I'm confused. Why don't you just use the linker to put in the data that
you want? The most portable way to do this is just stuff everything
into a const char and compile it. If you want to skip the
octets->.c->.o overhead I suppose you could use objcopy to go directly
from octets->.o, or use a linker script for more control.
If the goal is to avoid having the whole development environment
including headers on the machine performing the append, then ship a
partially linked version of the lua executable with a weak symbol that
will be supplied by the .o containing the octets. The target machine
then just needs objcopy and a linker.
If you can't depend on having a linker on the target machine, yeah,
you're going to have to play around with libelf like lhf says. But just
about everybody has a linker.
Not on Windows.
A typical use I saw with AutoIt, an tool to automate GUI tasks on
Windows, is to have an exe (the runtime) and a tool to glue the user's
code to the exe to make self-running scripts.
The target is end users, knowing (near to) nothing to programming (the
syntax is very primitive, close to .bat/.cmd), which are unlikely to
have any programming tool like a linker.
