Problem with 2 different libraries each having it’s own rcc file.
When I link in 2 different libraries ( which each have a QT resource ) I get the following link errors, names have been changed to protect the innocent….
A.lib(Doit.obj) : error LNK2005: “int __cdecl qInitResources(void)” (?qInitResources@@YAHXZ) already defined in B.lib(Foo.obj)
A.lib(Doit.obj) : error LNK2005: “int __cdecl qCleanupResources(void)” (?qCleanupResources@@YAHXZ) already defined in B.lib(Foo.obj)
A.lib(Doit.obj) : error LNK2005: “class qCleanupResources__dest_class__ qCleanupResources__dest_instance__” (?qCleanupResources__dest_instance__@@3VqCleanupResources__dest_class__@@A) already defined in B.lib(Foo.obj)
The resources include only art and are compiled from a QRC file, example below…
<RCC>
<qresource “/myresources”>
<file>images/picture.png</file>
</qresource>
</RCC>
Looking at the rcc file I see that both have the lines
int QT_MANGLE_NAMESPACE(qInitResources)() {…}
int QT_MANGLE_NAMESPACE(qCleanupResources)() {…}
I am building in VS2005 on Windows XP.
Does any one know how I can resolve this?

If you want to link in several resource files compiled with the Qt RCC into the same binary, use the “-name” parameter. And pass a different/unique value to “-name” for each invocation of RCC. This will change the name of the “qInitResources” and “qCleanupResources” functions in the generated code to avoid name conflicts.
