · 2019-04-16T21:29:31Z

Thanks @Gnimuc, problem solved

Gnimuc · 2019-04-22T07:24:54Z

Hi @ararslan, did you successfully dlopen libcxxffi.so on FreeBSD? If not, I think we can try it again when Julia 1.2 is released. For now, let's merge this and tag a new version for Julia 1.1.

It turns out macOS SDK headers are not installed in `/usr/include` by default on Mojave.

ararslan · 2019-04-22T18:23:08Z

Sorry for the delay in getting back to you on that. I just tried your FreeBSD-compatible release for CxxBuilder and I can dlopen libcxxffi.so just fine on FreeBSD 11.2 with Julia 1.1.

oschulz · 2019-04-23T12:54:44Z

Seems to work out of the box (CentOS Singularity Container on Ubuntu)! Thanks so much for all your work on this, @Gnimuc and all the other that were involved! I was really missing Cxx.jl ...

oschulz · 2019-04-23T12:57:13Z

Yep, just remembered, lol. Sorry! Hadn't used Cxx for too long. :-)

oschulz · 2019-04-23T12:59:41Z

Another question: Is there an easy way to supply the binary deps in a central location (e.g. a container image), to speed up Cxx installation and keep the user .julia directories small(er)?

Petr-Hlavenka · 2019-04-23T13:06:26Z

Thank you for your effort!
Installs on windows without problem and runs as "experimental" as expected - I've started to fill windows specific issues to #409.

Gnimuc · 2019-04-23T13:15:49Z

@oschulz It's possible to shrink deps size. I tried before but failed to do it correctly. For now, BB just ships the whole LLVM/Clang deps which are very huge. I think we can revisit it after Julia 1.2 has been released.

You could give it a test by |(v1.1) pkg> dev https://github.com/Gnimuc/Cxx.jl.git|. Platform Status macOS ✅ Linux x86_64 ✅ Linux i686 ❌ Windows x86_64 see #406 (comment) <#406 (comment)> below Windows i686 ❌ FreeBSD pending upstream (LLVMBuilder) In short, the package works fine almost on all x86_64 platforms. There is a symbol missing error (|clang::FileManager::getVirtualFile(llvm::StringRef, long, long)|) on i686 platforms, which is probably due to the incompatibility between LLVMBuilder(only tested with gcc7) and current released 32bit Julia. UPDATE Since there are still some compatibility issues between Julia and LLVMBuilder (especially i686 platforms), I won't try this until Julia1.2 is released. Currently, the binary build for macOS and Linux x86_64 is working quite well. Windows x86_64 support is still experimental: pre-built binary can be loaded successfully and a lot of examples can work as expected. However, some examples will trigger segment faults which, I guess, are due to some unknown bugs in Cxx. I think the first step is to merge this PR and tag a new release so more people can test this package and submit bug reports. Then we can try to support other Tier 1 platforms until after Julia1.2 is released. It looks like Keno is heading on other important things and doesn't have time to review this, so I'm pinging all you guys here (sorry in advance if this is disturbing), but it would be great if you could help to review/test this PR. cc @ararslan <https://github.com/ararslan> @cdsousa <https://github.com/cdsousa> @phlavenk <https://github.com/phlavenk> @btaidm <https://github.com/btaidm> @oschulz <https://github.com/oschulz> @ahumenberger <https://github.com/ahumenberger> @grizzlysmit <https://github.com/grizzlysmit> @zsz00 <https://github.com/zsz00> @ervinbosenbacher <https://github.com/ervinbosenbacher> @DrKrar <https://github.com/DrKrar> @skariel <https://github.com/skariel> ------------------------------------------------------------------------ You can view, comment on, or merge this pull request online at: #406 Commit Summary * `dump()` => `print(llvm::errs(), false)` * `contains` => `occursin`, a upgrading oversight * fix-up * Fix REPL mode * Misc. upgrading oversight * fix-up * Update cxxstr.jl * fix-up * Merge pull request #1 from cdsousa/patch-mac * Fix segmentfault * Bump Julia version and update CI * Upgrade build system to BB2 --take 1 * Delete Project.toml * Upgrade build system to BB2 --take 2 * Workaround for Windows ABI mismatch * Fix another Windows glitch * Safer path separator solutions * Fix source file path separator for Windows * Add `__cxa_atexit` as per suggested in #145 * Update build_libcxxffi.jl * Remove meaningless GC preserve * Only define `__cxa_atexit` on Windows * Update build_libcxxffi.jl * Try to fix CI on macOS * fix-up * Disable precompile * Use hard-coded xcode path on macOS since `xcode-select` is not continued * Update build_libcxxffi.jl * Add missing libname * Fix signature mismatch * Workaround for building issues on Julia master * Enable appveyor and update badge links File Changes * *M* .gitignore <https://github.com/JuliaInterop/Cxx.jl/pull/406/files#diff-0> (3) * *M* .travis.yml <https://github.com/JuliaInterop/Cxx.jl/pull/406/files#diff-1> (73) * *D* Project.toml <https://github.com/JuliaInterop/Cxx.jl/pull/406/files#diff-2> (12) * *M* README.md <https://github.com/JuliaInterop/Cxx.jl/pull/406/files#diff-3> (32) * *M* REQUIRE <https://github.com/JuliaInterop/Cxx.jl/pull/406/files#diff-4> (3) * *A* appveyor.yml <https://github.com/JuliaInterop/Cxx.jl/pull/406/files#diff-5> (43) * *M* deps/build.jl <https://github.com/JuliaInterop/Cxx.jl/pull/406/files#diff-6> (18) * *A* deps/build_libcxxffi.jl <https://github.com/JuliaInterop/Cxx.jl/pull/406/files#diff-7> (38) * *M* docs/src/examples.md <https://github.com/JuliaInterop/Cxx.jl/pull/406/files#diff-8> (4) * *M* docs/src/implementation.md <https://github.com/JuliaInterop/Cxx.jl/pull/406/files#diff-9> (2) * *M* src/Cxx.jl <https://github.com/JuliaInterop/Cxx.jl/pull/406/files#diff-10> (4) * *M* src/CxxREPL/replpane.jl <https://github.com/JuliaInterop/Cxx.jl/pull/406/files#diff-11> (95) * *M* src/boot.h <https://github.com/JuliaInterop/Cxx.jl/pull/406/files#diff-12> (4) * *M* src/bootstrap.cpp <https://github.com/JuliaInterop/Cxx.jl/pull/406/files#diff-13> (8) * *M* src/clangwrapper.jl <https://github.com/JuliaInterop/Cxx.jl/pull/406/files#diff-14> (4) * *M* src/cxxstr.jl <https://github.com/JuliaInterop/Cxx.jl/pull/406/files#diff-15> (29) * *M* src/initialization.jl <https://github.com/JuliaInterop/Cxx.jl/pull/406/files#diff-16> (47) * *M* src/show.jl <https://github.com/JuliaInterop/Cxx.jl/pull/406/files#diff-17> (6) * *M* src/typetranslation.jl <https://github.com/JuliaInterop/Cxx.jl/pull/406/files#diff-18> (10) * *M* test/clangutils.jl <https://github.com/JuliaInterop/Cxx.jl/pull/406/files#diff-19> (10) * *M* test/cxxstr.jl <https://github.com/JuliaInterop/Cxx.jl/pull/406/files#diff-20> (2) * *M* test/llvmgraph.jl <https://github.com/JuliaInterop/Cxx.jl/pull/406/files#diff-21> (2) * *M* test/llvmincludes.jl <https://github.com/JuliaInterop/Cxx.jl/pull/406/files#diff-22> (2) * *M* test/llvmtest.jl <https://github.com/JuliaInterop/Cxx.jl/pull/406/files#diff-23> (14) * *M* test/qttest.jl <https://github.com/JuliaInterop/Cxx.jl/pull/406/files#diff-24> (2) Patch Links: * https://github.com/JuliaInterop/Cxx.jl/pull/406.patch * https://github.com/JuliaInterop/Cxx.jl/pull/406.diff — You are receiving this because you were mentioned.

@grizzlysmit, unfortunately, Cxx doesn't support binary build for Julia 1.0.x for now. You may need to upgrade Julia to 1.1 firstly and then run dev Cxx. The reason why it doesn't support 1.0 is explained at this #406 (comment).

dump() => print(llvm::errs(), false)

It looks that `dump` is no longer exposed in LLVM release build.
