cross gcj-compile and libgcj.spec for arm

Asked by Ja9

How do I run or configure the arm cross gcj compiler on an 1386 system?

I installed the arm-linux gcj-4.9-arm-linux-gnueabi packages.
when I run the binary with option -v give:

/usr/bin/arm-linux-gnueabi-gcj-4.9 -v

Using built-in specs.
Reading specs from libgcj.spec
arm-linux-gnueabi-gcj-4.9: error: libgcj.spec: No such file or directory

---------------------------------------------------------------
I think I miss the cross libgcj libraries for the cross-compilation.

Because the host gcj is running as it should:

gcj -v

gives

Using built-in specs.

rename spec startfile to startfileorig
rename spec lib to liborig

What Ubuntu release are you running (uname -a ; lsb_release -crid)?
How did you install that package?

This is the release I am running:
uname -a
Linux ubuntu 3.18.0-13-generic #14-Ubuntu SMP Fri Feb 6 09:56:10 UTC 2015 i686 i686 i686 GNU/Linux

lsb_release -crid
Distributor ID: Ubuntu
Description: Ubuntu Vivid Vervet (development branch)
Release: 15.04
Codename: vivid

I installed the package with:
sudo apt-get install gcj-4.9-arm-linux-gnueabi

I hope this information helps to give me a hint.

Ubuntu 15.04 is currently in development. Official release date will be in two months' time. You cannot expect that it already complete and error-free.

It seems that a package with the files that you are looking for does not exist (yet).

There is a bug report in Debian with a similar problem (or at least looks similar to me) https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=766619
So it seems that there is still some work to be done for providing a complete gcj-arm-linux-gnueabi cross compiling environment.

Thanks!

Now I now that it's not me doing something wore, but that there is still some work to be done for the ubuntu guys to provide the complete gcj-arm-linux-gnueabi cross compiling environment.

I hope they can manage it before the Beta release.

Can you help with this problem?
