Compiling on Windows 7 has issues

[Sha]

I am on Windows 7, using tdm64-gcc-5.1.0-2 and SmartGit make.

This is what I see, when I compile Lemon:


$ make

I am aware that it is not finding the correct library (in this case shlwapi.lib) and am trying to get the appropriate SDK installed before I can proceed.

I was able to get it to compile when I changed line 8 of the Makefile to:

      LDFLAGS += -lws2_32 -lshlwapi

No issues so far....

I added -lShlwapi to Makefile,It should be ok now, I forget merge Windows version's Makefile.

The fix worked! Thanks...
