Hi,
I have a problem using external variables in the constructor code of my
shared library. The constructor code is an init() function labeled by gcc
__attribute__((constructor)). In that function I make a reference to an
extern variable X provided by the driving app. The problem is that X is not
yet initialized at the moment init() is invoked, which is before main() is
entered.
A solution might be to introduce a init flag and move the initialization
code to some other exported function, but this is not really elegant. I will
appreciate any alternative suggestion.
