未定义的符号'timer_settime @@ GLIBC_2.3.3

标签: linux qemu

操作系统:Linux

我正在尝试关联mips64-softmmu/qemu-system-mips64,但这会导致错误:

./slirp/misc.o: In function `memset':
/usr/include/bits/string3.h:81: warning: memset used with constant zero length parameter; 
this could be due to transposed parameters
/usr/bin/ld: ../qemu-timer.o: undefined reference to symbol 'timer_settime@@GLIBC_2.3.3'
/usr/bin/ld: note: 'timer_settime@@GLIBC_2.3.3' is defined in DSO /lib64/librt.so.1 so   try adding it to the linker command line

/lib64/librt.so.1: could not read symbols: Invalid operation
collect2: error: ld returned 1 exit status
make[1]: *** [qemu-system-mips64] Error 1
make: *** [subdir-mips64-softmmu] Error 2

任何人都可以建议我如何解决这个问题。

发生此问题是因为rt库未链接。

在qemu目录中编辑Makefile.target,找到LIBS+=-lz,在此行下方添加LIBS+=-lrt

或者说,在本地添加了以下补丁

--- a/tools/qemu-xen/Makefile.target    2013-04-05 23:39:54.000000000 +0000
+++ b/tools/qemu-xen/Makefile.target    2013-04-25 13:54:59.360000000 +0000

QEMU_CFLAGS += $(VNC_TLS_CFLAGS)

通过添加

编辑两个文件MakefileMakefile.target来解决问题

LIBS+=-lz -lrt -lm
