Summary0013116: Cmake Nmake generator generate empty /MACHINE:for first run under a project
DescriptionCmake Nmake generator generate empty /MACHINE: for first run under a folder that make the compilation failed, if delete the folder contents and run the same cmake command again, then everything works as expected and /MACHINE:x86 is properly generated in the makefiles.
Steps To Reproducet.c
#include <stdio.h>

/* main entry */
int
#if defined(_MSC_VER)
__cdecl
#endif
main(int argc, char *argv[]) {
  printf("Hello world!\n");
  return 0;
}


CMakeLists.txt
cmake_minimum_required(VERSION 2.8)

project(test)

add_executable(test t.c)

then bring up cmd prompt and run under the folder:
cmake -G "NMake Makefiles" .

would result error if you run nmake

delete all the generated temp files and run the above step again, everything worked.

I cannot reproduce this. I get /machine:X86 on the link line after the very first configuration.

What version of CMake are you testing?

version is cmake 2.8.7 platform is win7 x64 for 32 bit vc environment, OS language is eastern, msvc is 10.0 newest patch.

in CmakeCache.txt, the wrong line is:

//Flags used by the linker.
CMAKE_EXE_LINKER_FLAGS:STRING=' /STACK:10000000 /machine: '

//Flags used by the linker during debug builds.
CMAKE_EXE_LINKER_FLAGS_DEBUG:STRING=/debug /INCREMENTAL:YES

//Flags used by the linker during release minsize builds.
CMAKE_EXE_LINKER_FLAGS_MINSIZEREL:STRING=/INCREMENTAL:NO

in my test in order to reproduce it, I must close all cmd.exe instance and reopen one, if not all cmd.exe closed after successful cmake build for second time, then it would work as expected.

I have the same environment except the OS language is English:

>type ..\CMakeLists.txt
cmake_minimum_required(VERSION 2.8)
project(test)
add_executable(test t.c)

>type ..\t.c
#include <stdio.h>

/* main entry */
int
#if defined(_MSC_VER)
__cdecl
#endif
main(int argc, char *argv[]) {
  printf("Hello world!\n");
  return 0;
}

>cmake --version
cmake version 2.8.7

Oh，finally I reasoned out what caused the strange result, it's because I run the cmake .. -G"NMake Makefiles"
without setting vcvars.bat first, then I saw the cmake error message need to setup and run vcvars.bat, I just run it, now second time run cmake just works, but the flags in cmakecache.txt is obviously wrong.

so this may not be a bug, but an improvement that cmake can make to sugguest unsccessfull run exists and delete cache files, just like the suggestions make as to different compiler runs.
