Compiling jar with aura fails

[Zubnix]

Trying to compile an existing java jar with aura fails with error (I used the instructions in the wiki):
Exception in thread "main" java.lang.UnsatisfiedLinkError: Native library for linux-x86_64 not found
at aura.llvm.NativeLibrary.load(NativeLibrary.java:72)

when trying to compile the 'llvm' native build, using the provided 'build.sh', I get the following error:

[ 55%] Performing patch step for 'extllvm'

Perhaps you used the wrong -p or --strip option?
The text leading up to this was:

Perhaps it is related?

I built this a few hours ago on centos

Only thing I can think of is for some reason libclang/CMakeLists.txt file doesn't exit

$ find . -name CMakeLists.txt | grep libclang
./extclang/tools/libclang/CMakeLists.txt
./extclang/unittests/libclang/CMakeLists.txt
./target.llvm/build/linux-x86_64/extclang-prefix/src/extclang/tools/libclang/CMakeLists.txt
./target.llvm/build/linux-x86_64/extclang-prefix/src/extclang/unittests/libclang/CMakeLists.txt

Can you see it there?

[Zubnix]

yeah looks like it's there:

zubzub@localhost ~/git/aura $ find . -name CMakeLists.txt | grep libclang
./llvm/target.llvm/build/linux-x86_64/extclang-prefix/src/extclang/tools/libclang/CMakeLists.txt

What patch & cmake version do you use? GNU patch 2.7.5 & cmake version 3.4.3 on this machine.

[ashleyj]

cmake 2.8.11 on centos
Patch version: GNU patch 2.7.1

[ashleyj]

Doing some googling looks like there is/was a bug with 'patch' not following symm links -- could be related to that

[Zubnix]

A quick first investigation also makes me suspect that to be the problem.

[Zubnix]

any patch version > 2.7.3 fails (so that means 2.7.4 & 2.7.5). Since 2.7.4 patch refuses to follow symlinks of directories. I advice including it in the wiki :)

[Zubnix]

using 2.7.3 seems to fix the original issue. however I do seem to get an error pretty far on during compilation. (not compatible libxml2 found). Are you willing to provide the info (dependencies) required to build the aura/robovm llvm to the wiki as well?

[ashleyj]

I've added a list of deps I've identified here: https://github.com/ashleyj/aura/wiki/Compiling-Aura
If you come across any I've missed, let me know.

[Zubnix]

I was able to fix the libxml2 issue by installing a multilib compatible variant (32 & 64bit x86 ABI). Maybe other distro do this by default (I had to explicitly tell gentoo to enable 32 bit ABI for libxml2).

I did not need to install anything specifically to make the compilation succeed so I can not comment if the dependency list is complete or not.
