First download the latest GCC (http://ftp.gnu.org/gnu/gcc/), I used the gcc-6.1.0.tar.gz, uploaded to Linux via FTP, decompression:
TAR-ZVXF gcc-6.1.0.tar.gz--directory=/usr/local/
cd/usr/local/gcc-6.1.0
Then use VI to open the./contrib/download_prerequisites file to see which dependencies you need for the currently downloaded GCC. When you open it, you see the following:
From this, we also need to download gmp-4.3.2.tar.bz2, isl-0.15.tar.bz2,

In fact, this approach is wrong, the "microphone" "mute" option is not to control the microphone audible, but to control the speakers and headphones are feedback microphone sound. So we recommend that when using the mi

The current mode of mechanical disk operation, mainly reflected in the disk reading and writing to find the track of the process, the disk caching function for reading and writing speed is very important. Disk search process is a mechanical way, so that its random speed is significantly lower than the sequential reading and writing, generally ordinary disk IO can reach 40--60MB per second, slightly better words are about 100MB per second, in the case of multiple processes or multithreading concu
In the Audio Switcher window, select the Enable built-in audio switch filter and sound delay time (milliseconds) option, and then calculate the time value based on the time difference between the steps and enter into the box, negative for sound playback, positive value for the sound in advance. Finally, click the "Apply" button. So the sound will be played ahead or late.

Pygame method of playing music, pygame playing music
This article describes how to play music in pygame. Share it with you for your reference. The details are as follows:
Method 1:
Import pygamefilename = '/home/A.mp3' pygame. mixer. music. load (filename) pygame. mixer. music. play (loops = 0, start = 0.0)
Method 2:
Import pygamefilename = '/home/pengtao/Music/B .mp3' pygame.
I tried to implement this function and found a lot of information, which was not powerful. Finally, I found that what Microsoft gave was usable, in general, the mixer API is used to open the mixer device, obtain audio line information, and then set attributes. After this is done, it can be used in programs you write, such as players.
There are several functions in total:
Through these nine APIs, we can con
