Summary: execute_process() run from add_custom_command() via
cmake -P fails to capture output for VS2008
Description:
in my project I have a post-build custom command:
add_custom_command(TARGET dynamorio POST_BUILD
COMMAND ${CMAKE_COMMAND}
ARGS -D lib=${drout}
-D DUMPBIN_EXECUTABLE=${DUMPBIN_EXECUTABLE}
-P ${CMAKE_CURRENT_SOURCE_DIR}/CMake_checkdeps.cmake
VERBATIM)
where CMake_checkdeps.cmake is:
--------------------------------
execute_process(COMMAND
${DUMPBIN_EXECUTABLE} /dependents "${lib}"
RESULT_VARIABLE deps_result
ERROR_VARIABLE deps_error
OUTPUT_VARIABLE deps_out
)
if (deps_result OR deps_error)
message(FATAL_ERROR "*** ${DEPS_EXECUTABLE} failed: ***\n${deps_error}")
endif (deps_result OR deps_error)
string(REGEX MATCH "following dependencies:.*Summary" dlls "${deps_out}")
string(REGEX REPLACE "\r?\n" "" dlls "${dlls}")
string(REGEX REPLACE "following dependencies: *" "" dlls "${dlls}")
string(REGEX REPLACE " *Summary" "" dlls "${dlls}")
if (NOT dlls MATCHES "^ntdll.dll$")
message(FATAL_ERROR "*** Error: ${lib} depends on more than ntdll.dll:
${dlls}")
endif ()
----------------------------
This all works fine with VS2010. However, with VS2008, the output of
dumpbin.exe is not captured and is instead printed out to the console/shell.
The deps_error and deps_out variables are both empty.
If I run this custom_command at config time, it works fine. If I run the script
through cmake -P it works fine whether from cmd or a cygwin rxvrt shell:
% cmake.exe -D lib=C:/src/dr/git/build_x86_dbg/lib32/debug/dynamorio.dll -D
"DUMPBIN_EXECUTABLE=C:/Program Files (x86)/Microsoft Visual Studio
9.0/VC/bin/dumpbin.exe" -P C:/src/dr/git/src/core/CMake_checkdeps.cmake
But when VS2008 runs the command, it fails due to not capturing the output.
The line in the .vcproj file is:
<Tool
Name="VCPostBuildEventTool"
CommandLine="C:\PROGRA~2\CMAKE2~1.8\bin\cmake.exe -D
lib=C:/src/dr/git/build_x86_dbg/lib32/debug/dynamorio.dll -D
"DUMPBIN_EXECUTABLE=C:/Program Files (x86)/Microsoft Visual Studio
9.0/VC/bin/dumpbin.exe" -P
C:/src/dr/git/src/core/CMake_checkdeps.cmake
if errorlevel 1 goto
:VCReportError"/>
If I substitute "cl.exe /help" for "dumpbin.exe ..." the same problem is there:
the output is not captured.
