Build objects twice for shared and static libraries
|
||
|
|
|
||
|
|
The existing Makefile causes problems on MIPS because the same object
|
||
|
|
files (not compiled with -fPIC) are used in static and shared libraries.
|
||
|
|
MIPS will refuce to link non-pic objects in shared libraries.
|
||
|
|
We fix this problems by creating a new rule for the shared library
|
||
|
|
and build the shared objects as *.sho instead of *.o.
|
||
|
|
Then, we use these objects to create the shared library.
