[gentoo-catalyst] Setting cflags for a single package in spec file

[gentoo-catalyst] Setting cflags for a single package in spec file

[Garrity, Christopher]

Is there a way to set cflags for just a single package inside the spec
file? I don't need/want to override cflags for all packages, just one.
net-ftp/tftp-hpa-5.1 is causing my netboot2 target to fail because of a
bug related to -O2 and gcc-4.5.3 :(

Not in the spec file directly.

What I would do is set portage_confdir in the spec file, ie
portage_confdir: /directory/containing/etc/portage

And inside your confdir, set CFLAG exceptions as described here:
http://www.gentoo-wiki.info/CflagsExceptions

Let us know if that works for you.

Thanks, that did it!

# grep confdir catalyst-netboot2.spec
portage_confdir: /etc/portage

# find /etc/portage/env -type f -exec cat {} \; -print
CFLAGS="-mtune=core2 -march=core2 -pipe -fomit-frame-pointer"
CHOST="x86_64-pc-linux-gnu"
CXXFLAGS="${CFLAGS}"
/etc/portage/env/net-ftp/tftp-hpa

My tftp client no longer segs :)

Great to hear!

Speaking of which, I don't see any bugs reported in the Gentoo bug
tracker. How can I reproduce the seg fault you're seeing? I just
compiled tftp-hpa-5.1 with gcc-4.5.3-r1.

Thanks,
Matt

does not manifest during compile. tftp <host|ip> -c get foo ... segs on
"get"
