Looking into GNU Cp 0.93

I have now built GNU CP 0.93 (on my Linux machine), I used this configure:

.\configure --disable-jni --disable-gtk-peer --disable-gtk-gconf-peer --disable-plugin --disable-core-jni --withour-native-libdir -- with-ecj --host=ppc-amigaos --prefix/home/joakim/amiga/Projekt/cp093 --with-glibj=flat

Which build the whole thing using ecj (could probably use somthing else, but I had that installed), and creates a dir with class-files (not a jar file).

Anyways, trying to use this with JAmiga didn't work, and I believe there are a few native stuff needed. Will continue looking at what is implemented and not; info will come on the wiki.

Roadmap thoughts

I've been thinking of producing a roadmap of some kind. A wiki page has been created. Two subgoals have been identified: getting Java 1.4 working with GNU CP 0.93, and then adding Java 1.5 with GNU CP 0.98.

Making minimal progress

I've been gathering motivation to getting 0.0.6 version out the door. Tonight I played around with the install script, and hopefully we could have version 0.0.6 out soon. That version will contain jamiga 0.0.6 with OS4-specific memory routines, classpath 0.12 and optional jikes.

JAmiga continuing

So, a few things has happened on the JAmiga front.

Began from scratch with the jamiga source found at jamiga.org, and the classpath 0.12. I have made a local SVN to keep track of what I've done.

I've also tried mauve, and ran autoconf aclocal, and what not on my Linux machine, copied that to the Miggy, and made a few changes to the Makefile, so it runs with JAmiga (the CP is separated with ",", since the colon is for devices and disks on Amiga), and "/bin/pwd" was changed to "cd".

So, I'm thinking of releasing a JAmiga 0.0.6, with classpath 0.12 and mauven included, to get a few other testers.

Work now has to been done on:

1. Stabilizing JAmiga

For this the mauven project is excellent, since it doesn't need all classes supported; the first goal would be too make JAmiga crash "nicely" and just throwing exceptions.

2. Getting Java 1.5, 1,6 and 1.7 to run

Done, by either getting GNU classpath 0.98 to run (a few GNU classpath native methods has to be made), OR getting the OpenJDK supported (the former is probably much easier, since I've actually got a 0.98 compiled CP, and only get obvious methods that aren't supported)

3. Improving the org.jamiga-classes

These three steps could be done separately.

The first thing needed though is getting a new JAmiga out the door, getting some buzz, and attracting more testers and developers (and perhaps bounty givers).

Some progress

Yes, I'm making progress on the jamvm for AmigaOS4.

I have found some pthread stuff that isn't implemented on AmigaOS4's implementation. For now its removed with #defines, which ofcourse doesn't work, but I atleast got it to run on the Miggy. I'm thinking of implementing the thread functionality with AmigaOS tasks. For now there are defines, #ifdef __amigaos4__, taking care of special stuff. Perhaps an entire new thread.c for AmigaOS...

Anyhow, I thought it might be good to compile for my x86 aswell, to see how its supposed to work. Then I also got to compile the classpath again.

Its rather encouraging actually being able to run something.

jamvm

Trying to compile jamvm on AmigaOS4.

I have a configure-line:

I also neede to define HAVE_SYS_PARAM_H 0 in src/config.h

#define HAVE_SYS_PARAM_H 0

#define USE_ZIP 0

alphasort had to be included in class.c:

int alphasort(const struct dirent **a, const struct dirent **b) {

return strcmp((*a)->d_name,(*b)->d_name);

}

Don't know if that is correct.

Then a few SIGs wasn't defined.

JamVM for AmigaOS

Trying to compile jamvm for AmigaOS using cross-compiler on Linux.

JamVM-version: 1.5.3

Created a new amiga-directory (should probably be named amigaos4) in src/os, mostly copied from bsd (or was it linux, can't remember). That directory will be made available sometime perhaps.

Made changes in these files to add the amiga directory above:

configure.in

Made ugly hardcoded changes in these files:

USE_MALLOC should be properly defined in some configure files, instead of in the files directly

src/alloc.h

src/alloc.h

added #define sigjmp_buf jmp_bUf:

src/thread.c

src/thread.h

Configure:

./configure --host=ppc-amigaos --program-prefix=/media/disk/Filer/Projekt/amijamvm LIBS="-ldl -lauto -use-dyndl"

Make:

make

Still copmplains about SIG_BLOCK, SIG_UNBLOCK
