Compiling libpcap for QNX

Cross-compiling

It is possible to cross-compile libpcap from this source tree on a Linux host for a QNX 8.0 target as follows:

  1. Obtain a licence, download and install QNX Software Center.
  2. Using QNX Software Center, install a suitable version of QNX SDP (for example, 8.0.3 works) and note the SDP installation directory (for example, ~/qnx800). There is no need to install the Momentics IDE.
  3. Initialize environment variables and cross-compile libpcap for the required target. For example, for AArch64: 
    . ~/qnx800/qnxsdp-env.sh
./configure --host=aarch64-unknown-nto-qnx8.0.0
make
  4. Cross-compile the required software using libpcap.a and the headers from the libpcap source tree.

Native compiling

Depending on the QNX host, it may be possible to build libpcap natively. For example, this works on QNX SDP 8.0.3 QSTI build 245 after installing the usual dependencies (apk add flex bison). Note that at the time of this writing this works differently from cross-compiling: the native environment does not have the headers to enable netmap(4) support and does not have a library to enable remote capture support.
