Hi, I just downloaded the latest, 8.3.4, and I'm trying to install it on a CentOS 5.2 machine with all the updates (64-bit --- the system is an Opteron DC) The configure script fails reporting it doesn't find readline. The package readline-devel *is* installed, and indeed the .so file is under /usr/lib and /usr/lib64 The problem seems to be with readline dependencies: if I try a dummy program (i.e., a file with a main that says return 0;) and compile it with readline: [ ... ]$ gcc -o tt test.c -lreadline I get the following bunch of errors: gcc -o tt test.c -lreadline /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libreadline.so: undefined reference to `PC' /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libreadline.so: undefined reference to `tgetflag' /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libreadline.so: undefined reference to `tgetent' /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libreadline.so: undefined reference to `UP' /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libreadline.so: undefined reference to `tputs' /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libreadline.so: undefined reference to `tgoto' /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libreadline.so: undefined reference to `tgetnum' /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libreadline.so: undefined reference to `BC' /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libreadline.so: undefined reference to `tgetstr' I know the problem seems to be more a CentOS or RH specific thing, than a PostgreSQL specific one, but I guess someone out here may have run into this, and perhaps have some suggestions? I also tried with libedit (downloaded it from sourceforge, since I could not find RPM packages native to the distribution). Anyway, I get the exact same error --- configure reports the same error, and the little test program, when compiled with -ledit instead of -lreadline, produces almost the same error messages (six of the above lines --- the ones in lowercase, coincidentally) The installation was completed with the switch --without-readline, except that the functionality is somwhat crippled, so I'd much rather avoid the issue. Thanks for any tips/pointers! Carlos --
