*SQL.so and the other libraries are plugins and their location is
specified in ulogd.conf so I can put them in /usr/lib/ulogd or
elsewhere. It's a function in ulogd.c which load these plugins:
/* plugin loader to dlopen() a plugins */

ulogd_log(ULOGD_ERROR, load_plugins: %s - %s\n, file, dlerror());

My only other guess would be that configure cannot find the mysql and pgsql paths, you could try to set them also (but it is strange that it works with glibc). I tried the new ulogd.mk but unfortunately results are almost the same for both MYSQL and PGSQL plugins [File not found]. The difference is that for pgsql I get File not found for BASE.so and PGSQL.so and for mysql File not found is only for MYSQL.so. I don't know exactly how the two database applets interact with MySQL and Postgress. You could also look at the config.log for errors after you build the sources. config.log looks the same for uClibc and glibc. I'll try to ask the author of ulogd, maybe he has an idea.

Re: [leaf-user] Bering uClibc - ulogd: load_plugins: /usr/lib/ulogd/ulog_*.so - File not found
Hi all, I've downloaded ulogd-0.98 from CVS, applied the patch and compiled for uClibc, made ulogd.lrp and reboot with the new package. Ulogd complains about finding plugins specified in /etc/ulogd.conf [/usr/lib/ulogd/ulogd_*.so File not found] but all needed plugins are fine, owned by root in /usr/lib/ulogd/ ] The same ulogd package built for glibc works fine :( If anyone has any idea ... Thanks in advance, lwd. Laurentiu, Did you follow the instructions in ulogd.txt and used ulogd.mk? (ulogd.mk changed a week ago, so maybe you must download it again) I know it works, just tried it myself. There is also a complete ulogd.lrp package compiled for uClibc in CVS.

Hi Eric,
Yes, I followed the instructions and used the new version of ulogd.mk;
the trouble is at line 448 in ulogd.c:
if (!dlopen(file, RTLD_NOW)) {
ulogd_log(ULOGD_ERROR, load_plugins: %s - %s\n,
file, dlerror());
..
I changed it to print file content and it's OK /usr/lib/ulogd/
...and so on. So, IMHO the problem may be dlopen() of uClibc ?...
Any suggestions?
I did all this because I need ulogd_PGSQL plugin and I like to do
things by myself. That's why I believe Bering is GREAT!
Thanks,
lwd
