Re: build and Compile ceph in development mode takes an hour

HI Brad,

After exploring Ceph, I found sometimes when I run make command without

removing the build folder, it will end with this error:

/home/agung/project/samc/ceph/build/bin/init-ceph: ceph conf ./ceph.conf not found; system is not configured.

rm -f core*

ip 127.0.0.1

port 6789

NOTE: hostname resolves to loopback; remote hosts will not be able to

  connect.  either adjust /etc/hosts, or edit this script to use your

  machine's real IP.

I have tried to remove the ceph.conf and clean up the temp/ folder before run OSD=3 MON=3 MDS=1 ../src/vstart.sh -n -x -l.

But still did not work. probably you have any suggestion?

Sure, just use the same build directory and run "make" again after you make code
changes and it should only re-compile the binaries that are effected
by your code
changes.

You can use "make -jX" if you aren't already where 'X' is usually
number of CPUs / 2
which may speed up the build.

HTH,
Brad
