[ECOS] error with __cxa_atexit and __dso_handle

[ECOS] error with __cxa_atexit and __dso_handle

[Santiago Lafon - Controles S.A.]

I want to upgrade my arm-alf toolchan to the latest GNU tools

Some time ago, i made a toolchain with:
     binutils 2.14
     gcc-core 3.3.1
     gcc-g++  3.3.1
     newlib   1.11.0
     insight  5.3

Now i made a new one with
     binutils 2.18
     gcc    4.2.1
     newlib    1.15.0
     insight    6.6

I can build ecos without apparent problems (i'm working with a simple 
eb40a target).

Then, when i try to make a simple application (or if i try to make ecos 
tests), it's when my problems appears.

I get lots of errors like this:

work/eCos/lib/eb40a/rom/eb40a_rom_sin_net_v00.20_install/lib/extras.o: 
In function `__static_initialization_and_destruction_0':
/opt/ecos-snap-2007-09-09/packages/io/fileio/current/src/misc.cxx:105: 
undefined reference to `__cxa_atexit'

/opt/ecos-snap-2007-09-09/packages/io/fileio/current/src/misc.cxx:125: 
undefined reference to `__cxa_atexit'
/opt/ecos-snap-2007-09-09/packages/io/fileio/current/src/misc.cxx:532: 
undefined reference to `__dso_handle'

Could someone help me?

Thanks

The libraries you are using may not be compatible.  Not long ago the
latest version of gcc on x86 would not work (for me) with the latest
version of binutils.  Check the installation notes for gcc.

Hi

The solution is using '--disable-__cxa_atexit' configure option when
you're building gcc. This option is enabled by default in gcc 4.2.1, but
it can be used only with glibc (not with newlib).

Best regards
