使用树莓派centos7 搭建arm-linux-gcc环境。
1. 上传文件到服务器。
2. 解压crosstool-0.43.tar.gz
tar xzf crosstool-0.43.tar.gz
3. 添加补丁文件
cp glibc-2.3.6-version-info.h_err.patch crosstool-0.43/patches/glibc-2.3.6/
4. 打补丁
patch -p1 < ../crosstool.patch
5. 修改demo-arm-softfloat.sh
vim demo-arm-softfloat.sh
6. 修改arm-softfloat.dat
vim arm-softfloat.dat
7. 修改all.sh
vim all.sh
8. 第一次编译
切换普通用户再切换root
./demo-arm-softfloat.sh
9. 编译出错
10. 修改Makefile
/home/kyj/Tools/create_crosstools/crosstool-0.43/build/arm-linux/gcc-3.4.5-glibc-2.3.6/glibc-2.3.6/manual
目录下Makefile
把：
chapters.% top-menu.%: libc-texinfo.sh $(texis) Makefile
AWK=$(AWK) $(SHELL) $< '$(chapters)' '$(add-chapters)' '$(appendices)'
修改成：
chapters.%: libc-texinfo.sh $(texis) Makefile
AWK=$(AWK) $(SHELL) $< '$(chapters)' '$(add-chapters)' '$(appendices)'
top-menu.%: libc-texinfo.sh $(texis) Makefile
AWK=$(AWK) $(SHELL) $< '$(chapters)' '$(add-chapters)' '$(appendices)'
把：
$(objpfx)stubs ../po/manual.pot $(objpfx)stamp%:
$(make-target-directory)
touch $@
修改成：
$(objpfx)stubs:
$(make-target-directory)
touch $@
../po/manual.pot:
$(make-target-directory)
touch $@
$(objpfx)stamp%:
$(make-target-directory)
touch $@
11. 修改all.sh
12. 重新编译
./demo-arm-softfloat.sh
13. 删除文件
rm /home/kyj/Tools/create_crosstools/crosstool-0.43/build/arm-linux/gcc-3.4.5-glibc-2.3.6/gcc-core-prefix/lib/gcc/arm-linux/3.4.5/libgcc_eh.a
rm /home/kyj/Tools/create_crosstools/crosstool-0.43/build/arm-linux/gcc-3.4.5-glibc-2.3.6/gcc-core-prefix/lib/gcc/arm-linux/3.4.5/libgcc_s.a
14. 重新编译
./demo-arm-softfloat.sh
