Developing applications

• the UnixWare 7 Development Kit (UDK) for development of natively-hosted applications for UnixWare 7, and for device drivers

• the Java 2 Development Kit (JDK) for Java applications that can be run on any conforming Java Virtual Machine system (including UNIX, Linux, and Windows)

• the GNU tool chain, including gcc, gdb, and the GNU assembler, to develop applications to be run on Linux, UnixWare 7 and any system that has Linux emulation/simulation capabilities. Two versions are available:

  • A native UnixWare 7 port of the GNU tool chain is included on the Caldera OpenLinux CD. This is based on the GCC 2.95.3 release and uses the native UnixWare 7 libraries, the same linker as is used for the UDK compiler, and the GNU assembler. Manual pages and info files are installed on the system when you install the software.

  • The Caldera OpenLinux GNU tool chain port that is provided as part of the Caldera OpenLinux 3.1 Server or the Caldera OpenLinux 3.1 Workstation. This is based on the GCC 2.95.2 release and uses the glibc libraries, the GNU linker and GNU assembler. See the "OpenLinux Developer Guide" provided through the DocView and KHelpCenter facilities in the Linux environment.

  The native UnixWare 7 port of the GNU toolchain includes the GNU manual pages and info files. The DocView and KHelpCenter documentation on the Caldera OpenLinux 3.1 Developer Workstation, as well as the man and info commands in the Linux environment, provide information about the Linux version of these tools. You can also browse the GNU documentation at http://www.gnu.org/

It is important to note that, when the LKP is installed on your system, statically linked binaries always follow the Linux memory layout for stack, data and text segments.
