Issues compiling x86 variant on Ubuntu 22.04

[nnathan]

Hi,

I'm trying to compile Xinu x86 on Ubuntu 22.04 with the provided gcc toolchain.

I get the following errors:

$ make

The udpAlloc it fixable by adding udp to DEVICES in the platforms/x86/platformVars.

I get the following compile issues this time around:

-e      Compiling ../system/initialize.o
-e      Compiling ../device/udp/udpAlloc.o
../device/udp/udpAlloc.c: In function ‘udpAlloc’:
../device/udp/udpAlloc.c:25:21: error: ‘NUDP’ undeclared (first use in this function)
   25 |     for (i = 0; i < NUDP; i++)
      |                     ^~~~
../device/udp/udpAlloc.c:25:21: note: each undeclared identifier is reported only once for each function it appears in
../device/udp/udpAlloc.c:31:24: error: ‘UDP0’ undeclared (first use in this function)
   31 |             return i + UDP0;
      |                        ^~~~

I can't find to see any symbol/reference to NUDP or UDP0 in the codebase, so I don't know how these get defined.

Furthermore I still have to sort out the linker errors for __stack_chk_fail and I've tried compiling with -fno-stack-protector to disable the stack canaries but the linker errors still persist.

Would appreciate some assistance, thank you.
