RE: support with openssl 1.1.0x

From: Kees Dekker <Kees.Dekker_at_infor.com>

I first have built OpenSSL (1.1.0.c, which built fine), then tried to build libssh2. Libssh2 (1.8.0) is configured with:

CDPATH= cd /vobs/obj.RHAT7/thirdparty/libssh2/64bit/libssh2-1.8.0; CC=gcc CFLAGS=" -m64 -march=corei7 -mmmx -msse -msse2 -msse3 -msse4 -mfpmath=sse " MAKEFLAGS= MFLAGS= ./configure --prefix=/vobs/obj.RHAT7/thirdparty/libssh2/64bit/libssh2-1.8.0/build --without-libz --with-openssl --with-libssl-prefix=/vobs/obj.RHAT7/thirdparty/OpenSSL/64bit/openssl-1.1.0c/build

While the required (but renamed as of openssl 1.1.0x) include files (only some are shown below) and libraries exist (in lib, not lib64):

See part of config.log:

I was expecting here a -I flag to tell the compiler the path to the include files. When I add a set -x on line configure:16463., then I get the following output:

Note the 'lib64' part in /vobs/obj.RHAT7/thirdparty/OpenSSL/64bit/openssl-1.1.0c/build/lib64/libssl.a. This is unexpected for me, and probably incorrect in the configure script (additional_libdir="$withval/$acl_libdirstem" from configure:16521. I don't know why the configure script likes to take 'lib64', while there is no necessary relationship by a user provided prefix dir for OpenSSL and a system lib64 prefix (acl_libdirstem is set at line 14237, and is related to something else than OpenSSL, isn't it)?

Why is $acl_libdirstem used for OpenSSL (and also for some others, e.g. libbcrypt_prefix)?

Even replacing additional_libdir="$withval/$acl_libdirstem" by additional_libdir="$withval/lib" did not fully help. Now the libs are correctly set, but the include (-I flag) is still omitted, see configure output:

Config.log shows (i.e. correct library path now, but missing -I /vobs/obj.RHAT7/thirdparty/OpenSSL/64bit/openssl-1.1.0c/build/include flag):

      configure:16946: checking for libssl
      configure:16965: gcc -o conftest -m64 -march=corei7 -mmmx -msse -msse2 -msse3 -msse4 -mfpmath=sse conftest.c /vobs/obj.RHAT7/thirdparty/OpenSSL/64bit/openssl-1.1.0c/build/lib/libssl.a /vobs/obj.RHAT7/thirdparty/OpenSSL/64bit/openssl-1.1.0c/build/lib/libcrypto.a >&5
      conftest.c:24:25: fatal error: openssl/ssl.h: No such file or directory

      configure:16965: $? = 1

There are at least two issues: wrong LIB path and missng include path.
The missing include path is probably related to the reset of additional_includedir= directive in configure:16737 (and also using $acl_libdirstem). I'm not sure.
For me libssh2 is not very important on Linux/UNIX (I only use it for now on Windows). If I have time, I will perform more checking to figure out why the include path is not correctly added to the compiler flags.
Maybe you are already able to draw a conclusion on previous output.

I do nothing but 64 bit builds.

I think the configure log might help *you* figure out why the script fails to
detect openssl.

Did something change in terms of placement of libraries when openssl was
bumped to 1.1.0 ? I've build libssh2 with openssl 64 bit since basically
forever.
