有成品吗？

jwpiaoi 发表于 2020-10-29 06:55

要现成的可以用的。

wangior 发表于 2020-10-29 07:32

要成品，不要代码{:1_896:}

liking163 发表于 2020-10-29 08:00

怎么感觉那么多要成品的呢

huchhc 发表于 2020-10-29 08:01

不会怎么用的学习学习。

dojunhui 发表于 2020-10-29 08:01

这个很多软件都可以做到的吧

sssjcccz01a 发表于 2020-10-29 08:56

掌握电基础的编译技术就可以编译了

JuncoJet 发表于 2020-10-29 09:12

VC个毛线，VC能编译到 Linux ？？？
