Cant build librocksdb.a for iOS platform in M1

[chuckern]

As the title says. Here is the code I use TARGET_OS=IOS DEBUG_LEVEL=0 make static_lib

And here is the message :

$DEBUG_LEVEL is 0

It works for me with the following flags:

You can see it warns for some flags in the errors.

Thanks for reply. One question is which project u set these flags? I cant find a ios project is rocksdb-master file.

[jurmous]

I use this project and this branch: https://github.com/marykdb/ObjectiveRocks/tree/redo It includes an Xcode project to use RocksDB as a library with an Objective C/Swift interface.

@jurmous Sorry but i still not very clear. First I want get the new .a file to fix old librocksdb.a bug in M1( for rosetta2 trans x86_64 to arm64 have a auto_roll_logger.cc error) so i try to build a new librocksdb.a in master branch and get the error ahead. after before discussion i still dont know:

1. in which project should i do the make order (this project or the project u provide)
2. if in this project(i guess), how i can fix the error at the first.
3. where i should set the flag NPERF_CONTEXT, NDEBUG in this project.

run make check first then run TARGET_OS=IOS make static_lib can get the librocksdb.a but run lipo -info find this file only have arm64. I guess this is because my mac is m1 cpu, so i will check if use Intel cpu mac can get the librocksdb.a include both x64_64 and arm64
