I have customized a new nginx add on module,and the module use an  
external  
lib ( mytest.so).  
The method i called in mytest.so is kimtest method.  
How can i configure the ./configure file and Makefile to prevent the  
error "  
undefined reference to `kimtest’ "

Here is the configure file…

auto/configure --with-debug --with-ld-opt=“-L/usr/local/lib64”  
–add-module=./src/my\_nginx\_module

while configuring … everything seems ok, no error occurs.  
but while making … " undefined reference to `kimtest’ "

Something like

CORE\_LIBS=“$CORE\_LIBS -lmytest”

in your module config file should do the trick.

Hi Maxim D.,

```
i solved the problem as you provided solution.
But i face another problem, that is while starting the nginx server,

```

still lack of the library at runtime.  
I should set the LIBRARY\_PATH in order to start the nginx correctly.  
(  
export LD\_LIBRARY\_PATH)  
Is there any suggestion or setting to set the install config ?

BRs,  
Kim
