Hi All,

I am getting error below error for own written module ds\_http\_module.

nginx: [emerg] dlopen() “/usr/local/nginx/modules/ds\_http\_module.so”  
failed (/usr/local/nginx/modules/ds\_http\_module.so: undefined symbol:  
ds\_http\_module

Please let me know what could be the reason of this error.

Regards,
