ProxySQL编译报错

问题描述

同一台机器以往都能正常编译ProxySQL，有一天编译突然报错：

1）报错场景一

bash 复制代码

2）报错场景二

bash 复制代码

3）报错场景三

bash 复制代码

make[4]: Leaving directory '/proxysql/deps/curl/curl-8.4.0/src'
make[3]: Leaving directory '/proxysql/deps/curl/curl-8.4.0/src'
make[3]: Entering directory '/proxysql/deps/curl/curl-8.4.0'

make[2]: Leaving directory '/proxysql/deps/curl/curl-8.4.0'
make[1]: Leaving directory '/proxysql/deps'

刚开始有很多猜测：

1）同时存在多个编译器版本，如GCC 4.8、GCC 7、GCC 11等导致编译混乱；

2）安装了不该存在的依赖等等；

但经过证实都非上述原因。

解决方案

1）查看是否配置了 CXXFLAGS 和 CFLAGS

bash 复制代码

echo $CXXFLAGS
echo $CFLAGS

若输出如下：

则需删除对应配置：

bash 复制代码

# 删除配置
unset CXXFLAGS
unset CFLAGS

# 验证是否删除
echo $CXXFLAGS
echo $CFLAGS

2）重新编译

bash 复制代码

make cleanall
make -j`nproc`

编译成功：

3）原因分析

ProxySQL 的 deps/Makefile 可能对 re2 有特殊的编译逻辑。当你设置全局CXXFLAGS="-fPIC -02" 时，会覆盖或干扰 ProxySQL 内置的编译选项。
