这似乎是我问题的正确答案,但我认为这更像是我编写makefile的方式,因为我已经有了下面链接中描述的步骤(我知道如何构建东西).

如何为使用线性代数的C++模板库Eigen编写C++项目的makefile？

错误:

SASAGeometry.h:6:22: error: Eigen/Core: No such file or directory 
SASAGeometry.h:7:20: error: Eigen/LU: No such file or directory

我的头文件中有问题的行只是:

#include <Eigen/Core>
#include <Eigen/LU>

所以这是makefile(我知道在INCLUDE行中有过分杀真):

CC = g++
BIN = .

INCLUDE = -I/usr/local/include/eigen2/ -I. -I/usr/local/include/eigen2/Eigen/ -I/home/mark/Applications/eigen/Eigen/src/ -I /usr/local/include

CFLAGS = -pipe

LFLAGS = -lm

GeomTest_OBJS = geomTest.o SASAGeometry.o

geomTest_source = SASAGeometry.cpp SASAGeometry.h sasa_transformMatrix.cpp sasa_transformMatrix.h geomSetup.cpp


geomTest    : $(GeomTest_OBJS) makefile
            $(CC) -o geomTest.o -o SASAGeometry.o $(LIBS) $(INCLUDE) $(CFLAGS) $(geomTest_source) $(LFLAGS)
            $(CC) $(LIBS) $(INCLUDE) $(CFLAGS) -o $(BIN)/geomTest geomTest.o SASAGeometry.o $(LFLAGS)

clean …

对此抱歉,但我重新打开了这个.在对特征错误进行排序之后,这种裁剪再次向上重新启动.完全相同的代码完全相同的错误.(好吧,这次编译器找到了本征头.)所以,同样的问题:

我搜索了析构函数c ++和undefined引用无济于事.但是我很确定这对我来说是一个相当简单的问题.

错误:
