$1 [options] command-line
Split command-line in two parts for linking static applications with
Xenomai user-space posix skin in two stages.
Options:
-q be quiet
-v be verbose (print each command before running it)
-n dry run (print all commands but don't run any)
Example:
$1 -v gcc -o foo foo.o -Wl,@/usr/xenomai/lib/posix.wrappers -L/usr/xenomai/lib -lpthread_rt -lpthread -lrt
will print and run:
+ gcc -o foo.tmp -Wl,-Ur -nostdlib foo.o -Wl,@/usr/xenomai/lib/posix.wrappers -L/usr/xenomai/lib
+ gcc -o foo foo.tmp -L/usr/xenomai/lib -lpthread_rt -lpthread -lrt
+ rm foo.tmp
