2014-09-09build: Don't overwrite CC variableTobias Klauser1-1/+1
Don't reset the variable CC in the Makefile, but set it to gcc by default (can be overriden when e.g. compiling with `make CC=clang'). This way we can also have non-verbose compiles with compilers other than gcc. Furthermore make sure that the CC variable is also respected for LD. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2014-09-08build: Detect compiler (gcc or clang) and filter out compiler flagsTobias Klauser1-0/+12
Create a make variable $(COMPILER) which is set to either `gcc' or `clang' depending on the compiler used. Use this variable to filter out command line options not supported by clang (for now only -fno-delete-null-pointer-checks). Compiler detection snippet extracted from the Linux kernel Makefile.

2014-08-15build: Add build flag to enable sparse checking of C source filesTobias Klauser1-0/+3
Similar to the 'make C=1' for the Linux kernel, wire up the sparse command for our build system in a similar fashion. Use 'make C=1 [tool]' to check the source files using sparse. Of course, the sparse tool needs to be installed and available in your $PATH for this to work. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>

2014-04-22conf: Use configuration file path from Makefile instead of hardcoded pathsTobias Klauser1-1/+1
Currently, the path to the configuration files is hardcoded to $PREFIX/etc/netsniff-ng. If we want to keep the configuration files outside of prefix (e.g. during development), we need to pass the complete path as specified in $ETCDIRE (and $ETCDIR respectively, which could e.g. be overriden on the command line during build install) as a preprocessor define. This way, we can e.g. install the configuration files to /etc while installing the binaries in /usr/local with: $ make PREFIX=/usr/local ETCDIR=/etc $ make PREFIX=/usr/local ETCDIR=/etc install Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2014-04-12build: fixed PREFIX usageChristian Wiese1-4/+4
This change fixes the use of PREFIX by not hard wiring /usr into the path. Besides that if no PREFIX is provided by the user, it is set to /usr/local now which is considered to be the right location for most LSB conforming distros if the user is compiling from sources to not interfere with the package management for binary packages which are build using /usr as prefix in most of the cases. current behavior without setting PREFIX will most likely interfere with most distro package managers when building from source: ------------------------------------------------------------------------ $ sudo make uninstall RM /usr/sbin/netsniff-ng RM /usr/share/man/man8/netsniff-ng.8.gz RM /usr/sbin/trafgen RM /usr/share/man/man8/trafgen.8.gz RM /usr/sbin/astraceroute RM /usr/share/man/man8/astraceroute.8.gz RM /usr/sbin/ifpps RM /usr/share/man/man8/ifpps.8.gz RM /usr/sbin/bpfc RM /usr/share/man/man8/bpfc.8.gz RM /usr/sbin/curvetun RM /usr/share/man/man8/curvetun.8.gz ------------------------------------------------------------------------ current behavior when setting PREFIX=/usr/local looks kind of weird because of the hard wired /usr: ------------------------------------------------------------------------ $ sudo make PREFIX=/usr/local uninstall RM /usr/local/usr/sbin/netsniff-ng RM /usr/local/usr/share/man/man8/netsniff-ng.8.gz RM /usr/local/usr/sbin/trafgen RM /usr/local/usr/share/man/man8/trafgen.8.gz RM /usr/local/usr/sbin/astraceroute RM /usr/local/usr/share/man/man8/astraceroute.8.gz RM /usr/local/usr/sbin/ifpps RM /usr/local/usr/share/man/man8/ifpps.8.gz RM /usr/local/usr/sbin/bpfc RM /usr/local/usr/share/man/man8/bpfc.8.gz RM /usr/local/usr/sbin/curvetun RM /usr/local/usr/share/man/man8/curvetun.8.gz ------------------------------------------------------------------------ using the proposed fix without setting PREFIX: ------------------------------------------------------------------------ $ sudo make uninstall RM /usr/local/sbin/netsniff-ng RM /usr/local/share/man/man8/netsniff-ng.8.gz RM /usr/local/sbin/trafgen RM /usr/local/share/man/man8/trafgen.8.gz RM /usr/local/sbin/astraceroute RM /usr/local/share/man/man8/astraceroute.8.gz RM /usr/local/sbin/ifpps RM /usr/local/share/man/man8/ifpps.8.gz RM /usr/local/sbin/bpfc RM /usr/local/share/man/man8/bpfc.8.gz RM /usr/local/sbin/curvetun RM /usr/local/share/man/man8/curvetun.8.gz ------------------------------------------------------------------------ Signed-off-by: Christian Wiese <chris@opensde.org> Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2014-04-10build: add DESTDIR supportChristian Wiese1-0/+4
This change implements support for specifying an alternative installation destination directory by setting DESTDIR when calling 'make install'. Example: make DESTDIR=/alternative-rootfs install It is particularly useful when cross-compiling and installing in a dedicated directory where for example the rootfs or a build sandbox for the target architecture is mounted. By using DESTDIR you can avoid to mess with PREFIX to include the alternative installation directory!

Add a Makefile target to build and upload a snapshot of netsniff-ng to the Coverity scanner. The variables COV_EMAIL and COV_PASSWD need to be set accordingly: make coverity COV_EMAIL=tklauser@distanz.ch COV_PASSWD=... Currently the sub-make which is part of the cov-built call issues warnings about undefined variables from the template. This can be ignored, the build works just fine.

2013-07-30build: reduce Extra contents to bare minimumDaniel Borkmann1-2/+0
Improve the build system, so that configuration files are installed per tool basis. Also, introduce post_install targets, so that config files can be altered in some way, e.g. done by trafgen. Moreover, move custom targets from Extra to tool-specific Makefiles. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-07-30build: Don't uninstall configuration filesTobias Klauser1-1/+0
Several of the tools install/uninstall files from $NCONF_FILES, however if we call the uninstall target for a specific tool (e.g. `make astraceroute_uninstall') but other tools depending on one or more of the config files are still installed, the file is still removed unconditionally. As it would require quite some logic in the Makefile in order to detect installed tools and their dependencies, we just don't uninstall the configuration files anymore.

2013-07-29build: use VERSION_SHORT instead of VERSION_STRINGDaniel Borkmann1-2/+3
We have recently changed VERSION_STRING to append CONFIG_RC at the end of the string. Thus, for the build system, change it to VERSION_SHORT where needed, e.g. in release targets where the "+" appendix is not wished. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>

2013-07-24build: add "+" version appendix automatically during buildDaniel Borkmann1-3/+3
For each build that has no tag name (thus for all commits except releases), we add a "+" version appendix to indicate that it is further than the rc tag itself, like in the kernel. Do this during configure automatically. This is useful in case someone wants to package a relase, so that the full version name indicates that. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-07-24build: split build system into smaller manageable piecesDaniel Borkmann1-225/+25
Split the build system into smaller manageable pieces, grouped by context. In that sense, we can keep the most important information within the Makefile itself, and group out misc bits and pieces that we just include into it. E.g. 'Cmds' contains all defined commands that we call from other locations, 'Template' contains the generic build template for all tools, 'Extra' has pieces that need special treatment for the tools to build and 'Misc' contains help and release code. This makes it more manageable on the long run. While at it, I also simplified some code and removed all Wflags expect "-Wall" as we want to convert into "-Wall -Wextra -W" anyway.

2013-07-15configure: silent complaint if not built on git repositoryDaniel Borkmann1-1/+1
This silences a complaint if the toolkit is not built within a Git repository: ... [*] Checking libnet ... [YES] fatal: Not a git repository (or any of the parent directories): .git [*] Generating config.h ... [*] Looks good! All tools will be built! This is not problematic as the build can be done without any problems. It will just have an empty Git id in --version output. So simply silence this complaint and move on.

2013-07-09configure: fix multiple issues in build configurationDaniel Borkmann1-10/+1
This patch is a bundle of multiple fixes. 1) Fix compilation of astraceroute when HAVE_LIBPCAP=1: astraceroute doesn't need libpcap, so add an additional guard/define to bpf.h and bpf_comp.c and netsniff-ng.c. Also since we generate a config.h file, we do not need to have this additional compile flag anymore. 2) Fix tstamping.{h,c} to use the configure script instead of the Makefile. For doing this, also fix the object inclusion in netsniff-ng/Makefile. Last but not least, rename __WITH_... into HAVE_... as this is more clean. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-07-09configure: let configure script generate config.h fileDaniel Borkmann1-0/+1
While we're at it, also let configure script generate the config.h file. The generation of it is currently quite static, but that could change in future. While at it, we also generate a GITVERSION define, that we will use for ``--version'' output of the individual tools for being able to provide better support since we can see what concrete commit people are using when building from Git repo.

2013-07-08configure: netsniff-ng: libpcap is not a hard dependencyDaniel Borkmann1-1/+7
netsniff-ng uses libpcap only for high-level filter compiling. Thus, let netsniff-ng not "hard-depend" on libpcap, but rather disable filter compiling in case the user does not want to install libpcap. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>

2013-07-08configure, Makefile: Conditionally build toolsTobias Klauser1-0/+1
Instead of halting out the entire build build if one dependency is not available, only exclude the tools that link against it from building. The configure script will now print a list of all tools that will be built -- and in case some libaries are not available -- that will not be built. Also add checks for libcli and libnet which mausezahn depends on. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-07-05Makefile, INSTALL: Simplify clean/uninstall Makefile targetsTobias Klauser1-20/+23
Streamline the Makfile targets by separating the clean targets (which only affect the build tree) from the uninstall targets (affecting files installed in the system). Do this by renaming the 'distclean' target to 'uninstall' and removing unnecessary aliases. The 'distclean' target serves now as a way to remove build files and Config. The 'mrproper' will bring the source into a pristine state as checked out from git. Summary of the new/changed targets: clean: remove all build related files (but not Config) distclean: 'make clean' + remove Config mrproper: remove all files not in git repository uninstall: remove all files installed by us from the system, but not affecting the build environment. %_uninstall: tool specific uninstall The following targets were removed: mostlyclean, realclean and clobber. Also the target names in the INSTALL file are adjusted. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-07-05configure, Makefile: Fail in Makefile if Config is not completeTobias Klauser1-1/+4

2013-06-28configure: Check for presence of pkg-config and ccache binariesTobias Klauser1-1/+1
Check whether pkg-config and ccache are in the PATH. A missing pkg-config will cause the configure script to abort with an error. The presence of ccache is written to Config and used by the Makefile to conditionally make use of it. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-06-24configure: Add configure script used to detect NaClTobias Klauser1-0/+3
In order to use an installation of NaCl provided by the distro or by previous manual installation, provide a configure script which checks for nacl's presence. Also check of libnl-genl headers. More checks of the other libraries depended on by netsniff-ng as well as checks for necessary kernel headers should be added here too. The configure script is preliminary and has not yet extensively been tested on multiple systems. The concept was inspired by the configure script of trinity and iproute2.
