SDSOC rivision 编译文件缺少opencv头文件

这两天早SDSOC上使用rivision stack。导入例程说缺少头文件opencv.

其实这个问题是查看SDSOC中licence manage中发现HOSTID为00000000。

所以首先需要重新设置eth0.

As you can see in the following command, my system is having a network adapter called ens33.

Note: This is just the case of VMware environment, it may vary depends on the hardware but the steps to get back ethX will be the same.

$ ip a1: lo: <loopback,up,lower_up> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00    inet 127.0.0.1/8 scope host lo       valid_lft forever preferred_lft forever    inet6 ::1/128 scope host       valid_lft forever preferred_lft forever2: </loopback,up,lower_up>ens33: <broadcast,multicast,up,lower_up> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000    link/ether 00:0c:29:05:a3:e2 brd ff:ff:ff:ff:ff:ff    </broadcast,multicast,up,lower_up>inet 192.168.12.12/24 brd 192.168.12.255 scope global dynamic ens33       valid_lft 1683sec preferred_lft 1683sec    inet6 fe80::20c:29ff:fe05:a3e2/64 scope link       valid_lft forever preferred_lft forever

From the dmesg command, you can see that the device got renamed during the system boot.

$ dmesg | grep -i eth[    3.050064] e1000 0000:02:01.0 eth0: (PCI:66MHz:32-bit) 00:0c:29:05:a3:e2[    3.050074] e1000 0000:02:01.0 eth0: Intel(R) PRO/1000 Network Connection[    3.057410] e1000 0000:02:01.0 ens33: renamed from eth0

To get an ethX back, edit the grub file.

$ sudo nano /etc/default/grub

Look for “GRUB_CMDLINE_LINUX”  and add the following”net.ifnames=0 biosdevname=0“.

From:

GRUB_CMDLINE_LINUX=""

To:

GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"

Generate a new grub file using the following command.

$ sudo grub-mkconfig -o /boot/grub/grub.cfgGenerating grub configuration file ...Warning: Setting GRUB_TIMEOUT to a non-zero value when GRUB_HIDDEN_TIMEOUT is set is no longer supported.Found linux image: /boot/vmlinuz-4.4.0-15-genericFound initrd image: /boot/initrd.img-4.4.0-15-genericFound memtest86+ image: /memtest86+.elfFound memtest86+ image: /memtest86+.bindone

Edit the interface file and change the network device name so that you will have a DHCP or static IP address for ethX.

READ: Install and configure DHCP server on CentOS 7 / Ubuntu 14.04

DHCP:

If your infrastructure has a DHCP server and you want to leverage that, then:

$ sudo nano /etc/network/interfaces

Update below lines in /etc/network/interfaces files so that the network card can get an IP address from DHCP server.

FROM:

auto ens33iface ens33 inet dhcp

TO:

auto eth0iface eth0 inet dhcp

Static:

If your infrastructure does not have a DHCP server, then you will need to configure a static IP address for all network interfaces on your Ubuntu machine.

$ sudo nano /etc/network/interfaces

From:

auto ens33iface ens33 inet static           address 192.168.12.12           netmask 255.255.255.0           dns-nameservers 192.168.12.2           gateway 192.168.12.2

To:

auto eth0iface eth0 inet static           address 192.168.12.12           netmask 255.255.255.0           dns-nameservers 192.168.12.2           gateway 192.168.12.2

Reboot your system.

$ sudo reboot

After the system reboot, just check whether you have an ethX back.

$ ip a1: lo: <loopback,up,lower_up> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00    inet 127.0.0.1/8 scope host lo       valid_lft forever preferred_lft forever    inet6 ::1/128 scope host       valid_lft forever preferred_lft forever2: </loopback,up,lower_up>eth0: <broadcast,multicast,up,lower_up> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000    link/ether 00:0c:29:05:a3:e2 brd ff:ff:ff:ff:ff:ff    </broadcast,multicast,up,lower_up>inet 192.168.12.12/24 brd 192.168.12.255 scope global eth0       valid_lft forever preferred_lft forever    inet6 fe80::20c:29ff:fe05:a3e2/64 scope link       valid_lft forever preferred_lft forever

That’s All, drop your thoughts in the comments section.

需要注意的是每次使用revision的时候需要添加 SYSY ROOT。当然也可以将其添加到系统环境变量里面去
