Dear All, I had a problem on installing Tcl/Tk 8.0.4 or 8.0.5 on Sun Ultra 30, Solaris 2.6. First I go to "unix" subdirectory and run ./configure --enable-gcc (otherwise cross-compiling error). Then run ./make which fails as follows: make: *** [regexp.o] Error 1 Any hint is highly appreciated. Dapeng
