Re: AC_CHECK_LIB doesn't find existing, linkable libraries

[Harry Mangalam]

Hi All,

salient points: 
Linux xxx.xxx.uci.edu 2.6.8.1-4-amd64-k8-smp #1 SMP Fri Jan 14 
11:33:56 UTC 2005 x86_64 GNU/Linux


config.log pointed me to a number of erroneous conditions which I've 
now corrected.  However, I'm still experiencing the same problem. 

That is, that a library that is found by ldconfig:
529 $ ldconfig -v |head
ldconfig: Path `/lib64' given more than once
ldconfig: Path `/usr/lib64' given more than once
/usr/local/lib:
        libnco_c++-2.9.9.so -> libnco_c++.so
        libnco-2.9.9.so -> libnco.so
        libdap++.so.1 -> libdap++.so.1.0
        libnc-dods.so.1 -> libnc-dods.so.1.0      <------ this is it

and which has the right symbols defined:

530 $ nm /usr/local/lib/libnc-dods.so.1 |grep nc_open
0000000000031540 T lnc_open
0000000000020830 T nc_open

but it cannot be grokked by the configure script which is set up as 
follows:
configure.in:    AC_CHECK_LIB([nc-dods],[nc_open],,enable_dods=no)


config.log reports:
configure:24221: checking for nc_open in -lnc-dods
configure:24251: gcc -o conftest -g -O2 -I/usr/local/include  
-L/usr/local/lib  conftest.c -ldap++ -lnc-dods -ldap++  -
/usr/bin/ld: cannot find -lnc-dods
collect2: ld returned 1 exit status

I'm afraid I'm flummoxed with this - any other hints?

Harry
