最近买了itop-4412 的板子 准被从内核移植 驱动编写 应用编程重新走一遍,刚开始很多问题没有搞懂,导致下面一些问题,后面会整理从0编译的文档 Makefile:506: arch//Makefile: No such file or directory make: *** No rule to make target 'arch//Makefile'. Stop. ARCH?= $(SUBARCH) 这里不能修改成 ARCH?= $(arm) Makefile中 $是递归展开 如果arm在之前没有定义 则ARCH展开为空 应该改为ARCH?= arm gcc: error: unrecognized argument in option ‘-mabi=aapcs-linux’ gcc: note: valid arguments to ‘-mabi=’ are: ms sysv gcc: error: unrecognized command line option ‘-mlittle-endian’ gcc: error: unrecognized command line option ‘-mno-thumb-interwork’ gcc: error: unrecognized command line option ‘-mfpu=vfp’ Kbuild:21: recipe for target 'kernel/bounds.s' failed make[1]: *** [kernel/bounds.s] Error 1 Makefile:1097: recipe for target 'prepare0' failed make: *** [prepare0] Error 2 CROSS_COMPLIE?= /home/cjx/Linux/Linux/LinuxTool/CompileTool/arm-2009q3/bin/arm-none-linux- gnueabi-
这个问题是猜测是由于编译器OABI ,而我下载最新的内核是只支持EABI的编译器 所以没法通过,所以我又下载 了3.1的版本来编译,去掉内核中的Kernel Features->Use the ARM EABIto compile the kernel选项
cc1: error: unrecognized command line option "-fstack-protector-strong" Kbuild:35: recipe for target 'kernel/bounds.s' failed make[1]: *** [kernel/bounds.s] Error 1 Makefile:980: recipe for target 'prepare0' failed make: *** [prepare0] Error 2 这是由于编译器太老的原因 换个编译器 重新修改下Makefile编译器路径
fixdep: error opening depfile: kernel/.bounds.s.d: No such file or directory Kbuild:35: recipe for target 'kernel/bounds.s' failed make[1]: *** [kernel/bounds.s] Error 2 Makefile:980: recipe for target 'prepare0' failed make: *** [prepare0] Error 2 有人说还是编译器不兼容内核的原因 可以查Documentation/Changes 看内核需要最低版本的编译器 Gnu C 3.2 # gcc --version 换了4.4.3的版本还是不行 bounds.c里面是个跳跃函数 这里看问题的描述是在Kbuild的35行,Kbuild是内核的配置文件,这里看出bounds.s 是由bounds.c生成的, 但是为什么生成不了呢,最后想想还是编译器不行,又把下载了3.3.2的版本,编译又出现下面的问题
error: unrecognized command line option '-fstack-protector-strong 解决办法: 在kernel目录下: make menuconfig 在 General setup—— Optimize very unlikely/likely branches 把该项在编译该项中去掉。如下图: 或者把子选项Stack Protector buffer overflow detection 设置为None 接着编译 Assembler messages: Error: unknown architecture `armv7-a'
scripts/Makefile.build:257: recipe for target 'scripts/mod/empty.o' failed make[2]: *** [scripts/mod/empty.o] Error 1 scripts/Makefile.build:402: recipe for target 'scripts/mod' failed make[1]: *** [scripts/mod] Error 2 Makefile:555: recipe for target 'scripts' failed make: *** [scripts] Error 2 这应该是menuconfig没有配置好的原因, 在System Type中选择Samsung S3C24XX SoCs /home/cjx/usr/local/arm/3.3.2/bin/../lib/gcc-lib/arm-linux/3.3.2/../../../../arm-linux/bin/as: unrecognized option '-gdwarf-2' scripts/Makefile.build:293: recipe for target 'usr/initramfs_data.o' failed make[1]: *** [usr/initramfs_data.o] Error 1 Makefile:937: recipe for target 'usr' failed make: *** [usr] Error 2 这里看还是gcc有问题 没有 gdwarf-2 的选项 最终又换了编译器通过,后续要分析下编译器与内核的关系CHK include/config/kernel.releaseCannot use CONFIG_CC_STACKPROTECTOR_STRONG: -fstack-protector-strong not supported by compilerMakefile:1090: recipe for target 'prepare-compiler-check' failedmake: *** [prepare-compiler-check] Error 1说明编译器不支持更强的堆栈保护,在 >General setup->Stack Protector buffer overflow detection (Regular) --->改成Regular这个变量在arch/Kconfig里面 |
