Automake and CUDA, Include flags ignored

问题

以下是您要翻译的内容：

I am writing a simple automake example with CUDA but the implicit flags that should be added are ignored.

I have 2 files, main.cpp:

  1. #include <stdio.h>
  2. #include <cuda_runtime.h>
  4. int cuda_hello_launcher();
  6. int main() {
  7.     cuda_hello_launcher();
  8.     return 0;
  9. }

and aux.cu:

  1. #include <cuda_runtime.h>
  2. #include <stdio.h>
  4. __global__ void cuda_hello(){
  5.     printf("Hello World from GPU!\n");
  6. }
  8. void cuda_hello_launcher(){
  9.     cuda_hello<<<1,1>>>(); 
  10.     cudaDeviceSynchronize();
  11. }

These two files are inside the src directory.
I also have a Makefile.am in the src directory:

  1. bin_PROGRAMS = cuda_automake_example
  3. cuda_automake_example_SOURCES = main.cu aux.cpp
  4. cuda_automake_example_LDFLAGS = $(CUDA_LIBS)
  5. cuda_automake_example_LDADD = $(cuda_automake_example_LDFLAGS)
  6. cuda_automake_example_CXXFLAGS = $(CUDA_INCLUDE_FLAGS) $(CUDA_LIBS)
  8. $(info $(cuda_automake_example_CXXFLAGS))
  9. $(info $(CUDA_INCLUDE_FLAGS))
  11. .cu.o:
  12.     $(NVCC) -c -o $@ $<

And in the root directory (src directory is root/src):
I have configure.ac:

  1. AC_INIT([cuda_automake], [1.0], [])
  2. AM_INIT_AUTOMAKE([foreign])
  4. AC_PROG_CXX
  5. AC_CONFIG_HEADERS([src/config.h])
  6. AC_CONFIG_FILES([
  7.  Makefile
  8.  src/Makefile
  9. ])
  11. AC_LANG_DEFINE([CUDA], [cuda], [CUDA], [CUDACXX],
  12. [])
  14. AC_ARG_WITH([cuda],
  15.    [AS_HELP_STRING([--with-cuda=PATH], [specify CUDA installation path])],
  16.    [with_cuda="$withval"],
  17.    [with_cuda=""])
  19. if test -n "$with_cuda"
  20. then
  21.    if test "$with_cuda" = yes
  22.    then
  23.       AC_MSG_ERROR([With-cuda argument requires the path to CUDA, --with-cuda=<CUDA_PATH>])
  24.    fi
  26.    if test -z "$with_cuda"
  27.    then
  28.       AC_MSG_ERROR([If you are building with CUDA GPU support, please input the CUDA path with --with-cuda=<CUDA_PATH>])
  29.    fi
  31.    # Extract the path from the "--with-cuda" argument
  32.    cuda_path=$(echo "$with_cuda" | sed 's/--with-cuda=//')
  34.    # Check if the path is valid
  35.    if test ! -d "$cuda_path"; then
  36.       AC_MSG_ERROR([The input for cuda-path=$cuda_path is not a valid directory])
  37.    fi
  39.    CUDA_INCLUDE_FLAGS="-I$with_cuda/include"
  40.    CUDA_LIBS="-L$with_cuda/lib64 -L$with_cuda/lib -lcudart"
  41.    NVCC="$with_cuda/bin/nvcc"
  42.    CUDA_PATH="$with_cuda"
  43. else
  44.    AC_MSG_ERROR([B: $with_cuda])
  45. fi
  48. AC_SUBST(CUDA_INCLUDE_FLAGS)
  49. AC_SUBST(CUDA_LIBS)
  50. AC_SUBST(NVCC)
  51. AC_SUBST(CUDA_PATH)
  53. AC_OUTPUT

and a Makefile.am:

  1. SUBDIRS = src
  2. ACLOCAL_AMFLAGS = -I m4

When I call:

  1. automake && autoconf  && ./configure --with-cuda=/opt/nvidia/hpc_sdk/Linux_x86_64/23.3/cuda && VERBOSE=1 make

I get the following error:

I would expect the target_CXXFLAGS of the target I am building also to include the include directory containing cuda_runtime.h as well as attached to the build command (the folder has cuda_runtime.h btw that is not a problem, I checked it with ls), but apparently it is not the case, why would it be so?

得分: 1

<target_name>_CPPFLAGS 和 <target_name>_CXXFLAGS 会自动添加为目标的 C++ 标志。

当然，确保文件的扩展名正确，或者手动定义它们为 C++ 扩展名。

英文:

<target_name>_CPPFLAGS and <target_name>_CXXFLAGS are automatically added as C++ flags to the target.

Of course, make sure you have the correct filename extensions for the files or manually define the extensions as C++ extensions.
