# OK, this is a pain.
|
|
#
|
|
# When building on NetBSD, with a libpcap installed from pkgsrc,
|
|
# a -Wl,-rpath,/usr/pkg/lib option is added to the options when
|
|
# linking tcpdump. This puts /usr/pkg/lib into the run-time path.
|
|
#
|
|
# However, by default, CMake adds a rule to the install CMake script
|
|
# a CMake command (using an undocumented subcommand of file()) that
|
|
# strips /usr/pkg/lib *out* of the run-time path; the message in the
|
|
# output for the "install" target is
|
|
#
|
|
# -- Set runtime path of "{target-directory}/tcpdump" to ""
|
|
#
|
|
# I am not certain what the rationale is for doing this, but a
|
|
# *consequence* of this is that, when you run the installed tcpdump,
|
|
# it fails to find libpcap.so:
|
|
#
|
|
# $ {target-directory}/tcpdump -h
|
|
# {target-directory}/tcpdump: Shared object "libpcap.so.0" not found
|
|
#
|
|
# It also appears to be the case that, on Ubuntu 22.04, FreeBSD 12,
|
|
# DragonFly BSD 5.8, OpenBSD 6.6, and Solaris 11.4,
|
|
#
|
|
# On Ubuntu and Solaris, even if you have a libpcap in /usr/local, you
|
|
# have to provide not only -I/usr/local/include and -L/usr/local/lib,
|
|
# you also must provide -Wl,-rpath,/usr/local/lib in order to have
|
|
# the run-time linker look in /usr/local/lib for libpcap. If it's not
|
|
# specified, then, if the shared library major version number of the
|
|
# libpcap in /usr/lib is the same as the shared major version number
|
|
# of the libpcap in /usr/local/lib, the run-time linker will find the
|
|
# libpcap in /usr/lib; if the versions are different, the run-time
|
|
# linker will fail to find the libpcap in /usr/lib, so the program will
|
|
# fail to run.
|
|
#
|
|
# We suppress this by setting CMAKE_INSTALL_RPATH_USE_LINK_PATH to TRUE;
|
|
# as the documentation for that variable says:
|
|
#
|
|
# Add paths to linker search and installed rpath.
|
|
#
|
|
# CMAKE_INSTALL_RPATH_USE_LINK_PATH is a boolean that if set to True
|
|
# will append to the runtime search path (rpath) of installed
|
|
# binaries any directories outside the project that are in the linker
|
|
# search path or contain linked library files. The directories are
|
|
# appended after the value of the INSTALL_RPATH target property.
|
|
#
|
|
# If, for whatever reason, directories in which we search for external
|
|
# libraries, other than the standard system library directories, are
|
|
# added to the executable's rpath in the build process, we most
|
|
# defintely want them in the installed image's rpath if they are
|
|
# necessary in order to find the libraries at run time.

|
|
# OK, this is a royal pain.
|
|
#
|
|
# CMake will try to determine the sizes of some data types, including
|
|
# void *, early in the process of configuration; apparently, it's done
|
|
# as part of processing the project() command.
|
|
#
|
|
# At least as of CMake 2.8.6, it does so by checking the size of
|
|
# "void *" in C, setting CMAKE_C_SIZEOF_DATA_PTR based on that,
|
|
# setting CMAKE_SIZEOF_VOID_P to that, and then checking the size
|
|
# of "void *" in C++, setting CMAKE_CXX_SIZEOF_DATA_PTR based on
|
|
# that, and then setting CMAKE_SIZEOF_VOID_P to *that*.
|
|
#
|
|
# The compile tests include whatever C flags may have been provided
|
|
# to CMake in the CFLAGS and CXXFLAGS environment variables.
|
|
#
|
|
# If you set an architecture flag such as -m32 or -m64 in CFLAGS
|
|
# but *not* in CXXFLAGS, the size for C++ will win, and hilarity
|
|
# will ensue.
|
|
#
|
|
# Or if, at least on Solaris, you have a newer version of GCC
|
|
# installed, but *not* a newer version of G++, and you have Oracle
|
|
# Studio installed, it will find GCC, which will default to building
|
|
# 64-bit, and Oracle Studio's C++ compiler, which will default to
|
|
# building 32-bit, the size for C++ will win, and, again, hilarity
|
|
# will ensue.
