Crossdev / glib news item
I volunteered to help Diego summarize a news item on "crossdev, glib and
binary compatibility", see http://blog.flameeyes.eu/2011/05/15/
Here's the result; as I am neither a specialist in the topic nor know much
about news items, please be lenient :)
If you are cross-compiling to a 32-bit architecture such as ARM, or if
you are using a 32-bit architecture and have sys-devel/crossdev installed,
please be warned that - unless you follow the advice below - your system
may become seriously broken.
We have recently fixed bug 367351 in sys-devel/crossdev, where the size of
the pthread_mutex_t type was hardwired incorrectly into configure scripts.
Unfortunately, if the size was incorrect before, switching to the correct
value changes the ABI of libgthread. All binaries linked against the previous
glib may thus simply crash.
You will have to ensure the ABI stability before upgrading crossdev.
Information on how to fix this is available at the following URL:
