Linker Command Failure Error While Building Python3 #905

Open rahulkumaratphilips opened 2 months ago

rahulkumaratphilips commented 2 months ago

Followed the steps from readme description to build python3, but it failed and the terminal stream is as follows - `[DEBUG ] ld: warning: -undefined dynamic_lookup is deprecated on iOS-simulator [DEBUG ] ld: warning: -undefined dynamic_lookup is deprecated on iOS-simulator [DEBUG ] ld: warning: -undefined dynamic_lookup is deprecated on iOS-simulator [DEBUG ] ld: warning: -undefined dynamic_lookup is deprecated on iOS-simulator [DEBUG ] ld: warning: ignoring duplicate libraries: '-lm', '-lssl', '-lz' [DEBUG ] ld: warning: ignoring duplicate libraries: '-lm', '-lssl', '-lz' [DEBUG ] ld: warning: search path './../Support/BZip2' not found [DEBUG ] ld: warning: search path './../Support/BZip2' not found [DEBUG ] ld: building for 'iOS-simulator', but linking in dylib (/usr/local/Cellar/libb2/0.98.1/lib/libb2.1.dylib) built for 'macOS' [DEBUG ] ld: building for 'iOS-simulator', but linking in dylib (/usr/local/Cellar/libb2/0.98.1/lib/libb2.1.dylib) built for 'macOS' [DEBUG ] clang: error: linker command failed with exit code 1 (use -v to see invocation) [DEBUG ] clang: error: linker command failed with exit code 1 (use -v to see invocation) [DEBUG ] make: [python.exe] Error 1 [DEBUG ] make: Waiting for unfinished jobs....

Think the error is - linker command failed with exit code 1 (use -v to see invocation)

Please let me know if some changes needs to be done in configurations before running the build commands.

I am able to build on my system, comparing my errors warnings to yours:

[DEBUG ] ld: warning: search path './../Support/BZip2' not found
[DEBUG ] ld: building for 'iOS-simulator', but linking in dylib (/usr/local/Cellar/libb2/0.98.1/lib/libb2.1.dylib) built for 'macOS'

I am getting the first line, but not the second. In addition, my build log has:

21775 [DEBUG   ] checking for LIBB2... no

It looks like this library is not even needed. Maybe you can try uninstalling libb2 from homebrew because it may be confusing the build:

brew uninstall libb2

and try and rebuild?
