[seL4] CAmkES Templates

Hello, I am working on a CAmkES application attempting to build a seL4 Network Stack. I am basing this on the CAmkES-VM and utilizing UDP Protocol with the lwIP library. During my build process, I get quite a few linking errors like this: undefined reference to `pbuf_alloc' This is odd, because in the templates, the proper header files are being linked in. There are also warnings like this: Warning: no template for ethdriver_1.to.source Even though the connection does exist: connection seL4Ethdriver eth_driver(from router.ethdriver, to ethdriver.client); Is there something obvious I am doing wrong? Thanks Chris
