[Mono-dev] mysql connector Mono 2.6.7 - Cannot find assembly

[Frank Cohen]

Hey V,

Thanks for your reply.  I did as you suggested but I still get the same
error message w/out any more information.  I've actually placed the DLLs in
the same folder as the exe (not mono, Main.exe).  So shouldn't it pick them
up?

Here are a couple more pieces of info: while I was able to get the Windows
command line test working, when I tried to run the web-app in Mono's web
server, I got the same error about the DLL.  On the Cent OS box, I had an
earlier version of Mono installed, then installed from source again.  I
think it's installed correctly as when I run mono --version, it's showing me
2.6.8.

Below is the output from the test program:

** (./Main.exe:17396): WARNING **: The following assembly referenced from
/san/home/www/testproj/Main.exe could not be loaded:
     Assembly:   MySql.Data    (assemblyref_index=1)
     Version:    6.3.5.0
     Public Key: c5687fc88969c44d
The assembly was not found in the Global Assembly Cache, a path listed in
the MONO_PATH environment variable, or in the location of the executing
assembly         (/san/home/www/testproj/).

Thanks,

Frank
