Linux 自动工具配置脚本中存在版本错误

我试图从源代码交叉编译

libnetfilter_queue-1.0.2

，我的构建环境变量指向正确的交叉工具链和相关库路径

在

/configure

checking for LIBNFNETLINK... no
configure: error: Package requirements (libnfnetlink >= 0.0.41) were not met:

No package 'libnfnetlink' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables LIBNFNETLINK_CFLAGS
and LIBNFNETLINK_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

我的配置命令是：

CFLAGS="-I/home/user/openwrt/openwrt/staging_dir/target-powerpc_8540_uClibc-0.9.33.2/lib/ 
-I/home/user/openwrt/openwrt/staging_dir/target-powerpc_8540_uClibc-0.9.33.2/usr/lib/ -I/home/user/openwrt/openwrt/staging_dir/target-powerpc_8540_uClibc-0.9.33.2/include/ 
-I/home/user/openwrt/openwrt/staging_dir/target-powerpc_8540_uClibc-0.9.33.2/usr/include"  
LDFLAGS="-L/home/user/openwrt/openwrt/staging_dir/target-powerpc_8540_uClibc-0.9.33.2/lib/ 
-L/home/user/openwrt/openwrt/staging_dir/target-powerpc_8540_uClibc-0.9.33.2/usr/lib/" 
./configure --build=x86_64-unknown-linux-gnu --host=powerpc-openwrt-linux-uclibcspe  
--prefix=/home/user/openwrt/openwrt/staging_dir/target-powerpc_8540_uClibc-0.9.33.2

另外，我已经在传递给./configure的-I和-L路径之一中安装了libnfnetlink.so.0.2.0

尽管如此，我为什么会出错呢

编辑：一些额外的信息

您安装了

libnfnetlink

二进制文件，但要满足

/configure

对于

libnetfilter\u队列

您需要安装

libnfnetlink

开发库，因为

libnetfilter\u队列

在编译时需要它的头。这还将提供

pkg\u config

信息，以

/configure

正在寻找，例如，在：

/usr/lib/x86_64-linux-gnu/pkgconfig/libnfnetlink.pc

你没有说你的发行版是什么，但在debian衍生品上

sudo apt-get install libnfnetlink-dev

这将解决这个问题

库签入

/configure

脚本通常需要开发库

另外，我刚记得你是交叉编译的，所以

pkg\u config

---

将需要找到目标的开发库信息。

在

config.log

中查找错误，然后稍微查看LIBNFNETLINK检查的实际操作。您的pkg配置路径中是否也有相应的.pc文件？@MikeKinghan请参见编辑：嗨，实际上我也安装了头文件，由于您指出头是必需的，所以我在那个里检查了路径并在环境中设置了路径，现在它可以编译了。
