[mico-devel] Cross compiling MICO for eCos

[Karel Gardas]

Hello Patrick,

I think autoconf is not that difficult for cross-compiling. You just need 
to use appropriate target option(s). We've already hacked MICO to support 
cross-compilation to various linux targets (see your MICO sources). I have 
also ported MICO to the RTEMS RTOS without any big issue. So I think the 
problem with eCos port is not autoconf related but rather eCos related. 
While discussing with some commercial customer possibility of MICO/eCos 
port, we have found two possible ways:

1) use eCosCentric eCos libstc++ port as a basis and then do necessary 
changes in MICO.

2) port MICO to the raw free eCos, this means you will also need to 
provide necessary bits of libstdc++ as was done in the past in a form of 
MICO's mini-STL support. This means more work needs to be done.

Independently from the two ways above, you will also need to decide if you 
will be running MICO on top of eCos/POSIX layer or not. If not, you will 
also need top port MICO's threading layer to the eCos thread API.

Anyway, the project I'm talking above has not happened at the end, so if 
your company is interested in funding MICO/eCos port by for example using 
our company support services, please let me know off-list.

Cheers,
Karel
