OpenSSL CMake problem (Ubuntu server)

[toni]

I would appreciate some help with this CMake Errors. The information is from a machine that runs Ubuntu server.
Core: TrinityCore 4.3.4

--> UPDATE 01 <--

I have opened FindOpenSSL.cmake and checked lines 188,200-203

file(STRINGS "${OPENSSL_INCLUDE_DIR}/openssl/opensslv.h" openssl_version_str
REGEX "^#define[\t ]+OPENSSL_VERSION_NUMBER[\t ]+0x[0-9][0-9][0-9][0-9][0-9][0-9].*")

string(REGEX REPLACE "^.*OPENSSL_VERSION_NUMBER[\t ]+0x([0-9a-f])([0-9a-f][0-9a-f])([0-9a-f][0-9a-f])([0-9a-f][0-9a-f])([0-9a-f]).*$"

list(GET OPENSSL_VERSION_LIST 2 OPENSSL_VERSION_FIX)

message("* Debug : ${OPENSSL_VERSION_FIX}")

string(REGEX REPLACE "^0(.)" "\\1" OPENSSL_VERSION_MINOR "${OPENSSL_VERSION_MINOR}")
string(REGEX REPLACE "^0(.)" "\\1" OPENSSL_VERSION_FIX "${OPENSSL_VERSION_FIX}")

188: REGEX "^#define[\t ]+OPENSSL_VERSION_NUMBER[\t ]+0x[0-9][0-9][0-9][0-9][0-9][0-9].*"

Line 188 is apparently making a problem. Because of it $(openssl_version_str) is an empty string.

After I removed that line, OPENSSL_VERSION_MAJOR, OPENSSL_VERSION_MINOR, OPENSSL_VERSION_FIX had the correct version nubmers. That resolved most of the errors.

My theory at the moment is that there is a string parsing problem when OpenSSL changed form version 0.9.8 to 1.0.2

old line from opensslv.h:

#define OPENSSL_VERSION_NUMBER 0x009080bfL

new line form opensslv.h:

# define OPENSSL_VERSION_NUMBER 0x1000200fL

A new path error showed up after openssl version check passed:

CMake Error at cmake/macros/FindZMQ.cmake:72 (message):

/usr/include/openssl is the wrong location on your command by the looks of your screen shots, Its not detecting a version of openSSL during MAKE

"TrinityCore needs OpenSSL version 1.0.0 but found version .."

"-- Found OpenSSL library: OPENSSL_SSL_LIBRARIES-NOTFOUND;OPENSSL_CRYPTO_LIBRARIES-NOTFOUND"

I am aware that CMake is not detecting openSSL libraries during MAKE, i just don't know why.

/usr/include/openssl is the wrong location on your command by the looks of your screen shots, Its not detecting a version of openSSL during MAKE

The location is not wrong for headers. The problem is that it is not detecting OpenSSL libraries for some reason.

It should look like: " Found OpenSSL library: /usr/lib/i386-linux-gnu/libssl.so;/usr/lib/i386-linux-gnu/libcrypto.so "

TrinityCore needs OpenSSL version 1.0.0 but found version .."

I am using the latest version, don't know why it cant detect it.

-- Found OpenSSL library: OPENSSL_SSL_LIBRARIES-NOTFOUND;OPENSSL_CRYPTO_LIBRARIES-NOTFOUND"

As I mentioned in the post i am using "-DOPENSSL_LIBRARIES=/usr/lib/i386-linux-gnu/ " so it should find it

EDIT:
changed:

-DOPENSSL_INCLUDE_DIR=/usr/include/openssl

to

-DOPENSSL_INCLUDE_DIR=/usr/include/

First error was resolved:

CMake Error at cmake/macros/FindOpenSSL.cmake:188 (file):
file STRINGS file "/usr/include/openssl/openssl/opensslv.h" cannot be read.
Call Stack (most recent call first):
CMakeLists.txt:57 (find_package)

The rest remains the same.

I believe changing line 189 to

REGEX "^.*define[\t ]+OPENSSL_VERSION_NUMBER[\t ]+0x[0-9][0-9][0-9][0-9][0-9][0-9].*")

Fixes it, as it ignores the space between the # and the define, unlike the old regex
