--- Comment #41 from Andrew Eikum aeikum@codeweavers.com --- (In reply to Rafał Mużyło from comment #40)
I'd probably go with a warning instead of an error, since many distros don't ship 32-bit gstreamer and I don't want to kill those builds because they happen to have 64-bit gstreamer installed.
This is the part we keep misunderstanding each other - I don't see how you could construct such case.
I'd put AC_MSG_ERROR only in case gstreamer is detected, but is mismatched.
If it's not detected, we're not in the branch.
You're right. I was thinking the headers were sufficient to get into the branch, but the error will only occur if 32-bit gstreamer SO files are present. Do you want to write a patch, or shall I add this to my TODO list?
