Hello,
Sorry for bother you again with lame question, but I'm stuck on linking with
libspf2.
I got these errors:
g++ -L/usr/local/lib -o"CstpSpf" ./src/SpfResolver.o ./src/cstp_spf.o
-lspf2
./src/SpfResolver.o: In function `SpfResolver':
/home/dunmer/workspace/CstpSpf/Debug/../src/SpfResolver.cpp:14: undefined
reference to `SPF_dns_resolv_new(SPF_dns_server_struct*, char const*, int)'
/home/dunmer/workspace/CstpSpf/Debug/../src/SpfResolver.cpp:16: undefined
reference to `SPF_dns_cache_new(SPF_dns_server_struct*, char const*, int,
int)'
/home/dunmer/workspace/CstpSpf/Debug/../src/SpfResolver.cpp:17: undefined
reference to `SPF_dns_set_conserve_cache(SPF_dns_server_struct*, int)
With this simple code:
this->spfResolvServer = SPF_dns_resolv_new(NULL, "spfResolv", DEBUG);
this->spfCacheServer = SPF_dns_cache_new(this->spfResolvServer, "spfCache",
DEBUG, CACHE_SIZE);
SPF_dns_set_conserve_cache(this->spfCacheServer, CACHE_CONSERVE);
DEBUG, CACHE_CONSERVE and CACHE_SIZE are my constants.
I have built and installed libspf and its located in /usr/local/lib. I tried
to move it to the /usr/lib with no success. I'm using Eclipse for C/C++ and
I have set libspf2 in libraries.
What am I doing wrong? Google didn't help. And what is with libspf2.org?
I will really appreciate your help. Thank you very much!
Not sure whats going on, libspf2 has those symbols on my box and i can
link a simple program (attached) with:
gcc -o fish -I/usr/local/include -L/usr/local/lib -lspf2 foo.c
It could be that your -o"CstpSpf" is being miss interpreted and needs a
space?
P.S. you can use 'ldd' to see which libraries a lib or binary is linked
against and 'nm' to see which symbols a library or program exports or
defines.
