Does anyone know what is the problem?
Hi Hong:
Thanks very much for your report which is an extremely important one
in my opinion.
The issue occurs in src/plcore.c when we call lt_dlmakeresident. That
call was put in during the last release cycle by another developer and
me to fix another problem. But we completely missed the fact this
function has not been implemented in ltdl_win32.c, which is the
libltdl replacement that we use just for Windows. Doh!
I think this bug means that 5.9.8 will not work on any Windows
platform. I am not happy that we missed this issue to start with, but
I am even less happy that our Windows testing of this release fell
down so badly, but there it is. We will try to do a lot better for our
further releases!
Could you try the attached patch, please, to see if that solves the
issue? It implements lt_dlmakeresident in ltdl_win32.c, but as a
no-op. Later, we will probably want to actually implement a
lt_dlmakeresident in ltdl_win32.c that does what the libltdl Linux
version does, but this patch is at least a start down that trail, and
should be good enough for now since it should just give the same
Windows platform behaviour as for 5.9.7.
