Description

Error : "In file included from ../../../../aspectator/libgcc/../gcc/unwind-dw2.c:333:0:
../../../../aspectator/libgcc/../gcc/config/i386/linux-unwind.h: In function 'x86_fallback_frame_state':

It's a well known issue between old gcc and new glibc at different architectures: http://gcc.gnu.org/ml/gcc-patches/2012-03/msg01073.html.

As a temporary workaround it is proposed to patch gcc/config/i386/linux-unwind.h (that you can found in "ri" directory of LDV tools sources):

diff --git a/libgcc/config/i386/linux-unwind.h b/libgcc/config/i386/linux-unwind.h

Maybe the issue will gone when we will rebase aspectator to one of the recent versions of gcc.

Important to fix since new distributions come with a new glibc.

The build process is really annoying because of this issue. Maybe we should hurry up and fix it.

Updated by Evgeny Novikov over 5 years ago

This is actually the next step at the CIF road map. But you should wait till August-September.

Ilya updated Aspectator to GCC 7 a long ago. And all such issues have gone.
