[SOLVED] Centos 8: /usr/lib64/libgmp.so: File format not recognized

When I run ./make_devel.sh on centos 8, I get this error:

Thank you for your prompt response, Already tried that, but it seems those packages are for CentOS 7, On CentOS 8 I get:

# yum install cmake3 gmp-devel libsodium gmp-static libsodium-static

did you add in the extended "yum" repositories?

[ataa]

Which repos are your referring too?

[Hardcore-fs]

Since i don't work with centos8 only 7.... Google is your friend....

[ataa]

Yes, I have Epel and Elrepo but gmp-static rpm for centos 8 is not available on any repo. I installed cmake manually but I don't know how to install gmp-static. The error "/usr/bin/ar: /usr/lib64/libgmp.so: File format not recognized" seems to be related to that missing package.

[Hardcore-fs]

ok so pull the git repository for that source & build from scratch. also note.... you can find an RPM package for another platform ubuntu and usually it will go in.

but centos8 is DEAD in the water.... everyone is abandoning it....

Jesus... why link to google thinking you are helping... Here is how to get it install on CentOS/RHEL/Rocky Linux 8 . You have to statically compile CMAKE and GMP

cd /tmp
wget https://github.com/Kitware/CMake/releases/download/v3.20.3/cmake-3.20.3.tar.gz
tar -xvf cmake-3.20.3.tar.gz
cd cmake-3.20.3
./bootstrap 
make 
make install
sudo dnf install lzip -y 

cd /tmp
wget https://gmplib.org/download/gmp/gmp-6.2.1.tar.lz
tar -xvf gmp-6.2.1.tar.lz
cd gmp-6.2.1
./configure
make 
make install

echo PATH=$PATH:/usr/local/bin/ # for statically compiled cmake if not already in your PATH
ln -sf /usr/local/lib/libgmp.so.10.4.1 /usr/lib64/libgmp.so

git clone https://github.com/dendil/chia-plotter.git
cd chia-plotter
git submodule update --init
./make_devel.sh

[madMAx43v3r]

I disabled usage of GMP in latest master ./make_devel.sh, if it works I will disable in all make scripts.

[madMAx43v3r]

you have to uninstall libgmp-dev from system also

Because...... i had to do the research for myself.... plus this is already covered in other threads, so people cannot even be bothered to read the other threads.

then you get people on here who cannot even be bothered to say thanks.... all they do is come into the forum with some sort of exotic build and expect others to give answers rather than standardizing their build to the group., all they care about is themselves.

Thank you, now that issue has been resolved, but I get different error now:

Is it safe to ignore? the binary is working just fine. I will check the resulting plot with chia plots check and report back.

Thanks.

[Hardcore-fs]

lazy programmer... it needs a cast. ignore for now....

Yes that should be fine to ignore. Everybody gets those warnings by the looks of it.

Thanks everyone, I managed to build the plotter on CentOS 8.3. Started the plotter last night, finished 20 Plots, all of them passed "chia plots check".
