BUILDING ----------------------------------------------------------------------- In order to compile this software you should install development versions of Openssl BerkeleyDB flex bison PCRE to simplify building and fully enable the software. Type the following to build the software: $ tar zxf cfengine-3.0.0.tar.gz $ cd cfengine-3.0.0 $ ./configure && make If you only wish to test this software, you do not need to install it with "make install", nor do you need to run it with root privileges. You may run it as a regular user. TROUBLESHOOTING ----------------------------------------------------------------------- Problems linking? Try getting the latest cfengine version directly from svn. You only need to install the library host$ cd /workdir host$ svn checkout https://svn.iu.hio.no/projects/cfengine-3/trunk host$ cd trunk; ./configure;make host$ cd src; install -c .libs/libcfengine.a /usr/local/lib/libcfengine.a Some reports indicate that there is trouble compiling cfengine with recent versions 4.x of gcc. No problems are reported with gcc 3.x. EXAMPLES ----------------------------------------------------------------------- Some basic documentation is provided in the tests/units directory. Basic Installation ================== Cfengine depends on two packages. You should install up to date versions of these first. Berkeley Database obtainable from http://www.sleepycat.com OpenSSL obtainable from http://www.openssl.org Perl Compatible Regular Expressions Some operating systems with package managers will already contain packages for these libraries. If you use MacOS X you need to download and install a copy of BerkeleyDB, as well as a copy of the OpenSSL header files. The following are generic installation instructions. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, a file `config.cache' that saves the results of its tests to speed up reconfiguring, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.in' is used to create `configure' by a program called `autoconf'. You only need `configure.in' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. If you're using `csh' on an old version of System V, you might need to type `sh ./configure' instead to prevent `csh' from trying to execute `configure' itself. Running `configure' takes awhile. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package. 4. Type `make install' to install the programs and any data files and documentation. 5. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. OpenSSL Problem ===================== If you see error messages of the follwing type when upgrading OpenSSL: dso_dlfcn.c: undefined reference to `dlsym' /usr/local/ssl/lib/libcrypto.a(dso_dlfcn.o)(.text+0x31d):dso_dlfcn.c: undefined reference to `dlerror' /usr/local/ssl/lib/libcrypto.a(dso_dlfcn.o)(.text+0x3bf): In function `dlfcn_bind_var': dso_dlfcn.c: undefined reference to `dlsym' /usr/local/ssl/lib/libcrypto.a(dso_dlfcn.o)(.text+0x43b):dso_dlfcn.c: undefined reference to `dlerror' /usr/local/ssl/lib/libcrypto.a(dso_dlfcn.o)(.text+0x4a7): In function `dlfcn_unload': dso_dlfcn.c: undefined reference to `dlclose' /usr/local/ssl/lib/libcrypto.a(dso_dlfcn.o)(.text+0x563): In function `dlfcn_load': dso_dlfcn.c: undefined reference to `dlopen' /usr/local/ssl/lib/libcrypto.a(dso_dlfcn.o)(.text+0x5c9):dso_dlfcn.c: undefined reference to `dlclose' /usr/local/ssl/lib/libcrypto.a(dso_dlfcn.o)(.text+0x5fe):dso_dlfcn.c: undefined reference to `dlerror' collect2: ld returned 1 exit status make[2]: *** [cfagent] Error 1 Then you should make sure that you rebuilt *with* shared libraries and without static libcrypto.a libraries. Rename or remove /usr/local/ssl/lib/libcrypto.a and recompile. The libdl functions are apparently only available from shared libraries.
