Summary0011319: VS2010 generator failed to create rule file
DescriptionThe following code:

set(errdbg_GENERATED ${CMAKE_CURRENT_BINARY_DIR}/errdbg/generated.txt)

ADD_CUSTOM_COMMAND(
 OUTPUT ${errdbg_GENERATED}
 COMMAND ${CMAKE_COMMAND} -E copy ${PROJECT_SOURCE_DIR}/myfile.txt ${CMAKE_CURRENT_BINARY_DIR}/errdbg/generated.txt
 DEPENDS ${PROJECT_SOURCE_DIR}/myfile.txt)

 ADD_CUSTOM_TARGET(${PROJECT_NAME} DEPENDS ${errdbg_GENERATED})

fails to generate errdbg/generated.txt.rule. Which means that VS 2010 is building this project again and again.

The following command fixes this (before set):

execute_process(COMMAND mkdir ${CMAKE_CURRENT_BINARY_DIR}/errdbg)
TagsNo tags attached.

 There is a fix for this already in next, please try a nightly CMake binary.

 Do you mean cmake-2.8.2.20101015-gcde67-win32-x86.exe? I've tried it. It still fails to create the rule file if remove 'mkdir' command from the 'kernel/common/cmakelists.txt'.

 Doesn't work on 2.8.3-rc3 either. I still get:

========== Build: 1 succeeded, 0 failed, 1 up-to-date, 0 skipped ==========

every time I start build.

 Reattached the file (removed mkdir command to make it reproducible right from the package). Unfortunatelly, bug still reproducible with cmake 2.8.3.

Please, let me know if you failed to reproduce. We need this to be fixed since it stops our VS 2010 migration.

 I'm seeing something like this too on CMake 2.8.4 / MSVC2010. Create the following CMakeLists.txt file:

#############
project(test NONE)
cmake_minimum_required(VERSION 2.8)

set(name ${CMAKE_CURRENT_BINARY_DIR}/a/b.txt)

add_custom_command(
  OUTPUT ${name}
  COMMAND ${CMAKE_COMMAND} -E touch ${name}
  COMMENT "running command"
)

add_custom_target(one ALL DEPENDS ${name})
##################


Then run "cmake ." once followed by "msbuild test.sln" multiple times. Each run displays "running command" even though the file "a\b.txt" is created on the first build. Creating an empty "a\b.txt.rule" file (which didn't exist) myself fixes it.

If, however, the "name" does not contain a subdirectory:

  set(name ${CMAKE_CURRENT_BINARY_DIR}/b.txt)

cmake *will* create b.txt.rule file, and the "running command" correctly displays only on the first build.

The problem does not occur, however, when targeting autotools.
