Please study fpc.cfg file structure , and Lazarus IDE linking options .
On my computer , neither FPC nor Lazarus are installed .


There is an option to specify either dynamic linking or static linking of
libraries .

When static linking is selected , it is necessary to have  static linkable
libraries ( *.a )
of used parts , i.e. , dynamic linkable libraries ( *.so.* ) can not be
used for
static linking .

lazarus static linking of libraries

Comparison of Linux and Windows is not a fruitful action , because they do
not have much similarity
other than being operating systems .
