我正在尝试将PCRE库编译为测试可执行文件。
文档指出，运行Make然后进行配置应生成该库。
在PCRE源目录中：
Make
./configure
gcc -o test test.c -L . -lpcre
但是，以下错误返回：
/usr/bin/ld: cannot find -pcre
collect2: error: ld returned 1 exit status
注意：我也尝试过标记
-libpcre。我能够在MacOS上成功运行它（分别编译，但相同的库源代码和相同的验证源代码）。目录内容：

链接时，请尝试-lpcre而不是-libpcre。 -l假定使用lib前缀并使用lib的名称，因此-lpcre查找libpcre
关于c - GCC链接器找不到库，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/42447163/
