Synopsis: errno_location() not linked when creating static library
State-Changed-From-To: open->closed
State-Changed-By: rodrigc
State-Changed-When: Fri Nov 16 21:14:02 2001
State-Changed-Why:
This is not a GCC problem. errno_location is defined
in the GNU C library that comes with Linux.
If you want errno_location to be defined in your code,
then in your source, include
#include <errno.h>
And when you link make sure to add -lpthread,
since the symbol for errno_location is defined
in the libpthread library on Linux.
This is not a gcc problem.

(Red Hat Linux 7.1 3.0.1-3) and
(hppa1.1-hp-hpux11.00)
the linux configure setup:
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --disable-checking --host=i386-redhat-linux
>Description:
Creating static libraries the *errno_location() is not
declared. This is a problem when loading the shared libraries
into TCL because it wants everything defined :
libddftcl.so: undefined symbol: _Z16__errno_locationv
where libddftcl.so is the shared library
linked by
g++ -shared *.lo -Wl,--whole-archive *.al *.a -Wl,-soname -Wl,libddftcl.so.0 -o .libs/libddftcl.so.0.0.0
>How-To-Repeat:
create shared libraries and try to load them in tcl or
evaluate if errno_location is defined
>Fix:
define errno_location when building shared libraries
