Re: Errors on x86_64 (broken c++ headers?)

I resubmitted octave to be built yesterday, with more odd results. Everything looks fine for PPC, but for i386, the build appears to have completed, but there is still a failure.log file that says "Build process terminated by timeout". For x86_64, the build failed. Looking at the log file, there are a whole lot of errors that look something like this:

g++ -c -fPIC -I. -I../.. -I../../liboctave -I../../src -I../../libcruft/misc -DHAVE_CONFIG_H -Wall -W -Wshadow -Wcast-align -Wcast-qual -Wpointer-arith -Wwrite-strings -Weffc++ -g -O2 quit.cc -o pic/quit.o

So, the errors appear to be caused by the c++ header files. How is it possible that the header files are broken on one arch and not another? Any other insights into what might have caused this and how to fix it?

There's something weird about mach and C++, I've seen this and some other weirdness just recently myself. The above can be worked around by setting
a suitable CPPFLAGS=-I/usr/include/c++ ... before %configure.


Another oddity I found is that for Wine to build within mach I had to use
LDFLAGS="-lstdc++" %configure - which doesn't make any sense to me either.
