[cfe-dev] Problem loading plugin dll into clang under Windows

[Marcel Schaible via cfe-dev]

Hi,

I have developed a plugin for clang (latest version from svn). The 
plugin (x64) loads and executes just fine with the clang I have build 
from my svn tree. But when I try to load the plugin into the official 
binary clang distribution (LLVM-4.0.1-win64) I'll get the error below.

I suspect that I have to link the dll with some special options. Is 
there somewhere a description of the build environment for Visual Studio?

Btw: I am building the stuff with Visual Studio 2017 Enterprise.


"c:\Program Files\LLVM\bin\clang"  -fplugin=MyPlugin.dll  -c 
d:\clang+llvm\tests\simple.c -o d:\clang+llvm\tests\simple.o

error: unable to load plugin 'MyPlugin.dll': 'MyPlugin.dll: Can't open: 
Unknown error (0xC1)'

Thanks for your help

Marcel
