Error during make install

[mattiabaldari]

Hi!

I followed the instruction in the INSTALL file until:

If you want to install libssh after compilation run:
make install

Which gave me the following error:

Building C object src/CMakeFiles/ssh_shared.dir/libcrypto.c.o
/fake/path/libssh-0.7.4/src/libcrypto.c: In function ‘evp’:
/fake/path/libssh-0.7.4/src/libcrypto.c:136:16: error: storage size of ‘md’ isn’t known
EVP_MD_CTX md;

Any idea about this?
PS: I installed all the suggested libraries and packages.
Thank you

looks like you did not run make install in "build" folder but in source folder, let re-try, follow the instruction in /libssh-0.7.4/INSTALL file

Hi SoledaD208,

thank you for your answer, I'm sure I was in the "build" folder, but to be 100% sure I tried again, here's the outcome:

hope this can help, thank you

This isn't a problem with the author's code, it's a compatibility issue with OpenSSL. Hope this helps avoid some unnecessary troubleshooting.

Had the same problem. Just install openssl-1.0 over APT. This resolved the compile issue for me.

Hi PJF16, thank you for your contribute. How did you installed openssl-1.0?
Because I already have OpenSSL 1.1.0g and I am not sure how to downgrade it.

Thank you
