@fengjianxinghun 这 可能是对 HR 招聘看的, 那我们自身应该如何去评价？

@vincent441 他好像是使用 sync 出了问题，然后推荐 gevent,eventlet 异步模式，我 sync 模式是完全 ok 的， 但是 gevent,eventlet 模式不行.

解决了 extern "C" 我删掉了 忘记加上去了， 所以没有导出来， 加上后 重新编译 函数也能导出来了。

还有很多这样的 ， 次数超过限制所有发不出来

@nifury @qbqbqbqb
@qbqbqbqb 我加了-fPIC 参数， 虽然能编译， 但是函数好像没有导出， 这个时候 应该怎么导出

@qbqbqbqb 我删除 extern "C" __declspec(dllexport) 这个了，但是出现了上面的错误， 你知道吗

@nifury 你知道这个错误吗？ 我吧 extern "C" __declspec(dllexport) 删掉了

@elfive 请教一下，win 本地 make 能 ok ， 但是在服务器就找不到一个文件， 这是没有指定路径还是啥？

@elfive gcc 都是最新的。 这不是源码吗？ 应该是官方的吧

但是错误好像还是这个

@elfive 我不是 c++开发，是 python 开发

@elfive 这是修改后的
__uctype __urngmin = _UniformRandomBitGenerator::min();
__uctype __urngmax = _UniformRandomBitGenerator::max();
assert( __urngmin < __urngmax);

报错信息变多了....

@elfive 好像还是不行， 弄了就出新的一堆错误

@elfive static_assert( __urngmin < __urngmax, "Uniform random bit generator must define min() < max()");

我删除 static_ 后 就是上面的报错

@elfive 方法 1 成功解决一部分，但是方法 2 好像不行还是报错了 出现了两个新的错误

@elfive 我是要 修改 /usr/include/c++/11/bits/uniform_int_dist 这些底层文件是吗？ 修改后 会对其他代码编译什么的受影响吗

@AoEiuV020CN 请教一下你是怎么发图片 的
