Re: error of link during compilation

 *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
