No

Expected result: MinGW able to build program with SetProcessDEPPolicy call; actual result: MinGW with latest w32api can compile but not link such a program.

MinGW does not appear to export the Win32 SetProcessDEPPolicy (see http://msdn.microsoft.com/en-us/library/bb736299%28VS.85%29.aspx ) call in its link libraries. w32api 3.13 added it to the headers (see http://old.nabble.com/New-Release:-w32api-3.13-td20866320.html ), but whilst compiling works fine, linking fails (see attached file for this program):

C:\Users\User>gcc -Wall -pedantic -ansi -c spdp_test.c

C:\Users\User>gcc -Wall -pedantic -ansi spdp_test.c
C:\Users\User\AppData\Local\Temp\cc6KmPer.o:spdp_test.c:(.text+0x1e): undefined reference to `SetPro
cessDEPPolicy@4'
collect2: ld returned 1 exit status

According to the MSDN page linked, this function lives in kernel32.dll; well, running nm on MinGW\lib\libkernel32.a finds no DEP functions exported.

    Test program which does nothing but call SetProcessDEPPolicy

  • I've regenerated kernel32.def to capture the missing function export. Thank you for the test case to validate the fix. This will be included in the next w32api release.
