Hello all,

I am trying to install qtruby, but without success. I downloaded  
qtruby-1.0.13 (and I tried some versions prior to this one also), then  
typed

./configure --with-smoke=“qt” --with-qt-dir=/usr/local/qt --prefix=/usr

followed by typing

make

and this is where my problems start:

…  
make[3]: Entering directory `/home/nexa/qtruby-1.0.10/smoke/qt' /bin/sh ../../libtool --silent --tag=CXX --mode=link g++ -Wno-long-long -Wundef -ansi -D_XOPEN_SOURCE=500 -D_BSD_SOURCE -Wcast-align -Wconversion -Wchar-subscripts -Wall -W -Wpointer-arith -O2 -Wformat-security -Wmissing-format-attribute -Wno-non-virtual-dtor -fno-exceptions -fno-check-new -fno-common -o libsmokeqt.la -rpath /usr/lib -version-info 3:4:92 -no-undefined -Wl,--no-undefined -Wl,--allow-shlib-undefined -L/usr/local/qt/lib -L/usr/X11R6/lib smokedata.lo x_1.lo x_2.lo x_3.lo x_4.lo x_5.lo x_6.lo x_7.lo x_8.lo x_9.lo x_10.lo x_11.lo x_12.lo x_13.lo x_14.lo x_15.lo x_16.lo x_17.lo x_18.lo x_19.lo x_20.lo -lqt-mt -lz -lpng -lz -lm -lXext -lX11 -lSM -lICE -lpthread -lGLU -lGL -lX11 libtool: link: AGE`92’ is greater than the current interface number  
`3' libtool: link:`3:4:92’ is not valid version information

I cannot even decipher this error message. I tried to upgrade my  
libtool but that did not solve the problem. I have not found anything  
on this problem, so I guess I must be doing something very wrong. Does  
anybody know what can be causing this?

Thanks for any help!  
Best regards,  
Fredrik
