Hi All, We are developing a block device driver on linux-2.6.x kernel. We want to distribute our driver as sum of source code and librabry/object code. We have divided the source code into two parts. The os interface module and the device interface module. The os interface module (osint.c) has all the os interface functions (init, exit, open, close, ioctl, request queue handling etc). The device interface module (devint.c) on the other hand has all the device interface functions (initialize device, read, write etc), these don't use system calls or kernel APIs. The device interface module is proprietary source and we don't intend to distribute it with source code on GPL license. What we intend to do is, distribute the os interface module (osint.c) with source code and the device interface module as object code or library. The user will compile the os interface module on the target box and link it with the device interface module to generate the .ko (loadable module). We are not very sure of how to achieve this. Please help us address this issue. Thanks in advance, -Jinu -- Kernelnewbies: Help each other learn about the Linux kernel.
