Title: POCC5/AMD64: __WSAFDIsSet unresolved + Internal error: reduce_tree()
Post by: vszakats on August 26, 2008, 09:59:35 PM

Hi Pelle,

I've found two possible bugs in version 5 when using AMD64 mode.
Both examples work fine if compiled/linked with version 5 in x86 mode though.

version (everything downloaded from homepage about 2 months ago)

1) Yes, a bug. Can be fixed from the command line:

a) run polib:
> polib -machine:amd64 -makedef:temp ws2_32.lib
(this will create a text file called temp)

b) edit temp, add a second underscore at the beginning of WSAFDIsSet (_WSAFDIsSet --> __WSAFDIsSet), save modified temp.

c) run polib again:
> polib -machine:amd64 -def:temp -out:new_ws2_32.lib
(this will create new_ws2_32.lib which should replace ws2_32.lib -- but make a copy of ws2_32.lib for safety!)

2) I can reproduce it. Maybe I can fix it too.

__WSAFDIsSet still missing from 64-bit ws2_32.lib.
