编译buildroot时，makedev dev/console, file exist.

一开始编译时没给root权限，直接make,执行到这里报错：

rootdir=/home/any/MPU/Nuvoton/nuc970bsp/20200318/NUC970_Buildroot/output/target
table='/home/any/MPU/Nuvoton/nuc970bsp/20200318/NUC970_Buildroot/output/build/_device_table.txt'
makedevs: line 23: can't create node /home/any/MPU/Nuvoton/nuc970bsp/20200318/NUC970_Buildroot/output/target/dev/console: Operation not permitted
make[1]: ***

然后给root权限，结果 sudo make还是报错，

rootdir=/home/any/MPU/Nuvoton/nuc970bsp/20200318/NUC970_Buildroot/output/target
table='/home/any/MPU/Nuvoton/nuc970bsp/20200318/NUC970_Buildroot/output/build/_device_table.txt'
makdev : line23: can't creat node /home/buidlroot/output/target/dev/console  file exists.

完整的make记录，可以看到是make时创建了_fakeroot.fs和_device_table.txt文件，并往里输入了内容。

Re: 编译buildroot时，makedev dev/console, file exist.

手动输入报错前的命令，先是fakeroot，执行后，命令提示符由$变为#。

PATH="/home/any/MPU/Nuvoton/nuc970bsp/NUC970_Buildroot/output/host/bin:/home/any/MPU/Nuvoton/nuc970bsp/NUC970_Buildroot/output/host/sbin:/home/any/MPU/Nuvoton/nuc970bsp/NUC970_Buildroot/output/host/usr/bin:/home/any/MPU/Nuvoton/nuc970bsp/NUC970_Buildroot/output/host/usr/sbin:/opt/Qt/5.13.2/gcc_64/bin:/usr/local/arm_gcc/arm_linux_gcc_12/bin:/home/any/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/snap/bin" /home/any/MPU/Nuvoton/nuc970bsp/NUC970_Buildroot/output/host/usr/bin/fakeroot

再执行_fakeroot.fs，结果报错，打开_fakeroot.fs，从后往前以此注释掉再运行，发现是这一行引起的报错：

/home/any/MPU/Nuvoton/nuc970bsp/NUC970_Buildroot/output/host/usr/bin/makedevs -d /home/any/MPU/Nuvoton/nuc970bsp/NUC970_Buildroot/output/build/_device_table.txt /home/any/MPU/Nuvoton/nuc970bsp/NUC970_Buildroot/output/target

搜makedevs用法，  makdevs -d 文件  -r 路径，那么就是在buildroot/output/target目录下，创建_device_table.txt文件里写好的目录。
创建节点需要root权限，可上一步执行的fakeroot，就是为了避免用ubuntu系统的root权限啊。那么这里为何又提示权限不够？

Re: 编译buildroot时，makedev dev/console, file exist.

注释掉_device_table.txt里/dev/conslole那一行，再编译，遇到了LD_PRELOAD 里找不到libfakroot.so的报错，在output/target里搜了下，确实没有。
感觉fakeroot编译可能有问题。昨天编译fakeroot遇到个问题，有个宏定义没有，去git.buildroot.org找到fakeroot这个文件，看到002xxx.patch是解决这个问题的，就下载了这个，编译通过。
除了001，002.patch，还有003-005.patch，今天索性全下载下来，放到buidlroot/package/fakeroot目录下。再次编译，居然通过了。

总结一下，新塘提供的nuc972 bsp在ubuntu18.04下编译很顺利。
在ubunt22.04下编译，遇到了几个问题，基本大都是通过在git.buildroot.org下找对应的patch解决的。
那个c++17下bool变量不能用++运算符是手动改成类似 a = a+1 来解决的。

Re: 编译buildroot时，makedev dev/console, file exist.

本人水平太菜，不敢轻易动，怕引起更多的错误出来。庆幸buildroot总算是编译完成了。

Re: 编译buildroot时，makedev dev/console, file exist.

执行install_nuc970_bsp.sh时，遇到了这么个报错，根据报错内容找到.sh里对应的一行，就是解压output/images/rootfs.tar文件。
解压到/dev/console报错，而且/dev/consle文件类型为“未知”.

tar ./dev/console 无法mknod 无效的参数

手动解压rootfs.tar，解压出来的文件里，确实没有/dev/console。

还有个报错：

fseterr.c:77:3: error: #error "Please port gnulib fseterr.c to your platform! Look at the definition

网上搜到的，这么输入后不报错了，进入output/build/host-bisonxxx：

sed -i 's/IO_ftrylockfile/IO_EOF_SEEN/' lib/*.c
echo "#define _IO_IN_BACKUP 0x100" >> lib/stdio-impl.h
