Wrapping executables in a TclApp application
Question:
I've bundled a binary executable inside my TclApp application. My script can see it, but the OS claims it isn't there when I try to run it. How do I fix it?
Answer:
When a TclApp application is created, it creates a virtual filesystem using the Tcl vfs module and puts what it needs in that virtual filesystem. While your application can see inside the VFS, the operating system can't -- hence the error.
The best solution is to extract the executable to a location in the regular filesystem and run it from there. The operating system will be able to see it, and it will work as expected.
