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

[watermirror]

hi , i am building Chromium Embedded Controller (EC) Development.

firstly, i got the code follow http://www.chromium.org/chromium-os/developer-guide.also , i have build the arm-generic successfully.

then i go to the trunk/src/platform/ec (execute cros_sdk first), follow the steps in as http://www.chromium.org/chromium-os/ec-development.

i execute command as:

1)git checkout cros/firmware-snow-2695.B
2) make -j BOARD=daisy

i got errors like this:

  HOSTCC  util/ectool
  BUILDCC util/ec_uartd
  BUILDCC util/stm32mon

collect2: error: ld returned 1 exit status
make: *** [build/daisy/util/stm32mon] Error 1


how could i solve it?

Ok I got it, you are using an old EC branch (cros/firmware-snow-2695.B) with a new ToT chroot (which has a newer version of libftdi aka libftdi1).

You need to backport the support for libftdi1 (which was the following changelist : https://chromium-review.googlesource.com/#/c/47875/  ) to get a working setup. something like :

git cherry-pick 357e5083

But you will get the same issue with vboot_reference repository (which is ToT and not compatible with EC branch), you would need to switch that repository to cros/firmware-snow-2695.B *and* install it.

If you want to do development on an old branch, it might be easier to
just create a brand new chroot just for that branch. You can do
something like:

repo init -u <url> -b firmware-snow-2695.B
repo sync

in a new directory, which will ensure that the correct branch gets
checked out in all the appropriate repositories. Then you would use
your original chroot to build chromium os images and use the new
chroot solely for firmware/ec development. The downside of this
approach is that you end up with an entire separate copy of the source
but the upside is that you don't have to hunt down all the
dependencies that may have changed since the branch was created.

Hi, i am new. i can not understand the old EC branch and new ToT chroot.
i am following the http://www.chromium.org/chromium-os/ec-development and http://www.chromium.org/chromium-os/ec-development to build the EC. it seems these two pages out of date. is there any more recent information?

he means you can't easily check out an old branch in two repos and try to build it using the newer chroot

so when you do `repo init` the firs time, pass in the right branch name
