c++ - 如何使用CMake交叉编译C++ DCMTK项目(从Ubuntu到Windows)

标签 c++ cmake compiler-errors cross-compiling dcmtk

我正在尝试交叉编译我发现的最简单的DCMTK示例，并且可以将其构建。
我正在运行Ubuntu 18.04.4 LTS以使用x86_64-w64-mingw32进行交叉编译。

我也检查了这些答案和示例，但它们对我没有用:

  • CMake: Cross-compiling linux-to-windows with MinGW does not find some system headers
  • https://gitlab.kitware.com/cmake/community/-/wikis/doc/cmake/cross_compiling/Mingw

    • 这是项目的唯一文件(main.cpp):
    #include "dcmtk/config/osconfig.h"
#include "dcmtk/dcmdata/dctk.h"

using namespace std;
int main()
{
    DcmFileFormat fileformat;
    OFCondition status = fileformat.loadFile("sample.dcm");
    if (status.good())
    {
        OFString patientName;
        if (fileformat.getDataset()->findAndGetOFString(DCM_PatientName, patientName).good())
        {
            cout << "Patient's Name: " << patientName << endl;
        } else
            cerr << "Error: cannot access Patient's Name!" << endl;

        OFString patientID;
        if (fileformat.getDataset()->findAndGetOFString(DCM_PatientID, patientID).good())
        {
            cout << "Patient's ID: " << patientID << endl;
        } else
            cerr << "Fatal Error: cannot access Patient's ID!" << endl;

    } else
        cerr << "Error: cannot read DICOM file (" << status.text() << ")" << endl;
    return 0;
}

    这是我的CMake.txt配置文件:
    cmake_minimum_required(VERSION 2.8)
PROJECT(test1DCMTK)

add_executable(${PROJECT_NAME} "main.cpp")

SET(DCMTK_DIR /usr/local/include/dcmtk)

ADD_DEFINITIONS(-D_REENTRANT)

INCLUDE_DIRECTORIES(${DCMTK_DIR}/include)
LINK_DIRECTORIES(${DCMTK_DIR}/lib)

TARGET_LINK_LIBRARIES(test1DCMTK ofstd dcmdata)

    我正在使用此工具链文件:
    ### CMAKE cross compile settings for Windows running from Ubuntu 18.04.4 LTS x86_x64 amd64 ###

# programs in the host environment
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)

    当我使用CMake配置时，得到以下信息:
    The C compiler identification is GNU 7.3.0
The CXX compiler identification is GNU 7.3.0

    但是，当我尝试构建代码时，这是我得到的:

    但是，该库存在:
    (base) yo@MiPC:/usr/local/include/dcmtk/config$ ls /usr/local/include/dcmtk/config/os*
/usr/local/include/dcmtk/config/osconfig.h

    那么，我在做什么错呢？我应该怎么做才能使其正常工作？

    我尝试了@squareskittles的答案，尝试构建时得到了这个:

    最佳答案

    您的CMake正在添加dcmtk包含目录，如下所示:

    SET(DCMTK_DIR /usr/local/include/dcmtk)
INCLUDE_DIRECTORIES(${DCMTK_DIR}/include)

    结果如下:
    /usr/local/include/dcmtk/include

    然后，您的main.cpp文件包括dcmtk/config/osconfig.h，该文件(结合了两个路径)表明标题位于此处:
    /usr/local/include/dcmtk/include/dcmtk/config/osconfig.h

    这似乎不正确。尝试在CMake文件中仅包括/usr/local/include:
    INCLUDE_DIRECTORIES(/usr/local/include)

    作为附带说明，CMake为DCMTK提供了Find Module，因此它将尝试查找库并为您设置一些变量。您可以尝试类似的方法，但是根据您的CMake版本，结果可能会有所不同:
    cmake_minimum_required(VERSION 2.8)
PROJECT(test1DCMTK)

find_package(DCMTK REQUIRED)

add_executable(${PROJECT_NAME} main.cpp)

SET(DCMTK_DIR /usr/local/include/dcmtk)

ADD_DEFINITIONS(-D_REENTRANT)

# Use the INCLUDE_DIRS variable populated by the DCMTK find module.
INCLUDE_DIRECTORIES(${DCMTK_INCLUDE_DIRS})

# Use the LIBRARIES variable populated by the DCMTK find module.
TARGET_LINK_LIBRARIES(test1DCMTK ofstd ${DCMTK_LIBRARIES})

    如果此操作成功找到DCMTK，则DCMTK_INCLUDE_DIRS可能会包含，包括DCMTK所需的所有包含目录，而不仅仅是您手动添加的包含目录。这可能有助于解决您看到的编译器错误。
