Description Grant Edwards 2010-03-16 20:32:40 UTC

After updating from a Decmeber git snapshot to 2010, mtd-utils stopped
building.  Compiles were failing because the compiler couldn't find
include files such as stdint.h.  Examination of the build log revealed
that buildroot's mtd util's make file was passing proper target LDFLAGS
but wasn't passing target CFLAGS.

Thus there was no --sysroot option being passed to gcc, and it couldn't
find its include files.

The attached patch fixes the problem by passing the appropriate CFLAGS
values to make.

It looks like my patch was a week late.  This commit should fix the
problem:

  http://git.buildroot.net/buildroot/commit/?id=d5bf5f967009733da99c55febacb3fb0be686cad

I'll pull the new mtd.mk file and try it.

The current mtd.mk I grabbed from git works.  The commit I mentioned
does fix this bug.
