Unknown type found [long]

[obiwanjacobi]

Noob here.

I get this error:
CppStruct [PFactoryInfo]/long flags error : Unknown type found [long]

and have tried several things to fix it but to no avail... I suspect the FactoryFlags are the problem (see source code below).
(I have trouble deciphering the docs on where these xml tags go precisely. Sometimes it is mentioned but not always. No errors when you do it wrong too.)

Can anybody shed some light on this?

The mapping file:

        <assembly>SharpGenToolsTest</assembly>
	<namespace>SharpGenToolsTest.Interfaces</namespace>
	<depends>SharpGen.Runtime</depends>

        <sdk name="StdLib" />
	<sdk name="WindowsSdk" />

        <include-dir .... />

        <include file="ipluginbase.h" namespace="SharpGenToolsTest.Interfaces">
		<attach>IPluginBase</attach>
		<attach>PFactoryInfo</attach>
		<attach>PClassInfo</attach>
		<attach>IPluginFactory</attach>
		<attach>PClassInfo2</attach>
		<attach>IPluginFactory2</attach>
		<attach>PClassInfoW</attach>
		<attach>IPluginFactory3</attach>
	</include>

Source code:

struct PFactoryInfo
{
	enum FactoryFlags
	{
		kNoFlags = 0,
		kClassesDiscardable = 1 << 0,	
		kLicenseCheck = 1 << 1,	
		kComponentNonDiscardable = 1 << 3,	
		kUnicode = 1 << 4
	};

	enum
	{
		kURLSize = 256,
		kEmailSize = 128,
		kNameSize = 64
	};

	char8 vendor[kNameSize];
	char8 url[kURLSize];
	char8 email[kEmailSize];
	int32 flags;
};

Looks like some missing bindings?

Adding this to the mapping file fixes it:

<bindings>
	<bind from="long" to="System.Int32" />
	<bind from="unsigned long" to="System.UInt32" />
</bindings>

(Onto new errors...)

[jkoritzinsky]

Long in C maps to either Int32 or IntPtr depending if the sourcs are compiled on Windows or non-Windows. I believe we have a NativeLong and NativeULong type in 2.0 that we map to instead to ensure correct behavior on all platforms.

@jkoritzinsky yeah, long should've resolved to SharpGen.Runtime.NativeLong. It looks like it didn't, as if SharpGen.Runtime is not referenced.

I am getting the same issue, I used NuGet and added both SharpGen.SDK and SharpGen.Runtime.

If I add

<bindings>
    <bind from="long" to="System.Int32" />
    <bind from="HWND__" to="System.IntPtr" />
  </bindings>

It works and generates the code. But without it it fails.
