How to link a 64 executable that require an rsrc section and comctl32.dll?

Trying to build UltraDefrag.

Sounds pretty simple, but as soon as you add a rc.o to the link objects of your binary, it will use the 32 bit version of comctl32.dll triggering a 0xc0000007 error on program startup.

This is a known mingw64 bug, but as the bug had no replies since 2011, I need a workaround for this (the program need to not use cygwin.dll, so I can’t use cygwin).

Any ideas ?

Solution

  • This can happen if the application manifest explicitly specifies the 32-bit version of common controls

    i.e. the manifest contains

    <dependentAssembly>
<assemblyIdentity
    type="win32"
    name="Microsoft.Windows.Common-Controls"
    version="6.0.0.0"
    processorArchitecture="x86"
    publicKeyToken="6595b64144ccf1df"
    language="*"
/>

    You need to change the processorArchitecture to:

    processorArchitecture="*"

    If that is the cause of your problem, this is not a MinGW-w64 bug.
