Has anyone built AOSP with Ubuntu 18.04?

[Jacob Abrams]

Curious if anyone out there tried to build android on Ubuntu 18.04? If so any notes you can provide on the experience?

Thanks.

[Antonio Jesús Rivas Berral]

I have built Android P GSI without problems , if you try to build CAF ROM you will get flex error , its easy to solve just type the error at github search bar and you´ll find a repo with the fixed file.

[Jacob Abrams]

Thanks for the confirmation. I'm having trouble with the repo forall command, does it work for you? I get this error:

repo forall -c 'pwd'

Okay lesson learned, do not use snap to install stuff, prefer apt. I reinstalled repo command and moved on.

Now I did repo init with branch android-8.1.0_r29 and checked out that branch on all repositories and began to build aosp_arm.

Something wrong with flex. Anyone seen something like this?

[Dan Willemsen]

The old flex prebuilt has apparently been causing problems on newer OSes. I've recently replaced it on master with one built with our standard host toolchain: https://android.googlesource.com/platform/prebuilts/build-tools/+/959ea284c41b1be5283f9eca421f1124c1ff5100/linux-x86/bin/

It doesn't have any dependencies, so you should be able to just copy that file over your old one. That should be the same version as the old prebuilt, though we're likely to be updating to a newer version of flex shortly, so make sure you get the right version. (https://android-review.googlesource.com/c/platform/external/flex/+/695681)

Let me know if you run into any other issues -- we can't do much about released versions (see https://android.googlesource.com/platform/build/+/master/tools/docker for a workaround), but I am fixing issues as they come up in master.

Thanks,

Dan

[Yogi nit]

Enter this in terminal :

export LC_ALL=C

before giving the make command.

[Jacob Abrams]

Okay solved the flex problem.

Set env variable like so:

export LC_ALL=C

Same thing applies to Arch Linux (and basically any OS with that issue)

I hope it will be fixed in AOSP so that we don't need the workaround.

[Dan Willemsen]

Has anyone here tested with AOSP master? I believe this should be fixed.

1) The new flex binary doesn't even have NLS enabled, so it shouldn't be trying to load locale data.

2) I sanitize the various LC_* options to only pass through LC_MESSAGES, which should produce more reliable builds (LC_COLLATE was causing some build differences, etc), but retain any possible translations for error messages and the like.

Have tried building with Ubuntu 18.04, not working for me. I keep getting this error below and cant find how to fix this issue.

Hi,

all locale related problems can be avoided as explained by Jacob Abrams

export LC_ALL=C

M.

[Nitin Pathak]

It is the same error Jacob was getting.
Before giving the make/lunch/brunch command

enter this in terminal

export LC_ALL=C

[Simao Gomes Viana]

I did this:

https://git.halogenos.org/halogenOS/android_build_soong/commit/df6b84fa232f2620b6b148213171b7e16656ce5d

https://git.halogenos.org/halogenOS/android_build_make/commit/5814bf7e215f97487231cddaffa92b7b86314489

https://git.halogenos.org/halogenOS/android_external_flex

compiles flex from source when the build starts which works without specifying LC_ALL=C

[中外]

for error information "flex-2.5.39: loadlocale.c:130: _nl_intern_locale_data: Assertion `cnt < (sizeof (_nl_value_type_LC_TIME) / sizeof (_nl_value_type_LC_TIME[0]))' failed."

you need run below command before compile 

export LC_ALL=C
