Compilation and Installation

Use PuTTY to log in to the server as the root user.
Decompress the source package.
```
tar zxvf maker-2.31.11.tgz
```
Go to the directory generated after the decompression.
```
cd maker
```
Go to the source code directory and configure MPI.
```
cd src
perl Build.PL
```
During the configuration process, when the system asks you whether to support MPI, select Yes. If the MPICH environment variable has been loaded, the system automatically identifies the environment variable.
Install the Perl package through CPAN.
```
yum install perl-CPAN
./Build installdeps
```
During the installation process, when the system asks you whether to install DBD::Pg, select No. If the PostgreSQL database has been configured, select Yes.
Install MAKER.
```
./Build install
```
The executable file is generated in the bin directory of the source code root directory. Run the following command to add the file to environment variables:
```
export PATH=/path/to/maker/bin:$PATH
```
