# I've again spent days trying to get a working armv6hf compiler going.
|
||||
# God only knows how many recompilations of GCC, GHC, libraries, and
|
||||
# ShellCheck itself, has gone into it.
|
||||
#
|
||||
# I tried Debian's toolchain. I tried my custom one built according to
|
||||
# RPi `gcc -v`. I tried GHC9, glibc, musl, registerised vs not, but
|
||||
# nothing has yielded an armv6hf binary that does not immediately
|
||||
# segfault on qemu-arm-static or the RPi itself.
|
||||
#
|
||||
# I then tried the same but with armv7hf. Same story.
|
||||
#
|
||||
# Emulating the entire userspace with balenalib again? Very strange build
|
||||
# failures where programs would fail to execute with > ~100 arguments.
|
||||
#
|
||||
# Finally, creating our own appears to work when using a custom QEmu
|
||||
# patched to follow execve calls.
|
||||
#
|
||||
# PS: $100 bounty for getting a RPi1 compatible static build going
|
||||
# with cross-compilation, similar to what the aarch64 build does.
|
||||
#
|
||||
# This Docker file uses a custom QEmu fork with patches to follow execve
|
||||
# to build all of ShellCheck emulated.
