Problems building

[et4te]

After cloning and running ./install.sh and adding path to LD_LIBRARY_PATH, build attempt:

~/cpp/chaos$ g++ -std=c++11 main.cpp -I/usr/local/include/chaos/ -lchaos
/tmp/ccEHIRQi.o: In function `main':
main.cpp:(.text+0x2c): undefined reference to `chaos::engines::xorring64::push(unsigned long)'
main.cpp:(.text+0x42): undefined reference to `chaos::engines::xorring64::push(unsigned long)'
main.cpp:(.text+0x55): undefined reference to `chaos::engines::xorring64::pull()'
/tmp/ccEHIRQi.o: In function `chaos::machine<chaos::engines::xorring64>::reset()':
main.cpp:(.text._ZN5chaos7machineINS_7engines9xorring64EE5resetEv[_ZN5chaos7machineINS_7engines9xorring64EE5resetEv]+0x3c): undefined reference to `chaos::engines::xorring64::__reset()'
collect2: error: ld returned 1 exit status

Using the following code:

#include <iostream>
#include <chaos.h>

CHAOS_MACHINE_XORRING64 machine;

int main(void) {
  machine.set_space(100000);
  machine.push(0x8a5cd789635d2dff);    // add some data
  machine.push(0x284600e3f30e38c3);     // and other...
  while (true) putc_unlocked(machine.pull(), stdout);
}

Could you paste/do:

1. g++ --version; cmake --version and compare with https://travis-ci.org/maciejczyzewski/libchaos (working version). Try to update your cmake if possible.
2. ls /usr/local/include/chaos/ (just check if it's correctly installed)
3. replace #include <chaos.h> to:

#include <chaos/types.hh>
#include <chaos/macros.hh>
#include <chaos/seed.hh>
#include <chaos/machine.hh>
#include <chaos/engines/xorring.hh>

With modified headers I still get the same error.

It is a linking error, you should specify the directory where libchaos library objects are installed. For example, if it is installed in /usr/local/lib the compilation flag is: -L/usr/local/lib/, so the whole command looks like it: g++ -std=c++11 main.cpp -I/usr/local/include/chaos/ -L/usr/local/lib/ -lchaos

same problems here~~ I've tried all methods above but still get same error... I think the only different is:
I need to use sudo ./install.sh to install

Others such as path, comment and example are the same...
Is because I use sudo?? If yes, how can I install without sudo and without getting a permission denied error?? Or there are some other way to make it work??

Please help me... QAQ Thanks

У меня такая же ошибка, компоновщик тела методов не находит
Ошибка и на моей машине и при сборке на сервере
ОС: KUbuntu самой новой версии
g++ version 13.2.0
cmake version 3.27.4
А эта библиотека подойдёт для генерации случайных значений в криптографических целях?

Без sudo выдаёт ошибку доступа
С sudo установилось, но ошибка компоновщика, о чём выше идёт речь
