Hello Peter,
Been a long time since we communicated on this issue. I wasn't able to
look into the Kaffe Custom Edition for some time. But this is what I have
been able to do in the last few days.
I read thru the whole structure of Kaffe.
This is what I have done.
kaffe-19990929 untarred in the following
/root/kaffe-19990929
|
|--------+ build-gnu
|
|
|--------+ build-smx-vc++
|
|
|---------+ build-win32-vc++
|
|
|---------+ build-wince-vc++
|
|
|---------+ src
Did the necessary modification to the Makefile in
/root/kaffe-19990929/build-gnu/libraries/clib/awt
so that Kaffe uses the framebuffer instead of X11.(Please have a look at
the Makefile attachement). For this, I have installed the GRX2.3 graphics
library. The test progs of GRX works just fine and also the REGRESSION in
kaffe works fine. But when I run a simple AWT based application it give
the following ERROR. I have attached the AFrame.java file also.
[root@fobar awt]# kaffe AFrame
java.lang.ExceptionInInitializerError: [exception was
java.lang.ExceptionInInitializerError: [exception was
java.lang.ExceptionInInitializerError: [exception was
java.lang.ExceptionInInitializerError: [exception was
java.lang.UnsatisfiedLinkError: awt]]]]
at AFrame.main(12)
Could you point out as to where I have goofed up?
Awaiting reply...please reply asap as I will be going on my one month
vacation and need to produce some kind of result before that.
Wish you a Merry X'mas.
Rgds,
Ganesh.
