Compiling libpcap -- header issues

Hey guys, I'm trying to compile libpcap from source and I'm encountering some issues. Here's the error log from make:

gcc -fpic -I.  -I/usr/include/libnl3 -I/usr/include/dbus-1.0 -I/usr/lib/dbus-1.0/include -I/usr/lib/modules/3.17.1-1-ARCH/build/include/net -I/usr/lib/modules/3.17.1-1-ARCH/build/include -DHAVE_CONFIG_H  -D_U_="__attribute__((unused))" -g -O2 -c ./pcap-bt-monitor-linux.c

compilation terminated.
Makefile:84: recipe for target 'pcap-bt-monitor-linux.o' failed
make: *** [pcap-bt-monitor-linux.o] Error 1

Now, I did change the makefile by adding  /usr/lib/modules/3.17.1-1-ARCH/build/include and /usr/lib/modules/3.17.1-1-ARCH/build/include/net to my include path,
because it was necessary to get it to compile at an earlier step. But now, as you can see from the first error, a file in libpcap wants the header linux/types.h, but I believe
it is referring to the "types.h" in /usr/include/linux/types.h, and not the types.h in /usr/lib/modules/3.17.1-1-ARCH/build/include/linux/types.h, which is different.

How can I resolve this? I have to include the path /usr/lib/modules/3.17.1-1-ARCH/build/include because libpcap needed it for some bluetooth headers or something.
But how can I tell gcc to look at the other linux/types.h instead? Or would I have to move some files around?

EDIT: It seems like the actual issue here is that /usr/include/sys/types.h is included. Somehow, the __USE_MISC macro is being defined, causing sys/select.h and sys/types.h to be included, thus including fd_set twice.....But I've grepped the libpcap source and I can't find __USE_MISC anywhere....

Re: Compiling libpcap -- header issues

Hi lu6cifer,

can you be more precise?

do you mean you downloaded the PKGBUILD for core/libpcap and  you are trying to build it using makepg or you are trying to compile the source code downloaded  from upstream?

What headers? What error message did you receive?

Re: Compiling libpcap -- header issues

One of the headers was <bluetooth/mgmt.h>, which was only in /usr/lib/modules/3.17.1-1-ARCH/build/include and not /usr/include/bluetooth

I was trying to compile the source downloaded from upstream.

Re: Compiling libpcap -- header issues

Well, the problem is that you cannot directly include /usr/lib/modules/3.17.1-1-ARCH/build/include to your include path, because doing this will lead to conflicting declarations. Moreover, it seems that unfortunately the file mmgt.h present in the aforementioned directory is not compatible with libpcap. However you can find a compatible version of the header  here.

One way to resolve your problem is then to create a custom include directory in which you will copy the missing header (that is basically what is done inside the PKGBUILD). Let's say, for example, that ${source_dir} is the directory containing the libpcap sources then you have to execute the following commands:

#creating custom include directory
mkdir -p ${source_dir}/include/bluetooth

#downloading the missing header into it
curl https://projects.archlinux.org/svntogit/packages.git/plain/trunk/mgmt.h?h=packages/libpcap -o ${source_dir}/include/bluetooth/mgmt.h

#Adding the custom include directory to the include path
export CFLAGS="$CFLAGS -I${source_dir}/include"

#Finally run the configure script
./configure --prefix=/usr
