与dylib ld的静态链接:找不到-lcrt0.o的库collect2:错误:ld返回1退出状态 [英] Static linking with dylib ld: library not found for -lcrt0.o collect2: error: ld returned 1 exit status
问题描述
我正在用gnu49编译一个qt5 c ++项目，同时使用c ++ 11标志和通常的qt框架标志与Mac OSX El Captitan上的其他dylib(armadillo，boost libs等)链接.该项目可以很好地编译，但是为了使其在其他几台机器上具有更高的可移植性，我试图静态地链接一些动态库.
我在此处描述的静态链接库(例如-static -lboost_thread)之前添加了-static标志.
I'm compiling a qt5 c++ project with gnu49 compile while linking with few other dylibs (armadillo,boost libs etc.) on Mac OSX El Captitan with c++11 flag and usual qt framework flags. The project compiles fine but to make it more portable on few other machines I'm trying to statically link few dynamic libraries.
I added -static flag before the (to be statically linked) library (e.g -static -lboost_thread) as described here.
https://gcc.gnu.org/ml/gcc/2000-05/msg00517.html
但是，出现以下错误.
ld:-lcrt0.o找不到库.collect2:错误:ld返回1退出状态
ld: library not found for -lcrt0.o collect2: error: ld returned 1 exit status
我验证了该错误仅在尝试静态链接而不是动态链接时出现.
I verified that the error comes only while trying to link statically and not with dynamic linking.
推荐答案
GCC's -static option, which you are applying, is non-positional. It enforces
static linkage of all libraries. Your linkage then fails because your system has no static version of libcrt0.o
您可能将GCC的static选项与 ld的-static选项(同义词:-Bstatic，-dn -non_shared)，
是位置.它仅影响命令行上的后续库.这是逆的
链接器的-Bdynamic选项(同义词:-dy，-call_shared).
You may be confusing GCC's static option with ld's -static option (synonyms: -Bstatic, -dn -non_shared),
which is positional. It affects only subsequent libraries on the commandline. It is the inverse of
the linker's -Bdynamic option (synonyms: -dy, -call_shared).
因此，仅通过GCC静态链接库-lfoo，-lbar ...，您可以将-Bstatic传递给
链接器(在您提及它们之前)和-Bdynamic在它们之后:
So to link only libraries -lfoo, -lbar... statically, via GCC, you can pass -Bstatic through to the
linker just before you mention them and -Bdynamic just after them:
-Wl,-Bstatic -lfoo -lbar -Wl,-Bdynamic
即使-lbar是您的最后一个库，也不要省略最后一个-Wl,-Bdynamic，因为GCC会悄悄地附加标准库
到您的链接(如您所见).
Do not omit the final -Wl,-Bdynamic, even if -lbar is the last of your libraries, because GCC quietly appends standard libraries
to your linkage (as you have found).
