Rbconfig not indicating correct ruby-dev libaries locations

Ruby
1

Dear all,

when trying to install the newest Shoes on ubuntu 8.04 from source, I
got an error

shoes build options:
CC = cc
RUBY = /usr/local
OPTIONS =
ruby 1.8.6 (2008-03-03 patchlevel 114) [i686-linux]
CC -o dist/libshoes.so
/usr/bin/ld: cannot find -lruby
collect2: ld returned 1 exit status
make: *** [dist/libshoes.so] Error 1

So the correct ruby development library files cannot be found, even
though they are installed, because
they are named ruby1.8-dev instead of ruby-dev .
Looking at the Makefile, I see this:

RUBY_INCS = ruby -rrbconfig -e 'puts Config::CONFIG["archdir"]'
RUBY_SO = ruby -rrbconfig -e 'puts Config::CONFIG["RUBY_SO_NAME"]'
RUBY_LIBS = ruby -rrbconfig -e 'puts Config::CONFIG["LIBRUBYARG_SHARED"]' -l${RUBY_SO}
RUBY_PREFIX = ruby -rrbconfig -e 'puts Config::CONFIG["prefix"]'

Why can’t Ruby determine the names of these files correctly ?

Thank you very much,

Best regards,

Axel

package managers often completely hose rbconfig since it ends up
reflecting the packager’s machine and not the target machine. this is
extremely true in the case of the one-click-installer and why i
personally always install ruby by hand.

in your case though, you may simply need to set LD_LIBRARY_PATH to
point to the right spot or manage some softlinks so things are found
where they are expected.

cheers.
