[meta-java] rpath problem for llvm libs?

[meta-java] rpath problem for llvm libs?

Hi,

I installed openjdk + openjdk-shark on my target and I get:

root@beaglebone:~# java
dl failure on line 696Error: failed
/usr/lib/jvm/java-6-openjdk/jre/lib/arm/shark/libjvm.so, because
libLLVMARMCodeGen.so: cannot open shared object file: No such file or directory

The 'fix' I used:

root@beaglebone:~# for i in /usr/lib/llvm2.9/libLLVM*.so ; do ln -sf $i
/usr/lib ; done

root@beaglebone:~# java
Usage: java [-options] class [args...]
           (to execute a class)

I came up with a number of workarounds, but I'm not sure which is best:

1) do the for ; ln thing in a postinst
2) have llvm install into ${libdir} instead of ${libdir}${LLVM_RELEASE}
3) Use u-a for the libs
4) add rpaths
5) convince people java is evil and have them switch to C

I have a preference for 5), but I suspect Henning would like a different
solution :)

regards,

Koen

Well, what's Fedora or Debian/Ubuntu look like here?

They seem to lack the shark jre, but the 'llvm' package looks like this:

root@dominion:/data/ssd# find /usr/lib | grep llvm | grep Printer | head -n2
/usr/lib/llvm/lib/libLLVMCellSPUAsmPrinter.a
/usr/lib/llvm/lib/libLLVMXCoreAsmPrinter.a

So if we were to follow that option 4) seems to be the way.

Koen

Hi,

our original Idea was, that you can install diffrent llvm versions at the same time. We need
to discuss if we have still the case or really only one version of llvm. If not we can use directly /usr/lib if not
solution 4 with rpath is my favourit. Besides this llvm should go to core, but I wanted to wait
for the 3.0 release and christmas holidays to do it.

Bye Henning

- From the llvm website: "December 1, 2011: LLVM 3.0 is now available for
download!"

FWIW, even after 'fixing' the llvm problems with ln shark still shows some
problems:

root@beaglebone:~/java# javac -O Linpack.java
javac:
/OE/tentacle/build/tmp-angstrom_2010_x-eglibc/work/armv7a-angstrom-linux-gnueabi/llvm2.9-2.9-r0/llvm-2.9/include/llvm/Support/Casting.h:202:
typename llvm::cast_retty<To, From>::ret_type llvm::cast(const Y&) [with X =
llvm::ConstantInt, Y = llvm::Value*, typename llvm::cast_retty<To,
From>::ret_type = llvm::ConstantInt*]: Assertion `isa<X>(Val) && "cast<Ty>()
argument of incompatible type!"' failed.
Stack dump:
