mangos>Segmentation fault (core dumped)

[Yogsoggoth]

Hi,

After compiling mangos two with different compiler I get the same error when using libcrypto.so.3 which is throwing me this error:

kernel: [ 1926.500759] mangosd[20040]: segfault at 78 ip 00007f6c04483ec8 sp 00007f6bf19789f0 error 4 in libcrypto.so.3[7f6c043a3000+25e000]

realmd works fine
mangosd starts, I can remote and pass commands see screenshot below.

This error occurs when I try to connect to the realm.

Env:
Ubuntu server 22.04.2 LTS (8cpu / 8Go ram)
kernel: Linux mangosvm 5.15.0-60-generic #66-Ubuntu 
Mangostwo sources: https://github.com/mangostwo/server 

Compiled 3 times with each of the following:

gcc-11.3 (error with vmap/TileAssembler.cpp:390:10: internal compiler error: in compute_live_loop_exits, at tree-ssa-loop-manip.c:247)
gcc-10: worked
clang-15: worked, mangosd and realmd are running with this version of the compiler

:/opt/wotlk/bin$

 

I tried with different options in CmakeLists.txt, but nothing works I even tried different libcrypto... same
Same error on my physical server as well where all db are running.

Any idea?

@Yogsoggoth You'll need to install OpenSSL 1.1.x, not OpenSSL 3.x. Ubuntu 22.04 ships with OpenSSL 3.x by default.
Follow this below and you'll be up and running in no time.

To remove OpenSSL 3.x

sudo apt remove openssl libssl-dev

Install OpenSSL 1.1.x

# download binary openssl packages from Impish builds
wget http://archive.ubuntu.com/ubuntu/pool/main/o/openssl/openssl_1.1.1f-1ubuntu2.19_amd64.deb
wget http://archive.ubuntu.com/ubuntu/pool/main/o/openssl/libssl-dev_1.1.1f-1ubuntu2.19_amd64.deb
wget http://archive.ubuntu.com/ubuntu/pool/main/o/openssl/libssl1.1_1.1.1f-1ubuntu2.19_amd64.deb

# install downloaded binary packages
sudo dpkg -i libssl1.1_1.1.1f-1ubuntu2.19_amd64.deb
sudo dpkg -i openssl_1.1.1f-1ubuntu2.19_amd64.deb
sudo dpkg -i libssl-dev_1.1.1f-1ubuntu2.19_amd64.deb
