openwrt 编译笔记_only have 0kb available on filesystem /overlay

错误一：

Creating filesystem with parameters:
    Size: 50331648
    Block size: 4096
    Blocks per group: 32768
    Inodes per group: 6000
    Inode size: 256
    Journal blocks: 0
    Label: 
    Blocks: 12288
    Block groups: 1
    Reserved blocks: 0
    Reserved block group size: 7
error: ext4_allocate_best_fit_partial: failed to allocate 13 blocks, out of space?
make[5]: *** [mkfs-ext4] Error 1

解决办法：

命令行执行  make menuconfig

找到"Target Images","Root filesystem partition size (in MB)"

把该项的值改大即可

错误二、Only have 0kb available on filesystem 编译错误

date:2018.3.9

使用df命令查看到磁盘没有可用空间

删除根目录下的无用资源，编译OK

错误三、

错误信息：Compressed data is corrupt

文件linux-firmware-2016-09-21-42ad5367.tar.xz有可能损坏，重新下载资源 https://sources.lede-project.org/

错误四：

缺少java环境

apt-get install openjdk-7-jdk

错误五：

在openWRT15.05项目根目录/staging_dir/toolchain-i386_i486_gcc-4.8-linaro_uClibc-0.9.33.2/include/目录下找到fpu_control.h

把该文件添加到openWRT17.01项目根目录/staging_dir/toolchain-i386_pentium4_gcc-5.4.0_musl-1.1.16/include/fpu_control.h

vim  ./staging_dir/toolchain-i386_pentium4_gcc-5.4.0_musl-1.1.16/include/fpu_control.h

错误六、

brctl文件重复

把busybox或bridge-utils-1.5中的brctl选择为不编译

我选择的是bridge不编译brctl

错误七：

把.config 文件中的CONFIG_PACKAGE_libustream-mbedtls=y进行屏蔽操作

#CONFIG_PACKAGE_libustream-mbedtls=y
