[Developer Guide] How to compile this project

[HerringtonDarkholme]

It should be tracked by #45, but in case you cannot compile this project, here is my try.

Prerequisite:

Make sure you have sbt, java and clang installed. My version:

$ java -version
java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)

$ sbt -version
sbt launcher version 0.13.8

$ clang++ -version
Apple LLVM version 5.1 (clang-503.0.40) (based on LLVM 3.4svn)
Thread model: posix

And optionally, if you don't have gc.h in your lib path. Please refer to this to install it.

clone this project

git clone https://github.com/scala-native/scala-native.git --recursive
cd scala-native

Note the recursive option because scala-native requires scala as submodule.

publish localDeps

$ sbt
project rtlib
publishLocal
project nscplugin
publishLocal

run demoNative

still in the sbt session

project demoNative
run

And Finally I got an error from clang++, which reads error: expected '{' in function body llvm

Hope this will help.

Same point:

demonative-out.ll:152:40: error: expected '{' in function body
declare double @"llvm.sqrt.f64"(double)

and

rt.cpp:3:10: fatal error: 'gc.h' file not found
#include <gc.h>

My configuration is:

clang++ --version
Ubuntu clang version 3.6.2-1 (tags/RELEASE_362/final) (based on LLVM 3.6.2)
Target: x86_64-pc-linux-gnu
Thread model: posix

and

java -version
openjdk version "1.8.0_91"
OpenJDK Runtime Environment (build 1.8.0_91-8u91-b14-0ubuntu4~15.10.1-b14)
OpenJDK 64-Bit Server VM (build 25.91-b14, mixed mode)

[andreaTP]

update:
gc.h can be fixed by installing manually BOEHM GC for example as explained here:
https://github.com/crystal-lang/crystal/wiki/All-required-libraries

[andreaTP]

got it working on Linux!!!!

You will need to update clang and llvm to 3.7 version.

Going to try to write a usable guide.

thanks also to @andreaferretti

[timothyklim]

on OS X too:

Rendering (8 spp) 100.00%

[rockjam]

Got it working on OS X after this

[kmizu]

Got it working on OS X after placing the file to pass additional options to clang on demo-native directory. !

[mkotsbak]

gc.h for Ubuntu is as easy as doing:
sudo aptitude install libgc-dev

[andreaferretti]

I have a working container for Vagga: see here

[easel]

These worked for me on OS X after installing the llvm/gc stuff via home-brew. Very nice.

[andreaTP]

I mad a PR with a Docker configuration to run it:
#56

[joprice]

Anyone else getting errors encoding errors in javalib/doc? I tried setting utf8 flags for scalacOptions, javaOptions, etc, and running dos2unix over all files.

[mkotsbak]

I don't get it to compile: #68
What is the required version of clang? I just see an Apple version above. In my Ubuntu I have 3.5, 3.6, 3.7 and 3.8 available.

[andreaferretti]

You need clang 3.7 at a minimum. See this Vagga file or this Dockerfile for complete instructions.

[josdirksen]

Also got it working on OS-X Yosemite.

Got this:

rt.cpp:3:10: fatal error: 'gc.h' file not found
#include <gc.h>

Which was solved by installed boehm gc, and also got this:

demonative-out.ll:152:40: error: expected '{' in function body
declare double @"llvm.sqrt.f64"(double)

Which was solved by using brew to install llvm and clang++ 3.7 and adding those to the front of the path.

C:\>clang++ --version

Once I get pass here, I'll deal with needing Boehm

[andreaTP]

@josephwinston did you clone with --recursive ?

[josephwinston]

@andreaTP I thought so. I'll try starting over from scratch to see if it is user error.

[josephwinston]

@andreaTP No joy after a deleting what I had and then running git clone --recursive https://github.com/scala-native/scala-native.git. I then followed the recipe here http://stackoverflow.com/questions/6631694/replace-git-submodule-protocol-from-git-to-http/6632693#6632693 to switch from git to https. The same traceback.

[andreaTP]

@josephwinston sorry I haven't got access ti any windows machine I can test on... Could you give a try to my docker support? manage.sh will not work but the docker commands are trivial to reproduce....

[josephwinston]

I'll switch to one of the other platforms.

Using Apple LLVM version 7.3.0 (clang-703.0.31) compiled with -O3 on demo-cpp

demo-native compiled with the same level (-O3)

We've got initial build instructions and docker image merged recently. Feel free opening pull requests if you want to improve those. We're also working on making linux build easier in #102 .
