Make fail due to openssl

cmake works fine, but make failed.

i dont have a macos to help you, unsure if someone here will be able to. your openssl with 1.0.X is supported and there are efforts to support 1.1.X here: #559

for what i see here:

ld: can't link with a main executable file '/usr/bin/openssl' for architecture x86_64

seems like openssl binary is not present in /usr/bin ? maybe creare a symbolic link or copy the binary into that location and make again ?

[oxarbitrage]

also check if some of this can help you:

[LanfordCai]

@oxarbitrage Thank you for your reply:).

I have checked /usr/bin and openssl does present in the directory... And the Building-on-OS-X doc is not work, brew link --force openssl would failed with this warning:

Warning: Refusing to link: openssl
Linking keg-only openssl means you may end up linking against the insecure,
deprecated system OpenSSL while using the headers from Homebrew's openssl.
Instead, pass the full include/library paths to your compiler e.g.:
  -I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib

That's why I added -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl when calling cmake ...

[pmconrad]

-- OPENSSL_LIBRARIES = /usr/local/opt/openssl/lib/libssl.a; /usr/bin/openssl

This looks broken. /usr/bin/openssl is not a library.

I used an ubuntu OS to build the code, and It works well. So I would close this issue. Thank you for your help.
