For this invocation of the linker, you're forcing the linker to guess what you intend, so it's telling you what it guessed.How to play Android games or run apps on Apple M1 Macbook. The fact that you specified them when building the library is irrelevant. The other stuff about -arch and -macosx_version_min not being specified is about this link command. What is it being linked to? What did you expect that command to accomplish?

In short, ld -lpacket is not a sensible link command. However, the C runtime library then has a dependency on your code providing a _main symbol, so that just moves the problem one step along. When you use the compiler to drive the link step, the compiler specifies the C runtime library, which provides start. The start routine would not normally be in your code, it would be in the C runtime library. The linker is implicitly looking for a start routine and not finding it. In any case, your library isn't sufficient to build a complete executable. That would make most sense if packet referred to a static library. Ld interprets your command ld -lpacket as a request to link a complete program executable from the object files in the specified library. so file, but when I link this in other the functions are not linked.Ĭan someone point out the mistake I'm doing? I know I don't have start function in this. Ld: symbol(s) not found for inferred architecture x86_64Įven though I'm specifying the architecture and Minimum OS X version why am I getting the error? Undefined symbols for architecture x86_64:

Ld: warning: -macosx_version_min not specified, assuming 10.6

To check if this works I run the command ld -lpacket -vĬonfigured to support archs: i386 x86_64 x86_64h armv6 armv7 armv7s armv7m armv7k arm64 (I get error 'ld: library not found for -lpacket' when I don't do so.) To allow ld to search for this I move the.
