As others have already pointed out, there are no shortcuts to the righthand side of the learning curve. For most apps, the usual "configure; make; make install" works. It's when it doesn't that you need to be able to draw on the kind of experience that puts you on the righthand side of the curve. In some cases, you really do need to be able to debug and write some code yourself. Apps written in Python or Perl tend to port fairly easily, because the folks who have ported the languages and their main libraries have already done most of the hard work. C and C++ apps, on the other hand, are more likely to surface differences in the Linux and FreeBSD API's. If you're porting one of those, you need to be willing and able to dig in and research those APIs. For a good grounding in the UNIX API's, I'd recommend the Stevens/Rago book "Advanced Programming in the UNIX Environment". The Avoiding Linuxisms article also has a lot of useful information. The Porter's Handbook contains most of what you'll need to know once you've got the app built and running OK and you want to add it to the portstree. (I say "most" because you'll still need to have some profiency with BSD makefiles, and the Handbook doesn't teach you that.) ___ freebsd-ports@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ports To unsubscribe, send any mail to "freebsd-ports-unsubscr...@freebsd.org"

Right :-) Chetan, First check if the port already exists http://www.freebsd.org/ports/ If no money: - A few years academic study helps - Obtain source code, check licence. - Read sources. - Read relevant FreeBSD manuals & documentation - Work. - If stuck, post exact questions to lists specific to whatever aspect. - Feed code extensions back to generic source owner. - Use send-pr to give us a working ports/ wrapper.

Re: porting: Linux to Freebsd
Or you could simply start at step 3, then for every problem you have in step 4, Google it. For the problems you cannot fix that way, ask (smart) questions on the appropriate FreeBSD mailing lists, until the application compiles. Then continue to step 5. Note: the learning curve will be steep, take the time needed to make it.

Quick try:

No change here either.
Obvious question but if you edited configure.ac, you did remember to
rerun autoconf afterwards didn't you? Can you post the configure
script?
Note that your problems with configure do not surprise me. Despite
claims otherwise, it appears to have been designed (using the word
very loosely) as a tool to impede application portability.
I beg to differ on "impede". It's a tool, as you're writing, and as such,
it can only be as powerful as its operator. Programmers using non-portable
shell code are subverting the tool, not using it.
Operating systems also have their share there. For instance, all too many
FreeBSD system header files are _not_ standalone, but have undocumented
dependencies on other headers, even if that runs counter to IEEE Std.
1003.1 (aka Single Unix Specification or POSIX). While such bugs are
easily fixed, it's often hard for the learning porter to do...
So rather than spraying non-helpful comments over the thread (if you have
issues with autoconf, file bug reports or contribute to make autoconf - or
another tool you deem more suitable - better).

Uh ... no. (When I said "complete novice", wasn't kidding. :-)

Ran autoconf(-2.62).
That seems to have fixed the "configure" stage.
I'm into compilation, and:
/usr/include/malloc.h:3:2: error: #error " has been

You didn't provide enough info. There should have been a line or two
more which referenced files in the src of what you want to compile. In
those places you have to replace the '#include ' with
'#include '.

Some possibilities:
- In the test for byacc they maybe forgot quotes to protect an
empty value.
- wrong operator used in test
- unknown bashism
Right: I re-ran under bash, and got the same problems.
Looking at configure.ac, I see:
AC_PATH_PROG(YACC,byacc,no)
if test "x$YACC" == "xno"
This should be a "=", not a "==".
Looks like bashism. Someone tries to substitute something in CFLAGS,
but this kind of advanced substitution is not supported in a posix
compliant sh. You can test this assumption by installing bash and
runnging "bash ./configure" instead. If it is true, you need to fix
configure.in or configure.ac.
Relevant bit is:
for ac_remove_CFLAG in "-O1" "-O2" "-O3" ; do
CFLAGS=${CFLAGS//${ac_remove_CFLAG}/}

That's an extremely open-ended question. Probably the biggest issue is the use of GNU extensions in system utilities - particularly the assumption that /bin/sh is bash. You would probably be better off asking specific questions on problems that you run into. -- Peter Jeremy pgpKgMCicra7N.pgp Description: PGP signature
Re: porting: Linux to Freebsd
Quoting Robert Huff (from Mon, 8 Jun 2009 01:01:32 -0400): Is there anyone out there with experience porting from Linux to FreeBSD and/or writing code for both who can spare a few cycles to help a complete novice figure out what's different (and how to fix it)? Have a look at http://wiki.freebsd.org/AvoidingLinuxisms for some generic advise. Feel free to propose things to add there (or add them yourself, we hand out write access upon request). If you do not know how to port a specific part of an application to FreeBSD, feel free to ask here (or on a more specific ML, e.g. if it is network related, the network ML of FreeBSD is maybe better suited).

porting: Linux to Freebsd
Is there anyone out there with experience porting from Linux to FreeBSD and/or writing code for both who can spare a few cycles to help a complete novice figure out what's different (and how to fix it)?
