    can anyone help me out with this problem
    how to solve it as my program is not executing
    David Macek
    @elieux
    It's not even compiling actually.
    It looks like you're missing an entry point. Most often main().

    see its not even executing the simplest one
    i think there is some issue with mingw but don't know how to fix :(
    David Macek
    @elieux
    I don't see anything wrong with the program.
    But you have GCC 6, maybe even a mingw.org toolchain. This is pretty old, so my advice is to use a recent mingw-w64 based toolchain instead.

    I have some issues with my msys2 installation. I can not update the git-for-windows repository. I have tried a lot of different things with the keyring, because it looks like an issue with the key
    Is this a known issue? I could not find any help on google

    Anyone know who owns the gpg key: 91883E11E83DC29D14104DB4EDD44359093056EE - I am having the same sort of problem as @schroeca but for this key instead:

    It's my GPG key. It's the same as @schroeca reported.
    Stephen Lyons
    @SlySven
    But that is a different one, isn't it:
    91883E11E83DC29D14104DB4EDD44359093056EE
    verses:

    @dscho
    The former is a subkey of the latter.
    Have you tried following the steps in the linked wiki page?
    Stephen Lyons
    @SlySven
    Ah, one is your signing key and the other your authentication one?

    AH, RTFM - the wiki step 2 was enough to get things going again...!

    :thinking: Would it be worthwhile publishing that public key to https://keys.openpgp.org ?

    @elieux
    I did look for it there, but somehow missed it.
    Johannes Schindelin
    @dscho
    No, you didn't.
    David Macek
    @elieux
    I guess I expected a printout instead of just a link.

    5 minutes ago it wasn't there :-)
    Was that your Yubikey?
    ;-)

    :D Okay, you got me.

    Yes, it wasn't...

    Ah, it has been a while and the update to my setup needs a 3GB download - and I'm currently on a public WiFI - really need to wait 'til I get home and back on a fat pipe to the Interweb...
