Either comment out the USE_READLINE variable in + src/Makefile.global or install the GNU readline library. + +1.3) [REDHAT] Why do I get problems with missing libdl and dlfcn.h? + + The libdl library is used for dynamic linking of user-supplied + functions at run-time. For some reason this library was missed out + from the Redhat distribution. + + You can obtain the library and the header file from: + + ftp://tsx-11.mit.edu/packages/GCC/ld.so-1.7.14.tar.gz + + Alternatively, you may find precompiled binaries in + distributions/debian/buzz/binary-i386/base/ld.so-1.7.14-4.deb + on the same site, or follow the instructions given for question 1.2 for + correcting the same error with early releases of Slackware 3.1. + +1.4) [SLACKWARE 3.1] Why do I get problems with missing libdl and dlfcn.h? + + See the answer to question 1.1. Slackware up to version 3.0 was + supplied with this library and include file and they seem to be + back in again in the latest versions of 3.1, but the early 3.1 + releases (before 9th September 1996) had them missing and many + CD-ROM versions will have been pressed from the first 3.1 releases. + + The easiest fix is to obtain the file ldso.tgz from the a4 disk of + a more recent Slackware 3.1 distribution and unpack this file + from the root (/) directory, then do + + sh install/doinst.sh + + to complete the installation. Follow this with + + ldconfig + + If you want to install manually, you must first install the file + dlfcn.h in /usr/include. + + Second, install the file libdl.so.1.7.14 (or whatever the latest + release is) in /lib, then do: + + cd /lib + ln -sf libdl.so.1.7.14 libdl.so.1 + ln -sf libdl.so.1 libdl.so + + On some systems (depending on your GCC configuration) it may be + necessary to do: + + cd /usr/lib + ln -sf /lib/libdl.so . + + Finally + + ldconfig + + +1.5) My compile of the backend dies complaining about the include file + dlfcn.h missing + + See the answer to question 1.2. Don't forget that if you are using + an a.out system you must first have installed the dld package + (which is not supplied with most a.out systems) to have dlfcn.h + at all. See Question 1.11. + + +1.6) GCC complains about an ignored option -fpic + + Earlier versions of GCC accepted either -fpic or -fPIC. + It appears that more recent versions (V2.7.2?) require -fPIC. + If you are using an ELF version of Linux, this can safely be + ignored as -fPIC is the default. + + You can correct this by editing + src/mk/port/postgres.mk.linux + + +1.7) I get warnings of the form + warning: cast from pointer to integer of different size + + These can safely be ignored + +1.8) [SuSE-Linux 4.2] Where is curses and termcap? + + SuSE-Linux has ncurses but not curses.

You may need to install + ld.so.x.y.z in /lib and run ldconfig. + + The most recent stable release of the ld package is 1.7.14 + At the time of writing, 1.8.x versions of ld are experimental. + +1.10) Why do I get `yy_flush_buffer undefined' errors? + + This isn't really Linux specific, but is common on older Linux + installations. You must have a recent version of flex (2.5.2 or later) + to compile Postgres95. Note that flex 2.5.3 has a bug: see + Question 3.4. + +1.11) How do I compile Postgres95 on an a.out system? + + First, you must install the dld library.
