Hi list.
I have managed to build libssh2 in a variety of environments (android
clang, linux gcc, windows mvc, macos clang) and I am completely unable
to build it for iOS 12.2 (didn't try to do it in an older version) with
the specs of the subject (OpenSSL 1.1.1a or 1.1.1b, XCode 10.2.
I doesn't matter what I try. Building it manually, using this iSSH2
script (https://github.com/Frugghi/iSSH2
<https://github.com/Frugghi/iSSH2>), etc. It always fails. From syntax
errors like the following

or mismatch of BITCODE being used in libssh2 and not in openssl
to link error (which is the closest I get to get it built) like this
[100%] Linking C shared library ../../lib/libssh2.dylib
ld: warning: -headerpad_max_install_names is ignored when used with
-bitcode_bundle (Xcode setting ENABLE_BITCODE=YES)
Undefined symbols for architecture armv7:
"_ENGINE_load_builtin_engines", referenced from:
_libssh2_init in global.c.o
__libssh2_init_if_needed in global.c.o
"_ENGINE_register_all_complete", referenced from:
_libssh2_init in global.c.o
__libssh2_init_if_needed in global.c.o
ld: symbol(s) not found for architecture armv7
which normally means that the dependency (openssl) wasn't build for
armv7, but
$ lipo -info libcrypto.a
Architectures in the fat file: libcrypto.a are: armv7 armv7s x86_64 arm64
$ lipo -info libssl.a
Architectures in the fat file: libssl.a are: armv7 armv7s x86_64 arm64
so, not the case either.
I ran out of ideas and I wonder if it is just not possible to do what I
am trying to.
Anybody knows if it is possible and can enlighten me, please?
Thanks in advance.
