Building LDC fails with link errors #2788

Closed PetarKirov closed 6 years ago

PetarKirov commented 6 years ago

I was eager to try the support for WebAssembly (great work guys!) and I decided to build ldc myself (since I expect to do some hacking on druntime / phobos), however I ran into link errors.

Here's my script to build ldc:

#!/usr/bin/bash

if [[ -v USE_LLVM_WITH_ASSERTS && $USE_LLVM_WITH_ASSERTS -eq 1 ]]
then
    LLVM=llvm-6.0.1-2-linux-x86_64-withAsserts
else
    LLVM=llvm-6.0.1-2-linux-x86_64
fi

set -euxo pipefail

wget https://github.com/ldc-developers/llvm/releases/download/ldc-v6.0.1-2/$LLVM.tar.xz
tar xvf $LLVM.tar.xz
git clone --recursive https://github.com/ldc-developers/ldc
mkdir ldc/build && cd ldc/build
cmake -G Ninja -DLLVM_CONFIG=../../$LLVM/bin/llvm-config ..
ninja

Here's the build output from ninja:

ninja: build stopped: subcommand failed

(The build fails in the same way no matter if I use the llvm built with asserts or not.)

If I then do ninja clean && ninja ldc2 from the build dir I get this:

I tried building with either dmd or ldc activated (via the install.sh script) but I got the same result. The failure is really strange considering that your various CIs must have done multiple successful builds of the same thing.

PetarKirov commented 6 years ago

Since the problem at the linking stage, my guess is that there's some ABI incompatibility between my local compiler (gcc/g++ 8.1.1 20180531) and the compiler that was used to build the release of your fork of llvm. I also tried clang/clang++ 6.0.1 (tags/RELEASE_601/final), but I get the same error.

I'll try building your llvm fork locally and see how it goes.

Yep, that's almost certainly the culprit. The prebuilt LLVM is built on Ubuntu 14.04 with backported g++ 6.4.

PetarKirov commented 6 years ago

Yep, building llvm with GCC 8 solved the issue for me. Curiously enough my first attempt at building llvm with clang failed with another linker error:

$ cmake -G Ninja -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=(dirname $PWD)/llvm-x64 -DLLVM_TARGETS_TO_BUILD="AArch64;ARM;Mips;MSP430;NVPTX;PowerPC;X86" -DLLVM_EXPERIMENTAL_TARGETS_TO_BUILD="RISCV;WebAssembly" -DLLVM_ENABLE_ASSERTIONS=$LLVM_ENABLE_ASSERTIONS -DCOMPILER_RT_INCLUDE_TESTS=OFF $extraCMakeFlags ..

Anyway, I now managed to compile ldc and build my first working wasm program with simply ldc2 --mtriple=wasm32-unknown-unknown-wasm -betterC --link-internally, amazing!!! :heart_eyes:

joakim-noah commented 6 years ago

Btw, unrelated to this issue, but someone with a HN account want to set this Rust guy straight on building ldc (see first response to Walter)? It's never taken me 10X as long to build ldc as dmd, plus not sure how he blames a pre-built LLVM for the difference.

kinke commented 6 years ago

[I don't have an account and don't plan on getting one.] But a build taking 21 mins on a non-ancient x86 machine is a ridiculous statement. Even CircleCI manages to build in just under 4 minutes, incl. default libs.
