compiler-errors - fatal error : apr_time.h: No such file or directory

Question

#include <apr_time.h>

导致以下编译错误:

fatal error: apr_time.h: No such file or directory

当我做

locate apr_time.h

它输出

/usr/include/apr-1.0/apr_time.h

因此，我相信我已经使用 sudo apt-get install libapr1-dev正确安装了该库。如果我做

pkg-config --cflags --libs apr

我懂了

Package apr was not found in the pkg-config search path.
Perhaps you should add the directory containing `apr.pc'
to the PKG_CONFIG_PATH environment variable
No package 'apr' found

如何确保找到 apr_time.h？

Answer 1

尝试

#include <apr-1.0/apr_time.h>

代替。
