Usage of shared libraries

[Jate Sujjavanich]

I am presently using the Sourcery G++ Lite 4.2-8 toolchain (uclinux). It
is compatible with my circa 2005 uClinux-dist and most applications work
well with the shared uClibc.

What I am trying to do now is create a "hello world" shared library.
Using options as recommended on uCdot.org creates a library of size
mshared-library-id * 16 MB. I am looking for the new recommended way of
creating one for this toolchain.

I am also having some issues with an application that is threaded using
pthreads. It seems that the errno is not being passed from the kernel to
the uClibc side of the system call. In my case, the mkfifo (mknod) does
return a -1, but the errno on the application side is always a 0. I have
a feeling this may be fixed in the latest uClibc. Does anyone know?
