busybox的静态编译问题

albert198511

busybox-1.9.2版本：

Build Options 中选择：
  

Build BusyBox as a static binary (no shared libs)                                │ │
  [ ] Build shared libbusybox                                                          │ │
  

Build with Large File Support (for accessing files > 2 GB)     

执行make命令，出现如下错误：
[root@localhost busybox-1.9.2]# make
cat: /dev/null: 没有那个文件或目录
  SPLIT   include/autoconf.h -> include/config/*
  GEN     include/bbconfigopts.h
  HOSTCC  applets/usage
  GEN     include/usage_compressed.h
  HOSTCC  applets/applet_tables
  GEN     include/applet_tables.h
  CC      applets/applets.o

make[1]: *** [applets/applets.o] 错误 1
make: *** [applets] 错误 2

查看applets/applets.c文件：
[root@localhost busybox-1.9.2]# vi applets/applets.c
#include <assert.h>
#include "busybox.h"

/* Apparently uclibc defines __GLIBC__ (compat trick?). Oh well. */
#if ENABLE_STATIC && defined(__GLIBC__) && !defined(__UCLIBC__)
#warning Static linking against glibc produces buggy executables
#warning (glibc does not cope well with ld --gc-sections).
#warning See sources.redhat.com/bugzilla/show_bug.cgi?id=3400

#warning If you still want to do it, remove -Wl,--gc-sections

#endif

#if ENABLE_BUILD_LIBBUSYBOX
int main(int argc, char **argv)
{
    return lbb_main(argc, argv);
}
#endif
#if ENABLE_STATIC && defined(__GLIBC__) && !defined(__UCLIBC__)-----这句在哪可以改设置？

谢谢！
