make: *** [/opt/buildroot-2012.08/output/toolchain/gcc-4.5.4-initial/.compiled] 错误 2
如果编译交叉编译器是出现这些问题可能就是pc上的编译器和交叉编译器的gcc版本不同引起的，这时候看一下PC的版本：
[fulinux@ubuntu buildroot-2012.08]$ gcc --version
gcc (Ubuntu/Linaro 4.8.1-10ubuntu8) 4.8.1
Copyright (C) 2013 Free Software Foundation, Inc.
This is free software; see the source for copying conditions. There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
这是4.8.1的版本，而交叉编译器的gcc版本是4.5.4版本。
在交叉编译器的.config文件中作如下类似的修改：
[fulinux@ubuntu buildroot-2012.08]$ vim .config
#

How to analyze the execution plan of MySQL queryApr 29, 2025 pm 04:12 PMUse the EXPLAIN command to analyze the execution plan of MySQL queries. 1. The EXPLAIN command displays the execution plan of the query to help find performance bottlenecks. 2. The execution plan includes fields such as id, select_type, table, type, possible_keys, key, key_len, ref, rows and Extra. 3.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
