bubblestrap on the 3.4 branch?

[Christian Joensson]

Hi...

Is there something special I need to do on to run bubblestrap on the 3.4 branch?

I get into this problem:

configure: loading cache ./config.cache
configure: error: `LDFLAGS' was not set in the previous run
configure: error: changes in the environment can compromise the build
configure: error: run `make distclean' and/or `rm ./config.cache' and start over
make[1]: *** [config.status] Error 1
make[1]: Leaving directory `/usr/local/src/branch/objdir.3.4/gcc'
make: *** [bootstrap] Error 2

I surely don't want to run make distclean... so, I'll try rm
.config.cache and see what happens...

If you have any help, pls let me know.

This happens sometimes because recursive configure invocations can have 
different variables set than recursive make invocations causing slightly 
different config.cache files to be created depending on how exactly 
configure was invoked in a subdirectory.  So if you configure, cvs 
update, and then type make forcing a recursive make to invoke configure 
in a subdir previously configured via a recursive configure, you may get 
an error.  Just delete the subdir config.cache file and type make again.

Some patches have been added to gcc-4 to try to fix this, though new 
errors in this area sometimes creep back in.
