Hi, the solution is much simpler because there is already a version which does not use GPL_EXPORT functions :
Add: /* this avoids the linking of GPL export symbols from the kernel ! */ #ifndef DM642_PCI # define DM642_PCI #endif to kfile.c (in gpp/src/osal/linux/ ) Ciao, Peter On Mon, 12 Mar 2007, Kevin Hilman wrote: > Yes, DSPlink needs to be fixed for newer kernels where sys_lseek is not > exported to modules. > > > > In the mean time, I have patched my kernel with the attached patch to > export the symbol. > > > > Kevin > > > > > > ________________________________ > > From: Andy Ngo [mailto:[EMAIL PROTECTED] > Sent: Monday, March 12, 2007 3:14 PM > To: Kevin Hilman; Bobby Buck > Cc: davinci-linux-open-source@linux.davincidsp.com > Subject: Re: Problem compiling cmemk with GIT kernel > > > > Kevin, > > I follow your patches and got cmemk.ko to build fine.
