c - how to symlink a shared object file (lib) -

how symlink lib file loaded shared library?

root@root:/usr/lib# ls -l /usr/lib/ | grep libpcap -rw-r--r-- 1 root root 351636 2010-01-04 20:15 libpcap.a lrwxrwxrwx 1 root root 14 2011-08-18 01:56 libpcap.so -> libpcap.so.0.8 lrwxrwxrwx 1 root root 16 2011-08-18 01:56 libpcap.so.0.8 -> libpcap.so.1.0.0 lrwxrwxrwx 1 root root 25 2013-02-19 10:01 libpcap.so.1 -> /usr/lib/libpcap.so.1.0.0 -rw-r--r-- 1 root root 204128 2010-01-04 20:15 libpcap.so.1.0.0 root@root:/usr/lib# start-wfw checking wlan0 homecoming 1 root@root:/usr/lib# /tmp/wfw: error while loading shared libraries: libpcap.so.1: cannot open shared object file: no such file or directory root@root:/usr/lib# stop-wfw stopping () wfw: no process found

os: backtrack 5 r1, 64 | arch: x86_64

initially, echo ld_library_path, returns blank line.

after creating symlink, ran ldconfig, , retried executable, no avail.

if set ld_library_path /usr/lib, elf error.

thanks in advance.

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
