Hi all, Sorry to bug you again. I'm download the new version 0.20 and I've got compilation error for multipathd. make[1]: Entering directory `/tmp/multipath-tools-0.2.0/multipathd' gcc -pipe -g -O2 -Wall -Wunused -Wstrict-prototypes -DDEBUG=1 -DFLOATING_STACKS -c -o main.o main.c gcc -pipe -g -O2 -Wall -Wunused -Wstrict-prototypes -DDEBUG=1 -DFLOATING_STACKS -c -o devinfo.o devinfo.c gcc -pipe -g -O2 -Wall -Wunused -Wstrict-prototypes -DDEBUG=1 -DFLOATING_STACKS -c -o checkers.o checkers.c gcc -lpthread -ldevmapper -lsysfs main.o devinfo.o checkers.o -o multipathd /usr/bin/ld: cannot find -lsysfs collect2: ld returned 1 exit status make[1]: *** [multipathd] Error 1 make[1]: Leaving directory `/tmp/multipath-tools-0.2.0/multipathd' I found there are some different with 0.1.9 the multipathd does link with -lsysfs but 0.2.0 does. I guess this is a dumb questions... if I compile multipathd to binary without link to -lsysfs the multipathd still be able to run. would it be any different without that?
