I’m trying to build and run the LegacyLibrary Example of JavaCpp with Visual Studio 2008 on Windows XP Professional (x86) using JDK 1.7.0 and JavaCpp 0.3 (bin), and I get the following output. The error is on the last command, java -cp javacpp.jar LegacyLibrary.

The problem was that Visual Studio 2005 and VS 2008 do not automatically link to internal libraries of VC++. The solution is to either bundle a manifest with the required libraries in the executable, as described here, or to simply use Visual Studio 2010 or newer. I used VS 2010 and I can verify that the example now runs as expected. If you happen to try bundling the manifest, please comment for others to confirm that it’s a valid fix.
