*libcairo.so is well in /usr/lib/i386-linux-gnu/
* the 'cairo' development package is well installed
I added the path to libcairo.so with the option "-L
/usr/lib/i386-linux-gnu" in the LDFLAGS, thus libcairo.so is well found;
but there is still an error; it looks like an error of the linker
itself, no ?
regards,
Dom
here is the error:
/usr/bin/ld: graph.o: undefined reference to symbol 'cairo_set_source_rgb'
/usr/bin/ld: note: 'cairo_set_source_rgb' is defined in DSO
/usr/lib/i386-linux-gnu/libcairo.so so try adding it to the linker
command line
/usr/lib/i386-linux-gnu/libcairo.so: could not read symbols: Invalid
operation

Subject: error of link during compilation
Hi
I have an error at the end of compilation of my Gtk application given here:
/usr/bin/ld: graph.o: undefined reference to symbol
'cairo_set_source_rgb'
/usr/bin/ld: note: 'cairo_set_source_rgb' is defined in DSO
/usr/lib/gcc/i686-linux-gnu/4.6/../../../i386-linux-gnu/libcairo.so so try
adding it to the linker command line
/usr/lib/gcc/i686-linux-gnu/4.6/../../../i386-linux-gnu/libcairo.so: could not
read symbols: Invalid operation
My project (http://sourceforge.net/projects/seismic-toolkit ) is rather old
(several years), and I never got such error.
I don't know if the error is coming from Gtk, gcc, or linux version; I
upgrade recently to Ubuntu 12.04 LTS, with the new releases of the Gtk project.
Here is the config.log (there is no error during configure):
thank you for any help
Dom
'ld' suggests you what to do:
"
'cairo_set_source_rgb' is defined in DSO /usr/lib/gcc/i686-linux-gnu/4.6/../../../i386-linux-gnu/libcairo.so so try adding it to the linker command line
".
I.e. in your case 'cairo' library is apparently not in 'ld' default search path, it's (if I make "calculations" correctly) under
/usr/lib/i386-linux-gnu/
directory.
Or maybe 'cairo' development package is not installed.
Regards,
Sergei.
