The main content of this article is to explain "what is the way to add buildroot to support third-party software", interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Next, let the editor take you to learn "what is the way to add buildroot to support third-party software?"

When we use the development board to run our own programs, we may need the file system to provide some third-party library files and software, such as alsa-lib, alsa-utils,mplayer,opencv and so on. We can enable these software and libraries through buildroot configuration. Most of them are in the "Target packages" option of the configuration interface.

1 enable Alsa-lib

First of all, through the command "make menuconfig" configuration, open the configuration interface, the key down to find the "Target packages" and enter. As shown in figure 1.1:

Then scroll down the arrow key to find the "Libraries" option and enter. As shown in figure 1.2:

Then find "Audio/Sound" and enter. As shown in figure 1.3:

Then find "alsa-lib", select the space and enter. As shown in figure 1.4:

Then select all the spaces on this page, as shown in figure 1.5:

Finally save and exit.

2 enable Alsa-utils

First of all, through the command "make menuconfig" configuration, open the configuration interface, the key down to find the "Target packages" and enter. As shown in figure 2.1:

Then use the arrow keys to flip down to find "Audio and video applications", enter. As shown in figure 2.2:

Then find "alsa-utils", select the space, and enter.

Finally, select all the software spaces on the page, as shown in figure 2.4:

Finally save and exit.

Then we use the command "make" to compile buildroot, during which he will download some software source code, please make sure the network is available. As shown in figure 2.5:

Wait for the compilation to complete so that you can use these libraries and software directly in the development board system. Users of other required software environments can be configured as appropriate. Of course, the source code of these libraries and software is also downloaded from the network during the compilation process, so make sure that the network state of the virtual machine is networked.

At this point, I believe you have a deeper understanding of "what is the way to add buildroot to support third-party software?" you might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
