DEVELOPMENT PLATFORMS
|
||
|
|
|
||
|
|
Primary development platform for socat is currently SuSE Linux 8.2 with
|
||
|
|
a 2.4.20 kernel. New features are then ported to the non-Linux platforms on the
|
||
|
|
Sourceforge compile farm (per July 2003: SunOS 5.8 with gcc, and MacOS X 10.2),
|
||
|
|
and AIX 5.1 with gcc. But due to limited time resources and restricted
|
||
|
|
(non-root) access to these systems I cannot extensively test socat there.
|
||
|
|
|
||
|
|
|
||
|
|
PORTING STEPS
|
||
|
|
|
||
|
|
If you want to port socat to another operating system you will typically go
|
||
|
|
through two phases: First, you might just try to compile and run the actual
|
||
|
|
socat distribution (passive phase). Then, you should see if your platform
|
||
|
|
has some nice features that are not yet used in socat, and add code for
|
||
|
|
supporting them (active phase). At last, I encourage you to send me your
|
||
|
|
changes so I can integrate them into the main socat distribution.
|
||
|
|
|
||
|
|
|
||
|
|
PASSIVE PHASE:
|
||
|
|
|
||
|
|
* Generate Makefile and config.h:
|
||
|
|
. If you have gcc, then just invoke "./configure".
|
||
|
|
. If you use another C compiler, configure might not work properly;
|
||
|
|
You will have to adapt config.h and Makefile manually.
|
||
|
|
Change compiler options or defines to use all features of the operating
|
||
|
|
system (not only ANSI-C; e.g. HP-UX: -Ae!)
|
||
|
|
Some practical config.<platform>.h examples have been included in the
|
||
|
|
Config directory of the source that might serve as starting point.
|
||
|
|
|
||
|
|
* Try to "make" socat; correct the errors. If some constants are undefined,
|
||
|
|
please disable these parts option-dependent, not platform-dependent (use
|
||
|
|
#ifdef TCP_OPTION instead of #if MY_OS)
|
||
|
|
|
||
|
|
* If you have big troubles compiling socat then try configure with options
|
||
|
|
--disable-filan --disable-sycls; this excludes some of the most system
|
||
|
|
dependent parts.
|
||
|
|
|
||
|
|
* After successful compilation and linking, run "make test" and try some
|
||
|
|
examples.
|
||
|
|
|
||
|
|
|
||
|
|
ACTIVE PHASE:
|
||
|
|
|
||
|
|
* Check the man pages of your operating system for open(2), fcntl(2),
|
||
|
|
setsockopt(2), ioctl(2), socket(7), ip(7), tcp(7), termios etc. and the
|
||
|
|
include files where you find the definitions of existing options, for new
|
||
|
|
options and implement them - again option-dependent.
|
||
|
|
Places to add code for the new options:
|
||
|
|
. xioopts.h: enum e_optcode (sorted numerically/alphabetically by name)
|
||
|
|
. xio-*.c: select the appropriate address file (e.g., xio-tcp.c for
|
||
|
|
TCP-options) and make a record of type struct optdesc: opt_newoption
|
||
|
|
. xio-*.h: the declation of struct optdesc
|
||
|
|
. xioopts.c: add records to struct optname optionnames for all appropriate
|
||
|
|
names (sorted strictly ASCII for binary search)
|
||
|
|
. filan.c: add the option to the appropriate array (sockopts, ipopts,
|
||
|
|
tcpopts)
|
||
|
|
. socat.html, socat.1, xio.help: write a short documentation and tell which
|
||
|
|
platform and version implements this option
|
||
|
|
|
||
|
|
* problems may occur especially:
|
||
|
|
. with 16 or 64 bit systems
|
||
|
|
. if snprintf() etc. is missing
|
||
|
|
. on UNIX emulations, e.g. Cygwin
|
||
|
|
|
||
|
|
|
||
|
|
INTEGRATION
|
||
|
|
|
||
|
|
* If you ported socat to another platform:
|

|
|
To let other people participate please send the modified files or a patch
|
||
|
|
file and the files generated by ./gatherinfo.sh to socat@dest-unreach.org.
