Hi, I just checked out the python bindings for broccoli and tried building it against Bro 1.3.2 using the suggested "python setup.py install". I am using python 2.4.3 and gcc 4.1.2 on CentOS 5 Unfortunately the build just results in a few screens of compilation errors and warnings. Looking at the Makefile, I decided to try regenerating the swing bindings and running setup.pu again. This cut down the number of errors to only a single screenful. Here's what I'm getting: [sychan@panopticon python]$ python setup.py install running install running build running build\_py creating build creating build/lib.linux-i686-2.4 copying broccoli.py -\> build/lib.linux-i686-2.4 running build\_ext building '\_broccoli\_intern' extension creating build/temp.linux-i686-2.4 gcc -pthread -fno-strict-aliasing -DNDEBUG -O2 -g -pipe -Wall -Wp,-D\_FORTIFY\_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m32 -march=i386 -mtune=generic -fasynchronous-unwind-tables -D\_GNU\_SOURCE -fPIC -fPIC -I/usr/include/python2.4 -c broccoli\_intern\_wrap.c -o build/temp.linux-i686-2.4/broccoli\_intern\_wrap.o broccoli\_intern\_wrap.c:2504: warning: useless storage class specifier in empty declaration broccoli\_intern\_wrap.c: In function ‘valToPyObj’: broccoli\_intern\_wrap.c:2595: warning: pointer targets in passing argument 1 of ‘PyString\_FromStringAndSize’ differ in signedness broccoli\_intern\_wrap.c: In function ‘pyObjToVal’: broccoli\_intern\_wrap.c:2681: warning: pointer targets in assignment differ in signedness broccoli\_intern\_wrap.c: At top level: broccoli\_intern\_wrap.c:2762: error: expected declaration specifiers or ‘...’ before ‘BroEvMeta’ broccoli\_intern\_wrap.c: In function ‘event\_callback’: broccoli\_intern\_wrap.c:2767: error: ‘meta’ undeclared (first use in this function) broccoli\_intern\_wrap.c:2767: error: (Each undeclared identifier is reported only once broccoli\_intern\_wrap.c:2767: error: for each function it appears in.) broccoli\_intern\_wrap.c: In function ‘\_wrap\_bro\_event\_add\_val’: broccoli\_intern\_wrap.c:4716: warning: assignment discards qualifiers from pointer target type broccoli\_intern\_wrap.c: In function ‘\_wrap\_bro\_event\_set\_val’: broccoli\_intern\_wrap.c:4786: warning: assignment discards qualifiers from pointer target type broccoli\_intern\_wrap.c: In function ‘\_wrap\_bro\_event\_registry\_add\_compact’: broccoli\_intern\_wrap.c:4988: warning: assignment from incompatible pointer type broccoli\_intern\_wrap.c: In function ‘\_wrap\_bro\_record\_add\_val’: broccoli\_intern\_wrap.c:5849: warning: assignment discards qualifiers from pointer target type broccoli\_intern\_wrap.c: In function ‘\_wrap\_bro\_record\_set\_nth\_val’: broccoli\_intern\_wrap.c:6004: warning: assignment discards qualifiers from pointer target type broccoli\_intern\_wrap.c: In function ‘\_wrap\_bro\_record\_set\_named\_val’: broccoli\_intern\_wrap.c:6075: warning: assignment discards qualifiers from pointer target type error: command 'gcc' failed with exit status 1 [sychan@panopticon python]$ The first error "broccoli\_intern\_wrap.c:2762: error: expected declaration specifiers or ‘...’ before ‘BroEvMeta’" references this: // C-level event handler for events. We register all events with this callback, // passing the target Python function in via data. void event\_callback(BroConn \*bc, void \*data, BroEvMeta \*meta) { ... I don't see any declaration for the BroEvMeta type anywhere. There's a reference to this type in [http://svn.icir.org/bro/trunk/bro/aux/broccoli/test/broping.c](http://svn.icir.org/bro/trunk/bro/aux/broccoli/test/broping.c) in the bro\_pong\_compact() declaration: static void bro\_pong\_compact(BroConn \*conn, void \*data, BroEvMeta \*meta) However signature in my version of the broping is: static void bro\_pong\_compact(BroConn \*conn, void \*data, int num\_args, BroEvArg \*args) I'm guessing that things have changed since the 1.3.2 release and that the python bindings are against the current code base. Is that true? Do I need to download the latest bro source tree via subversion to use the pythong bindings? Steve ---

Yes, that's the problem here. There was an API change in Broccoli that in turn required the Python bindings to be adapted, which is why you're seeing these mismatches. If you don't want to upgrade Broccoli, you could check out an older revision of the Python bindings from my branch. The relevant change was in revision 5937 so if you, say, checkout revision 5936 it should work (and there haven't been any other changes since this to the bindings). Robin ---
