Linux 的網路連線設定

Actually, additionally to Maximes answer, you could change the GRUB commandline in your box until the new version is propagated.

Just go to /etc/default/grub and set the appropriate line to GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0" You have to change the /etc/network/interfacesto reflect the correct names (eth0...)

$ edit /etc/network/interfaces

# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)
# The loopback interface
# automatically added when upgrading
auto lo
iface lo inet loopback

# The first network card - this entry was created during the Debian installation
# (network, broadcast and gateway are optional)
# automatically added when upgrading
auto eth0
iface eth0 inet static
        address 211.21.247.10
        netmask 255.255.255.248
        network 211.23.247.8
        broadcast 211.23.247.15
        gateway 211.23.247.9

$ /etc/init.d/networking stop         # 停掉網路裝置
$ ifconfig                            # 你會發現空空如也
$ /etc/init.d/networking start        # 啟動網路裝置
$ ifconfig                            # 網路裝置回覆 
$ route -n                            # 網路裝置回覆

错误“Error found when loading /root/.profile”解决

source:
http://blog.sina.com.cn/s/blog_68b1e07d0102vcqd.html

在刚修改完root权限自动登录后，发现开机出现以下提示：
Error found when loading /root/.profile
stdin:is not a tty
…………
解决方法：在终端中用命令gedit /root/.profile，打开文件后找到“mesg n”，
将其更改为“tty -s && mesg n”。

sudo do-release-upgrade 更新ubuntu

down vote

I tried using :

sudo do-release-upgrade

and then use :

sudo apt-get update

after that you will be able to install any packages.

If this did not worked for you try to change the network conf in apt.conf

libmp4v2 新project在make修改注意

1. 沒有 configure
2.需要由 configure.ac 來產生 configure
#autoconf configure.ac
error: possibly undefined macro: AC_PROG_LIBTOOL
=> 需要安裝 : libtool
=> apt-get install libtool (failed)
=> 下載libtoolXXX.tar.gz 來安裝(我是找最新版本)
source:
https://ftp.gnu.org/gnu/libtool/
https://www.gnu.org/software/libtool/

>> ./configure
>> make clean && make
>> make install (相關檔案拷貝至/usr/share/local)

==
- make 過程會缺一些tool，閉缺逐一安裝
- makeinfo:
source: 要安裝 texinfo
http://ftp.ntu.edu.tw/gnu/texinfo/

- help2man
source:
http://ftp.ntu.edu.tw/gnu/texinfo/

- aclocal-1.15
source: 找相關版本安裝
https://ftp.gnu.org/gnu/automake/

[question]mv: cannot stat ‘t-cs.gmo’: No such file or directory
>> autoreconf --install.

[question]configure 已產生，執行也沒問題，但執行make會出現~
help2man: can't get `--help' info from ./mp4art
Try `--no-discard-stderr' if option outputs to stderr

解決方法:
/libmp4v2xxxx/doc/GNUmakefile.mk
line 64 =>
HELP2MAN.flags = -m "$(PROJECT_name) Utilities" -N --no-discard-stderr

ARM移植MP4V2

source2:
http://blog.csdn.net/pb09013037/article/details/39498029

下載mp4v2:
https://code.google.com/archive/p/mp4v2/downloads

GNUmakefile說明:
http://www.cc.ntut.edu.tw/~yccheng/oop2005f/GNUMakeManual.pdf

1、./configure --prefix=/home/linux/workspace/mp4v2-build --host=arm CC=arm-linux-gcc CXX=arm-linux-g++

2、make

3、make install

4、在这个目录下/home/linux/workspace/mp4v2-build，可以查看到编译生成的文件

./configure --prefix=/home/jeff/workspace/mp4v2-2.0.0_mod_g711/ --host=arm-unknown-linux-uclibcgnueabi CC=/usr/src/arm-linux-3.3/toolchain_gnueabi-4.4.0_ARMv5TE/usr/bin/arm-unknown-linux-uclibcgnueabi-gcc CXX=/usr/src/arm-linux-3.3/toolchain_gnueabi-4.4.0_ARMv5TE/usr/bin/arm-unknown-linux-uclibcgnueabi-g++

make clean

執行完configure後，會產生GNUmakefile，ㄎ

之後需要先make clean

再 make 誠能成功

結果 ==>

./.libs/libmp4v2.a

make: Nothing to be done for `all' 解决方法

1.这句提示是说明你已经编译好了，而且没有对代码进行任何改动。

若想重新编译，可以先删除以前编译产生的目标文件：
make clean
然后再
make

2.出现这种情况解决方法：

a.make clean 清除安装时留下的文件

b.在运行一下ldconfig
