           Summary: 'make tests' fails for linux synthetic target
           Product: eCos
           Version: CVS
          Platform: linux (Linux synthetic target)
        OS/Version: HostOS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: low

I wasn't sure what component to attach this bug to, so I chose other. Feel free
to move it to a more appropriate component, if this is not right.

In setting up the Linux synthetic target for doing some development, I decided
to build all of the ecos tests. Unfortunately, the build errored out with the
following:

$ make tests
...
make -r -C infra/current tests
make[1]: Entering directory `/home/mike/ecos-cvs/synthbuild/infra/current'
gcc -L/home/mike/ecos-cvs/synthbuild/install/lib -Ttarget.ld -o
/home/mike/ecos-cvs/synthbuild/install/tests/infra/current/tests/cxxsupp
tests/cxxsupp.o -g -nostdlib -Wl,-static -Wl,--fatal-warnings
/usr/lib/gcc/i486-linux-gnu/4.4.3/libsupc++.a(cp-demangle.o): In
function `.L644':

make[1]: Leaving directory `/home/mike/ecos-cvs/synthbuild/infra/current'
make: *** [tests] Error 2

The host OS is Ubuntu 10.04.1 LTS. The eCos source is from CVS and was updated
the day of this filing. Here is some other config info from my machine:

# uname -a

Someone else reported that building with gcc-4.3 works. I have not tested that
myself.

__sprintf_chk-140615.patch

This patch indicates one possible route to satisfying the dependency on
__sprintf_chk() within libsupc++ provided by recent linux distributions built
with fortification. The alias need not be weak but it seems less invasive to
declare it as weak. Comments?

__sprintf_chk-140703.patch

A modified patch to provide a non-weak alias. If something else is providing
__sprintf_chk() we should be made aware of it.
