Unable to figure out a mysterious link failure in Freeswitch

Question

While trying to link a Freeswitch endpoint (mod_h323) in VS2012, I get the following error.

------ Build started: Project: mod_h323, Configuration: Debug x64 ------ LINK : fatal error LNK1104: cannot open file 'c:/opensource/freeswitch-1.2.22/libs/openssl-1.0.1c/lib/VC/libeay32MDd.lib'

I am simply unable to find out where this link instruction is specified. I would like to point to a different library file, but where is this link instruction hidden? I am unable to get past this error.

Edit: What are the different ways of specifying link libraries in VC++?

Answer 1

At first you should check if the library is specified at the linker command line. In the project Property Page navigate to

- Configuration Properties
  - Linker
     -Command Line

If you find the lib here, you have passed it in the project properties. If not the library request can be added by a #pragma comment directives. To find the object (or library) file with that directive you have to dump all directives with the command

for %o in (*.obj *.lib) do dumpbin /directives %o

When you fond the object file, you need to find the corresponding pragma in the source file.
