Compiler Error C2393

  • Article

'symbol' : per-appdomain symbol cannot be allocated in segment 'segment'

Remarks

The /clr:pure and /clr:safe compiler options are deprecated in Visual Studio 2015 and unsupported in Visual Studio 2017.

The use of appdomain variables implies that you are compiling with /clr:pure or /clr:safe, and a safe or pure image cannot contain data segments.

See /clr (Common Language Runtime Compilation) for more information.

Example

The following sample generates C2393. To fix this issue, do not create a data segment.

// C2393.cpp
// compile with: /clr:pure /c
#pragma data_seg("myseg")
int n = 0;   // C2393
