Summary
A multi-threaded program created by a developer sometimes generates an error value or produces other strange behaviors. Odd behavior occurs when a multi-threaded program does not use a synchronous serialization thread to access key code. What does synchronous serialization threads mean by accessing key code? This article explains synchronization, Java synchronization mechanism, and two problems that occur when developers do not
latest Vim 7.1 source code. Suppose we put the code in ~ /Install/directory. The file name is vim-7.1.tar.bz2.
[Download vimgdb Patch]
Next, we need to download the vimgdb patch. The download page is:
Http://sourceforge.net/project/showfiles.php? Group_id = 111038 package_id = 120238
Here, select the vim 7.1 patch and save it ~ /Install/vimgdb71-1.12.tar.gz.
[Patching]
Run the following command to decompress the source code file and install patches:
