OpenSSL 1.1.1

[filom]

I have issues compiling libssh for arm64, while armv7 is ok.

global.c:48:9: error: implicit declaration of function 'ENGINE_load_builtin_engines' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
        libssh2_crypto_init();
        ^
../src/openssl.h:231:3: note: expanded from macro 'libssh2_crypto_init'

configuration:
Libssh2 version: 1.8.0 (Automatically detected)
OpenSSL version: 1.1.1 (Automatically detected)
SDK version: 11.4 (Automatically detected)

All right with OpenSSL 1.1.0i.
Any ideas ?

I have the same problem (Libssh2 1.8.0, OpenSSL 1.1.1, iOS SDK 12.0), but it works with the previous version of OpenSSL ./iSSH2.sh -o1.1.0i

[jpalten]

same here...

I'm not sure how to fix it, it seems that Libssh2 1.8.0 is not compatible with OpenSSL 1.1.1 or I'm not finding any flags/settings to make it working.

If you don't need OpenSSL 1.1.1, I'd follow @noefroidevaux suggestion to compile with OpenSSL 1.1.0i.

It might be worth making a note of this in the readme or automatically choosing v1.1.0i

You can use OpenSSL 1.1.1 with libssh2 master branch. You can download it from snapshots: https://www.libssh2.org/snapshots
Just modify iSSH2-libssh2.sh so that it takes the url from snapshot and use one snapshot version:
./iSSH2.sh -l 1.8.1-20190227

./iSSH2.sh -o1.1.0i -l1.8.0 works for me

See Jan-E@6b2b61d for a fix. Read the comment below the commit as well.

FWIW: with the commit at Jan-E@6b2b61d updating to libssh2 1.8.2 with OpenSSL 1.1.1b was a breeze. Note the 'patching file src/openssl.h' after downloading libssh2:

TFRs-Mac:iSSH2 tfr$ ./iSSH2.sh --openssl=1.1.1b --libssh2=1.8.2
