我下载并尝试安装“wfconvert”包此链接.但我遇到了一些错误。
这是我所做的：
- 复制根目录“/”中的 wfconvert 文件夹

我不知道该怎么办！
这是我的 cmath 文件列表：

请帮我。
答案1
我怀疑是开发工具安装损坏或类似问题。我要做的第一件事是重新安装构建包
sudo apt-get purge build-essential
sudo apt-get install build-essential
如果问题仍然存在，请回复
只是好奇：你是如何安装 GCC 4.8 的？我有 13.04，它有 4.7.3，所以如果操作不正确，这可能是一个问题！
答案2
编译时 libm 是否也会自动链接？
libm 用于编译器 g++，并自动链接。如果您使用 gcc 作为编译器，则需要手动链接 math.h
我在这里找到了有关不同编译器的链接：
https://stackoverflow.com/questions/1033898/why-do-you-have-to-link-the-math-library-in-c
顺便说一下 -http://boost.org
您也可以编译并包含 boost-libraries。
答案3
使用 gcc 它看起来像这样：
gcc example.c -o example -lm
为了更精确地进行编译（在发生故障时进行调试输出），您可以执行以下操作：
gcc -ggdb -Wall example.c -o example -lm
这里 lm 是与 gcc 的数学库的链接（在 example.c 的开头有 #include math.h）。
