我有一些与DCMTK有关的代码。如果我从命令行使用g ++,我可以成功构建并运行它。这是代码:
#include "dcmtk/config/osconfig.h"
#include "dcmtk/dcmdata/dctk.h"
int main()
{
DcmFileFormat fileformat;
OFCondition status = fileformat.loadFile("test.dcm");
if (status.good())
{
OFString patientsName;
if (fileformat.getDataset()->findAndGetOFString(DCM_PatientsName, patientsName).good())
{
cout << "Patient's Name: " << patientsName << endl;
} else
cerr << "Error: cannot access Patient's Name!" << endl;
} else
cerr << "Error: cannot read DICOM file (" << status.text() << ")" << endl;
return 0;
}
这是构建命令:
g++ testeapp.cxx -DHAVE_CONFIG_H -I/path_to_dcmtk/include -L/path_to_dcmtk/lib -pthread -ldcmdata -lz -loflog -lofstd -o main
我想制作一个CMakeLists.txt来在Kdevelop中构建它。这就是我目前所拥有的:
# Configure toplevel directories
SET( PREFIX ${CMAKE_INSTALL_PREFIX} CACHE PATH "Top level.")
SET( INCLUDEDIR ${PREFIX}/include CACHE PATH "Include files.")
SET( LIBDIR ${PREFIX}/lib CACHE PATH "Libraries.")
FIND_PACKAGE ( Threads REQUIRED )
# Configure DCMTK
FIND_PATH( DINIFTI_DCMTK_INCLUDE dcmtk
PATHS ${INCLUDEDIR}
PATH_SUFFIXES dcmtk
DOC "Path to the DCMTK headers." )
FIND_LIBRARY(DINIFTI_DCMTK_LIB NAMES dcmdata ofstd oflog
HINTS ${LIBDIR} ${LIBDIR})
TARGET_LINK_LIBRARIES( dinifti ${DINIFTI_DCMTK_LIB}
${DINIFTI_ZNZ_LIB}
${CMAKE_THREAD_LIBS_INIT}
z )
但是当我构建它时,它有这个错误:
/usr/local/lib/libdcmdata.a(dcfilefo.o): In function `DcmFileFormat::remove(DcmItem*)':
dcfilefo.cc:(.text+0x1788): undefined reference to `log4cplus::Logger::forcedLog(int, OFString const&, char const*, int, char const*) const'
你能帮我修一下这个错误吗?谢谢。
答案 0 :(得分:16)
看起来您希望find_library
调用使用3个单独的库填充变量DINIFTI_DCMTK_LIB
。
这不是find_library
的工作原理。 NAMES
之后的不同参数表示可以调用单个库的所有各种名称。这允许命令跨平台工作,其中相同的库可以在不同平台上被称为不同的东西。
一个小问题是您可能更喜欢在此使用PATHS
而不是HINTS
。形成文档:
...
HINTS
选项...应该是系统内省计算的路径,例如由已找到的另一个项目的位置提供的提示。应使用PATHS
选项指定硬编码猜测。
我想你想要更像的东西:
find_library(DINIFTI_DCMTK_LIB NAMES dcmdata PATHS ${LIBDIR})
find_library(OFSTD_LIB NAMES ofstd PATHS ${LIBDIR})
find_library(OFLOG_LIB NAMES oflog PATHS ${LIBDIR})
target_link_libraries(dinifti ${DINIFTI_DCMTK_LIB}
${OFLOG_LIB}
${OFSTD_LIB}
${DINIFTI_ZNZ_LIB}
${CMAKE_THREAD_LIBS_INIT}
z)
