找不到/lib/libc.so.6 [英] Cannot find /lib/libc.so.6

问题描述

我正在交叉编译一个应用程序，但是链接崩溃并显示错误消息

I'm cross-compiling an application, but linking blows up with an error that it

找不到/lib/libc.so.6".

"cannot find /lib/libc.so.6".

它应该使用的libc.so.6是位于/home/work/worldcom/filesys/lib/libc.so.6的libc.so.6.我这是怎么了?

The libc.so.6 that it should be using is the one that sits at /home/work/worldcom/filesys/lib/libc.so.6. What have I got wrong here?

我的Makefile是手写的(即不是由 Autotools 生成的).为了避免出现笼统的您的Makefile损坏"的情况，以下是Makefile中的一些详细信息，可能有助于弄清这些问题.

My makefile is handwritten (i.e. not generated by Autotools). In order to avoid a blanket "your Makefile is broken" here are some details from the makefile that might help clarify.

CROSS_COMPILE = arm-none-linux-gnueabi-  
SYSROOT = /home/work/worldcom/filesys/  
DESTDIR = /home/work/worldcom/filesys/  

RELEASE_CXXFLAGS = -Os  
DEBUG_CXXFLAGS = -O0 -gstabs  
PKGCONFIG=`env ROOT=/home/work/worldcom/filesys cross-pkg-config glib-2.0 libcurl --cflags`  

CC = $(CROSS_COMPILE)gcc  
CXX = $(CROSS_COMPILE)g++  
LD = $(CROSS_COMPILE)ld  
AR = $(CROSS_COMPILE)ar  

LDFLAGS = -Wl,-O1 -Wl,-z,defs -Wl,--enable-new-dtags -Wl,--sort-common -Wl,--as-needed -Wl,--hash-style=both -L$(SYSROOT) -L$(SYSROOT)lib -L$(SYSROOT)usr -L$(SYSROOT)usr/lib -lcurl  

libobj.so: $(LIBOBJ_OBJS)  
        @echo linking $@  
        $(CXX) $^ -o $@ $(LDFLAGS) -shared $(PKG_LIBS) 

当然，还有LIBOBJ_OBJS的定义和目标，但与问题无关.

Of course there is also a definition and target for the LIBOBJ_OBJS but those are irrelevant to the problem.

推荐答案

您没有指出要使用的gcc版本，但是如果它是最新版本(我认为高于4.0.0)，则应尝试使用-sysroot标志到g ++/ld.将其指向Makefile中定义的$ SYSROOT.

You didn't indicate what gcc version you are using, but if it is a recent enough one (4.0.0 and above me thinks) you should try the -sysroot flag to g++/ld. Point it to $SYSROOT as defined in your Makefile.

假设最近的gcc版本足够，它将起作用.

Assuming recent enough gcc version, it will work.
