[Java-gnome-developer] Help me compile a Glade based app natively with GCJ

[Spyros S. <fou...@gm...>]

Hi,
I am trying to compile a simple app, which uses Glade with GCJ (GCC ver.
3.3.5 on SuSE 9.3).
So I type:

gcj -classpath
/usr/share/java/gtk2.4.jar:/usr/share/gnome2.8.jar:/usr/share/java/glade2.8=
.jar
-lgtkjar2.4 -lgnomejar2.8 -lgladejar2.8 --main=3DMain -o Main Main.java

What I get as a result is:

/tmp/ccYlRfbE.o(.text+0x30): In function `main':
ccADRhVT.i: undefined reference to `Main::class$'
collect2: ld returned 1 exit status

I do not have a clue on what to do from that point. It seems like a linker
error (correct me if I am wrong).
Do you have any ideas on what to do?

Thanx in advance,
Spyros "Foucault" Stathopoulos

Spyros,

You're right, this is a linker error. Try adding ':/.' to the end of 
your classpath and see if that helps.

Adam,

Thank you for your answer however, adding :/. to the end of classpath, so
that the command looks like:

gcj -classpath
/usr/share/java/gtk2.4.jar:/usr/share/gnome2.8.jar:/usr/share/java/glade2.8=
.jar:/.
-lgtkjar2.4 -lgnomejar2.8 -lgladejar2.8 --main=3DMain -o Main Main.java
yields the same result again.

/tmp/ccYlRfbE.o(.text+0x30): In function `main':
ccADRhVT.i: undefined reference to `Main::class$'
collect2: ld returned 1 exit status

Most frequently this error occurs because 'Main' is not the fully
qualified name of the class containing the 'main' method.  In this
case it looks like it is though... but just to be sure, does Main.java
have a 'package' statement in it?

Hi, again

I think I've found smth here:
The Main.java class contains the package declaration

package org.test;

When removing it, it seems to compile fine. When put back the linker
produces the same error. Is there a way to keep the package declaration?

Use --main=org.test.Main instead of just --main=Main.  This is a common
error.

... along with forgetting to put the class in a subdirectory matching
its package declaration (Spyros, if you want to keep the package
statement, then Main.java has to be in ./org/test assuming . is on your
classpath)

Hi Anthony,

you were right, I should have used the full path org.test.Main. I should
have thought that it was going to be a stupid mistake.

Thank you (and everybody) for your kind help

Perhaps add . to the classpath (ie. -classpath <blah>:.)?
