If you need Broccoli, go to aux/broccoli after the Bro build and configure and build it separately. Try --disable-posix-semaphores. If that doesn't help, feel free to email me. I'll throw out all of the semaphores stuff once I have time for Broccoli again, because it doesn't help instrumentation in enough situations to warrant the build headaches it's been causing.

Don't mind this one. This is most probably due to linking with "-ltermcap" when doing the long-long test. So once the termcap issue is solved, this should disappear too. Robin ---

Ah right! In the older version the termcap check didn't abort on error. Cheers, Christian. ---

The configure was tightened up in 1.1 to point to the termcap problem (and not give this misleading error) Cheers, jason ---

Hi Dominic -- do you have the devel RPM installed? The libtermcap.so is likely the crucial bit, as will be the header: christian@strangepork:/usr/lib \> rpm -ql libtermcap-devel /usr/include/termcap.h /usr/lib/libtermcap.a /usr/lib/libtermcap.so /usr/share/info/termcap.info.gz Regarding the other issue, please du as Jason + Vern suggest. Cheers, Christian. ---

Debian (for example), doesn't ship a termcap. Their equivalent is ncurses. Termcap is required by libedit, but I don't see any place in the build process that actually uses libedit. I've compiled (but not yet actually run) the tree without libedit (or libtermcap) successfully. Am I missing something? (working from bro-1.1 sources) ---

No worries, glad it gets a little further now. šŸ™‚ Your case suggests though that we should be testing for the header file first, because that would make it more immediately clear that it's the devel setup that's lacking. Cheers, Christian. ---

Hi Dominic, > Christian, > > I'm not sure which outputs you want. Is it just configure.log (which I've > attached) or do you need other things as well? I actually only meant what you get to see at the console, but the .log is even better. Thanks. This is what I was after: configure:7934: checking for ns\_msg configure:7981: result: yes configure:8007: checking for ns\_inittab/res\_mkquery with resolver 'none' configure:8128: result: no configure:8007: checking for ns\_inittab/res\_mkquery with resolver '-lresolv' configure:8128: result: no configure:8007: checking for ns\_inittab/res\_mkquery with resolver '/usr/lib/libresolv.a' configure:8128: result: no configure:8134: Nonblocking DNS disabled. Given this, you should not have seen the link error. I think the problem is that DNS\_Mgr.cc's DNS\_Mgr::AnswerAvailable() isn't correctly protected by #ifdef HAVE\_NB\_DNS. The attached diff might fix it but is untested. > I've dug around a bit and I think I've got as far as seeing that in > src/Makefile, dns\_srcs is null. Yes, this is in line with the above, since configure has determined that it can't build with nbdns support. Cheers, Christian.

I don't have more time to look into this, but I'm sure someone else will. I'm much more interested to find out how nbdns can be made to work on your system, so if you could find out whether there's really no resolver library that defines ns\_inittab/res\_mkquery, that'd help... Cheers, Christian. ---

My resolver library (-lresolv) contains the strings mkquery and ns\_initparse [dom@tility lib]$ strings /lib/libresolv.so.2 | grep mkquery \_\_res\_mkquery \_\_res\_nmkquery [dom@tility lib]$ strings /lib/libresolv.so.2 | grep parse ;; ns\_initparse: %s ;; ns\_parserr: %s However, configure fails to find ns\_initparse despite having -lresolv on the compile command. Indeed, trying it standalone confirms this. [dom@tility bind-9.3.2]$ cat test.c #include \ int main () {   ns\_initparse(0,0,0);   ;   return 0; } [dom@tility bind-9.3.2]$ gcc -o test test.c -lresolv /home/dom/tmp/ccm4khEq.o(.text+0x1a): In function `main': : undefined reference to `\_\_ns\_initparse' collect2: ld returned 1 exit status Googling didn't turn up an obvious place to get a resolver library that contains ns\_initparse so I'm a bit stumped.
