You need GTK-2 installed, which is admittedly an older version of GTK. Try installing webkit2gtk

I had the same issue and it seems like the order in which compiler flags are passed to gcc is not right. Try compiling the .so manually via: gcc -shared -o build/webview.so webview.c $(pkg-config --cflags --libs gtk+-3.0 webkit2gtk-4.0) -fPIC -DWEBVIEW_GTK -I$(jpm show-paths | grep header|cut -d' ' -f2)

You can also check your webkit.so whether it was properly linked. If it was NOT properly linked the output of ldd build/webview.so will be very short; ie.:

        linux-vdso.so.1 (0x00007fffbcbde000)
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f75f97f4000)
        /lib64/ld-linux-x86-64.so.2 (0x00007f75f99f2000)

If you use the correct order like above the .so will be linked to a dozen on GTK libs.
