Notes:

1. to get a more fresh version of JCGO please visit our JCGO development repository (and clone the Git repo or press "Download" button on that site for both "jcgo-lib" and "jcgo-src" tarballs);
2. to get a fresh version of the external BDWGC library please visit BDWGC Git repository;
3. to get a fresh version of the external libatomic_ops library please visit libatomic_ops Git repository;
4. JCGO translates only programs compatible with JDK/J2SE v1.4;
5. to run JCGO, you should download and unpack (to the same above-mentioned location) at least 3 distributive files (jcgo-src-1_XX.tar.bz2, jcgo-lib-1_XX.tar.gz and classpath-0.93.tar.gz);
6. JCGO is a fully Open Source software;
7. Files for downloading are also available at GitHub and Sourceforge sites.

Getting JCGO-SUNAWT (optional component)

The JCGO-SUNAWT re-distributive files:

• jcgo-sunawt-win32-x86-1_00.7z (JCGO-SUNAWT runtime binary re-distributive pack for Windows/x86 target);
• jcgo-sunawt-linux-x86-1_00.tar.gz (JCGO-SUNAWT runtime binary re-distributive pack for GNU Linux/x86 target);
• jcgo-sunawt-solaris-x86-1_00.tar.gz (JCGO-SUNAWT runtime binary re-distributive pack for Solaris SunOS/x86 target).

Prerequisite third-party SDK:

JCGO quick start tips (for Win32)

For those who want to try out JCGO right now without looking into the accompanying documentation, here are the simple steps:

1. Download the core prerequisites:
   • jcgo-lib-1_XX.tar.gz (the JCGO translator itself and the accompanying binary files);
   • jcgo-src-1_XX.tar.bz2 (the sources used during translation);
   • ftp://ftp.gnu.org/gnu/classpath/classpath-0.93.tar.gz
2. Create "C:\JCGO" folder
3. Unpack all the prerequisites to C:\JCGO (preserving the directory structure)
4. Run jcgo.exe (or java -jar jcgo.jar)
5. Try to convert "Hello world" sample to Windows binary (unoptimized):
   • create your "projects" folders (e.g., "C:\MyJcgoProjects") and change the current directory to it;
   • type:

     C:\JCGO\jcgo -sourcepath $~\examples Hello @$~\stdpaths.in

   • invoke the MinGW C compiler (GCC):

     gcc -IC:\JCGO\include -IC:\JCGO\include\boehmgc -IC:\JCGO\native -DJCGO_FFDATA -o hello jcgo_Out\Main.c C:\JCGO\libs\x86\mingw\libgc.a

   • or, alternatively, invoke Visual Studio C/C++ compiler:

     cl -IC:\JCGO\include -IC:\JCGO\include\boehmgc -IC:\JCGO\native -DJCGO_INTNN -DJCGO_FFDATA -DJCGO_WIN32 -D_CRT_SECURE_NO_DEPRECATE -D_CRT_NONSTDC_NO_DEPRECATE jcgo_Out\Main.c C:\JCGO\libs\x86\msvc\gc.lib /link /out:hello.exe

   • run "hello.exe" file
6. View "README" and "FAQ" files.

JCGO quick start tips for Linux/x86 development host

If Linux/x86 is your development host, launch jcgo.jar file on any J2SE v1.4+ VM.

Here are the quick start tips if you choose the Linux version of JCGO:

1. Download the core prerequisites:
   • jcgo-lib-1_XX.tar.gz (the JCGO translator itself and the accompanying binary files);
   • jcgo-src-1_XX.tar.bz2 (the sources used during translation);
   • ftp://ftp.gnu.org/gnu/classpath/classpath-0.93.tar.gz
2. Create "/usr/share/JCGO" folder
3. Unpack all the prerequisites to /usr/share/JCGO (preserving the directory structure)
4. Try to convert "Hello world" sample to a Linux/x86 binary (unoptimized):
   • create your "projects" folders (e.g., "~/MyJcgoProjects") and change the current directory to it;
   • type:

     java -jar /usr/share/JCGO/jcgo.jar -src $~/examples Hello @$~/stdpaths.in

   • invoke the GNU GCC:

     gcc -I /usr/share/JCGO/include -I /usr/share/JCGO/include/boehmgc -I /usr/share/JCGO/native -fwrapv -DJCGO_UNIX -D_IEEEFP_H -DJCGO_UNIFSYS -o hello jcgo_Out/Main.c -lm  /usr/share/JCGO/libs/x86/linux/libgc.a

   • run "./hello" file
