Problems occur when cross-compiling using wolfssl-5.6.3 to replace openssl-1.1.0

[itmanlee]

1. On the mstar621q platform, complete the cross-compilation of wolfssl5.6.3. The configure execution command is as follows:

step1:
./configure --prefix=/home/lishiyong/wolfssl-5.6.3/arm-buildroot-linux-uclibcgnueabihf --host=arm-linux CC=arm-buildroot-linux-uclibcgnueabihf-gcc AR=arm-buildroot-linux -uclibcgnueabihf-ar STRIP=arm-buildroot-linux-uclibcgnueabihf-strip RANLIB=arm-buildroot-linux-uclibcgnueabihf-ranlib ARCHFLAGS="-ffunction-sections -fdata-sections -Wl,--gc-sections" --enable- dtls --enable-32bit --enable-opensslextra --enable-all-crypto --enable-static --disable-shared --host=arm-linux

step2:
make && make install

2. Compile aws-iot-device-sdk-embedded-C with the following command:

step1:
cmake -S . -Bbuild -DAWS_IOT_ENDPOINT="xxxxxx-xxxx.iot.ap-southeast-1.amazonaws.com" -DROOT_CA_CERT_PATH="/ants_config/hostmgr_autoupgrade/AmazonRootCA1.pem" -DCLIENT_CERT_PATH="/ants_config/hostmgr_autoupgrade/iot- devices.pem.crt" -DCLIENT_PRIVATE_KEY_PATH="/ants_config/hostmgr_autoupgrade/private.pem.key" -DTHING_NAME="test-ipcam-20231027" -DOPENSSL_ROOT_DIR=/home/lishiyong/wolfssl-5.6.3/arm-buildroot-linux -uclibcgnueabihf -DOPENSSL_INCLUDE_DIR=/home/lishiyong/wolfssl-5.6.3/arm-buildroot-linux-uclibcgnueabihf/include/wolfssl -DOPENSSL_LIBRARIES=/home/lishiyong/wolfssl-5.6.3/arm-buildroot-linux-uclibcgnueabihf/lib -DOPENSSL_CRYPTO_LIBRARY=/home/lishiyong/wolfssl-5.6.3/arm-buildroot-linux-uclibcgnueabihf/lib/libwolfssl.a -DOPENSSL_SSL_LIBRARY=/home/lishiyong/wolfssl-5.6.3/arm-buildroot-linux-uclibcgnueabihf/lib /libwolfssl.a -DCMAKE_TOOLCHAIN_FILE=/opt/mstar-linux/x86-arm/arm-buildroot-linux-uclibcgnueabihf-4.9.4-uclibc-1.0.31/share/buildroot/toolchainfile.cmake -DBUILD_SHARED_LIBS=OFF -DCMAKE_INSTALL_PREFIX= /home/lishiyong/aws-iot/arm-buildroot-linux-uclibcgnueabihf && cd build

step2: make

An error occurred when executing step 2, as shown in the figure below

Please see if you can help me solve this problem

Hi @itmanlee
Thanks for question. Currently, wolfssl is not supported. If you want to use wolfssl, you need to implement something like this https://github.com/aws/aws-iot-device-sdk-embedded-C/blob/main/platform/posix/transport/src/openssl_posix.c
