从.o制作动态库时出错 [英] Error when making dynamic lib from .o

问题描述

我正在尝试从.o文件集中创建动态lib，但是当我这样做时

I'm trying to make dynamic lib from set of .o files, but when i do

gcc -dynamiclib -current_version 1.0 mymod.o -o mylib.dylib

gcc -dynamiclib -current_version 1.0 mymod.o -o mylib.dylib

或

ld * .o -o mylib.dylib

ld *.o -o mylib.dylib

我遇到很多错误，例如:

i get a lot of errors like:

"_ objc_msgSend"，引用自: -NSObject + SBJSON.o中的[NSObject(NSObject_SBJSON)JSONFragment]

"_objc_msgSend", referenced from: -[NSObject(NSObject_SBJSON) JSONFragment] in NSObject+SBJSON.o

"operator new(unsigned long)"，引用自: MStatistic.o中的MStatistic :: instance() StatisticObserver.o中的StatisticProfileLoggingObserver :: instance()

"operator new(unsigned long)", referenced from: MStatistic::instance() in MStatistic.o StatisticProfileLoggingObserver::instance() in StatisticObserver.o

ld:架构x86_64找不到符号

ld: symbol(s) not found for architecture x86_64

能否请您帮我，如何解决它并获取我的.dylib?

Can you please help me, how to solve it and get my .dylib?

推荐答案

您可以将-undefined dynamic_lookup作为选项传递给ld，或者: -Wl,-undefined -Wl,dynamic_lookup到gcc或clang(将其传递到链接器).

You can pass -undefined dynamic_lookup as an option to ld, or:
-Wl,-undefined -Wl,dynamic_lookup to gcc or clang (which passes it to the linker).
