1.4 compilation and Installation
$ Make # compile
# Make install # Run with root. After installation, the executable file is in/usr/local/vim72/bim /.
1.5 install it in the system
Now vim7.2 is installed, but when vi, vim, or vimdiff is run, the RedHat Linux9 comes with v1.6, this is because the installation PATH/usr/local/vim72/bin of vim7.2 is not in the path environment variable of the system. Now you only need to create a
the Linux kernel image to the flash memory, and execute it in the next process. In addition to the ability to store and start Linux imagesSome boot monitors can also perform system detection and hardware initialization to a certain extent. In an Embedded Target Board, these boot monitors typically cover the first and second phases of bootLoader function.

Cachegrind:
Cachegrind collects cpu statistics when the application is running by simulating the Level 1, 3 cache of the cpu, and prints detailed data and summary information.1. The following are some abbreviations of cpu statistics:I cache reads (Ir, which equals the number of instructions executed), I1 cache read misses (I1mr) and LL cache instruction read misses (ILmr ).D cache reads (Dr, which equals the number of memory reads), D1 cache read misses (D1mr), and LL cache data read misses (DLm

This function is frequently used in compilation principles and other courses. To implement this function, it is simple and difficult. The key is to check whether the data structure is used. What structure should I use? By the way, we often use the stack structure. In fact, in the existing syntax analyzer,

Note that the location of the three permissions does not change, and if there is no permission, a minus sign [-] is present.

Of these, 0~31 and 127 (total 33) are control characters or communication-specific characters, and the remainder are display characters.For example: char c = ' A ';' A ' represents a number 65 because the value of a in the ASCII-encoded table is 65, and so on:' B ' represents the 97, ' a ' represents' X ' stands for 88, ' 5 ' for 53,' = ' stands for 61, ' | ' Rep 124,The ' space '

the small end, before sending, we need to use the system-provided byte-order conversion function htonl () to convert it into the value of big-endian storage, as shown in Figure 2 below:
The Berkeley BSD Socket API defines a set of conversion functions for converting 16 and 32bit integers between the network order and the native byte order:
Htonl,htons is used for the conversion of the sequence to the network sequence; The Ntohl,ntohs is used to convert the network sequence to the native order.
