Ok so I am going to take a break for the night but here are my steps that I have taken based on a lot of what I have seen in the archives here to give everyone a better idea of what exactly im doing. Maybe Im missing something, which Im sure...

My setup is Ubuntu 22.04.1 on a VM.

Now all of my steps to this point... Well more but who's counting....

Created folder called ~/workspace

Extracted my targets SDK contents into ~/workspace

Entered the 2 environment veriables

PATH=$PATH:~/workspace/staging_dir/toolchain-mipsel_24kc_gcc-11.2.0_musl/bin

export PATH

STAGING_DIR=~/workspace/staging_dir/toolchain-mipsel_24kc_gcc-11.2.0_musl/bin

export STAGING_DIR

Downloaded and extracted ampr-ripd-2.4.1 source files here: ~/workspace/dl/ampr-ripd-2.4.1

Entered into ~/workspace/dl/ampr-ripd-2.4.1 and....

Entered make CC=mipsel-openwrt-linux-musl-cpp LD=mipsel-openwrt-linux-musl-ld

(Used cpp because I saw someone in the archives from way back who used it)

and got:

mipsel-openwrt-linux-musl-cpp -Wall -O2 -D HAVE_DEBUG -o ampr-ripd ampr-ripd.c

ampr-ripd.c:125:10: fatal error: bits/getopt_core.h: No such file or directory

125 | #include <bits/getopt_core.h>

| ^~~~~~~~~~~~~~~~~~~~

compilation terminated.

make: *** [Makefile:30: ampr-ripd] Error 1

For S & G's I tried it with the other compilers, c++, g++, gcc and got the same response.

Commented out:

//#include <bits/getopt_core.h> in ampr-ripd.c

Retyped: make CC=mipsel-openwrt-linux-musl-cpp LD=mipsel-openwrt-linux-musl-ld

and got:

mipsel-openwrt-linux-musl-cpp -Wall -O2 -D HAVE_DEBUG -o ampr-ripd ampr-ripd.c

ampr-ripd executable (assuming) appears in the folder. I think I'm doing good at this point.

Moved the executable to /usr/sbin on the target (Netgear R6220) and ran ./ampr-ripd

and got:

root@OpenWrt:/usr/sbin# ./ampr-ripd

(I saw this error in the archives but had no answer for his issue)

Deleted the assumed executable from the working environment and....

Changed compilers

make CC=mipsel-openwrt-linux-musl-gcc LD=mipsel-openwrt-linux-musl-ld

and got:

mipsel-openwrt-linux-musl-gcc -Wall -O2 -D HAVE_DEBUG -o ampr-ripd ampr-ripd.c

ampr-ripd.c: In function 'create_fwsd':

2239 | (udh->source == htons(IPPORT_ROUTESERVER)))

make: *** [Makefile:30: ampr-ripd] Error 1

(I got the same when using some of the other compiler options)

so I added to ampr-ripd.c as seen in the groups

#define IPPORT_ROUTESERVER 520

Retyped: make CC=mipsel-openwrt-linux-musl-gcc LD=mipsel-openwrt-linux-musl-ld

now i get:

mipsel-openwrt-linux-musl-gcc -Wall -O2 -D HAVE_DEBUG -o ampr-ripd ampr-ripd.c

ampr-ripd.c: In function 'main':

ampr-ripd.c:2240:49: error: 'struct udphdr' has no member named 'dest'

2241 | (udh->source == htons(IPPORT_ROUTESERVER)))

| ^~

make: *** [Makefile:30: ampr-ripd] Error 1

Stopped right here and this is where Im staying for now. LOL

Whats next gang?

Thanks a million if i had it give away....
