问题
Problem Background :
I have made my own library in C++ with its respective .h and .cc files. They are organized in a small directory structure as shown :
.trillBPP
├── BPSK
│ ├── finddata.cc
│ ├── finddata.h
│ ├── trigger.cc
│ └── trigger.h
├── config.h
├── config_msvc.h
├── miscfunc.cc
├── miscfunc.h
└── vector
├── binary.cpp
├── binary.h
├── mat1.cpp
├── mat1.h
├── misc.cpp
├── misc.h
├── sort.h
├── vec.cpp
└── vec.h
The header files in C++ are included simply with a call like - #include <trillBPP/vector/vec.h> or #include <trillBPP/config.h> depending on the ,file name and directory.
Problem Statement :
I'm porting this C++ code and I'm trying to create a framework in Xcode but as it turns out, Xcode flattens the directory structure and gives an error for the header file calls, the error that it gives says trillBPP/vector/vec.h file not found.
This is how the project looks like :
I've tried adding the files as Folder References instead of groups, but then it won't even recognize the header-files as header files! In Header Search Paths in Build Settings, I've also added -I and /, with no success. I came across the answer Keeping directory structure when creating frameworks in xcode , but that didn't help out because of less details for me since I'm an Xcode newbie.
So, 1. Without changing the header file call how can I tell Xcode to keep the directory structure in the final framework, 2. and also keep the header file calls the same?
