Compatibility

Operating systems

Nominal operation
Degraded operations: some functions are unavailable.
Good presumption of good operation: all functions are available, but I do not have any workstation to test.
No opinion. Unsupported architecture but some old releases worked fine.
Unsupported architecture
Compilation failure, work in progress.

RPL/2 is provided as sources files that is compatible with all POSIX-2001 compliant operating systems. I can propose on download page several patches required to build RPL/2 on unsupported systems. These modifications shall not be included in official RPL/2 sources.

This patches policy is not done to start a discussion on benefits of your favorit operating system. It comes from RPL/2 internal design (signals, threads, process, etc.) and some constatations about strange dysfunctions on non POSIX systems (deadlocks, memory leaks...).

•  1 : Process and threads management unavailable due to a bug in sigpending() system call.
•  2 : OpenVMS 8.3 with GNV 2.1-3 and porting library do not provide semaphore access. These functions should be available in future. All utilities in tools directories shall be patched or replaced too. See HP OpenVMS official web site. RPL/2's OpenVMS port has to wait for OpenVMS 8.4.
•  3 : Some intrinsic functions are unavailable, mainly multithreading and multitasking capabilities, as signal handlers do not work as expected on a Posix or SystemV compliant system.
•  4 : RPL/2 seems to perfectly work under XP/Cygwin but I have seen some issues under Seven/Cygwin, specially in process management functions. Please don't fill bug reports as these bugs come from Cygwin functions (kill() and some others return unexpected values).
•  5 : Gnu sed 4.1.2 must replace buggy sed provided by SFU. With GNU sed, automake, autoconf, libtool, gcc-4.4.3 and its dependencies can be built but Interix 3.5 does not provide real POSIX emulation.

Required tools

Compilers

Although the RPL/2 is entirely written out of C and FORTRAN, certain embarked tools require a C++ compiler. The compilers necessary are as follows:

• gcc 4.3 or greater
• g++ 4.3 or greater
• gfortran 4.3 or greater

Source files do not contain any specificity related to gcc compiler. Thus, it is not impossible to build RPL/2 with any other compiler.

awk, gmake

Awk and gmake are required to build RPL/2. RPL/2 cannot be build with regular Unix make tool.

LaTeX 2e, dvips et gv (options)

LaTeX 2e, dvips and gv are optinal but required if you want use printer commands.

MySQL/PostgreSQL (options)

The support of the databases is optional. In the current version, only MySQL type and PostgreSQL databases are accessible through RPL/2.

Reliability

All RPL/2 intrinsic functions are individually tested. In spite of these precautions, the author could not be held responsible for any dysfunction.

Stable versions

All functionalities were carefully tested. These releases should not have particular problems.

Development versions

Development versions are versions whose certain functionalities are either incomplete, or prone to changes. Innovations being able to lead to an instability are accessible only by forcing the configuration using the option --enable-experimental.

Daily tarballs

No guarantee is provided as for the good usability or even compilation of these versions.
