Building RPMs from Spec Files

Use this procedure to build Napatech driver and tools RPMs if you have modified the spec files.

About this task

The package installer yum is used in this example. You can of course use your distributions preferred RPM package installer.

Before you begin

rpm-build is required for building RPMs from SRPMs.

Kernel headers for the running kernel, gcc and make are required for building the nt-driver-3gd-modules RPM from nt-driver-3gd-x.y.z.build-short-sha1.src.rpm

Steps

To build RPMS from the spec files:

Procedure

Edit ~/rpmbuild/SPECS/nt-driver-3gd.spec and ~/rpmbuild/SPECS/nt-tools-3gd.spec to your liking.
Ensure that kernel headers for the running kernel and other prerequisites are installed:
```
$ sudo yum install kernel-devel-$(uname -r) gcc make rpm-build
```
If the Napatech driver has previously been installed on this host, install log files owned by root may be left in TMPDIR, by default /tmp. Remove these log files before building the Napatech driver as non-root user:
```
$ sudo rm -v /tmp/nt_driver_* /tmp/nt_tools_*
```

Build the RPMs:

$ rpmbuild -bb ~/rpmbuild/SPECS/nt-driver-3gd.spec
$ rpmbuild -bb ~/rpmbuild/SPECS/nt-tools-3gd.spec

Results

By default, the resulting RPMs are located in ~/rpmbuild/RPMS. For example:

In addition, the build process leaves some log files in TMPDIR, by default /tmp:

/tmp

├── nt_driver_3gd.log.clip
└── nt_tools_3gd.log
