Error in binutils make for cross compilation

I am trying to compile binutils to set up GNU toolchain for cross compiling for ARM on linux x86 architecture.

For this, I downloaded the GNU toolc开发者_JS百科hain from : http://lejosrt.org/tuto/install-gnu-arm-toolchain-under-linux

This requires a script to be run to install and compile everything. However, on running the script, following error occurs:

I tried upgrading binutils package but in vain.

Any ideas? Thanks in advance.

If you want to just build it and ignore potential problems, put -D_FORTIFY_SOURCE=1 in with your CFLAGS. Since you're using make, it would look something like:

make CFLAGS="«other CFLAGS» -D_FORTIFY_SOURCE=1" «...»

Depending on your project, you could even supply this as a flag to the configure script.

When you build, you'll get a bunch of warnings about redefining this macro, but that's expected.

So what does this flag do? I'm no expert, but it's basically a new feature in recent versions of gcc/glibc that attempts to detect buffer overflows. The default level is "2" (AFAIK), which actually imposes some extra limits above and beyond what the standards dictate. Level "1" is a little less strict.

If you're pedantic, you might like to investigate exactly why your compiler is detecting a buffer overflow. It might be, for example, a call to snprintf where someone's forgotten about the NUL termination behaviour.

(Although: before you go to the trouble, it's quite likely that it's been patched by someone in the upstream project and the fix hasn't trickled through to whatever project you're obtaining this from, so I'd ask the project maintainers about it first.)

For more information, see this RedHat binutils mailing list post.
