wsock32.dll missing error - solution

Mike A's picture


I ran into problems when trying to run my 32bit application on Windows xp64 / Windows 7 x64. Windows would complain that it could not load my step dll that relied on tkstep.dll.

After checking with dependencywalker it could not find wsock32.dll even though it was on the system.

After various searches, etc. wsock32.lib/dll is not needed as the functionality is within ws2_32.lib/dll. After rebuilding TKSTEP without linking in wsock32.lib everything works as expected.

Hopefully this will be found for the next release of OpenCascade, but incase anyone else finds this problem, just remove wsock32.lib from the list of linked in libraries.
