Title: Compiling with /MD, unresolved externals.
Post by: Trouba on October 30, 2009, 07:16:20 PM

Hi, when compiling using the multi-threaded dynamic version of the runtime library (/MD switch) I ended up with this linker errors:

POLINK: error: Unresolved external symbol '__imp__CreateProcessA@40'.
POLINK: error: Unresolved external symbol '__imp__WaitForSingleObject@8'.
POLINK: error: Unresolved external symbol '__imp__CloseHandle@4'.
POLINK: error: Unresolved external symbol '__imp__GetLastError@0'.
POLINK: error: Unresolved external symbol '__imp__FormatMessageA@28'.
POLINK: error: Unresolved external symbol '__imp__LocalFree@4'.

Any info on how to solve them? Are they not defined in the dynamic version of the CRT?

Thank you.

Those API's are from kernel32.lib

Thank you, strange behavior it has.

If using /MT it links automatically to kernel32.lib, if linking using /MD you have to specify kernel32.lib as a library to link to.
