Thanks for feedback
You misunderstand and misuse the DEFINE_SYMBOL property. All the
IMPORT_X_DLL symbols are wrong, you have to remove them.
But when building the B, and C dll the import symbols need to be defined
somehow. See my export/import header below.
CMake will only
add the DEFINE_SYMBOL when *building* the specified target, and
otherwise just leave it away.
Not sure I understand.
So, in your code you do something like this:
#ifdef EXPORT_A_DLL
#define A_API __declspec(dllexport)
#else
#define A_API __declspec(dllimport)
#endif
I'll try to see if that works. Right now I do have an exporter/importer header
and it is more complex and looks like (for a target "COMMON"):
#if defined(EXPORT_COMMON_DLL)
#define MTK_COMMON __declspec(dllexport)
#elif defined(IMPORT_COMMON_DLL)
#define MTK_COMMON __declspec(dllimport)
#elif defined(EXPORT_COMMON_PKG)
#define MTK_COMMON __declspec(package)
#elif defined(IMPORT_COMMON_PKG)
#define MTK_COMMON __declspec(package)
#else
#define MTK_COMMON
#endif
Is the problem perhaps that the EXPORT_COMMON_DLL defined symbol is not
"undeffed" so when the B DLL need to Import from A, it can't?

For B and C the definitions are analogous.
