[Abhijeet Salunke]

Thanks for the answer Dan Willemsen.. And Yes it was my mistake when I said
I am using El Capitan actually I have updated the system and currently its
Mac OS X Catalina. I am working with Linux VM as suggested by you.

Re: [android-building] Is there tool like androidmk to convert Android.bp to Android.mk?

['Dan Willemsen' via Android Building]

It would be simple enough to write one that handles a few use cases, but
no, I don't know of one. The Android.mk that ndk-build uses was never the
same format as the Android.mk used by the platform builds -- they just
happened to share some names (and both used make).

Re: [android-building] how to distribute android 10/11 ?

['Dan Willemsen' via Android Building]

GOMA support has been removed on the AOSP master branch, and has been
replaced with RBE.

 Hi,

 I faced one problem, i have tried to solve it many days.


 AOSP compile on one powerful physical server(36U128G) is fast .
 Because my company has so many people need to compile AOSP on the server,so
 it is busy all the time , and I do not have money to buy more.But the VM I
 can request more.So I want to use VM on the cloud to compile AOSP.

 I have some distribute compile experiences in other c/c++ projects. So
 I'm thinking is there any way to compile AOSP in distribute way?exp: use
 many VMs for one AOSP build.

 I noticed there had topic long time ago :
 https://groups.google.com/forum/#!searchin/android-building/distcc%7Csort:date/android-building/_YJNwvq6FtY/EENyTx4Elk4J

 I tried distcc , but failed . AOSP switching to clang, but distcc
 support clang not ok.
 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=926884


 So, I want to know ,AOSP in google , how to solve the long build time
 ?use more powerful physical server? or you have your own distribute
 compile solution?

Re: [android-building] [Help] clang error while building on Mac OS X El Capitan

['Dan Willemsen' via Android Building]

Oh, I forgot El Capitan is MacOSX 10.11, which is probably old enough to be
supported on that branch. But the MacOS 11.1 SDK shouldn't work on that,
and the screenshot claims that you're running 10.15.7 (Darwin 19.6.0). So
something doesn't line up here.

Regardless, the Linux VM is probably your best bet -- platform builds on
Mac aren't entirely full-featured anyways (close enough for most
development, but a handful of things can be missing).

Re: [android-building] [Help] clang error while building on Mac OS X El Capitan

['Dan Willemsen' via Android Building]

Older versions of Android don't build with newer versions of MacOS (the
inverse works, you can build newer android versions with older MacOS
versions, though that's not usually interesting except for CI servers)

If you really need to build a 4+ year old android version on your Mac, then
your best bet is probably to use a Linux virtual machine. That may be
faster anyways.
