Dear JonY and dear users,
i have found another weird clue to my problem.
i just have tried to compile another program of our project that uses the same
library we are talking about.
When linking against the libRELibrary.a, everything is swell. But when linking
against the delay-loaded version, the linker reports errors (See at the end of
this email).
i'm asking myself... Isn't a delay-loaded import library supposed to export the
exact same function the DLL does, but just load the real library when one of
those function is called? If yes, then i may be doing something wrong when
using the gendef / dlltool, it clearly is changing what gets exported in the
delayed.a ...
So maybe i shouldn't do it as an "extra" step, and maybe there is a flag in the
linker to tell it to directly create both the regular and delay-loaded version
of the import lib (And if that flag involves doing something different than
internally calling gendef / dlltool of course)?
The weird thing is that my Qt .pro file (It is like a Makefile generator, if
you don't know about Qt) is targeted to be cross-platform, and the directive i
made works on Mac, the delay-loading is perfectly working.
Also, i tend to agree with what Kai said: I wouldn't assume there is a bug in
the delayload code, it would be very unlikelly coincidence as i'm really new to
this mingw-w64 project, so it *has* to be something i do wrong. How can i know
my mistake for sure?
Thanks guys!
Pierre.
