[gentoo-dev] impending gcc-config doom

[gentoo-dev] impending gcc-config doom

[Mike Frysinger]

i like the word 'doom', it's neat ... but enough about me, let's talk about 
gcc-config

http://bugs.gentoo.org/show_bug.cgi?id=44731
the next version of gcc-config will be honouring this and gcc itself will no 
longer be exporting CC/CXX via env.d

that means all you people out there who wrote broken ebuilds with the broken 
${CC}/${CXX} syntax are doomed !  convert today to the gcc.eclass and ye 
shall be saved !
sed -i 's:${CC}:$(gcc-getCC):'

${CC:-gcc} is also wrong and will only succeed in making Him smite you

thank you

Is there an equivalent for g++?

Currently media-gfx/sam2p uses
CXX="$(gcc-config -B)/g++"
but presumably there's a better way.

Perhaps changing flag-o-matic accordingly would be a good idea?	

Just wondering,

flag-o-matic has nothing to do with this, these arent flags

use gcc.eclass (man gcc.eclass) or use the new toolchain-functions.eclass (no 
documentation yet, PHEAR IT)

ugh, that is horribly wrong ;)
the correct method is:
inherit gcc
CXX="$(gcc-getCXX)"

or (since we're moving away from gcc.eclass):
inherit toolchain-functions
CXX="$(tc-getCXX)"

$ grep -n '${CC' /usr/portage/eclass/flag-o-matic.eclass

267:    local cc=${CC:-gcc} ; cc=${cc%% *}
276:    local cc=${CC:-gcc} ; cc=${cc%% *}
350:    ${CC/ .*/} -m64 -o /dev/null ${temp}.c > /dev/null 2>&1

Looks exactly like what you said shouldn't be done, doesn't it?

Bye, Patrick

ah yes, good catch ... i thought you were saying the functions should be added 
to flag-o-matic, not that flag-o-matic was broken
thanks :)
