Hello all,
I've built the above cross-compiler and ran the GCC testsuite.
Noted a lot of c++ tests failed with the same output:
...
terminate called after throwing an instance of 'int'
terminate called recursively
Are you configuring cross glibc with --disable-libunwind-exceptions?
This has been necessary for all ARM EABI cross-compilers I've built so far.
Yes, I've tried this too, without success.
Just of curiosity, I tried the exact prerelease version the
http://gcc.gnu.org/ml/gcc-testresults/2007-09/msg00570.html
was using for test - it failed too.
I suppose the problem is in Gcc.
Could someone having the 4.2 release series compiler configured for
ARM EABI target try this simple test:
I just tried it with the native Debian ARM EABI compiler: gcc-4.2.4,
binutils-2.18.0.20080103, glibc-2.7 and it silently exits(0).
I tried gcc-4.2.4-glibc-2.6 and glibc-2.7, with no avail.
I suppose the Debian version of 4.2.4 has its own set of patches.
Also, the combination of latest tools make it work:
gcc-4.3.2-glibc-2.7-binutils-2.18.
FWIW, their g++-4.2 is also configured with explicit
--disable-sjlj-exceptions, although that seems to be the default.
Yes, it is disabled by default.
Thanks a lot!
