Hi, I have successfully managed to build Ruby 1.8.6 on HP-UX, but when using irb it crashes when the cursor keys or escape keys are used. I believe that I need to rebuild Ruby with readline support enabled. In order to do this, I downloaded the gnu readline source and built and installed that to $HOME/lib (I don’t have access to write to /usr/lib): export CC=“cc –Ae” ./configure --prefix=$HOME make make install This worked fine. Next, I configured the build process to include readline support: export CC=“cc -Ae” ./configure --prefix=/home/host/ruby-1.8.6 --with-readline-dir=$HOME Then ran make. It when compiling readline failed with the following error: compiling readline ``` cc -Ae -I. -I../.. -I../../. -I../.././ext/readline ``` -DHAVE\_READLINE\_READLINE\_H -DHAVE\_READLINE\_HISTORY\_H -DHAVE\_RL\_FILENAME\_COMPLETION\_FUNCTION -DHAVE\_RL\_USERNAME\_COMPLETION\_FUNCTION -DHAVE\_RL\_COMPLETION\_MATCHES -DHAVE\_RL\_DEPREP\_TERM\_FUNCTION -DHAVE\_RL\_COMPLETION\_APPEND\_CHARACTER -DHAVE\_RL\_BASIC\_WORD\_BREAK\_CHARACTERS -DHAVE\_RL\_COMPLETER\_WORD\_BREAK\_CHARACTERS -DHAVE\_RL\_BASIC\_QUOTE\_CHARACTERS -DHAVE\_RL\_COMPLETER\_QUOTE\_CHARACTERS -DHAVE\_RL\_FILENAME\_QUOTE\_CHARACTERS -DHAVE\_RL\_ATTEMPTED\_COMPLETION\_OVER -DHAVE\_RL\_LIBRARY\_VERSION -DHAVE\_RL\_EVENT\_HOOK -DHAVE\_RL\_CLEANUP\_AFTER\_SIGNAL -DHAVE\_RL\_CLEAR\_SIGNALS -DHAVE\_RL\_VI\_EDITING\_MODE -DHAVE\_RL\_EMACS\_EDITING\_MODE -DHAVE\_RL\_CLEAR\_SIGNALS -DHAVE\_REPLACE\_HISTORY\_ENTRY -DHAVE\_REMOVE\_HISTORY -I/home/host/include +Z -g -c readline.c ``` ld -b -E -L"../.." -L"/home/host/lib" -o ``` …/…/.ext/hppa2.0w-hpux11.11/readline.sl readline.o -lreadline -ltermcap -ldld -lcrypt -lm -lc ld: Invalid loader fixup in text space needed in output file for symbol “$00000035” in input file: “/home/host/lib/libreadline.a(bind.o)”.

So I tried to build ruby again export CC=“cc -Ae +Z” ./configure --prefix=/home/host/ruby-1.8.6 --with-readline-dir=$HOME This time, similar error, but complaining about /usr/lib/libtermcap.a. compiling readline ``` ld -b -E -L"../.." -L"/home/host/lib" -o ``` …/…/.ext/hppa2.0w-hpux11.11/readline.sl readline.o -lreadline -ltermcap -ldld -lcrypt -lm -lc ld: Invalid loader fixup in text space needed in output file for symbol “$00000008” in input file: “/usr/lib/libtermcap.a(tparm.o)”. Make sure it was compiled with +z/+Z. \*\*\* Error exit code 1 Stop. \*\*\* Error exit code 1 Stop. Unfortunately I do not have access to /usr/lib/libtermcap.a and can’t rebuild it. Can anybody offer any advice? Am I on the right track in thinking that the IRB problems are to do with readline support, or have I gone about this completely wrong? Thanks, Stu ---

For what it’s worth, I found some threads that discussed building Ruby and then applying ReadLine afterwards, though it doesn’t seem to do anything for me… host@titan:/home/host/ruby-1.8.6-src/ruby-1.8.6/ cd ext/readline host@titan:/home/host/ruby-1.8.6-src/ruby-1.8.6/ext/readline/ ruby extconf.rb checking for tgetnum() in -lncurses… no checking for tgetnum() in -ltermcap… yes checking for readline/readline.h… no checking for editline/readline.h… no host@titan:/home/host/ruby-1.8.6-src/ruby-1.8.6/ext/readline/ make host@titan:/home/host/ruby-1.8.6-src/ruby-1.8.6/ext/readline/ make clean host@titan:/home/host/ruby-1.8.6-src/ruby-1.8.6/ext/readline/ make host@titan:/home/host/ruby-1.8.6-src/ruby-1.8.6/ext/readline/ make install host@titan:/home/host/ruby-1.8.6-src/ruby-1.8.6/ext/readline/ ll -rt total 400 -rw-r–r-- 1 host staff 79 Feb 12 2007 depend -rw-r–r-- 1 host staff 1162 Feb 12 2007 README -rw-r–r-- 1 host staff 20738 Feb 12 2007 readline.c -rw-r–r-- 1 host staff 1233 Feb 12 2007 README.ja -rw-r–r-- 1 host staff 1993 Feb 12 2007 extconf.rb -rw-rw-r-- 1 host staff 130412 Oct 17 12:34 readline.o -rw-rw-r-- 1 host staff 1988 Oct 17 12:58 Makefile -rw-rw-r-- 1 host staff 2885 Oct 17 17:28 mkmf.log host@titan:/home/host/ruby-1.8.6-src/ruby-1.8.6/ext/readline/
