Re: [Linux-decnet-user] DAPFS 2.4.1+ Make error on Linux Kernel 2.4.18-3

Hi,

I've not looked at dapfs for quite a while now. You will be safe to change the
malloc.h for slab.h as the comment suggests, thats the easy part. As for the
rest of the code, it may need some work to get it going properly.

The other problem you are seeing is probably due to missing prototypes in
a header file or something similar,

Steve.

I am a complete novice at kernel rebuilds, and as a result have not been able to find the cause of (what I think is ) the linking problem.

> There was however, a problem in applying the dapfs patch to the 2.4.18-3 kernel source, but I believe it was because of a change related to the inclusion of jfss2 in the vfs somewhere between 2.4.1 and 2.4.18.   The patch problem (also below) was inserted manually and seems to be ok.    I have decnet connectivity to the target VMS 5.42 system after successfully compiling the source for dnprogs 2.20.   The commands dncopy, dndir and dntype have all been successful but of course dnmount fails.
