I followed the introduction to build this project. But I always get many errors like these

Can you tell me the version of your operating system and the steps you followed?
Looks like it lacks a dependency on randomx. You can check if randomx is installed.
If you can tell me more detailed information, I can try to help you solve this problem

[bigliam]

@MyronX Emmm. The system is [Linux version 3.10.0-957.el7.x86_64] in a k8s container. And I checked the randomx.h file. It is under the path:[/usr/local/include/randomx.h]. So I guess randomx.h is correctly installed. What is more, I followed the instructions by "cd client && make" command.

Here is information when installing randomx:
[ 86%] Built target randomx
[ 93%] Built target randomx-benchmark
[ 96%] Built target randomx-codegen
[100%] Built target randomx-tests
Install the project...
-- Install configuration: "Release"
-- Installing: /usr/local/lib64/librandomx.a
-- Up-to-date: /usr/local/include/randomx.h

maybe u use centos？
try this to build randomx

git clone https://github.com/tevador/RandomX.git
cd RandomX
mkdir build && cd build
cmake -DARCH=native ..
make
sudo make install

and try to open hugepage for randomx

• Temporary open

sudo sysctl -w vm.nr_hugepages=2560

• Permanent open

sudo bash -c "echo vm.nr_hugepages=2560 >> /etc/sysctl.conf"

then reboot system

See if this method solves your problem

I do actually build randomx in this way. Maybe rebooting is the key.

ok. Waiting for your feedback

@MyronX I'm facing the same issue, but after I set hugepages and restart my machine, it is still not working.
