Please, attach config.log and wiretap/config.log.
Created attachment 125839 [details, diff] wireshark-0.99.6-ldflag-lm.patch You will get the config.log and wiretap/config.log in a second. (I blowed away my /var/tmp/..../wireshark dir so i need to recompile)
Created attachment 125841 [details] config.log as requested
Created attachment 125842 [details] wiretap/config.log
After applying the previously attatched wireshark-0.99.6-ldflag-lm.patch the linking works. "Forgetting" -lm is a common mistake since glibc works without it. Other libc's are not as forgiving.
Created attachment 125849 [details, diff] wireshark-0.99.6-lm.patch Eh. Your clarification helped me to recall the problem. But why do you fix compilation of the programs which compiles with libwireshark, while the problem is in libwireshark? Does this ^^ patch works for you? Thank you for report, BTW :)
Also, may be the correct solution will be use @LIBM@ and add AC_CHECK_LIBM into wiretap/configure.in which is part of libtool distribution (libtool.m4).
(In reply to comment #9) > Also, may be the correct solution will be use @LIBM@ and add AC_CHECK_LIBM into > wiretap/configure.in which is part of libtool distribution (libtool.m4). > Sounds like the proper way to handle this. Should be reported upstream too. btw. The patch you posted works too. (my patch was shooting at anything that was moving...)
wireshark-0.99.6-r1 is commited with the fixes for this problem too. Please, report if I did anything wrong, as I do not have system with ulibc to test the fix. Again, thank you for report... fixed. :)
