I have a large project in C++ Builder that seems to have used the function Import Type Library. In it is a file with a header like this

// ************************************************************************ //

As you can see this file was genereated quite long time ago :). I have been able to build this project using C++ Builder 2010 on Windows 7 64-bit. But when I install XE2 and try to fix all the small issues that arise since it now defaults to STRICT instead of NO_STRICT, I run into a totaly different issue. The above file, ad others generated in the same way, they no longer work as intended.

I get errors like

[BCC32 Error] MSMQ_OCX.h(66): E2090 Qualifier ‘Oleserver’ is not a
class or namespace name

Looking for the MQOA.DLL it claims to have used nothing of the sort seems to exist. Does anyone have any pointers on how to get around these kind of problems when updating the project to XE2? The project has survived upgrades before and was lastley upgraded to C++ Builder 2010. But I’m more of a Visual Studio person so a lot of the Embarcadero stuff is new territory.

    I ended up re-importing the type libraries needed and deleting the old ones, as suggested by Remy Lebeau. It was Microsoft’s libraries for Message Queues and XML in my case.

    Note that some other issues giving similar error messages CAN be that the compiler is just confused :). Try compiling without NO_STRICT defined.
