Some more information on this crash will be very helpful. What
exactly do you see?

You can install them anywhere, they don't have to be in /usr. You can
for instance put them in /mytoolchain or whatever. Then just put
/mytoolchain/bin in your PATH, and execute
x86_64-pc-mingw32-(toolname) as you have done.
If you're using cygwin, you need to use the same version as the
cygwint hat you have. I think cygwin updated their runtime dll to a
version newer that 1.5.25-12, which is what that particular version
you downloaded is compiled against.
The crash is very quiet.
I have this:
for ( int r = 1; r < 10; ++r )
{
float rrate = r * 10.0F;
std::cout << std::endl;
std::cout << " Rain rate = " << rrate << " mm/hr" << std::endl;
}
The output is:
-----------------------------------
Rain rate =
-----------------------------------
without a newline at the end. It bombs at outputting the float. No messages
are put out.
Now I'm trying to download and build the tool chain from svn with a script.
When I run this makebuildroot.sh it starts with a cvs download of binutils. It
times out. Now it's been a while since I've used cvs and I never dug into it
that much anyway. Is there anything I need to set up for this?
I'm hoping that a bootstrap of everything into some build directory would get
past any version inconsistencies.
Thanks,
Ed
