Bug#372517: libtool builds non-PIC shared libraries with AC_DISABLE_STATIC and --enable-static
close 372517 thanks Le Samedi 10 Juin 2006 00:48, Ralf Wildenhues a écrit : I have not heard of such behavior before (that I remember), and cannot reproduce it with the test below. Could you show what you did differently to expose this? Ops. My fault. There was an underlying not-so-convenient library that was built with -static in _LDFLAGS then linked into the shared ones.

Bug#372517: libtool builds non-PIC shared libraries with AC_DISABLE_STATIC and --enable-static
Package: libtool
Version: 1.5.22-4
Severity: normal
Hello,
When passing the --enable-static option to the configure script of a
package that has disabled static libraries by default using
AC_DISABLE_STATIC in its configure.ac, both static and *shared*
libraries that libtool builds are non-PIC. Shared libraries should NEVER
EVER be non-PIC.
This is fairly annoying considering that Debian policy recommends that
both shared and static libraries be provided (policy §8.3), and
mandates that shared libraries be PIC (policy §10.2).
Regards,
