clang编译mysql(Ubuntu10 64位)_MySQL
Ubuntu
bitsCN.com编译安装mysql(Ubuntu10 64位) http://www.cnblogs.com/2018/p/3482259.html 这个介绍了gcc形式编译安装mysql
那我们使用clang进行编译一下看看具体的效果
编译安装mysql(Ubuntu10 64位) 已经描述了mysql的编译安装情况,由于clang的性能比较高,现在实验一下mysql的clang编译
经试验,主要解决如下的问题即可
v ABI_CHECK
n 这个问题表现是配置完成后,编译时会出现ABI的报错,google了一下,由于官方没有直接clang的支持,因此可以忽略,网上有人这样用过
v Clang编译器的引入
n 或者在cmake的配置文件修改,或者使用环境变量进入,使用一个简单的形式如下,引入clang编译器即可
export CXX=clang++
export CC=clang
最初我看了一下clang++连接到的就是clang,因此我想当然的认为直接都设置为clang就行,不过编译会出错提示AES undefined reference operator delete(void*),具体看了一下原因,如下的地址
clang vs calng++

如上处理就可以了编译和安装了,具体的脚本如下:
if [ -d mysql-5.6.15 ]; then
echo "mysql代码已经存在了"
else
tar xzf mysql-5.6.15.tar.gz
fi
#cmake/abi_check.cmake ABI检查的问题,可以跳过
# LINE30 SET(RUN_ABI_CHECK 0)
cp -f abi_check.cmake mysql-5.6.15/cmake/abi_check.cmake
mkdir -p build
pushd build
if [ -f CMakeCache.txt ]; then
make clean
rm -f CMakeCache.txt
fi
#使用clang编译
export CXX=clang++
export CC=clang
#编译时看看是否启用了clang
cmake ../mysql-5.6.15 /

#end of cmake
if [ $? -ne 0 ];
then
echo -e "/e[1;41m cmake's config error! /e[0m"
exit 1
fi
make
if [ $? -ne 0 ];
then
echo -e "/e[1;41m cmake done! /e[0m"
exit 1
fi
popd
echo "The package is in build directory!"

Laravel is a PHP framework for easy building of web applications. It provides a range of powerful features including: Installation: Install the Laravel CLI globally with Composer and create applications in the project directory. Routing: Define the relationship between the URL and the handler in routes/web.php. View: Create a view in resources/views to render the application's interface. Database Integration: Provides out-of-the-box integration with databases such as MySQL and uses migration to create and modify tables. Model and Controller: The model represents the database entity and the controller processes HTTP requests.

MySQL and phpMyAdmin are powerful database management tools. 1) MySQL is used to create databases and tables, and to execute DML and SQL queries. 2) phpMyAdmin provides an intuitive interface for database management, table structure management, data operations and user permission management.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

I encountered a tricky problem when developing a small application: the need to quickly integrate a lightweight database operation library. After trying multiple libraries, I found that they either have too much functionality or are not very compatible. Eventually, I found minii/db, a simplified version based on Yii2 that solved my problem perfectly.

Article summary: This article provides detailed step-by-step instructions to guide readers on how to easily install the Laravel framework. Laravel is a powerful PHP framework that speeds up the development process of web applications. This tutorial covers the installation process from system requirements to configuring databases and setting up routing. By following these steps, readers can quickly and efficiently lay a solid foundation for their Laravel project.

When developing an e-commerce website using Thelia, I encountered a tricky problem: MySQL mode is not set properly, causing some features to not function properly. After some exploration, I found a module called TheliaMySQLModesChecker, which is able to automatically fix the MySQL pattern required by Thelia, completely solving my troubles.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.
