Add external sources directory

[garyservin]

Hi, I'm trying to add an external directory which contains some source files for a project, my project's folder structure is the following

• /project
  • /my_lib
  • my_lib.cpp
  • my_lib.h
  • makefile
  • main.cpp

The makefile has the following

PROJECT         := HelloWorld
DEVICES         := LPC1768
GCC4MBED_DIR    := <gcc4mbed_path>
NO_FLOAT_SCANF  := 1
NO_FLOAT_PRINTF := 1

include $(GCC4MBED_DIR)/build/gcc4mbed.mk

If my_lib folder is inside each project folder I can compile it fine, but it weights about 5M so it's not practical to have it copied in each directory. I would like to have something like

• /my_projects
  • /my_lib
  • my_lib.cpp
  • my_lib.h
  • /project1
  • makefile
  • main.cpp (which uses my_lib)
  • /project2
  • makefile
  • other_main.cpp (which uses my_lib)

Is there a simple way to do this in the makefiles?

Thanks in advance!

There is currently no support for this in gcc4mbed. You currently have to do this the way that you originally describe.

I will keep this issue open to consider for the next gcc4mbed release. It should be possible to do this in a fashion similar to how the mbed SDK libraries are built.

Thanks,

Adam

I have added USER_LIBS support with commit bd4695b2fae2bf96dbf71edb2aeb66de233b0859 in the working branch. I will close this issue once I have merged into master during the next release.

Now merged into master.

Hi Adam,

I do have an issue with the USER_LIBS parameter in case a lib contains subfolders with relevant source files. I just exported the HTTPClient lib from the old mbed website, which uses source-subfolders. Is there a quick fix for this?

Thanks,

Daniel

Update: Nevermind. I found a configuration issue on my side.
