IXSocketOpenSSL.cpp:(.text+0xe98): undefined reference to `SSL_get_peer_certificate' #305

Open squeaktoy opened 4 months ago

I build abaddon with the following command, and it fails with the following error during link-time. cmake -Bbuild -DCMAKE_BUILD_TYPE=RelWithDebInfo . && cmake --build build/ -j4:

what version is your openssl? i think it might be too old

i think cmake is picking up old openssl headers since SSL_get_peer_certificate is defined as SSL_get1_peer_certificate but thats not what the linker is seeing. you can check OPENSSL_INCLUDE_DIR in CMakeCache.txt to see what path contains the openssl headers and openssl/opensslv.h for the version of the headers

OPENSSL_INCLUDE_DIR:PATH=/usr/include

squeaktoy commented 4 months ago 
$ rg SSL_get_peer_certificate /usr/include/openssl/
/usr/include/openssl/ssl.h
1792:#   define SSL_get_peer_certificate SSL_get1_peer_certificate

As you can see it is defined, so it's strange why it's seemingly "undefined" when compiling abaddon

are there any other openssl packages installed? maybe im confusing myself but perhaps your install of ixwebsocket wants to link to openssl 1 but the build picked up openssl 3?
