thanks, this warning is caused by missing prototypes in ktmw32.h header. I added it at revision 6141. > == 2. Link error == > Using x32-4.8.1-release-win32-dwarf-rev4.7z also shows a warning but > fails to link: > > D:\test>gcc test.c -lkernel32 -lktmw32 > test.c: In function 'main': > test.c:4:23: warning: initialization makes pointer from integer > without a cast [enabled by default] > HANDLE transaction = CreateTransaction(NULL, NULL, 0, 0, 0, 0, L"my descr"); > ^ > D:\Data\Temp\1\ccnbgxxV.o:test.c:(.text+0x4e): undefined reference to > `CreateTransaction' > collect2.exe: error: ld returned 1 exit status This happens due missing prototype. For 32-bit this is a stdcall-function, and therefore symbol-decoration is different. Due no prototype, a cdecl-function was searched instead. > The same link error happens with an advapi32.lib function > RegCreateKeyTransactedW(). So it's not only CreateTransaction() or > ktmw32.lib that cause problems in 32-bit. Please make sure you have included winreg.h header. Additional you have to make sure that _WIN32_WINNT is defined >= 0x0600, so that this API is present. This API is just available for Vista and newer OSes. > > Please, fix.
