Hi.

Is it possible to direct the uclinux memory image makefile to a user application makefile that is stored in a subdirectory of the user application source tree? i.e.

dir_$(CONFIG_USER_MYPROG_MYPROG_SRC)            += myprog

BACKGROUND

My application is now running well on the blackfin target board. I want to add it to the uclinux memory image. My project files are organised in this way:

myproject/src

myproject/bin

myproject/obj

etc.

myproject makefile (stored in user/myproject/src ) refers to several project subdirectories via relative links. I.e.

VPATH = ../obj

Therefore I would like the uclinux memory image makefile to 1) locate my project makefile in /user/myproject/src/, and 2) locate the resulting binary in /user/myproject/bin/ .

any ideas?

hi.

i followed the process in that document, but uclinux image make failed to locate my program's makefile which is stored in /user/myprogram/src/ .

uclinux make can locate myprogram's make if it is in /user/myprogram/ 

Appreciate if you can advise how to direct uclinux make to locate user/myprogram/src/makefile, and the resulting binary in user/myprogram/bin/mybinary

otherwise i will have to rewrite my makefile which is not good as a other people use it.

cheers,

Don't know if it will work, but did you try:

dir_$(CONFIG_USER_MYPROG_MYPROG_SRC)            += myprogram/src

the document provided already shows how to hook into the uClinux dist build system and recurse into arbitrary directories.  it also shows you the targets you must implement (all, clean, romfs) in order for things to install properly.

if you're getting an error, post the exact output.
