There's the problem. You'll need to set the value of the LD_YACC environment variable to something that the linker/loader will interpret as a reference to a yacc-like library. For example: $ make distclean ... $ rm -f config.cache $ export LD_YACC="-L /usr/local/lib -lbison" $ ./configure &>configure.log ... The exact value for the LD_YACC environment variable will depend on the location of the library and whether you choose to use bison or byacc. Regards, Steve Emmerson <http://www.unidata.ucar.edu>
