Question

我收到的错误可以在下面看到，错误来自我创建的静态库（libredis.a）：

/root/projects/lib/libredis.a(redisHandler.o): In function redisHandler.cpp:(.text+0x1394): undefined reference to `std::ctype<char>::_M_widen_init() const'
collect2: ld returned 1 exit status

我100％肯定这个静态lib和我的项目是用相同的g ++版本构建的（g ++ 46）我在makefile中使用了-std = c ++ 0x -static-libstdc ++ -static-libgcc选项。

以下是来自项目的问题的gcc输出，对不起详细信息：

当我构建静态库

时还有gcc输出

[root@ ~/projects/test]# gmake clean all install
mkdir -p /root/projects/lib     && cd /root/projects/lib;     rm -f libredis.a;                   cd -

mkdir -p /root/projects/lib     && cp -pf libredis.a /root/projects/lib
mkdir -p /root/projects/include && cp -pf include/redisHandler.hpp  /root/projects/include

我找不到任何可能发生此错误的原因，如果你们有一些想法我会非常感激。

Ps：请大家不要关闭其他主题对此问题没有帮助的问题。

即使我很小心静态库和项目正在使用不同的库，因为评论者建议我。至少我可以说明我是如何解决它的：

[root@ ~/projects/INSEPTRA_RELENG_12_8_chunk]#  find / -name "libstdc++.a"
/usr/lib/libstdc++.a
/usr/local/lib/gcc46/libstdc++.a
/usr/local/lib/gcc47/libstdc++.a
/usr/lib32/libstdc++.a
/root/projects/lib/libstdc++.a
[root@ ~/projects/INSEPTRA_RELENG_12_8_chunk]# cp /usr/lib/libstdc++.a /usr/lib/libstdc++.a_bak
[root@ ~/projects/INSEPTRA_RELENG_12_8_chunk]# cp /usr/local/lib/gcc46/libstdc++.a /usr/lib/libstdc++.a
[root@ ~/projects/INSEPTRA_RELENG_12_8_chunk]# cp /usr/local/lib/gcc46/libstdc++.a /usr/lib32/libstdc++.a
[root@ ~/projects/INSEPTRA_RELENG_12_8_chunk]# cp /usr/local/lib/gcc46/libstdc++.a /root/projects/lib/libstdc++.a
[root@ ~/projects/INSEPTRA_RELENG_12_8_chunk]# gmake

链接器错误：来自静态lib的`std :: ctype <char> :: _ M_widen_init（）的未定义引用。即使使用相同的gcc版本</char>
