yocto单独编译busybox

luoyaojun · ‎06-15-2020

使用yocto工程如何能够单独编译busybox，并生成新的ext4文件系统？

例如：

修改busybox中的源码文件：busybox-1.23.1/libbb/printable_string.c修改代码中某个函数，实现支持中文的显示。

修改完成后使用bitbake fsl-image-qt5并不能生成正确的busybox，如何操作才能正确重新编译busybox并生成我想要的文件系统？

当我使用bitbake -c compile -f busybox编译了busybox后再用命令bitbake fsl-image-qt5生成文件系统时报错:

/yocto/fsl-release-bsp/sources/poky/meta/recipes-core/busybox/busybox_1.23.1.bb.do_compile is tainted from a forced run

如何正确修改busybox源码，修改完成后能够正常重新打包文件系统(使用命令bitbake fsl-image-qt5)？

Hi luo yaojun,

We are able to recompile a busybox with yocto sumo (L4.14.98_2.0.0). Can you please try to recompile the busybox with a newer version?

Our configurations are:

Yocto sumo (L4.14.98_2.0.0)
Host system: ubuntu 16.04
Distro : fsl-imx-xwayland
Image: fsl-image-qt5-validation-imx

The steps which we have followed are as per below:

$ source setup-environment <build-directory>
$ bitbake fsl-image-qt5-validation-imx
Made changes in printable_string.c & unicode.c file from this link:
- linux busybox Chinese display modification instructions
To add support of Chinese characters you can refer the below link:
Building Qt5 Yocto Image with Turkish and Chinese characters?
$ vi conf/local.conf      (add the following two lines at the end to support Chinese)
    GLIBC_GENERATE_LOCALES = "zh_CN.UTF-8 en_GB.UTF-8 en_US.UTF-8"
    IMAGE_LINGUAS ?= "zh-cn"
$ bitbake -c compile busybox -f (recompile the busybox)
$ bitbake fsl-image-qt5-validation-imx -f (recompile your image with changes)
copy the .ttf of your fonts to the /usr/share/fonts/ttf/ in rootfs of your image.
Boot up the board with the image.
# vi /etc/profile (add the following line at the end)
export LANG=zh_CN.UTF-8
Open any text file containing Chinese font to verify.

Let us know in case of any concerns.

Regards,

Radhika Somaiya.

Hi luoyaojun,

You can take reference of the below link:

MACCHIATObin Wiki | Build from source - Buildroot

The Buildroot user manual (section 6.1.2 and 6.1.3)

I hope it can help you.

Regards,

Radhika Somaiya.

非常感谢，已成功实现中文支持。

你好，在哪里修改源码的，work路径下busybox吗，这边一直修改后busybox下的ls文件没有更新busybox是更新

luoyaojun · ‎06-18-2020

非常感谢！晚点我会验证这个BSP是否可行。

另外我想问下nxp有关于使用linaro的toolchain来编译buildroot的相关文档吗？

after "bitbake -c compile -f busybox", how about using "bitbake -f busybox"
