Command-line compiler can't find assembly in GAC

[Frank Rizzo]

I have a batch script that is supposed to compile this script:

vbc.exe /main:Form1 /target:winexe
/imports:Microsoft.VisualBasic,System,System.Collections,System.Data,System.Diagnostics,System.Drawing,System.IO,System.Net,System.Text,System.Windows.Forms
/r:System.dll,System.Data.dll,System.Drawing.dll,System.Windows.Forms.dll,Sybase.Data.AseClient.dll
/out:Advanced.exe Form1.vb

When I ran this command, I get an error:

vbc : Command line error BC2017 : could not find library
'Sybase.Data.AseClient.dll'

I know that this library in the GAC, because I can see it in
c:\windows\assembly and the physical folder location of the
Sybase.Data.AseClient.dll is in the Path environment variable.

What am I missing here?

Thanks.

Frank,

What am I missing here?

The compiler doesn't look in the GAC, and it probably doesn't look in
all PATH directories either. It does look in the framework directory
and any directories you specify with /lib.

vbc.exe (and csc.exe) do not search the GAC for compile-time references.

vbc searches:

1) the current working directory
2) the CLR system directory (ie.,
c:\WINDOWS\Microsoft.NET\Framework\v1.1.4322, not the GAC)
3) directories specified by /libpath option
4) directories specified by the LIB env. variable

csc.exe has a similar search strategy, except that /lib is used instead
of /libpath.

You'll need to have a copy of the Sybase.Data.AseClient.dll in one of
the above locations (or specify the full file-system directory name for
the GAC located instance)

Thanks. Step 4 worked for me. BTW, where did you get this info?

It was in the compiler's online docs for the /libpath (or /lib) command
line compiler options.
