For this reason我下载了C++库VTK,并在OSX环境的build
子目录中进行了本地构建。
我想使用此库(特别是我使用vtkSmartPointer
类)和Makefile
来编译项目。
例如,考虑以下源代码:
#include<iostream>
#include<vtkSmartPointer.h>
#include<vtkCallbackCommand.h>
int main()
{
vtkSmartPointer<vtkCallbackCommand> keypressCallback =
vtkSmartPointer<vtkCallbackCommand>::New();
std::cout<<"hello world\n";
return 0;
}
对于Makefile
,我从this post中的第二个答案开始,我将VTK库路径添加到该答案中:CXX = g++
# OpenCV trunk
CXXFLAGS = -std=c++11 \
-I ../VTK/Common/Core/ -I ../VTK/build/Common/Core/ -I ../VTK/build/Utilities/KWIML/ \
-I ../VTK/Utilities/KWIML/ \
-L../VTK/build/lib \
-lvtkCommon -lvtkFiltering -lvtkImaging -lvtkGraphics -lvtkGenericFiltering -lvtkIO
SOURCES := $(wildcard *.cpp)
OBJECTS := $(patsubst %.cpp,%.o,$(SOURCES))
DEPENDS := $(patsubst %.cpp,%.d,$(SOURCES))
# ADD MORE WARNINGS!
WARNING := -Wall -Wextra
# .PHONY means these rules get executed even if
# files of those names exist.
.PHONY: all clean
# The first rule is the default, ie. "make",
# "make all" and "make parking" mean the same
all: parking
clean:
$(RM) $(OBJECTS) $(DEPENDS) parking
# Linking the executable from the object files
parking: $(OBJECTS)
$(CXX) $(WARNING) $(CXXFLAGS) $^ -o $@
-include $(DEPENDS)
%.o: %.cpp Makefile
$(CXX) $(WARNING) $(CXXFLAGS) -MMD -MP -c $< -o $@
我的环境变量DYLD_LIBRARY_PATH
的值为../cmake_bin_dir/instDir/lib:../VTK/build/lib/
。当我尝试编译正在运行的
make
时,出现以下错误: ld: library not found for -lvtkCommon
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Makefile或程序中的哪个部分或过程中的哪个步骤不正确?先感谢您。
最佳答案
当前的VTK库不包含libVtkCommon.so
(请参阅软件包内容部分https://www.archlinux.org/packages/community/x86_64/vtk/)。您在寻找libVtkCommonCore.so
吗?如果是这种情况,则必须在Makefile中将-lvtkCommon
更改为-lvtkCommonCore
。其他一些包含的库似乎也是如此。
