Bug 153484 – [GTK] FTL JIT fails to initialize LLVM on Ubuntu 15.10

• Status: RESOLVED
• Resolution: WONTFIX
• Component: New Bugs

[Csaba Osztrogonác]

Since https://trac.webkit.org/changeset/195009 FTL JIT JSC tests fails for me on Ubuntu 15.10.

$ export JSC_verboseFTLFailure=true
$ Tools/Scripts/run-javascriptcore-tests --gtk

ERROR: Unexpected exit code: 139
Failed to load LLVM library at libllvmForJSC.so: libLLVM-3.7.so: cannot open shared object file: No such file or directory
Failed to load LLVM library at /usr/local/lib/javascriptcoregtk-4.0/libllvmForJSC.so: /usr/local/lib/javascriptcoregtk-4.0/libllvmForJSC.so: cannot open shared object file: No such file or directory
LLVM can't be initialized.

Have you got any idea what can be the problem and how to fix it?

[Csaba Osztrogonác]

Of course the lib can be found on its proper place:
WebKitBuild/DependenciesGTK/Root/lib/libLLVM-3.7.so

[Csaba Osztrogonác]

$ export LD_LIBRARY_PATH=/home/ossy/WebKit/WebKitBuild/DependenciesGTK/Root/lib
fixes this issue ... but I think it should work out-of-the box.

I think the root of the bug is the same as in bug150933.

WebKitBuild/Release/bin/jsc works without setting LD_LIBRARY_PATH
environment variable, but it links to system libs instead of
the proper libs built by jhbuild.

Is run-javascript-core-tests actually entering the JHBuild environment properly?

[Csaba Osztrogonác]

LLVM based FTL JIT will gone away soon, so it won't be problem with B3 FTL.
