QUESTION
I have cross compiled the library of paho-mqtt3a, which is normal before. I have corresponding libraries in the /usr/lib/ and /usr/local/lib directories, and I checked the details of the libraries with the file command. But why can't aarch64-linux-gnu/bin/ld find the paho-mqtt3a library today? I use these libraries:

QUESTION
I have been working on a C++ project which depends on RPLidar SDK. I have already installed the SDK as per the instructions in the README. (FYI: I couldn't install it in the /usr/local/
directory using sudo make install
command). As per the SDK documentation:
When developing via RPLIDAR SDK, developers only need to include SDK’s external header files (under sdk\include) into their own source code and link the application with SDK’s static library (rplidar_driver.lib or rplidar_driver.a).
So, in my CMakeLists.txt
, I have already added:

Answered 2020-Nov-24 at 00:32Since you already compiled the library, create an IMPORTED target that references the sdk/include

I am currently running Azerothcore via docker on my centos 7 server. I am trying to update it with the updates since i originally set it up.
current docker version:
Docker version 19.03.12, build 48a66213fe
current docker-compose version:
docker-compose version 1.18.0, build 8dd22a9
Here is the build command i ran:
./bin/acore-docker-build
When i run the docker build command i am getting the following errors:

Answered 2020-Sep-02 at 19:30i rebased my fork with the current master branch. Removed all the files in the src directory. Then did a git hard reset. Then ran git pull. Ran the remove build cache script again. Then kicked off another build. Build is working fine again with the current master branch. So i am guessing the issue was with my src directory not being in sync with the fork repo.
QUESTION
I'm getting undefined reference to dlsym@@GLIBC_2.2.5
even after linking it before and after the libraries. However in the linking output it appears that it's linking just before, but linking before all libraries should work, I guess.
ANSWER
Answered 2020-Jul-29 at 13:05Would you inspect carefully the actual command line used for linking, you will find that after libsmoltcp_cpp_interface_rust.a
, which has missed symbol, there is no -ldl
parameter.
It seems that in your case smoltcp_cpp
is an IMPORTED library target, which has libsmoltcp_cpp_interface_rust.a
as a link dependency (not as IMPORTED_LOCATION
property or so).
While CMake preserves order of the libraries, linked into a single binary (an or another library), order between dependencies of these libraries is not defined.
You need to add -ldl
as a link dependency for the smoltcp_cpp
target itself:
QUESTION
I have problems connecting to my TCP server socket. I have had it working before, but after adding threads I had problems compiling it with just g++ main.cpp
, and had to use a higher version, and after that it won't connect. The threads should really not mess with the execution of TCP connection. And it seems that it could be a compiler version or flag which is missing that could be the problem, but I'm not sure.
I have the firewall disabled, and have also tried with firewall on and accepting connections, but with no luck.
My client is returning the perror "Connection refused".
Wireshark packets show only two packets, which makes sense since the handshake is not complete.
I compile the server with g++ main.cpp -std=gnu++2a -pthread
and run it with ./a.out
, and compile the client with g++ testClientSocket.cpp -o testClient -std=gnu++2a -pthread
and run it with ./testClient
The server is called in another file with code:
...ANSWER
Answered 2020-Apr-15 at 21:55A bug here is that the server address is initialized after calling bind
. So its content are undefined at that call (and thus depend on the compiler, the OS, and phase of Moon). Most likely that’s the problem.
Also, SO_REUSEADDR
is set to zero (which means FALSE) in the code; that’s probably not what was meant, and may cause problems on quick restart.
QUESTION
I have a library which uses templates very much to avoid rewriting the same code many times . But as known this leads to horrible compile times and in visual studio also leads to heavy and slow intellisense which makes coding on a computer with 4 GB of ram very noisy .
However most classes are designed so that they only can be instantiated with particular types and templates are there to avoid rewriting for each type , this made me move most of the implementations to .cpp
files and use explicit template instantiation there .
For example I have :
...ANSWER
Answered 2020-Apr-08 at 15:38For anyone who comes to this question and looks for a solution to similar problem, this is what I ended with :
Instead of moving the implementation to a translation unit .cpp
and instantiating all templates there I put the implementation in an internal header file and removed the templates instantiations from the header . For each template instantiation I made a .cpp
file which includes the implementation header plus the underlying type interface and instantiate an instant of the class with this type .
Now each instantiation resides in its own file and the linker won't pull unused instants.
A drawback of this approach is the increased implementation files which are there only to go around this problem.

QUESTION
I'm following the guide from:
http://www.azerothcore.org/wiki/Installation
I'm having issues at the very last instructions under "compiling on windows" where I am asked to move a series of DLLs to a folder called CMAKE_INSTALL_PREFIX
. I cannot find this folder, despite getting no errors from the compiler? visual studio I don't think things are building properly.
I get 3 warnings when compiling in visual studio,
Warning LNK4221 This object file does not define any previously undefined public symbols, so it will not be used by and link operation that consumes this library scripts Build\src\server\scripts\zone_alterac_mountains.obj 1
Warning LNK4221 This object file does not define any previously undefined public symbols, so it will not be used by any link operation that consumes this library scripts \Build\src\server\scripts\zone_burning_steppes.obj 1
Warning C4715 'WorldSocket::ProcessIncoming': not all control paths return a value game c:\users\frith\azerothcore\src\server\game\server\worldsocket.cpp 727
I've restarted the entire process a few times and have made no progress. I'm under the impression I should see something in the destination folder, it is empty.
After some digging I found this in an error log in build/CMakefies
\Build\CMakeFiles\CMakeTmp\CheckIncludeFile.c(1): fatal error C1083: Cannot open include file: 'pthread.h': No such file or directory [\Build\CMakeFiles\CMakeTmp\cmTC_0e035.vcxproj]
I'm totally stuck.
...ANSWER
Answered 2020-Feb-19 at 13:34CMAKE_INSTALL_PREFIX
is the location where you selected to install AC.
As the guide says:
Change CMAKE_INSTALL_PREFIX to the location where you will run your server from.
this happens in chapter 3) Compiling
-> Compiling on Windows
