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?
