Hi,
According to Understand how to build a MicroEJ Firmware and its dependencies — MicroEJ Documentation there is a tight dependency between a firmware and the microejruntime.a
.
How can I be sure I am using the correct microejruntime.a
? Is there a built-in mechanism? Will it always fail at link-time? Will the application crash with weird errors?
Best,
Hi,
Yes, microejapp.o
is tightly coupled with microejruntime.a
: it must be generated from the Platform where microejruntime.a
has been extracted.
In case you try to link a microejapp.o
with microejruntime.a
from an other Architecture version, SNI_startVM
function will return the error code -1
. This error code is defined in LLMJVM.h
. See also error codes documentation for more details.
You may also get unexpected link errors if the internal dependencies between the two files have changed.
