The whole point of my question was: opkg's gz_open.c contains the
following code:
============
if (uClinux) {
*pid = vfork();
} else {
*pid = fork();
}
============
IOW, it appears that it was (re)written to run on Linux kernels that
uses vfork() instead of fork() just fine.
So instead of modifying that type of _code_ manually, I'd like to
modify the 2010 Blackfin _toolchain_ so, instead of having the linker
stop dead with an error...
==============
LINK opkg-cl
../libopkg/.libs/libopkg.a(libbb_la-gz_open.o): In function `gz_open':
/usr/src/opkg-read-only/libbb/gz_open.c:67: undefined reference to
`_fork'
==============
... it behave like the 2009 and simply display a warning (instead of
not saying anything, like the 2007 toolchain):
==============
LINK opkg-cl
../libopkg/.libs/libopkg.a(libbb_la-gz_open.o): In function `gz_open':
/usr/src/opkg-read-only/libbb/gz_open.c:67: warning: fork: this
function is not implemented on no-mmu systems
==============
Is this possible to modify AutoConf's configure so that it display a
warning instead of an error when it encounters the use of fork() in an
application that is known to handle it OK like the above?
Thank you.
