After searching, almost no such software is available. Microsoft's vs2010 does not support this very practical function.
In fact, the Project Properties of VC under vs2010, C/C ++'s command line contains the command line, followed by cl.exe, followed by the price file name, when there is a link, you can manually compile link.exe at the previous price.
However, the GUI method is troublesome. In fact, you can obtain these parameters and all functions from vcxproj. Vcxproj is an XML file.
You only need to extract some key information from the XML file and output it to the MAKEFILE file.
The required library has XML
Makefile for nmake specifications are required.
In this way, you can write such software. Currently, I am writing, and wait for the release to be completed.
There is also a small foreign http://www.codeproject.com/Articles/28908/Tool-for-Converting-VC-2005-Project-to-Linux-Makef software online, it is estimated that it is good, but I am prompted that no dll can be compiled, back to find, then, a function for converting vs2010 to GNU makefile and nmake mkefile is released.
