昨天svn迁移。然后又一次check out之后编译遇到这个错误。

从来没遇到过，直接蒙圈了......（一大堆看不到的提示）。

琢磨良久方才get到重点：

ld: file not found: /Users/zhangsuya/Desktop/root/trunk/Build/Products/Debug-iphonesimulator/wiseCloudCrm.app/wiseCloudCrm

这句话的意思是编译器想找到这个文件却没找到。

进入

/Users/zhangsuya/Desktop/root/trunk/Build/Products/Debug-iphonesimulator/目录下查看发现并没有wiseCloudCrm而是

watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvaml1c2hpamllMTIwNw==/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="">

app文件由原来英文wiseCloudCrm变成了 沟通汇

再去target下查看product name果然变成了沟通汇。问同事才知道是他改的名字（....不早说），

我把product name改为wiseCloudCrm然后点击工具栏上的product下的clean再编译正确。

同一时候又一个问题来了。即使他改了product name后他的能编译通过，而提交我更新后我的却编译不通过。原因是什么呢？

原因应该就是他没有clean。

（感兴趣的同学能够试一下）。
