I also encountered this problem, can you get the answer？

[vnart]

Yes, I build the mongo-c-driver first then build nginx with the mongo-c-drive lib

[latticekun]

thanks，I will try it...

[johnbinwang]

Could you please explain your method in detail? I am also encountered this
problem.

use make or scons to build the mongo-c-drive lib ( refer to their website for further instruction). Then copy the lib to the right location.

Modify config for nginx-gridfs to:
NGX_ADDON_SRCS="$NGX_ADDON_SRCS $ngx_addon_dir/ngx_http_gridfs_module.c "
NGX_ADDON_DEPS="$NGX_ADDON_DEPS $ngx_addon_dir/mongo-c-driver/src/*.h"

CFLAGS="$CFLAGS --std=c99 -I src -I /usr/local/include -L /usr/local/lib -lmongoc "

Then build nginx with --add-module=/root/july2012/gridfs/ --with-ld-opt=-lmongoc

Should give you no error at all. However, the current version of nginx-grifs does not work well with replica set when the primary went offline. I had to make some change to the nginx-grifs source code to make it force reconnect the connection to detect the primary has change.

One more thing, have to use nginx restart for nginx-grifs to work other. If use reload it will cause problem and nginx just quit.

[latticekun]

it was done by your way! it works well! thank you very much! @vnart

[johnbinwang]

Thank you vnart, it works! The images fetched by nginx-grifs can be cached
now.
