Hi,
I am trying to port gcj to RTEMS now and have got boehm-gc, libffi,
libjava compiled for RTEMS. But when I try to use i386-rtems-gcj to
compile HelloWorld for RTEMS after install, I got "error trying to
exec 'ecj1': execvp: No such file or directory" and don't know how to
fix it. Could somebody give me an help hand or an advice ? Very
Thanks.
The error information can be seen below:

Did you supply the build with an ecj.jar? contrib/download_ecj will obtain one
for you. ecj1 is a natively compiled ecj binary used by gcj to compile Java
source code to bytecode:
$ file /home/andrew/build/gcj/libexec/gcc/x86_64-unknown-linux-gnu/4.6.0/ecj1
/home/andrew/build/gcj/libexec/gcc/x86_64-unknown-linux-gnu/4.6.0/ecj1: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.9, not stripped

Thank you very much, Andrew. :)
I have got my cross ecj1 under your help.
[rtems@localhost libjava]$ file
/mnt/gcj/mytoolchain/libexec/gcc/i386-rtems/4.7.0/ecj1
/mnt/gcj/mytoolchain/libexec/gcc/i386-rtems/4.7.0/ecj1: ELF 32-bit LSB
executable, Intel 80386, version 1 (SYSV), dynamically linked (uses
shared libs), for GNU/Linux 2.6.32, not stripped
But when I run this ecj1, an error occurred:
[rtems@localhost libjava]$
/mnt/gcj/mytoolchain/libexec/gcc/i386-rtems/4.7.0/ecj1
Exception in thread "main" java.lang.NoClassDefFoundError:
org.eclipse.jdt.internal.compiler.batch.GCCMain
at gnu.java.lang.MainThread.run(libgcj.so.11)
Caused by: java.lang.ClassNotFoundException:
org.eclipse.jdt.internal.compiler.batch.GCCMain not found in
gnu.gcj.runtime.SystemClassLoader{urls=[file:./],
parent=gnu.gcj.runtime.ExtensionClassLoader{urls=[], parent=null}}
at java.net.URLClassLoader.findClass(libgcj.so.11)
at gnu.gcj.runtime.SystemClassLoader.findClass(libgcj.so.11)
at java.lang.ClassLoader.loadClass(libgcj.so.11)
at java.lang.ClassLoader.loadClass(libgcj.so.11)
at gnu.java.lang.MainThread.run(libgcj.so.11)
While the local ecj1 is running well :
[rtems@localhost test]$ /usr/libexec/gcc/i686-redhat-linux/4.5.1/ecj1
[rtems@localhost test]$
Is there someone who has encountered the same question? Any reply will
be welcome.
Best Regards,
Jie

Hi,
This problem is fixed by
