C ++ LDLIBSOPTIONS makefile

Question

I want to use some other project libraries in my implementation. The project has a /common folder where the libraries are located I want to include. In my makefile under LDLIBSOPTIONS, I included the path where /common folder is located like:

LDLIBSOPTIONS=-lpci -lpthread -I../../../OtherProj/Libs/common/

Then I include one .h file like:

#include <ExampleLib.h>

However I still get

fatal error: XXX.h: No such file or directory

What am I doing wrong? Thanks.

LDLIBSOPTIONS (more conventionally LDFLAGS ) is used for specifying options to the linker. You need to specify the directory, using the -I flag, in CXXFLAGS :

CXXFLAGS += -I../../../OtherProj/Libs/common/

However given you are using non-standard names for your Makefile variables, CXXFLAGS might be called something like CXXOPTIONS , but the exact name is unknown to me.

Once this is solved you're going to be getting linker errors until you start specifying the library path using -L ; perhaps:

LDLIBSOPTIONS = -L../../../OtherProj/Libs/common/ -lpci -lpthread
