[RoboVM 1.9.0] Segmentation fault during the compilation of a Linux x86 console application #1177

Open thgard opened 8 years ago

Hi,

I tried to compile a HelloWorld example using RoboVM 1.9.0 and the corresponding Maven plugin for Linux x86.

Every time I get the following segmentation fault:

#

I tried it on Ubuntu 12.04 LTS x86 with g++ 4.7, Oracle JDK 1.7.0_80, build-essential, gcc-multilib, g++-multilib and zlibc installed.

The x86_64 build on another machine (14.04LTS, x64) finishes successful, but the x86 build fails too.

I had a look at the log files in the Google Groups post and they seem to be for the attempt on Linux (Ubuntu 12.04?) i386. Do you get the exact same crash on Ubuntu 14.04 x86_64? Can you please provide the logs for that? And make sure you are using a 64-bit JVM otherwise the 32-bit LLVM binaries will be used. We are aware of issues with the 32-bit LLVM binaries (#681).

Also, please provide the code you are trying to compile as well as the project (Maven) files. I will try to compile a simple "Hello world" program on Ubuntu 14.04 64-bit to see if that works here.

Ok, just tried to compile the HelloWorld-console sample in 32-bit mode on Ubuntu 14.04 64-bit with a 64-bit JVM and it fails with a SIGSEGV. Here are the steps I took:

git clone git@github.com:robovm/robovm-samples.git
cd robovm-samples/
cd HelloWorld-console/
mvn -Drobovm.arch=x86 compile robovm:console

I had the same result with nearly the same configuration. Therefore I won't do double posting my results.
