I have Class xxx.cpp which can be converted to a static library instead of creating a shared object to improve the performance of the system. Hence please provide the steps to convert it from .so to .a.

    If you have the source, can't you just compile it as a static library? – Cornstalks May 08 '16 at 05:07
  • There is no "converter" from *shared* to *static* libraries. They are different ways of *compiling* a library. A *static* library is created with e.g. `ar -cvq foobar.a foo.o bar.o`. A shared library is created via `gcc -shared ...`. The steps to covert is simply to recompile as a static lib. – David C. Rankin May 08 '16 at 06:40

No conversion is required here since you have the source file xxx.cpp

You may

  1. Create the library first 

    g++ -static -c xxx.cpp -o xxx.o # use g++ instead of gcc
ar -rcs libxxx.a xxx.o

  2. Link to the library like below 

    g++ -static somefile.cpp -o somefile.elf -L/path/to/libxxx.a -lxxx
