Possible to build a shared library with static link used library?

Question

I can build a executable with gcc with static link:

gcc -static xxx.c -o xxx

So I can run xxx without any external dependent lib

Answer 1

There's some neat hackery you can do with Rpath so that a ELF executable or .so will look for its dependent .so files first in the same directory as itself:

• make a short script echo-rpath consisting of

  echo '-Wl,--rpath=$ORIGIN'

• add that to your build command line as gcc -o file -lwhatever `echo-rpath ` objects

(The echo mechanism prevents Make or the shell from eating the $ sign and ensures it gets passed into ld.)
