Installing HDF5

If the configure file in the source packages of the HDF5 components specifies that the GNU software optimization level is O3, add the following optimization options before performing 1. For details, see 4.
```
export optflags="-O3"
export ldflags="-Wl,--build-id"
export threads=$(nproc)
```

If the configure file specifies that non-GNU software optimization is not required, you do not need to add optimization options.

Procedure

Use PuTTY to log in to the server as the root user.
Decompress the HDF5 installation package.
```
tar -zxvf hdf5-1.10.5.tar.gz
```
Go to the directory generated after the decompression.
```
cd hdf5-1.10.5
```

Perform the configuration.

Apply the patch package.
```
patch -p1 < libtool.patch
```

Create a libtool.patch file and edit the file.

Create a libtool.patch file.
```
vi libtool.patch
```
