[Bug libstdc++/22111] New: [4.0 Regression] libstdc+++ ABI

[themis_hv at yahoo dot co dot uk]

When running the testsuite for GCC 4.0.1 RC 2
(http://gcc.gnu.org/ml/gcc-testresults/2005-06/msg01068.html)

I get the following error:

FAIL: abi_check

The above testsuite failure does not occur with 
GCC 4.0-20050616 snapshot
(http://gcc.gnu.org/ml/gcc-testresults/2005-06/msg01025.html)

What binutils are you using? Can you attach the libstdc++.log after you do "make
check-abi'?

thanks,
benjamin

The log file indicates that symbol versioning is turned off. This is most
probably due to an old version of binutils.

You should see this when configuring libstdc++:

configure: versioning on shared library symbols is gnu

I'm guessing you don't see this message, and instead see a warning that details
what I just described.

We're in the process of updating the docs. See this message for more info:
http://gcc.gnu.org/ml/libstdc++/2005-06/msg00132.html

You can tell the exact version number of ld by issuing:

ld --version

best,
benjamin

Looking through my build log it shows:

configure: WARNING: === Linker version 21500 is too old for
configure: WARNING: === full symbol versioning support in this release 
of GCC.
configure: WARNING: === You would need to upgrade your binutils to 
version
configure: WARNING: === 21590 or later and rebuild GCC.
configure: WARNING: === Symbol versioning will be disabled.

I think it may be a good idea to abort build compared to building it and
generating a testsuite failure.

Why, libstdc++ and the new compiler still works, you just don't get symbol versioning at all.

I know do not get symbol versioning but what is causing the testsuite then?

This isn't a critical error. I think the warning is pretty clear. 

However, it is true that without symbol versioning, 'make check-abi' is pretty
useless. The attached patch corrects this.

Ugh. Well, that's that way it used to work.... apparently now it's different.

Here, this gets to the same place, and removes some misleading bits in the
current  configury.

Please go ahead.

Thanks for doing this in a way that will work with installed-tree testing!
