# build
|
|
|
|
two environments:
|
|
|
|
## atomcam tools (first)
|
|
|
|
`git clone https://github.com/mnakada/atomcam_tools`
|
|
|
|
`cd atomcam_tools`
|
|
|
|
`make`
|
|
|
|
then wait a long time for the development environment to compile and complete.
|
|
|
|
After its complete, run `docker-compose up -d` to start the docker instance.
|
|
|
|
To resume the instance, get the container ID from `docker ps`, and use `docker exec -it <container_Id> /bin/bash`
|
|
|
|
the following is translated from: [https://github.com/mnakada/atomcam_tools/blob/71a1214f83a92704221cedcf5101e12ba40f2f38/build.md?plain=1#L200](https://github.com/mnakada/atomcam_tools/blob/71a1214f83a92704221cedcf5101e12ba40f2f38/build.md?plain=1#L200)
|
|
|
|
|
|
|
|
### Docker environment
|
|
In the Docker environment, / src is mapped to atomcam_tools /.
|
|
|
|
Below, basically the commands in Docker are executed from the following Directory.
|
|
|
|
```
|
|
root@ac0375635c01: / atomtools # cd / atomtools / build / buildroot -2016.02
|
|
```
|
|
|
|
rootfs uses gcc in Docker in a glibc environment.
|
|
Gcc is also generated during build.
|
|
gcc prefix is
|
|
** / atomtools / build / buildroot-2016.02 / output / host / usr / bin / mipsel-ingenic-linux-gnu-**
|
|
is.
|
|
|
|
ATOM Cam's original system camera app iCamera_app is built in the uClibc environment.
|
|
|
|
Therefore, uClibc environment is required to build libcallback.so for hack of iCamera_app, so it is cloned separately.
|
|
** / atomtools / build / mips-gcc472-glibc216-64bit / bin / mips-linux-uclibc-gnu-**
|
|
using.
|
|
|
|
|
|
|
|
### How to build when making various changes
|
|
|
|
When changing the config of initramfs and kernel
|
|
|
|
```
|
|
root @ ac0375635c01: / atomtools # make linux-rebuild
|
|
root@ac0375635c01: / atomtools # cp output / images / uImage.lzma /src
|
|
```
|
|
|
|
Will be built with and copied to atomcam_tools /.
|
|
|
|
---
|
|
|
|
|
|
If you modify the files in rootfs or the menuconfig of busybox
|
|
```
|
|
root@ac0375635c01: / atomtools # make
|
|
root@ac0375635c01: / atomtools # cp output / images / rootfs.ext2 /src
|
|
```
|
|
|
|
Will be built with and copied to atomcam_tools /.
|
|
|
|
|
|
Copy it to the SD Card with the names factory_t31_ZMC6tiIDQN and rootfs_hack.ext2 respectively.
|
|
|
|
---
|
|
|
|
If you change the package included in rootfs
|
|
|
|
```
|
|
root @ ac0375635c01: / atomtools # make menuconfig
|
|
root @ ac0375635c01: / atomtools # make
|
|
```
|
|
|
|
Will build rootfs.
|
|
|
|
---
|
|
|
|
For individual package rebuilds
|
|
|
|
```
|
|
root @ ac0375635c01: / atomtools # make < package > -rebuild
|
|
```
|
|
|
|
---
|
|
|
|
When changing settings such as busybox commands
|
|
|
|
```
|
|
root @ ac0375635c01: / atomtools # make busybox-menuconfig
|
|
root @ ac0375635c01: / atomtools # make
|
|
```
|
|
|
|
Will build rootfs.
|
|
|
|
|
|
---
|
|
|
|
When changing kernel settings
|
|
|
|
```
|
|
root @ ac0375635c01: / atomtools # make linux-menuconfig
|
|
root @ ac0375635c01: / atomtools # make linux-rebuild
|
|
```
|
|
|
|
Will generate uImage.lzma.

|
## buildroot (second)
|
|
|
|
download `https://buildroot.org/downloads/buildroot-2022.05.tar.xz`
|
|
|
|
run `make menuconfig`
|
|
|
|

|
|
|
|
|
|
|
|
- Toolchain
|
|

|
|

|
|
|
|
Then select exit, save changes, and then run `make` and your compiled programs should be in `output/target/usr/`
