Re: HSAIL unit tests fail when Okra library fails to load

I don't think they are conflicting. /lib/libc.so.6 is part of the package glibc-2.8-3.

That's puzzling - how does rpm square with what ldd is reporting? Is glibc loaded dynamically, in which case my experiments are missing the point...

Hi - catching up on my email backlog:


Not sure what glibc version that is, though.
For Linux builds, others on build-dev@openjdk.java.net are more knowledgeable about glibc used in different JDK releases.
Hmmm - these README-builds.html files do not mention a specific glibc version:
http://hg.openjdk.java.net/jdk8u/jdk8u-dev/raw-file/tip/README-builds.html
http://hg.openjdk.java.net/jdk7u/jdk7u-dev/raw-file/tip/README-builds.html 

I ran a little test on one of our Fedora 9 build/test systems:

What glibc does Hotspot build against?


I’m not sure - Christian may know (or know who knows).


Looking at some wiki pages JDK 8 is building on:

Fedora 9 / GCC 4.3
Not sure what glibc version that is, though. Tim Bell is the right guy to ask.

Hi Doug,
Do you think it is worth it to build the built in Okra simulator with
an older glibc to help avoid this problem? What is the oldest distro you 
intend to support with Graal?
In theory we should support whatever HotSpot does although in practice 
we only need it to work on OSes for which we build distributions.

However, I think it's fine (for now at least) if we just cleanly
ignore/short-circuit the HSAIL unit tests in question on platforms with 
an older glibc.

Hi Tom, Eric,

We're in the process of making GraalVM binary builds that work on
Oracle Linux 6.5 which has an old version of glibc (GLIBC 2.12). While 
testing this build, the HSAIL tests that use the Okra library fail
because libokra_x86_64.so is built against a version of GLIBC later than 
2.12. However, the failure message is very confusing. For example:


$ mx --vm server unittest Vec3ObjStreamClassCastTest
GraalJUnitCore
JUnit version 4.11
.E
Time: 0.77
There was 1 failure:

Can you please make sure the HSAIL test harness recognizes a failure
to load the Okra library (preferably issuing a message if it's for any other reason than the library not being available). One way to trigger 
this is to fake a bad library:


$ mkdir -p resources/okra/Linux
$ echo "bad" >resources/okra/Linux/libokra_x86_64.so
$ jar uvf lib/okra-1.9-with-sim.jar

resources/okra/Linux/libokra_x86_64.so

$ mx --vm server unittest Vec3ObjStreamClassCastTest
