If you intend +to really use GNU libc on your system this base directory is /usr. I.e., +you run + configure --prefix=/usr <other_options> + +Some systems like Linux have a filesystem standard which makes a +difference between essential libraries and others. Essential +libraries are placed in /lib because this directory is required to be +located on the same disk partition as /. The /usr subtree might be +found on another partition/disk. + +To install the essential libraries which come with GNU libc in /lib +one must explicitly tell this. Autoconf has no option for this so you +have to use the file where all user supplied additional information +should go in: `configparms' (see the `INSTALL' file). For Linux the +`configparms' file should contain: + +slibdir=/lib +sysconfdir=/etc + +The first line specifies the directory for the essential libraries, +the second line the directory for file which are by tradition placed +in a directory named /etc. + + +~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ Answers were given by: {UD} Ulrich Drepper, <drepper@cygnus.com> |
