hi, i found about aboriginal through busybox, https://busybox.net/FAQ.html#build
Hello.
i've got an ARM-based system running busybox. and i'm trying to learn how to compile simple programs for it. the examples i use were from busybox-tiny utilities (i.e. Dropbear SMTP, ntpclient).
i downloaded prebuilt compiler for arm to my linux machine (http://landley.net/aboriginal/downloads/binaries/cross-compiler-armv6l.tar.gz) and unzipped into a working directory.
Use armv5l, it's backwards compatibleand the system image works. The armv6l target won't boot under qemu due to kernel version skew. (The kernel needed a patch I stopped forward porting.)
what i'm not sure is how to cross compile the program on my linux machine. i navigated to directory containing 'ntpclient' and run the following:
CROSS_COMPILE="$PWD/cross-compiler-armv5l/bin/armv6l-"
v5 vs v6 doesn't match?
CROSS_COMPILE="$CROSS_COMPILE" make
You could should need to set it to itself, you can just do:
CROSS_COMPILE="$PWD/cross-compiler-armv6l/bin/armv6l-" make
but the resulted 'ntpclient' executable seems still is for linux instead of 'arm' (it won't run on my embedded system).
I dunno what ntpclient package you're trying to build. In theory if it's listening to CROSS_COMPILE the build should die if you point it at a nonexistent file. So possibly that package doesn't know about the CROSS_COMPILE variable?
need some pointers on how to use aborginal Prebuilt Binaries.
These days I'm migrating to http://github.com/richfelker/musl-cross-make toolchains, but haven't had time to work on this recently. ($DAYJOB is in frantic deadline mode, I'm a week into a 2-week stay in san francisco, then I head to san diego for 2 weeks, then I get back to austin long enough to start a road trip to visit family for christmas...)
