Hi,
in search of an example on how to cross-compile Lua byte code for a
specific target architecture, I came across this post:
http://lua-users.org/lists/lua-l/2006-06/msg00205.html. We
use Lua 5.3.4 in a project which relies on Yocto in order to build a
customized Linux operating system image for our target hardware – an ARM Cortex A7 32bit processor. On that hardware,
we run some applications that are implemented in Lua. During the build
process, we want to compile our Lua application script files into byte
code for the mentioned target machine. That is, luac shall generate byte code
which can run on the Cortex A7 processor. The whole build
process, especially luac, is automatically executed on a
64bit-Ubuntu-based build server backend in which we cannot integrate the
target hardware for compilation. This is why we need to have a
cross-compilation capable version of luac in our Yocto build system.
In
order to realize that, I would like to patch the Lua sources
accordingly. Unfortunately, I was not able to find any concrete example
which demonstrates on how to change the existing code base for a
specific target architecture. I already had a look at the ldump.c file as
mentioned in the post above. As far as I understand I (only) have to adapt
DumpBlock() since any data produced by the higher-layer functions
finally go through this function. However, I am not sure how to exactly
do that. Is there any concrete example available that demonstrates the
required steps?
Thank you very much in advance.
With kind regards,
Matthias
