从放弃到入门[二] 海思Hi3516EV200 SDK初体验

1.编译环境：Ubuntu20.04

2.编译链：arm-himix100-linux

3.环境依赖：

sudo apt-get install make libc6:i386 lib32z1 lib32stdc++6 zlib1g-dev libncurses5-dev ncurses-term libncursesw5-dev g++ texinfo texlive gawk libssl-dev openssl bc u-boot-tools libuuid1:i386 gperf bison zlib1g-dev liblzo2-dev uuid-dev pkg-config

4.SDK版本：

Hi3516EV200R001C01SPC011

5.编译准备：

先执行脚本：sdk.unpack 给SDK解包

由于开源工具的整改，SDK对于部分开源工具不在提供源码包，所以我们需要自行下载处理。需要处理的源码包在SDK包的osdrv下面的readme都有说明。为了偷懒，写了一个简单的补丁脚本来处理这些。

这里有些和osdrv下readme有差异的地方会在后面说明原由。

6.编译：

在osdrv下进行整包编译：

make OSDRV_CROSS=arm-himix100-linux CHIP=hi3516ev200 all

在ubuntu14.04中可以直接编译过，但是在18.04和20.04中可能会遇到以下错误。

错误一：

fseeko.c: In function 'rpl_fseeko':`

`fseeko.c:110:4: error: #error "Please port gnulib fseeko.c to your platform! Look at the code in fseeko.c, then report this to bug-gnulib."`

 `110 |  #error "Please port gnulib fseeko.c to your platform! Look at the code in fseeko.c, then report this to bug-gnulib."`

   `|  ^~~~~`

 `CC    printf-args.o`

 `CC    printf.o`

`make[5]: *** [Makefile:1696: fseeko.o] Error 1`

`make[5]: *** Waiting for unfinished jobs....`

 `CC    printf-parse.o`

`fseterr.c: In function 'fseterr':`

`fseterr.c:78:3: error: #error "Please port gnulib fseterr.c to your platform! Look at the definitions of ferror and clearerr on your system, then report this to bug-gnulib."`

  `78 | #error "Please port gnulib fseterr.c to your platform! Look at the definitions of ferror and clearerr on your system, then report this to bug-gnulib."`

   `|  ^~~~~

解决方法：

修改：osdrv/tools/pc/hi_gzip/Makefile：

pushd gzip-1.8;patch -p1 < ../hi_gzip.patch;./configure;make -j12;popd

改为：

pushd gzip-1.8;patch -p1 < ../hi_gzip.patch;sed -i 's/IO_ftrylockfile/IO_EOF_SEEN/' lib/*.c;echo "#define _IO_IN_BACKUP 0x100" >> lib/stdio-impl.h;./configure;make -j12;popd

错误二：

mksquashfs.c: In function ‘create_inode’:`

`mksquashfs.c:987:24: error: called object ‘major’ is not a function or function pointer`

 `987 |  unsigned int major = major(buf->st_rdev);`

   `|            ^~~~~`

`mksquashfs.c:987:16: note: declared here`

 `987 |  unsigned int major = major(buf->st_rdev);`

   `|        ^~~~~`

`mksquashfs.c:988:24: error: called object ‘minor’ is not a function or function pointer`

 `988 |  unsigned int minor = minor(buf->st_rdev);`

   `|            ^~~~~`

`mksquashfs.c:988:16: note: declared here`

 `988 |  unsigned int minor = minor(buf->st_rdev);`

   `|        ^~~~~`

`mksquashfs.c:1011:24: error: called object ‘major’ is not a function or function pointer`

 `1011 |  unsigned int major = major(buf->st_rdev);`

x   `|            ^~~~~`

`mksquashfs.c:1011:16: note: declared here`

 `1011 |  unsigned int major = major(buf->st_rdev);`

   `|        ^~~~~`

`mksquashfs.c:1012:24: error: called object ‘minor’ is not a function or function pointer`

 `1012 |  unsigned int minor = minor(buf->st_rdev);`

   `|            ^~~~~`

`mksquashfs.c:1012:16: note: declared here`

 `1012 |  unsigned int minor = minor(buf->st_rdev);

解决方法：

修改: osdrv/tools/pc/squashfs4.3/Makefile

SQUASHFS    := squashfs4.3

改为:

SQUASHFS    := squashfs4.4

这里就是脚本补丁和readme中有差异的地方，为了解决这个错误，我们使用了squashfs4.4而不是squashfs4.3

经过以上两个修改，在ubuntu20.04上就可以完成了SDK的整包编译了。
