hello!!
I have installed Fedora 9 in Vmware and I tried to run .y file using command yacc -d 123.y which generates y.tab.c file..yacc commnad generates y.tab.c which is correct one..Then I tried gcc y.tab.c -ly but it shows following error...
/usr/bin/ld: cannot find -ly
collect2:ld returned 1 exit status

please help!!

I think .y files are yacc input files and you need to run yacc or bison on it first to generate a .c file that you can then compile with gcc

That error means you either don't have liby(.a|.so) installed or its not in the linker's search path. Try adding -L with the path to where liby.a is
For example:

gcc -c y.tab.c -L/usr/lib -ly

You could always try it without the -ly if that library isn't needed to compile the generated .c file

It should be part of the yacc or bison package (at least it is on debian). Just make sure you have one of those installed correctly.
