Hi,everyone,
    I checkout FreeBSD‘s source codes to my /usr/src
    I use command
    make buildworld
    int directory /usr/src to build a world.I want to do some debug to lib /usr/src/lib/libthr.If I modified some files in /usr/src/lib/libthr/thread, how could I build libthr except other components of world?
   btw,I execute command
   make
   in /usr/src/lib/libthr get this :

I have no strdup calls anywhere in libthr. If you have added this call,
you need to make sure the right headers are included.

Otherwise, this can be used to build only libthr and works fine on my
system:

cd /usr/src/lib/libthr
make obj && make depend
make

Uli
