Compiling on Raspberry Pi

[daddyfix]

Hey. I trying to compile your C program on Raspberry Pi but I keep getting header conflicting errors... ie. types.h:15:26: error: conflicting types for ‘fd_set’

1. Installed the Raspberrypi headers
2. modified the gcccommand in Makefile to -I (include the header path)
3. modified the includes to point to the correct subdir path

But I still get these errors... can you please help?

make
gcc -I /usr/src/linux-headers-5.10.63-v8+/include -O2 -g -Wall   -c -o psmsd.o psmsd.c

Yeah, that code was never ported to Linux - it was written for Solaris systems a long time ago. I've made a quick go at fixing parts of the code so that it atleast compiles on an Ubuntu 20 Linux system now. Not really tested though...

Wow. Thats great. Im going to give it a try! Thanks

Thanks Peter. Compiled and runs on Raspberry Pi Model 4 B.
