问题:Undefined symbols for architecture x86_64: ld: symbol(s) not found for architecture x86_64 问题原因:所用的库不支持 X86_64架构 解决方法:在Target —> BuildSetting —> Architectures中修改为$(ARCHS_STANDARD_32_BIT)如下图:
今天在运行一个老ios项目的时候,突然报错:No architectures to compile for (ONLY_ACTIVE_ARCH=YES, active arch=x86_64, VALID_ARCHS=i386), 网上搜了一下资料,有多种方法,但有些没有用,后来终于找到了一种方法,解决了这个问题,现把步骤记录一下: 1.在Project target里“Architectures”设置为“Standard (armv7,armv7s)” :2.修改在Project target
Assembly on x86_64 Linux Some instructions in Intel assembly set are invalid in x86_64 env. e.g. aaa push eax ... Solutions Use 64-bit instructions instead.(You can refer to Intel developer manual) Add 32-bit options: For nasm: nasm -f elf32 xxx.asm
当出现 linker command failed with exit code 1 (use -v to see invocation) 的错误总结,具体内容如下: Undefined symbols for architecture x86_64: "_OBJC_CLASS_$_AppDelegate", referenced from: objc-class-ref in main.o ld: symbol(s) not found for architectu
