After completing the build, the binaries are available in the `cmake_targets/ran_build/build` directory. A copy is also available in the `target/bin` directory, with all binaries suffixed by the 3GPP release number, today .Rel15.
When installing the pre-requisites, especially the `UHD` driver, you can now specify if you want to install from source or not.
## Installing UHD from source
Previously for Ubuntu distributions, when installing the pre-requisites, most of the packages are installed from PPA.
Especially the `UHD` driver, but you could not easily manage the version of `libuhd` that will be installed.
Now, when installing the pre-requisites, especially the `UHD` driver, you can now specify if you want to install from source or not.
- For `fedora`-based OS, it was already the case all the time. But now you can specify which version to install.
- For `ubuntu` OS, the Ettus PPA currently installs the following versions:
* `Ubuntu16.04`: --> version `3.15.0.0`
* `Ubuntu18.04`: --> version `4.1.0.0`
- For `ubuntu` OS, you can still install from the Ettus PPA or select a version to install from source.
* In case of PPA installation, you do nothing special, the script will install the latest version available on the PPA.
- `./build_oai -I -w USRP`
* In case of a installation from source, you do as followed:
```bash
export BUILD_UHD_FROM_SOURCE=True

## Issue when building `nasmeh` module ##
**CAUTION: Note that if you are using the OAI eNB in TDD mode with B2xx boards, a patch is mandatory.**
A lot of users and contributors have faced the issue: `nasmesh` module does not build.
Starting this commit, the patch is applied automatically in our automated builds.
The reason is that the linux headers are not properly installed. For example:
See:
```bash
$ uname -r
4.4.0-145-lowlatency
$ dpkg --list | grep 4.4.0-145-lowlatency | grep headers
ii linux-headers-4.4.0-145-lowlatency 4.4.0-145.171
```
In my example it is properly installed.
Check on your environment:
```bash
$ uname -r
your-version
$ dpkg --list | grep your-version | grep headers
$
```
Install it:
```bash
$ sudo apt-get install --yes linux-headers-your-version
```
On CentOS or RedHat Entreprise Linux:
```bash
$ uname -r
3.10.0-1062.9.1.rt56.1033.el7.x86_64
$ yum list installed | grep kernel | grep devel
kernel-devel.x86_64 3.10.0-1062.9.1.el7 @rhel-7-server-rpms
kernel-rt-devel.x86_64 3.10.0-1062.9.1.rt56.1033.el7
```
If your kernel is generic, install `kernel-devel` package: `sudo yum install kernel-devel`
In most case, your kernel is real-time. Install `kernel-rt-devel` package: `sudo yum install kernel-rt-devel`
