Debian 9: fatal error: 'curl/curl.h' file not found, even though libcurl4-openssl-dev is installed?

Question

基本上如标题所说：Debian 9：致命错误：'curl/curl.h' 找不到文件，即使安装了 libcurl4-openssl-dev？

headers 在 /usr/include/x86_64-linux-gnu/curl/ 中，我在 /usr/include/curl 和 /usr/local/include/curl 中都建立了符号链接。

我做过什么傻事吗？我错过了一步吗？

您可能需要在编译时指定包含目录。

要列出您的默认包含路径，您可以运行命令

# clang -xc -E -v -

这将列出搜索 header 的位置。例如

#include "..." search starts here:
#include <...> search starts here:
 /usr/lib/gcc/x86_64-linux-gnu/7/include
 /usr/local/include
 /usr/lib/gcc/x86_64-linux-gnu/7/include-fixed
 /usr/include/x86_64-linux-gnu
 /usr/include
End of search list.

漂亮的工具 pkg-config 可以帮助您找到 libcurl 所需的路径。

# pkg-config --cflags libcurl
-I/usr/include/x86_64-linux-gnu

从这里我们看到您的路径包含在内，但抱怨的编译器是 aarch64-linux-android-clang.

可能的答案

尝试运行

# aarch64-linux-android-clang -xc -E -v -

看看是否表明搜索的路径不包含有问题的 header。您可能还需要为 aarch64 获取 headers（和 libcurl）。

祝你好运！
