編譯內核
- 配置menuconfig指令：
bitbake -c menuconfig -v linux-imx- 單獨編譯kernel、模塊、設備樹
bitbake -c compile -f -v linux-imx
bitbake linux-imx -c compile_kernelmodules -f -v
bitbake -c deploy -f -v linux-imx- 若要編譯文件系統則用下面總指令
bitbake core-image-minimal- 單獨編譯u-boot
bitbake -c compile -f -v u-boot-imx
bitbake -c deploy -f -v u-boot-imx
下面是使用Ubuntu 16.04遇到的ERROR:
1.

| #define mouse_trafo(y,x,to_screen) wmouse_trafo(stdscr,y,x,to_screen)
解決: 解決從源碼編譯ncurses6.0編譯lib_gen.c報錯的問題
搜索 curses.tail 文件. 將該文件中的註釋"/* generated /"刪除.
extern NCURSES_EXPORT(bool) mouse_trafo (int, int*, bool); /* generated */
然後刪除文件curses.h, 再編譯.
argp-help.o: In function `argp_fmtstream_write':
argp-help.c:(.text+0x1df0): multiple definition of `argp_fmtstream_write'
argp-fmtstream.o:argp-fmtstream.c:(.text+0x7a0): first defined here
argp-help.o: In function `argp_fmtstream_puts':
argp-help.c:(.text+0x1e40): multiple definition of `argp_fmtstream_puts'
argp-fmtstream.o:argp-fmtstream.c:(.text+0x860): first defined here
argp-help.o: In function `argp_fmtstream_putc':
argp-help.c:(.text+0x1eb0): multiple definition of `argp_fmtstream_putc'
argp-fmtstream.o:argp-fmtstream.c:(.text+0x800): first defined here
原因: argp-fmtstream.h 中 #define ARGP_FS_EI extern inline
extern inline在GNU89和C99標準中用法不同,這裏使用GNU89標準編譯
解決:
vim /home/okletsgo/work/tmp/fsl-release-bsp/build/tmp/work/x86_64-linux/cross-localedef-native/2.20-r0/build/Makefile
添加編譯參數 -std=gnu89
可以將cross-localedef-native提取出來編譯, 生成argp-fmtstream.o argp-help.o後替換進去
