 |
|
Hello,
I don't know if this is Desktop, or Programming related; please, move it where it belongs.
I'm trying to emerge fluxbox but the ebuild fails 'cause it calls gcc instead of g++. I've reemerged gcc, glibc, libtool, but nothing helps; so my question is: Is there any way to tell emerge to use g++? I've used:
| Code: | CC="g++" emerge -b fluxbox
CXX="g++" emerge ...
export CC=g++; emerge.... |
but it didn't work.
Also, I'd like to know why this box calls gcc. I have another system which correctly calls g++. If anyone has an idea of what to check, please, drop me a line here.
Thank in advance,
Norberto |

Hmm... try an 'emerge rsync', and if it still acts funky, open up /usr/portage/x11-wm/fluxbox/fluxbox-___.ebuild and see what it's doing.

Ok, I forget to say something. Both systems share /usr/portage thru NFS, so why does one compiles it and the other one, does not? They share the same portage tree....
Thanks,

Are they both the same architecture? How do their make.conf's compare?

Both make.conf are almost identical (same USE flags.) The system that does not compile fluxbox is a K6:
| Code: | CHOST=i586-pc-linux-gnu.
CFLAGS="-march=i586 -O3 -pipe -fomit-frame-pointer" |
The one that compiles it is a P3:
| Code: | CHOST=i686-pc-linux-gnu.
CFLAGS="-march=i686 -O3 -pipe -fomit-frame-pointer" |
BTW, I'm using gcc-2.95.3, glibc 2.2.5. |

YES!! That did it!!
I had to change CXX="gcc" to "CXX=g++" and run env-update. Now I wonder why CXX was set to gcc....
Thank you kram. |

just letting you know that gcc is a front end for ALL the "gnu compiler collection" compilers, it will automatically do C++ compiling for .C .cpp .cxx files etc.
gcc does not stand for gnu C compiler anymore 
so it is actually safe in most cases to just leave that as gcc, (unless it actually fails to detect the correct language).

hmm... gcc version 2 ebuilds set CXX is set to 'gcc' in /etc/env.d/05gcc. gcc version 3 ebuilds set it to 'g++'. can you explain this? on my boxes using profile 1.0 (gcc-2.95.3-r7) i often have to edit ebuilds to set CXX to 'g++', otherwise compiling fails. |
