Re: [android-building] Re: missing and no known rule to make it

['Dan Willemsen' via Android Building]

The code that prints that out is in ninja
, but
it really won't help to debug it from there -- it has printed everything it
knows.

ninja: error:
> '/home/vamsi/ctos/out/target/common/obj/JAVA_LIBRARIES/sap-api-java-static_intermediates/classes-header.jar',
> needed by

This error message would be far better using Android.bp (the Bluetooth app
here was migrated in Android 11). It's very hard to get the makefiles to
produce a better error, so you have to work backwards from the files being
referenced. In this case the Bluetooth(*_intermediates) app(APPS) is
depending on something from the sap-api-java-static library, but that
doesn't exist. Usually that means that the sap-api-java-static library is
missing or not configured correctly.

[android-building] Re: missing and no known rule to make it

[Mutyala N V Durga Ashok]

Hi Dan / Krishna,

ninja: error: 
'/home/vamsi/ctos/out/target/common/obj/JAVA_LIBRARIES/sap-api-java-static_intermediates/classes-header.jar',
 
needed by 
'/home/vamsi/ctos/out/target/common/obj/APPS/Bluetooth_intermediates/classes-full-debug.jar',
 
missing and no known rule to make it

We are trying to search this log under build directory in AOSP and couldn't 
able to find it. Tried with "missing" , "no known rule ", "needed by" but 
nothing works

Could you help me to point to the code where you are printing this log  ?

[android-building] Re: "Unable to start RBE reproxy" when build android13 with error log "Unavailable desc"

[Faqiang Zhu]

Hi  力召,

Thank you, now the reproxy can be started.

then I have another issue:
The client distribute actions to the service, the service schedules the 
actions to the workers, the workers does the actions.
In android build system, there is a limitation of using the host 
installed tools, many tools under "prebuilts/" directory like clang++ is 
used, how can a worker get the environment as the local build?

I set "RBE_CXX_EXEC_STRATEGY" to be "remote" then try to build a test 
module with RBE, the log shows that it blocks on "clang++ 
test_source_file.cpp", while on the service end, it can be known that there 
is input requests,  but the worker seems does nothing.
I guesss it's related to the clang++ tool, although I installed clang++ 
on the worker machine. but android should use its own.

Best Regards,
Zhu Faqiang.

Wow, 18 minutes, that's unbearable.
