[Buildroot] update on a file in tslib not reflected after doing "Make"

[Buildroot] update on a file in tslib not reflected after doing "Make"

[Stanley]

Hi all,

I am new to embedded world and this is the first time using buildroot.
I am currently trying to solve a problem in one of the files (input-raw.c)
on tslib. However after modify/patch the file, I do a "make" in main
buildroot directory. However the changes did not reflected (tested by adding
a few texts in already existing printf statement).

eg:

input-raw.c
-------------
original file
fprint(stderr,"Unknown event type %d\n",......);

modified file
fprintf(stderr,"test\n,"Unknown event type %d\n",......);

ts_calibrate.c
---------------
original file
printf("xres = %d, yres = %d\n", xres, yres);

modified file
printf("test\nxres = %d, yres = %d\n", xres, yres);


I am using at91rm9200dk board by the way.

Here is what I did.

1) delete "tslib" folder from "build_arm" folder.
2) delete "ts" folder and "libts.la", "libts.so", "libts-0.0.so.0" and
"libts-0.0.so.0.1.1" files from "build_arm/staging_dir/usr/lib" folder. I
think this is all the lib files for tslib
3) delete "ts_calibrate", "ts_print_raw", "ts_print", "ts_test",
"ts_harvest" files from "build_arm/staging_dir/usr/lib/bin" folder. these
are the test problem.
4) do a "make" in main buildroot directory.
5) break the "make" process halfway (after extracting and patching of the
input-raw.c file before running autoconf) and modify/patch the
file(s)(modify ts_calibrate for checking) and do a "make" to resume the
process.
6) download the kernel image and rootfs into the arm9 board and run the
tslib test. (ts_calibrate). Result = printf of the original file shown in
the examples above.

For step 5, I have to break halfway because the patch I added cannot be done
before buildroot tslib patch as it will cause a patch fail for buildroot
tslib patch. I have no idea what problem is buildroot tslib patch solve but
it is did not solve the problem I encounter.

Note: Here is how I do a patch before buildroot. 1) patch file, 2) zip whole
folder, 3) copy to dl folder, 4) delete relevant files and folder, 5) do a
make. I can't do it for tslib as buildroot tslib patch will fail with the
patch I am applying.

Anyone knows how to resolve this problem?

thanks

Regards,
Stanley

If you have a build_arm folder, then you are not using the latest
release. Any reason why you are not using 2009.11?

So if I get you right, you want to add a custom patch to tslib? You can
either just place it in package/tslib together with the other patches
(make sure you name it tslib-1.0-<something>.patch), or for a quick test
just build tslib without changing anything, and then afterwards go to
output/build/tslib-1.0, change what you need to change and then remove
the stamp file (.stamp_built).

Once that is done you can just rerun make from the toplevel buildroot
dir and tslib should get rebuilt/reinstalled.

Let Buildroot does its compilation process to the end.

Then, make your modifications to build_arm/tslib-x.x/. Then, remove
the build_arm/tslib-x.x/.stamp_build file.

Re-run make.

This topic is covered in Buildroot documentation, see
docs/buildroot.html.

I tried your method and also tried creating some patches for editing the
test file. However in both cases, the changes still did not reflect.

However i did see that it got rebuilt after deleting .stamp_built file. What
I can try out now?
thanks

If you are putting new .patch files under package/tslib then you need to
rerun the patch step. The easiest way of doing this is simply to delete
the build dir (rm -rf output/build/tslib*)

Yeah, basically:

 *) If you hack directly into output/build/tslib*, then you must remove
    the .stamp_built stamp file and run make again. This will restart
    the compile process at the build step of tslib (but will *not*
    reconfigure tslib, so if you made any modifications at the
    configure level, it won't work)

 *) If you add new patches to package/tslib/, then as Peter said, the
    easiest way is to rm -rf output/build/tslib.

Thomas

Thanks for the reply.

In fact I did try both step ***separately*.

1) mod directly and remove.stamp_built file
2) create patches and rm the tslib folder and all related files (lib
file/folder, bin file) in the staging_dir.

however in both cases, the changes did not get reflected. I tried by greping
the mod statement.

eg. printf("xres = %d, yres = %d\n",...); << original
printf("test\n\n\n\n\nxres = %d, test yres = %d\n",...); << mod

then enter cmd: grep -r "test" <bin file> --> return nothing
enter cmd: grep -r "xres" <bin file> --> return 'xres = %d, yres = %d' only

Cheers,
Stanley

[Buildroot] update on a file in tslib not reflected after doing "Make"

[Stanley]

Hi all,

I know what is my problem already and manage to resolve it. It is because
the changes is not updated into the target folder ie the lib files is update
in the output/build folder but not copied into the project folder (not
installed). I think its partly because I am using fakeroot option.

anyway, I just do the steps mentioned and delete the installed_file in
/project/<project_name>/autotools-stamps/

Thanks for your help

Regards,
Stanley
