Documentation for suricata windows compile: [https://redmine.openinfosecfoundation.org/attachments/download/1175/SuricataWinInstallationGuide\_v1.4.3.pdf](https://redmine.openinfosecfoundation.org/attachments/download/1175/SuricataWinInstallationGuide_v1.4.3.pdf)

I have installed all the dependencies as mentioned in the documentation. Cloned the files.

To install libpcap, I followed the below steps:

1. Installed the winpcap installer: [WinPcap · Download](http://www.winpcap.org/install/default.htm)
2. Downloaded the Development pack as mentioned in the document: [WinPcap · Developer Resources](http://www.winpcap.org/devel.htm)
3. Copied all the headers and include files from development pack to the location mentioned in the documentation.

When I run the below command, I get the error: “ **configure: error: pcap.h not found** ”:

./configure --enable-luajit --enable-pie --enable-geoip --disable-gccmarch-native --with-libnss-libraries=/usr/lib --with-libnss-includes=/usr/include/nss/ --with-libnspr-libraries=/usr/lib --with-libnspr-includes=/usr/include/nspr
