hisi SDK在ubuntu20.04上面编译可能出现的问题以及解决方法：

1. hi_gzip编译错误

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."`

解决方法：
cp hi_gzip_Makefile /mnt/ext/aec/hi3559/Hi3559V200_MobileCam_SDK_V1.0.1.5/osdrv/tools/pc/hi_gzip/Makefile

# for hi3516
cp hi_gzip_Makefile /mnt/ext/hi3516/Hi3516CV500R001C02SPC020/01.software/board/Hi3516CV500_SDK_V2.0.2.0/osdrv/tools/pc/hi_gzip/Makefile

2. eudev编译错误

解决方法：

cp eudev-3.2.7_Makefile /mnt/ext/aec/hi3559/Hi3559V200_MobileCam_SDK_V1.0.1.5/osdrv/tools/board/eudev-3.2.7/Makefile

# for hi3516
cp eudev-3.2.7_Makefile /mnt/ext/hi3516/Hi3516CV500R001C02SPC020/01.software/board/Hi3516CV500_SDK_V2.0.2.0/osdrv/tools/board/eudev-3.2.7/Makefile

# for hi3559v200 SDK2.0.1.0
cp eudev-3.2.9_Makefile /mnt/ext/hisi/smp_hi3559v200/Hi3559V200_SDK_V2.0.1.0/open_source/eudev/Makefile

3.squashfs编译错误

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);

解决方法：

cp squashfs4.3_Makefile /mnt/ext/aec/hi3559/Hi3559V200_MobileCam_SDK_V1.0.1.5_5.3G/osdrv/tools/pc/squashfs4.3/Makefile
cp squashfs4.4.tar.gz /mnt/ext/aec/hi3559/Hi3559V200_MobileCam_SDK_V1.0.1.5_5.3G/osdrv/tools/pc/squashfs4.3/.

# for hi3516
cp squashfs4.3_Makefile /mnt/ext/hi3516/Hi3516CV500R001C02SPC020/01.software/board/Hi3516CV500_SDK_V2.0.2.0/osdrv/tools/pc/squashfs4.3/Makefile
cp squashfs4.4.tar.gz /mnt/ext/hi3516/Hi3516CV500R001C02SPC020/01.software/board/Hi3516CV500_SDK_V2.0.2.0/osdrv/tools/pc/squashfs4.3/.


4.-Werror=format-truncation= 错误
/mnt/ext/aec/hi3559/Hi3559V200_MobileCam_SDK_V1.0.1.5_5.3G/reference/tools/upgrade_generate/src/hi_upgrade_generate_main.c:375:68: error: ‘%s’ directive output may be truncated writing up to 63 bytes into a region of size between 54 and 117 [-Werror=format-truncation=]

解决方法：
cp hi_upgrade_generate_main.c /mnt/ext/aec/hi3559/Hi3559V200_MobileCam_SDK_V1.0.1.5_5.3G/reference/tools/upgrade_generate/src/hi_upgrade_generate_main.c

cp init2bin_Makefile /mnt/ext/aec/hi3559/Hi3559V200_MobileCam_SDK_V1.0.1.5_5.3G/reference/dashcam/modules/param/ini2bin/Makefile
