问题现象：
../depcomp: line 512: exec: g++: not found
make[2]: *** [my_new.o] Error 127
make[2]: Leaving directory `/usr/local/src/mysql-5.0.41/mysys'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/usr/local/src/mysql-5.0.41'
make: *** [all] Error 2
 
解决办法：
安装gcc-c++
 
安装完成之后再次编译make
可能会出现如下错误:
../include/my_global.h:909: error: redeclaration of C++ built-in type `bool'
make[2]: *** [my_new.o] Error 1
make[2]: Leaving directory `/home/tools/mysql-5.0.22/mysys'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/tools/mysql-5.0.22'
make: *** [all] Error 2
是因为gcc-c++是在configure之后安装的，此时只需重新configure后再编译make即可。
