Hi - I'm trying to compile qtruby and I'm having some issues. I have tried both compiling from the kdebindings package AND from the qtruby standalone package and the same error occurs: The compile process always seems to die on an undefined reference to some ruby functions. I'm using Fedora Core 2. This is the last output from make: /bin/sh ../../libtool --silent --mode=link --tag=CXX g++ -Wnon-virtual-dtor -Wno-long-lo ng -Wundef -ansi -D\_XOPEN\_SOURCE=500 -D\_BSD\_SOURCE -Wcast-align -Wconversion -Wchar-subsc ripts -Wall -W -Wpointer-arith -Wwrite-strings -O2 -Wformat-security -Wmissing-format-att ribute -fno-exceptions -fno-check-new -fno-common -o qtrubyinit -module -L/usr/lib -L/ usr/lib/qt-3.3/lib -L/usr/X11R6/lib -version-info 0:0:0 -L../../smoke/qt/ -L/usr/local /lib qtrubyinit.o -lqt-mt -lz -lpng -lz -lm -lXext -lX11 -lSM -lICE -lpthread -Wl,-R -W l,/usr/local/lib -L/usr/local/lib -L. .../../smoke/qt/libsmokeqt.la .../../qtruby/rubylib/ qtruby/libqtrubyinternal.la libtool: link: warning: `-version-info' is ignored for programs qtrubyinit.o(.text+0xa): In function `main': : undefined reference to `ruby\_init' qtrubyinit.o(.text+0x18): In function `main': : undefined reference to `ruby\_script' qtrubyinit.o(.text+0x25): In function `main': : undefined reference to `ruby\_options' qtrubyinit.o(.text+0x2a): In function `main': : undefined reference to `ruby\_run' collect2: ld returned 1 exit status make[3]: \*\*\* [qtrubyinit] Error 1 make[3]: Leaving directory `/home/davp/downloads/kdebindings-050120/qtruby/bin' make[2]: \*\*\* [all-recursive] Error 1 make[2]: Leaving directory `/home/davp/downloads/kdebindings-050120/qtruby' make[1]: \*\*\* [all-recursive] Error 1 make[1]: Leaving directory `/home/davp/downloads/kdebindings-050120' make: \*\*\* [all] Error 2 Any suggestions?

But you shouldn't usually need to use the 'qtrubyinit' command line tool anyway. -- Richard ---

see the following in the other reply:   LIBRUBY =\> libruby.so.1.8.2 detection seems to be wrong i \*think\* there are two possible options that can have the so name and we should probably || the second one just in case the first isn't set. did this in the past but reverted as noone else had the problem. could you revert the revert richard? (hope i commited really can't recall) thanks 馃檪 Alex > **路路路** > > On Jan 22, 2005, at 9:35 AM, Richard Dale wrote: > > > The shared library 'libruby.so' is missing, so you need to build ruby with > > the '--enable-shared' option.

Hi - Even by recompiling Ruby 1.8.2 with --enable-shared, I still have the same problem. Thanks - David
