Looks like the relevant error in the log is:

:info:build Undefined symbols:
:info:build   "_libedit_getline", referenced from:
:info:build       _el_source in el.o
:info:build       _history_w in history.o

:info:build ld: symbol(s) not found

Getline appears to be unavailable until 10.7 or later.

I ran into a similar error with a different port using PPC on MacOSX 10.4 and fixed it successfully using the information here: <​http://forums.macrumors.com/threads/unable-to-compile-c-program-with-getline-using-gcc.1308709/>, which sends you ultimately here < ​http://opensource.apple.com//source/cvs/cvs-42/cvs/lib/> for the missing functions.

There are two files, getline.c and getdelim.c, and their headers in that directory, that provide the missing functions.

You could try to modify history.c, historyn.c, and probably el.c to add in those functions, and see where that takes you.

Good luck!

There is also this fix <​https://trac.macports.org/browser/trunk/dports/textproc/uni2ascii/files/patch-ascii2uni.c.diff?rev=73852> for a similar error.

You could try to modify history.c, historyn.c, and probably el.c to add in those functions, and see where that takes you.

Thanks a lot. I'll modify el.c and el.h, then have a test.

I just try to install libedit again to see where el.c and el.h is, but the errors gone. This time the archive fetched from "​http://cjj.kr.distfiles.macports.org/libedit", and last time the archive fetched from "​http://thrysoee.dk/editline/".

I note there is an official getline replacement in the port now, added 4 days ago. It must have been rolling out when you first tried your build.

It's OK. Thanks!

So I guess r149803 fixed this.
