I want both libz.a and libz.so* in /lib.
I wrote a simple test case:
cat Makefile
all:
gcc -c -fPIC -DPIC -o test.o test.c -g
gcc -o libtest.so -shared test.o
gcc -c -o test_main.o test_main.c -g
ar rc libtest.a test.o
mv libtest.a usr/lib
mv libtest.so lib
gcc -o test_main_static test_main.o -L./usr/lib -L./lib -ltest
gcc -o test_main_shared test_main.o -L./lib -L./usr/lib -ltest
If don't install to same directory then it will have problems.
That testcase isn't terribly representative since you have libtest.so
being the actual shared library. In the zlib case, since it has a
proper SONAME, libz.so.1 and libz.so are distinct.
Slightly modified:
cat Makefile
all:
gcc -c -fPIC -DPIC -o test.o test.c -g
gcc -o libtest.so.1.2 -Wl,-soname,libtest.so.1 -shared test.o
gcc -c -o test_main.o test_main.c -g
ar rc libtest.a test.o
ln -s libtest.so.1.2 libtest.so.1
ln -s libtest.so.1.2 libtest.so
mv libtest.a usr/lib
mv libtest.so* lib
gcc -o test_main_static test_main.o -L./usr/lib -L./lib -ltest
gcc -o test_main_shared test_main.o -Llib -L./usr/lib -ltest
