Compiling QtRuby


#1

I’ve been trying to compile Qt Ruby without success.
I’ve got Qt 4.1.1 installed and it tested fine. I was able to run the
demos without a problem.

When I try to compile qt4-qtruby-1.4.3 I get this:

-c -o qtrubyinit.o `test -f 'qtrubyinit.cpp' || echo './'`qtrubyinit.cpp; \ then mv ".deps/qtrubyinit.Tpo" ".deps/qtrubyinit.Po"; \ else rm -f ".deps/qtrubyinit.Tpo"; exit 1; \ fi /bin/sh ../../libtool --silent --mode=link g++ -Wnon-virtual-dtor -Wno-long-long -Wundef -ansi -D_XOPEN_SOURCE=500 -D_BSD_SOURCE -Wcast-align -Wconversion -Wchar-subscripts -Wall -W -Wpointer-arith -O2 -g -O2 -Wformat-security -Wmissing-format-attribute -fno-exceptions -fno-check-new -fno-common -o qtrubyinit -module -L/usr/local/Trolltech/Qt-4.1.1/lib -L/usr/X11R6/lib -version-info 0:0:0 -L../../smoke/qt/ -L/usr/local/lib qtrubyinit.o -lQtGui -lz -lpng -lz -lm -lXext -lX11 -lSM -lICE -lpthread -Wl,-R -Wl,/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: In function `main': /source/qt4-qtruby-1.4.3/qtruby/bin/qtrubyinit.cpp:25: undefined reference to `ruby_init' /source/qt4-qtruby-1.4.3/qtruby/bin/qtrubyinit.cpp:26: undefined reference to `ruby_script' /source/qt4-qtruby-1.4.3/qtruby/bin/qtrubyinit.cpp:27: undefined reference to `ruby_options' /source/qt4-qtruby-1.4.3/qtruby/bin/qtrubyinit.cpp:28: undefined reference to `ruby_run' collect2: ld returned 1 exit status make[3]: *** [qtrubyinit] Error 1 make[3]: Leaving directory `/source/qt4-qtruby-1.4.3/qtruby/bin' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/source/qt4-qtruby-1.4.3/qtruby' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/source/qt4-qtruby-1.4.3' make: *** [all] Error 2

I know almost nothing about compiling C++ programs, does anyone know how
I can get around this problem.

Thank you.

A question from a non-Qt user. Does Qt Ruby try to match version
numbers with Qt. For example is qt-qtruby-1.4.3 meant to be used with
any qt-1.4.x ?

Was your compilation from a *.tar.gz file? or did it come from
installing a *.gem file?
