Re : can not find jc1 gcj or jvgenmain after gcc install

[charfi asma <charfiasma at yahoo dot fr>]

Hello,

this is exactly what I did to compile Hello.java using GCJ 

1. downlad a release from the GCC web site: 
2. extract the bz2 file :   # tar -xvjf gcc-4.5.1.tar.bz2
3.  sh ./download_prerequisites  after downlowd from   
http://gcc.gnu.org/svn/gcc/trunk/contrib/download_prerequisites 

4. # mkdir build_java
5. # cd build_java/
6. # ../gcc-4.5.1/configure --enable-languages=c,c++,java --prefix=/usr/local2
7. # make
8. # make install
9. # /usr/local2/bin/gcj -save-temps Hello.java --main=Hello -v 2>&1 | grep ecj

and I get this error:

ecj1 Hello.java -g1 -fbootclasspath=./:/usr/local2/share/java/libgcj-4.5.1.jar 
-g1 -fsource=1.5 -ftarget=1.5 -fzip-dependency Hello.zip -fzip-target Hello.jar
gcj: error trying to exec 'ecj1': execvp: Aucun fichier ou dossier de ce type

info about my platform:

# uname -a
Linux is010178 2.6.31.6-server-1mnb #1 SMP Tue Dec 8 16:48:07 EST 2009 i686 
Intel(R) Core(TM)2 Duo CPU     P8400  @ 2.26GHz GNU/Linux

Thanks

Asma

You need to tell us exactly what you did.  What commands, configure args,
and so on, so that someone can duplicate what you did.
