Recently, when I want to migrate some QNX4.25 programs to QNX6.20,I met
the follow problems:
1,after I run ‘mig4nto’ under QNX4.25 command line,I used ‘cmp’ utility to
compare the marked file and the old file(the old file contained
qnx_name_locate() function),but result display the two files exactly the
same. Now my question is where is the ‘mark’ information(documents said
‘mig4nto’ will add some aditional information to the QNX4.25 codes).
2,‘mig4nto-procmgr’ must run at QNX6.20 to solve some QNX4.25 specific
functions,so I think this solution will take additional system
overheads,especially in some critical realtime control system, something
like our project. In this way, we want to rewrite all of our codes(about
4000 lines) under QNX6.20,is our thought right?
any segguestion will be greatly appreciate.
