Visual C++, Precompiled Headers and Windows 7
Posted by Brian Seekford in Bugs, Rants on December 5, 2009
I upgraded to Windows 7 and I really am enjoying the new interface….but….. I went to compile my ActiveX toolset projects that are all written in C++ and I started getting precompiled header errors.
So I rebuilt and rebuilt and still got the error:
Error 1 fatal error C1859: ‘.\Release/HTTP Wizard.pch’ unexpected precompiled header error, simply rerunning the compiler might fix this problem d:\SSI\C++\v3\HTTP Wizard v3\HTTPAccess.cpp 5 HTTP Wizard
So I rebuilt and rebuilt. No avail. I turned off Precompiled headers and then everything worked fine. What a pain.
It turned out the reason is due to the virtual tables being rebased by Windows 7 for security which totally screws up the precompiled header logic, which requires the headers to be in the same memory locations.
Apparently the development team at Microsoft knows about the issue and will eventually fix it. So, lets hope that service pack comes out soon.
I guess I am lucky my build machine is really beefy, but for active development having the precompiled header is nice.
So, go have a Margarita and the compiler errors won’t bother you as much…..
ASP.NET State server won’t start on Windows 7 64 bit. File is missing?
Posted by Brian Seekford in .NET Development, Bugs, IT Knowledge on November 23, 2009
I went to launch my state server for ASP.NET to handle my local sites state information, in preparation for production, and the service just wouldn’t play nice. I tried to start it and it says the file doesn’t even exist.
Good times, right? So I went into the registry to see where it was pointing..%SystemRoot%\Microsoft.NET\Framework\v2.0.50727\aspnet_state.exe (Yes, the path is visible on the service control properties as well)
I checked the disk and surprise surprise, it actually wasn’t there. However, there is this suspiciously obvious looking folder called Framework64. AHAH! You look in there and voila! It is in there.
Looks like the framework installer sucks. So I fixed the key and it magically started working. Amazing how when you point to the actual file it works,eh?
The fix is to change this:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\aspnet_state
key: ImagePath
%SystemRoot%\Microsoft.NET\Framework\v2.0.50727\aspnet_state.exe
to this:
%SystemRoot%\Microsoft.NET\Framework64\v2.0.50727\aspnet_state.exe
Happy coding!
