Hello, I'm trying to build the pjsua2-test-app for arm and  I encounter an error : arm-openstlinux_weston-linux-gnueabi-ld: /local/STM32MP15-Ecosystem-v1.0.0/Developer-Package/Lab-DeveloperPackage/pjproject-2.9/pjsip/build/../src/pjsua2/account.cpp:1089: undefined reference to `__dso_handle' Where should be defined __dso_handle and why I'm getting this error? Thank you.
