[gentoo-user] cxx/nocxx error building gcc-4.5.3-r1

[gentoo-user] cxx/nocxx error building gcc-4.5.3-r1

[Walter Dnes]

  I'm doing a fresh 32-bit install on an older Dell with an AMD K8, for
experimentation.  I'm getting a build failure on gcc as listed below.  I
start off my USE variable with "-*" and then add on stuff as necessary.
A Google search turned up
http://www.gossamer-threads.com/lists/gentoo/dev/242446 where vapier
says...

  That appears to be relavant to me.  But I'm not a developer, and I
don't claim to totally understand what he's talking about.  I do have
some ebuilds that use C++.  Should I add "cxx" to my USE variable?  The
build error message follows...

Hi,

since you have not posted your specific USE-flags, it gets harder to
help you. I think you could try to add cxx to your USE-flags.
If the does not help you, you should post your USE-flags and
eventually the output of emerge --info to make it easier for us to
help you.

regards

Just for clarification:
- -* means -cxx and -nocxx
This can produce the failure you get. Therefore you should set cxx
(normally you should want a c++ compiler).
If you have "-* cxx nocxx ...." you will have to remove one of the two
useflags.

  Thanks.  It builds now, with "cxx" added to USE.
