How to link static libs?

I though it would be somtheing like this:

jextract {
    header("${project.projectDir}/src/main/c/native.h") {
        // The package under which all source files will be generated
        targetPackage = 'org.nativelib'

        // The generated class name
        className = 'NativeLib'

        libraries = ['nativeLib', ':/usr/lib/xharbour/librtl.a', ':/usr/lib/xharbour/libvm.a', ':/usr/lib/xharbour/libcommon.a', ':/usr/lib/xharbour/libmacro.a',
                     ':/usr/lib/xharbour/libpcrepos.a', ':/usr/lib/xharbour/liblang.a', ':/usr/lib/xharbour/librdd.a', ':/usr/lib/xharbour/libct.a',
                     ':/usr/lib/xharbour/libdbfcdx.a',  ':/usr/lib/xharbour/libdbfntx.a', ':/usr/lib/xharbour/libdbffpt.a', ':/usr/lib/xharbour/libhbsix.a',
                     ':/usr/lib/xharbour/libcodepage.a', ':/usr/lib/xharbour/libtip.a', ':/usr/lib/xharbour/libhbcomm.a', ':/usr/lib/xharbour/libdebug.a'

        ]
    }
}

But linking options are:

-shared
-Wl,-soname,libnativeLib.so
-o
/home/pz2/repo/panama-demo-2/build/libs/nativeLib/shared/libnativeLib.so
/home/pz2/repo/panama-demo-2/build/objs/nativeLib/shared/nativeLibC/7iqn0imz8afmagv3khti3yfjc/native.o
/home/pz2/repo/panama-demo-2/build/objs/nativeLib/shared/nativeLibC/9or586zskwg4xeunnqb61mzz5/bccgenerator.o
/home/pz2/repo/panama-demo-2/build/objs/nativeLib/shared/nativeLibC/3s5u5prxpovrs082vjzqxybsk/native.o
-m64

Altho there is succes:

See file:///home/pz2/repo/panama-demo-2/build/tmp/linkNativeLibSharedLibrary/output.txt for all output for linkNativeLibSharedLibrary.
linking libnativeLib.so successful.

Finished linkNativeLibSharedLibrary, see full log file:///home/pz2/repo/panama-demo-2/build/tmp/linkNativeLibSharedLibrary/output.txt.

During execution I get error:
