Re: [android-building] No response after “lunch" command

[Colin Cross]

The results of the finder are cached in out/.module_paths/files.db, so once
the command has completed successfully once the next runs will be much
faster.  You could try wiping that file to reproduce it again, or run with
a different value for OUT_DIR (OUT_DIR=out2 lunch ...).

 One difference I see between the old implementation using the find tool
 and the new implementation is that find seems to be able to avoiding
 calling stat on every directory entry, because the relevant information
 (whether the entry is a subdirectory or a file) is contained in the return
 from the getdents64 syscall.  The Go implementation is ignoring that
 information and has to call lstat to get it.

 It's getting stuck while trying to walk all the checked-out code
 looking for various build files.  If it was completely deadlocked then 
 it
 would have died on its own, so it's probably stuck in a loop somehow.

Re: [android-building] No response after “lunch" command

[Peter Warrington]

Hello, the command has now started to work like normal after leaving it for 
a while, so my problem might not be the same as Alessandro's. 
Unfortunately, I cannot upload a bigger stack trace until tomorrow because 
of the time in my timezone. Sorry!

Can you attach a longer strace with -T ?

Re: [android-building] No response after “lunch" command

[Peter Warrington]

Thank you! That is very interesting. In case it helps, I benchmarked my 
external HDD and it has an average read rate of 92.0 MB/s and an average 
access time of 16.37 msec. However, I didn't have any trouble with this 
previously.

 When "lunch" is stuck, the output of strace ends with "wait4(-1,". All 
 the remaining part appears when I abort "lunch" with CTRL+C.

 Maybe this issue is due to the fact that I'm using a guest in 
 Virtualbox?

Re: [android-building] No response after “lunch" command

[Colin Cross]

Nothing looks wrong in that strace, it is making forward progress.  It
needs to read every directory and stat every file in the tree, is your
filesystem very slow for some reason?

One difference I see between the old implementation using the find tool and
the new implementation is that find seems to be able to avoiding calling
stat on every directory entry, because the relevant information (whether
the entry is a subdirectory or a file) is contained in the return from the
getdents64 syscall.  The Go implementation is ignoring that information and
has to call lstat to get it.

Attached is a partial strace.

 Hello, I'm trying to build the Android source code for my Hikey 960 
 board.
 I'm following this video tutorial 
 https://www.youtube.com/watch?v=RD_NZRKiZBU in parallel to the 
 official Android guide 
 https://source.android.com/setup/devices#hikey-boards.


 Everything went fine until I reached the command "lunch 
 hikey960-userdebug". It blocks, without returning any output. I left it 
 "working" for 1 hour and then I aborted it (even if I know that this 
 command should take few seconds). If I execute only "lunch" it shows the 
 list of available build targets, and when I select "hikey960-userdebug" it 
 blocks. When I abort it with CTRL+C, it says "Still alive, killing 
 subprocesses" and then it shows a lot of messages referring to threads. 
 Here is the screenshot https://ibb.co/k32KQR
 I noticed that also the "make" command (inside the AOSP directory) has 
 the same behaviour.


 This is the list of commands I've used during the process:


 sudo apt-get install openjdk-7-jdk

 sudo apt-get install git-core gnupg flex bison gperf build-essential 
 zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 
 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev ccache 
 libgl1-mesa-dev libxml2-utils xsltproc unzip

 mkdir output

 export OUT_DIR_COMMON_BASE=/home/brucedh/output/

 mkdir ~/bin

 PATH=~/bin:$PATH

 curl https://storage.googleapis.com/git-repo-downloads/repo > 
 ~/bin/repo

 chmod a+x ~/bin/repo

 mkdir dev

 cd dev

 mkdir hikey960

 cd hikey960

 git config --global user.name ""

 git config --global user.email ""

 repo init -u https://android.googlesource.com/platform/manifest -b 
 master

 repo sync –j4

 git clone https://android.googlesource.com/kernel/hikey-linaro

 cd hikey-linaro

 git checkout -b android-hikey-linaro-4.9 origin/android-hikey-linaro-4.9

 make ARCH=arm64 menuconfig

 make ARCH=arm64 hikey960_defconfig


 PATH=/home/brucedh/dev/hikey960/prebuilts/gcc/linux-x86/aarch64/aarch64-linux-android-4.9/bin/:$PATH

 make ARCH=arm64 CROSS_COMPILE=aarch64-linux-android- -j4

 cp arch/arm64/boot/dts/hisilicon/hi3660-hikey960.dtb 
 ../device/linaro/hikey-kernel/hi3660-hikey960.dtb-4.9

 cp arch/arm64/boot/Image.gz 
 ../device/linaro/hikey-kernel/Image.gz-hikey960-4.9

 cd ~/dev/hikey960

 . ./build/envsetup.sh

 lunch hikey960-userdebug



 I'm using Ubuntu 16.04 LTS as guest on Virtualbox. I tried to do all 
 the process once again from the beginning with a new virtualbox image, but 
 I found the same problem.

 Thanks in advance!

There will be at least one goroutine with a different stack.  Can you
capture the full log and put it somewhere I can see?

[android-building] Re: Android building questions problems

[Glenn Kasten]

For the tablet porting questions, please ask at android-porting group 
instead of android-building.

For the minimum host configuration question, I suspect that 8 GB of RAM is 
insufficient.
https://source.android.com/setup/requirements
says minimum of 16 GB RAM for VMs, but I think that is also true for 
non-VMs.
I would recommend much more than 16 GB if you can get it. For example 64 GB 
is better.

I worked around with following method:
rm -fr kernel/hikey-linaro.git
cd kernel
git clone --mirror https://android.googlesource.com/kernel/hikey-linaro

do the same thing for platform/external/nanopb-c 
 project as well

[android-building] Re: Actual size of download when 'repo sync' is invoked

[Les Potter]

Sorry for the late info, but I figure that since it can't be found anywhere 
else, this would be an appropriate place.

Just used "repo sync" to pull "master" of AOSP

$du -s -BM /developer/master
59465M  /developer/master

Re: [android-building] No response after “lunch" command

[Alessandro Brucato]

This is the output of strace attached to the process in which I execute 
"lunch".




When "lunch" is stuck, the output of strace ends with "wait4(-1,". All the 
remaining part appears when I abort "lunch" with CTRL+C.

Maybe this issue is due to the fact that I'm using a guest in Virtualbox?

[android-building] Android building questions problems

[Louis Paquet]

Hi,

I'm posting here because I have a few questions and some problems.

Me and some friends a trying to create are own tablet and our android rom.

So we wanted to try and play a bit with AOSP 7.1.1 to see what we can do 
and start working on it, but we can't seem to build it, at first we got RAM 
issues with a java error, we seem to have resolved this error but now when 
we try to build we get subcommand failed. It sometimes fails at 1% or it 
can also fail at 60%. I seem to have install all the necessary dependencies.

We are working on linux mint, we are trying to build AOSP 7.1 with a Intel 
Core i7-5600U 2.60GHz and 8GB of ram. We put AOSP on a external 1To drive 
because we want to build a server to access it in remote.

Here are some additional questions if someone can help


   - We will need a kernel for our tablet, what can we use do we have to 
   compile it with AOSP,  i've read a bit about kernels but didn't get to it.
   - Are there things we must do or mustn't do

If you have any tips i'll take everything

Thanks

Re: [android-building] No response after “lunch" command

[Peter Warrington]

Hello, I've had this same problem building for a different target too. When 
I press ctrl+c to exit I got the following output repeated:

goroutine 6171 [chan send]:
android/soong/finder.(*semaphore).Lock(...)
build/soong/finder/finder.go:589
android/soong/finder.(*threadPool).Run.func1(0xc4200f0500, 0xc420f5e720)
build/soong/finder/finder.go:626 +0x41
created by android/soong/finder.(*threadPool).Run
build/soong/finder/finder.go:625 +0x62

This seems to suggest that it is having trouble finding the files on my 
external HDD. A workaround of this in theory would be to disable "Soong" 
which replaces makefiles (See 
https://android.googlesource.com/platform/build/soong/) but I do not know 
if this is possible or how to do it.
