# 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`
|
||||
|
||||
options should be:
|
||||
|
||||
- Target Options:
|
||||
- Target Architecture
|
||||
- MIPS (little endian)
|
||||
- Target Architecture Variant
|
||||
- Generic MIPS32R2
|
||||
- FP Mode
|
||||
- 32
|
||||
|
||||
- Build Options:
|
||||
- Strip Target Binaries [*]
|
||||
- Libraries
|
||||
- static only ( you can do dynamic if you like, just remember you have to copy ALL the program's required libararies to the device! )
|
||||
|
||||
|
||||
|
||||
- Toolchain
|
||||
- C library:
|
||||
- musl (you can also use uClibc-ng if you prefer)
|
||||
- Kernel Headers
|
||||
- Manually Specified Linux Version
|
||||
- 3.10.98
|
||||
- Custom Kernel Headers Series
|
||||
- 3.10.x
|
||||
- Binutils Version
|
||||
- 2.36.1
|
||||
- GCC Compiler Version
|
||||
- gcc 9.x
|
||||
- Enable C++ Support [*]
|
||||
- Enable compiler link-time-optimization support [*]
|
||||
|
||||
- Target packages
|
||||
- Whatever packages you want!
|
||||
|
||||
Then select exit, save changes, and then run `make` and your compiled programs should be in `output/target/usr/`
