Re: Buiding net-snmp perl in cygwin - Please anyone help me


Hi,

comments below.

Currently I uninstalled activeperl and I am having cygwin perl alone and
correspondingly I changed the Path variable to D:\cygwin\bin.

Herewith I am attcahing the output of "perl Makefile.PL", "make"

$ make

So this is the full error message. Alright, at first figure out where the missing symbols are defined, e.g.:

$ find /usr/local/lib -name "*.a" | xargs grep _SetIpNetEntry

Maybe in one of the snmp libraries, ie. libnetsnmpagent.a

than try to change the link order from:
-lnetsnmpagent -lnetsnmpmibs -lnetsnmphelpers -lnetsnmp
to:
-lnetsnmpmibs -lnetsnmpagent -lnetsnmphelpers -lnetsnmp

Issue the command manually in the directory where the object files are
and see if it works:
$ gcc -shared -o agent.dll \
   -Wl,--out-implib=libagent.dll.a \
   -Wl,--export-all-symbols \
   -Wl,--enable-auto-import \
   -Wl,--stack,8388608 \
   -s -L/usr/local/lib agent.o \
   usr/lib/perl5/5.8/cygwin/CORE/libperl.dll.a \
   -L/usr/local/lib -lnetsnmpmibs \
   -lnetsnmpagent -lnetsnmphelpers -lnetsnmp

If so, try to figure out what to change in Makefile.PL to reorder the
link command.

If this all fails, the submit a bug report to the address which should
be included in the README file.
