can not find jc1 gcj or jvgenmain after gcc install

can not find jc1 gcj or jvgenmain after gcc install

[charfi asma]

Hello,

I have pb with the java fe

I installed gcc 4.4.1 fron source and current gcc version from git ($ git clone 
git://crules.org/git/gcc-dev.git) but in both versions I can not compile java 
files

I looked for the java compiler gcj but I do not find an executable called gcj or 
jc1 (just like g++ or cc1plus for c++ front end)
Is there any configuration option to well install java fe other than 
--enable-languages=java ?

when I compile java file using gcj -save-temps Hello.java --main=Hello -v 2>&1 | 
grep ecj I get an empty .jar

[charfi@is010178 Hello]$ which gcj
which: no gcj in 
(/usr/bin:/bin:/usr/local/bin:/usr/X11R6/bin/:/usr/games:/usr/lib/qt4/bin:/export/home/charfi/bin:/usr/bin)



[charfi@is010178 Hello]$ which g++
/usr/bin/g++

thanks

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

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

Run contrib/download_ecj and rebuild libgcj.

Andrew.

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

[charfi asma]

Hello,

I run the contrib/download_ecj and rebuilt the java fe 

this time I get this new error when calling : /usr/local2/bin/gcj -save-temps 
Hello.java --main=Hello -v 2>&1 | grep ecj

/usr/local2/libexec/gcc/i686-pc-linux-gnu/4.5.1/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
/usr/local2/libexec/gcc/i686-pc-linux-gnu/4.5.1/ecj1: error while loading shared 
libraries: libgcj_bc.so.1: cannot open shared object file: No such file or 
directory

I think that I did not well rebuild the libgcj, can you specify the instructions 
to do that ?

thank you very much

Asma

Try

ldd /usr/local2/libexec/gcc/i686-pc-linux-gnu/4.5.1/ecj1

LD_LIBRARY_PATH problems?  Maybe LD_LIBRARY_PATH doesn't include the
dir that contains libgcj_bc.so.1?

Andrew.

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

[charfi asma]

Hello,

I finally can compile a java file using GCJ ;) thanks Andrew ;)

it was exactly what Andrew said: the LD_LIBRARY_PATH environment variable 
doesn't include the dir that contains libgcj_bc.so.1.
it is even not created, so I added it to other env variables and I added the 
/usr/local2/lib to its value.

but is that normal ?
why should I create alone the variable and specify the path of libgcj_bc.so.1, 
why gcc does not do everything alone when installing it ?

Try

ldd /usr/local2/libexec/gcc/i686-pc-linux-gnu/4.5.1/ecj1

Firstly, please don't top-post on gcc-help.

Yes.

Because you installed gcj in a non-standard place, /usr/local2.  The runtime
linker looks in some standard places, but it does not know where you put
your libraries.

I don't understand this question.

Andrew.
