Why not just use the pkg-config with the proper --static flag?

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)

Hi, i also wait you replay in attach you can find config.log, this
reproduced only on raspbian os, i used clean system. On Armbian, Debian
builded with ssl support without issues.

(This really belongs to ffmpeg-user.)

If the static libcrypto.a requires "-dl", its pkg-config file should
say so, i.e.
$ pkg-config --static --libs openssl
should include "-dl". If not, I believe it's wrong (for your particular
library).

Hi, thank you for replay but output of pkg-config --static --libs openssl
is next:

-L/usr/local/lib -lssl -ldl -lcrypto -ldl

Also i built openssl without any flags, simple execute: ./config && make &&
make install
