Question

I wish to include this in my cpp file:

#include <boost/lambda/lambda.hpp>

For my Makefile Project I have selected Properties>Path and Symbols>GNU C++>Include Directories>
and added:

/opt/local/include

But I get this error when I try to build:

**** Build of configuration Default for project Main ****

make all 
g++ -O2 -g -Wall  -fmessage-length=0   -c -o Main.o Main.cpp
Main.cpp:107:35: error: boost/lambda/lambda.hpp: No such file or directory

What might the problem be?

The file /opt/local/include/boost/lambda/lambda.hpp exists.

This is my makefile:

CXXFLAGS =  -O2 -g -Wall  -fmessage-length=0

SRCS =      Main.cpp 
OBJS =      Main.o 
LIBS =      -framework CoreMIDI -framework CoreAudio -framework CoreFoundation -framework CoreServices

TARGET =    Main 

$(TARGET):  $(OBJS)
    $(CXX) -Wall -D__MACOSX_CORE__ -o $(TARGET) $(SRCS) $(LIBS)

all:    $(TARGET)

clean:
    rm -f $(OBJS) $(TARGET)

Answer 1

Should work.

CXXFLAGS =  -O2 -g -Wall  -fmessage-length=0

SRCS =      Main.cpp 
OBJS =      Main.o 
LIBS =      -framework CoreMIDI -framework CoreAudio -framework CoreFoundation -    framework CoreServices
INCL_DIR = /opt/local/include
TARGET =    Main 

$(TARGET):  $(OBJS)
$(CXX) -Wall -D__MACOSX_CORE__ -o $(TARGET) $(SRCS) $(LIBS) -I $(INCL_DIR)

all:    $(TARGET)

clean:
rm -f $(OBJS) $(TARGET)
