building dynamic lib with existing openssl

[clogwog]

I'm trying to build the sdk as a dynamic lib re-using the already install openssl like:

cmake -DBUILD_SHARED_LIBS=ON -DCMAKE_BUILD_TYPE="Debug" -DUSE_OPENSSL=ON ../aws-iot-device-sdk-cpp-v2

during which i see

-- Detected CMAKE_SYSTEM_PROCESSOR as aarch64
-- Detected 64-Bit system
-- The ASM compiler identification is GNU
-- Found assembler: /usr/bin/cc
-- Found crypto: /usr/lib/aarch64-linux-gnu/libcrypto.so

-- Configuring done

however when i make i eventually see an error like:

if i don't specify -DUSE_OPENSSL=ON the whole sdk builds and installs ok, but as soon as i try to use the libraries in another application i see a missing references to OPENSSL_free as well.

any hint on where to look ?

if i look at
crt/aws-crt-cpp/crt/aws-c-s3/samples/s3/CMakeFiles/s3.dir/link.txt it shows:

It looks like you might be missing -DCMAKE_INSTALL_PREFIX="<absolute path sdk-cpp-workspace dir>"

Also what OS are you trying to build this on?

[clogwog]

If I'm checking out the repository at

/home/jeteye/test/awsiotsdk

so i have the aws-iot-device-sdk-cpp-v2 right under that (/home/jeteye/test/awsiotsdk/aws-iot-device-sdk-cpp-v2 ) and i create a build directory like /home/jeteye/test/awsiotsdk/aws-iot-device-sdk-cpp-v2 what should be the DCMAKE_INSTALL_PREFIX ?

I've tried

jeteye@ljeteye:~/test/awsiotsdk/build$ cmake -DBUILD_SHARED_LIBS=ON -DCMAKE_BUILD_TYPE="Debug" -DUSE_OPENSSL=ON -DCMAKE_INSTALL_PREFIX="/home/jeteye/test/awsiotsdk" ../aws-iot-device-sdk-cpp-v2

and then call cmake --build . --target install

but it still has that problem. It may be related to something in my environment, just can't find what it is yet.

[clogwog]

after 2 days of searching found that I had an old openssl include directory located in /usr/local/include/openssl which got picked up before the libssl-dev package ones in /usr/include/openssl

it's working now.

thank you @jmklix for thinking along.
