试图用/ MT而不是/ MD重新编译第三方库的错误

我有一个项目,它有各种第三方库依赖项,其中一些是使用/ MD构建的,一些是使用/ MT构建的(因此不能混合使用)。为了解决这个问题,我试图使用/ MT重新编译其中一个库(FLTK)。但是,我在FLTK中的一些项目中收到了如下链接错误:

1>fltkd.lib(fl_call_main.obj) : error LNK2001: unresolved external symbol ___argc
1>fltkd.lib(fl_call_main.obj) : error LNK2001: unresolved external symbol ___argv
1>fltkd.lib(fl_call_main.obj) : error LNK2001: unresolved external symbol ___wargv

我能做些什么或者是否意味着库的代码是以不可能进行静态运行时链接的方式编写的?

上例中目标文件的代码是:

  dst[l] = 0;
  free(mbwbuf);
  return l;
}
