I like playing HL2 very much and have some ideas for a mod and some maps. So I downloaded the source SDK including Hammer4. But there seems to be a problem with the file vstdlib.dll. I cannot start any of the SDK tools. Always an entry point not found in vstdlib.dll (for example "Q_StrRight"). Maybe it's the wrong versioin of the File? There is an entry point called q_strrchr in vstdlib.dll but for example hammer.dll refers to Q_StrRight in vstdlib.dll.
I even tried to compile a new vstdlib.dll out of the files vstdlib.h and the file located in the folder "vstdlib" (strtools.h, etc..) but this also didn't work.
If someone has a working vstdlib.dll, please send it to me: noackstefan@gmx.de
