Hi, on my machine i have built openssl libraries in static mode only, after
that i want to build ffmpeg library with https protocol support and
configuration failed (undefined reference to 'dlopen') in check_lib openssl
because for linking needed dl library, if linked .so libraries first
check(check_lib
openssl openssl/ssl.h SSL_library_init -lssl -lcrypto) successful.
ldd output is:
ldd /lib/x86_64-linux-gnu/libcrypto.so.1.0.0
linux-vdso.so.1 => (0x00007fff82a6a000)
libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f6795038000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f6794c70000)
/lib64/ld-linux-x86-64.so.2 (0x0000562ba7b11000)
