【问题描述】:
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。
我想用这个库编译一个项目(特别是我正在使用类vtkSmartPointer)和Makefile。
以下面的源代码为例:
#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,我在其中添加了VTK 库路径:
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 的值是../cmake_bin_dir/instDir/lib:../VTK/build/lib/。
当我尝试编译运行 make 时,我收到以下错误:
ld: library not found for -lvtkCommon
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Makefile 或程序中的哪一部分或流程中的步骤不正确?
提前谢谢你。
