Compile error on Ubuntu22.04

[xianglingzhang]

Hi, I try to build liboqs on Ubuntu22.04

$ cmake -GNinja -DOQS_USE_OPENSSL=ON -DBUILD_SHARED_LIBS=ON -DCMAKE_INSTALL_PREFIX=/usr -DOPENSSL_ROOT_DIR=/usr/local/ssl/lib/ ..

I get this error.

Hi @xianglingzhang, that build error should arise when the OQS_DEBUG_BUILD variable is set and CMAKE_BUILD_TYPE is not: see https://github.com/open-quantum-safe/liboqs/blob/9c8db18ec164492c352fe5748a8badc9f4ce3156/tests/system_info.c#L279

Are you by any chance setting the OQS_DEBUG_BUILD variable anywhere?

I also see from the logs that you have local modifications. If you could provide more information about your system and liboqs setup, I can try to duplicate the issue.
