[CMake] command line too long when compiling CUDA code with WindowsSDK7.1_64bit

[Lars Friedrich Lars]

Hello,

 

we're compiling CUDA code in a sub-library of a bigger project which depends on ITK, VTK, Qt, RTK and a further proprietary library.

 

The CMakeLists.txt of this sub-library looks somehow like this:

 

#====================================================================

SET(OWN_LIB_NAME CBCTUtils)

SET(${OWN_LIB_NAME}_HDRS
    ...
  oraCudaImagingRingPerspectiveReorientationFilter.h
)

SET(${OWN_LIB_NAME}_SRCS
   ...
  oraCudaImagingRingPerspectiveReorientationFilter.cxx
)

CUDA_COMPILE(${OWN_LIB_NAME}_CUDA
  oraCudaImagingRingPerspectiveReorientationFilter.hcu
  oraCudaImagingRingPerspectiveReorientationFilter.cu
)

# include dirs

INCLUDE_DIRECTORIES(
  ${CBCT_BIN_DIR}
  ${CBCT_SOURCE_DIR}
  ${RTK_INCLUDE_DIRS}
  ${RTK_LIBRARY_DIRS}
)

# add utilities library

ADD_LIBRARY(${OWN_LIB_NAME} STATIC
    ${${OWN_LIB_NAME}_SRCS}
    ${${OWN_LIB_NAME}_HDRS}
    ${${OWN_LIB_NAME}_CUDA}
)

SET_TARGET_PROPERTIES(${OWN_LIB_NAME} PROPERTIES LINKER_LANGUAGE CXX)

TARGET_LINK_LIBRARIES(${OWN_LIB_NAME}
  ${RTK_LIBS}
  ${CUDA_LIBRARIES}
  ${CUDA_cufft_LIBRARY}
  ${OPENCL_LIBRARIES}
  ITKCommon
  ITKNumerics
  ORAIFTools
  ORAIFImageAccess
  ORAIFNReg2D3DDRREngine
  ORAIFNReg2D3DMathMethods
  ORAIFNReg2D3DAlgorithm
  ExperimentalORAIFImagingRing
)

# unit test

IF(CBCT_BUILD_TESTING)
  ADD_SUBDIRECTORY(${CMAKE_CURRENT_SOURCE_DIR}/testing)
ENDIF(CBCT_BUILD_TESTING)

#====================================================================

 

The problem is that obviously the underlying generated cl.exe call is incredibly long:

 

cl.exe -D__CUDA_ARCH__=100 -nologo -E -TP   -DCUDA_FLOAT_MATH_FUNCTIONS -DCUDA_NO_SM_11_ATOMIC_INTRINSICS
-DCUDA_NO_SM_12_ATOMIC_INTRINSICS -DCUDA_NO_SM_13_DOUBLE_INTRINSICS  -D__CUDACC__  /DWIN32 /D_WINDOWS /W3 /Zm1000 /GR
/EHsc -DNOMINMAX /MD /O2 /Ob2 /D NDEBUG -I"C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v4.2/include"
-I"C:/dev-libs/gdcm-2.0.14-64bit-build" -I"C:/dev-libs/itk-3.20.1/Code/Review"
-I"C:/dev-libs/itk-3.20.1-64bit-review-build/Utilities/vxl/core"
... -I"C:/QtSDK/Qt4.8.3-64bit/include/QtGui" -I"C:/QtSDK/Qt4.8.3-64bit/include/QtNetwork"
-I"C:/QtSDK/Qt4.8.3-64bit/include/QtCore" -I"C:/QtSDK/Qt4.8.3-64bit/include"
-I"C:/QtSDK/Qt4.8.3-64bit/include/QtGui" -I"C:/QtSDK/Qt4.8.3-64bit/include/QtNetwork"
-I"C:/QtSDK/Qt4.8.3-64bit/include/QtCore" -I"C:/dev/ORA-CBCT-64bit-build"
...
...
...
-I"C:/dev/ORA-CBCT-64bit-build" -I"C:/dev/ORA-CBCT-64bit-build"
-I"C:/dev/ORA-CBCT/trunk/tools" -I"C:/dev/ORA-CBCT/trunk/core"
-I"C:/dev/ORA-CBCT/trunk/core/utils" -I"C:/dev/ORA-CBCT/trunk/gui" "
-IC:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v4.2/bin/../include" "
-IC:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v4.2/bin/../include/cudart"   -D "__CUDACC__" -D "QT_DLL"
-D "QT_GUI_LIB" -D "QT_NETWORK_LIB" -D "QT_CORE_LIB" -D "QT_DLL" -D "QT_GUI_LIB" -D "QT_NETWORK_LIB"
-D "QT_CORE_LIB" -D "NVCC" -FI "cuda_runtime.h" "C:/dev/ORA-CBCT/trunk/core/utils/oraCudaImagingRingPerspectiveReorientationFilter.cu" > "C:/Users/RA-Admin/AppData/Local/Temp/tmpxft_00001cdc_00000000-7_oraCudaImagingRingPerspectiveReorientationFilter.cpp1.ii"

 

(more than 9000 characters - which is obviously too long for cl.exe "The command line is too long.")

 

 

Many of the implied included directories (which are automatically derived by CMake) are definitely not required for compiling this library - cross-checked this on the command line manually.

 

Is it possible to control (manipulate?) the generated includes in this call by invoking the one other cmake macro? Is there some other workaround besides from placing the source code of the dependent libs in folds such "C:\a" a.s.o. in order to get the resultant string shorter?

 

Thanks.

 

Lars
