我编译ucos的test时出现以下问题

yifenqian

[root@localhost ucos_test]# make config
building target platform is /bin/sh: line 1: test: =: unary operator expected
/bin/sh: line 1: test: =: unary operator expected
???
------------------------------------------  
I can not guess the host operation system
please set OSTYPE variable in rules.make !
------------------------------------------  
Hint: next, you can "make dep" this project now...
当我make dep
make
后没有。elf文件
怎么回事

ksh

需要设置一个环境变量
export OSTYPE=linux
