Re: [Ltib] Re: Attempting to port netcat 1.84 to PPC

[Stuart Hughes]

Hi John,

I already added this internally (but as netcat).  I didn't want to have
the dependency on glibc2.  I ended up using nc110.tgz (the original).  I
believe this supports UDP.

BTW: LTIB has it's own pkg-config which uses the rootfs prefix so you
should never need to add an PKG_CONFIG_PATHs to spec files. I also
happened to port nc from nc-1.84-16.fc9.src.rpm.  I didn't need to to
anything fancy for pkg-config so long as I select glib2 in the config.

I've attached the 2 srpms generated by my ltib.  I will be merging the
netcat version later on.

Regards, Stuart
