what is the problem in make file . how to link libssl with my app ?

you can download code from here https://rapidshare.com/files/458792519/test.rar (it includes code from liboauth )

To summarize the conversation in the comments on the OP, I downloaded the example code and ran nmake against it (makefile.nt). I did get linker errors but the missing symbols were from Win32 libs. I added user32.lib and gdi32.lib to the LIBS list in the makefile and it then linked cleanly (the build worked with VS2005, VS2008, and VS2010).

As the OP points out, it also linked cleanly when adding those two additional libraries. It is not clear to me how that would help resolve those symbols from libeay32.lib. So my suspicion is that the change to the make file resulted in a full rebuild and compile of all .obj files. The full clean build resulted in it working. So maybe (I'm just guessing) the .obj files were compiled incorrectly originally (compiler that didn't work well with the linker perhaps?) and the full rebuild made everything consistent.
