c++ linking probs after gcc 3.0.3 upgrade

c++ linking probs after gcc 3.0.3 upgrade

[Thomas]

ok, i upgraded to gcc 3.0.3, first by compiling from source, and then i got a 
bunch of undefined references to functions and whatnot in iostream.h (endl, 
cout, etc).  then i installed the gcc 3.0.3 slackware package (im running 
slackware 7.1, but ive upgraded it a lot), and now i get all those errors, 
plus undefined references to "__builtin_delete" and the like.  im assuming im 
linking to the wrong librarys or something, but im not sure.  do i have to 
install a new version of libc?  i remember reading the gcc 3.x cant compile 
libc.  i tried doing a "make uninstall" in my source tree, but i get an error 
that that isnt supported in that tree.

if you need more info, just tell me

thanks in advance

I don't know what's the minimum version of glibc you need to build GCC. 
There's a page on the site devoted to all the successful GCC builds, 
pointing to the posts of who managed to do so. So you might have a look if 
there's anything related to Slackware 7.1.
Anyway, I think glibc 2.2.3 or newer will be fine.

ok,  i might try checking what glibc i need.  but the thing is, these 
problems im having dont seem to be related to libc (in my uninformed 
opinion).  i thought that libc was c only, not c++, and all the problems im 
having are with c++ specific things.  even if libc does have c++ functions in 
it __builtin_delete should be a function of a compiler.  isnt it whats added 
to the destructor of a class when you dont explicitly delete a member fo that 
class that you created with new?  so, i guess my question is, is this a libc 
problem or not, and if not, what is it a problem with.  the main reason im 
having problems is i dont really know where to look for something that is 
misconfigured or whatever...

thanks

well, i installed the latest glibc package for slackware, and it worked, so i 
guess that was the problem.  thanks for the help
