How to add my own binaries into buildroot?

[lvcargnini]

Hi,

Please, how do I add my own binaries into the image created by buildroot? Or How do I add my code to be compiled and inserted into the create image? I have my own set of benchmarks I would like to add into the image to test in x86_64 and Aarch64 later on.

Hi Vitorio, sorry for late reply!

Have a look at these pointers:

• https://github.com/cirosantilli/linux-kernel-module-cheat/tree/105c506ac639e89318621f7df89609f0c9525f26#add-new-buildroot-packages
• https://github.com/cirosantilli/linux-kernel-module-cheat/commit/ecaccfd8d0e550b3ec79dd3a2bc9363249e304db

You can then just copy your binaries into TARGET_DIR instead of compiling them.

But don't forget that they must have been compiled with -static.

Let me know if something is not clear.

Thanks will do that, also found the hello package in here: https://github.com/cirosantilli/buildroot/tree/in-tree-package-2016.05

Hi,

I got the binary into the image, just keep in mind, delete the image file, then the image it is built with the additional binary, otherwise the 'overwrite' it is not really working. Despite of that, I try to run my app and the only thing that I see it is the following:

memtest

[ 52.955072] serial8250: too much work for irq4 memtest sh: memtest: not found

/usr/bin/memtest

[ 67.023025] serial8250: too much work for irq4 /usr/bin/memtest sh: /usr/bin/memtest: not found

however the app it is there in /usr/bin once I list it.

too much work for irq4

I've seen this, I don't kon't know how to solve it, but it did not affect my results.

sh: memtest: not found

You haven't compiled the clang binary with -static. The message is misleading, what it can't find is the dynamic loader.

E.g. try on host file /bin/ls, which gives interpreter /lib64/ld-linux-x86-64.so.2,.

As you can see no, but I let it compile using GCC, will revert to clang and create a static binary, thanks.
