When building Qtwebkit (with Perl and MinGW paths in the PATH envirment var, and through the Qt command prompt), I exit with the following errors, which I can not really make out what they are. cd WebCore\ && mingw32-make -f Makefile mingw32-make[1]: Entering directory `C:/QtWebkit/WebKitBuild/Release/WebCore' mingw32-make -f Makefile.Release mingw32-make[2]: Entering directory `C:/QtWebkit/WebKitBuild/Release/WebCore' g++ -enable-stdcall-fixup -Wl,-enable-auto-import -Wl,-enable-runtime-pseudo-rel oc -Wl,-s -mthreads -Wl -shared -Wl,--out-implib,c:\QtWebkit\WebKitBuild\Release \lib\libQtWebKit.a -o "..\lib\QtWebKit.dll" object_script.QtWebKit.Release -L"c :\Qt\4.3.1\lib" -lQtXml4 -lQtGui4 -lQtNetwork4 -lQtCore4 Creating library file: c:\QtWebkit\WebKitBuild\Release\lib\libQtWebKit.a ./tmp\HTMLFormElement.o:HTMLFormElement.cpp:(.text+0x41d7): undefined reference to `_imp__PathFindFileNameW@4' collect2: ld returned 1 exit status mingw32-make[2]: *** [..\lib\QtWebKit.dll] Error 1 mingw32-make[2]: Leaving directory `C:/QtWebkit/WebKitBuild/Release/WebCore' mingw32-make[1]: *** [release] Error 2 mingw32-make[1]: Leaving directory `C:/QtWebkit/WebKitBuild/Release/WebCore' mingw32-make: *** [sub-WebCore-make_default-ordered] Error 2 Your vendor has not defined POSIX macro WEXITSTATUS, used at WebKitTools\Scripts \build-webkit line 141 C:\QtWebkit> Anyone got any advice what this is and what to do?
