iOS开采编写翻译报错,常见报错的化解办法

fsurczqtrxdfujfaheklacpbsecc/Build/Products/Debug-iphonesimulator/libRCTJCoreModule.a(RCTJCoreModule.o))
was built for newer iOS version (10.3) than being linked (8.0)

fsurczqtrxdfujfaheklacpbsecc/Build/Products/Debug-iphonesimulator/libRCTJCoreModule.a(RCTJCoreModule.o))
was built for newer iOS version (10.3) than being linked (8.0)

问题1:ARC与MRC混编

1、报错与警报

一、错误代码:No architectures to compile for (ONLY_ACTIVE_ARCH=YES,
active arch=x86_64, VALID_ARCHS=armv7 armv7s)

build 那个target的时候命令行报错。能够在 build setting
中,寻找bitcode,并吧 enable bitcode 设置为 NO.

2、ld:framework not found IOKit

终点输入以下贰行内容:

cd/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.1.sdk/System/Library/Frameworks/IOKit.framework

sudo ln -s Versions/A/IOKit .

里头,如果那贰个,从文件夹中稳步张开看下路线对不对,要是像有修改Xcode名称的,注意如
“xcode 5” [有空格” “的回想在极限中加多 “\”这些标识];

三、程序没难点,运维报错:Directory not empty

投身/Users/你计算机名/Library/Developer/Xcode/DerivedData下的缓存文件占异常的大的缓存空间,纵然长日子不删除xcode下的缓存文件,就会促成硬盘空间越来越小直到Directory
not empty。删除了缓存文件再运转就不会再报错。

仍然,间接clean1遍就能够了。

4、假如遇到编写翻译错误类似:Undefined symbols for architecture armv7:

“_OBJC_CLASS_$_ASIHTTPRequest”,先反省上述的借助代码是还是不是已投入编写翻译列表,如未参与,依次点击Target->Build
Phases->Compile Sources,点击后面部分“+”增加上述代码。

假设遇上编译错误类似:Undefined symbols for architecture armv7:
“_inflateEnd”, referenced
from,则应当是不够依赖libz.dylib,增加格局:依次点击Target->Build
Phases->Compile
Sources,点击尾部“+”,在弹出的列表中输入libz,增加寻找结果中前卫版本就能够。

5.but did not return a nonzero exit code to indicate failure

日志类似:

解决:

选择 Build Settings 菜单,把compress PNG files 改成NO。

6.Undefined symbols for architecture i386:

日志类似:(缺乏BJGKPaintMapViewController文件的引用)

澳门葡京 3

案由:xcode项目import文件时,会依赖project.pbxproj来寻觅,查找不到文件的引用则会有上述的荒谬。图中正是BJGKPaintCommand文件对BJGKPaintMapViewController类的引用找不到。日常在几人合作开拓的时候,svn提交不专门的学业导致的project.pbxproj产生错误,使得文件的引用不在project.pbxproj文件中。

减轻方案:

a.点击Build Phases,要是是不够的xxx是类名,则在Complie
Sources中参预该文件。若缺乏类库,则在Link Binary With
Libraries中参预该类库。比如图中是缺乏“BJGKPaintMapViewController”,这几个是类名。

b.或许直接把要求引用那一个紧缺类/库的原来的书文件去掉引用,笔者就是多调用了BJGKPaintCommand类文件,所以把它去掉,也就不须要补上BJGKPaintMapViewController类的引用了。

iOS开采编写翻译报错,常见报错的化解办法。相见类似以下报错:

Undefined symbols for architecture i386:

“_sqlite3_bind_blob”, referenced from:-[FMDatabase
bindObject:toColumn:inStatement:]inFMDatabase.o”_sqlite3_bind_double”,
referenced from:-[FMDatabase
bindObject:toColumn:inStatement:]inFMDatabase.o”_sqlite3_bind_int”,
referenced from:-[FMDatabase
bindObject:toColumn:inStatement:]inFMDatabase.o”_sqlite3_bind_int64″,
referenced from:-[FMDatabase
bindObject:toColumn:inStatement:]inFMDatabase.o”_sqlite3_bind_null”,
referenced from:-[FMDatabase
bindObject:toColumn:inStatement:]inFMDatabase.o”_sqlite3_bind_parameter_count”,
referenced from:-[FMDatabase
executeQuery:withArgumentsInArray:orDictionary:orVAList:]inFMDatabase.o-[FMDatabase
executeUpdate:error:withArgumentsInArray:orDictionary:orVAList:]inFMDatabase.o

………

地点的情趣是Link Binary With Libraries 中并未有增多“libsqlite3.dylib”,但是Xcode7中唯有对应的“*.tbd”,而没有“*.dylib库”,咋办吧?

方法①:

“Link Binary With Libraries”中式点心击 “+”,点“Add
Other”,那时候按下“Command+Shift+G”,输入“/usr/lib”实行寻觅,可以看看
“libsqlite叁.dylib”,双击增添完结。

方法②:

点项目,TAGERT -> Build Setting -> Lingking -> Other Linker
Flag ,在里头增加一行字符: “-lsqlite三”。 加多达成。

7、难点: ld/ warning/ directory not found for
option从品类中剔除了有个别目录、文件之后,编写翻译出现警示音讯:***
ld:
warning: directory not found for option“XXXXXX”:***

偶然已经从品类中剔除了文件和文书夹依旧报那些警示,固然尚未爆发错误,不过看着很不舒服。。

去掉警告的点子如下:

壹取舍工程, 编写翻译的

2选择 Build Settings 菜单

三如下查找 Library Search Paths 和 Framework Search Paths,
删掉编写翻译报warning的门路即OK。

八.Xcode七打包,iOS玖真机闪退,怎么着消除?

答:点击链接->【Xcode7打包,iOS九真机闪退,怎么样化解】

九.报错如下:

Undefined symbols for architecture i386:

std::__basic_file::is_open() const”, referenced from:…

或者“std::basic_string, std::allocator >::find(wchar_t const\,
unsigned long, unsigned long) const”, referenced from*:”…

接下来后边一大堆的以“std:”起先的叙述…

赶尽杀绝方案:项目名 -> Build Phases -> Link Binary With
Libraries,

将libstdc++.dylib换到libstdc++.陆.0.玖.dylib就能够了。

点击“Finder->前往->资源库->Developer->Xcode->DerivedData**”**,【看不到“财富库”?点击“前往”,看到菜单栏时,按“Option”就观看了.】

依然点击“Finder->前往->前往文件夹**”,输入:

”/Users/你眼下登入的用户名/Library/Application Support/One plusSimulator/“

a.App被XCode Build在这里:

点击“Finder->前往->资源库->Developer->Xcode->DerivedData”,

或者,点击“Finder->前往->前往文件夹”,输入:
/Users/你目前登入的用户名/Library/Developer/Xcode/DerivedData

b.连接真机生成的文本,能够全方位删掉也许把不常用的本子删掉,再一次连接装置会自动生成:

“~/Library/Developer/Xcode/iOS DeviceSupport”

c.app打包生成的公文,能够删掉不必要的连串打包文件:

“~/Library/Developer/Xcode/Archives”。

如上都得以把不须要的app项目删除。或许定期删除旧的品种。

三.Xcode品种模拟器上png格式的本地图片不奇怪展现,真机调节和测试不彰显:

可能有2个原因:

.图片的上马状态,不是png的,被自个儿一贯就改成png了。那样效仿器OK,真机就有题目。

能够采用Mac
系统自带的图形预览导出一下,(就是双击图片,点击左上角:文件->导出->png格式),再双重导入就行了。

.真机上文件名是有别于轻重缓急写的,而模拟器上边是不区分的,所以模拟器能够,真机不行;


**更新–>**

四.项目改变1部分财富照旧修改部分数码后,再一次运维模拟器依旧原先的机能,未有产生变化:(比方提醒找不到一些头文件。)

按一下:Product -> Clean ,应该是割除一下再编写翻译;

老是项目有数据修改,重国民党的新生活运动行前,小编都会clean一下,防止因为缓存出现的错误…这几个常常用,但是clean真正的乐趣小编还没读懂它.

本条漏洞非常多的发生原因一般是“XXX”这些文件(类库)就算引进了工程中,可是出于种种原因(常见于多个人支付,svn同步不僧不俗)导致“XXX”并未有被增添到project.pbxproj这几个文件中。

 

化解办法是点击工程,在targets分界面中找到Build
Phases,依照提示新闻“XXX”来判别缺乏什么文件,一般只要缺点和失误自定义的公文,XXX会是缺点和失误的类名,那么就在Complie
Sources中参与该文件。借使紧缺类库,则在Link Binary With
Libraries中加入该类库。

 

而地点难题是因为少在Link Binary With Libraries  中进入 libsqlite③.dylib
,增加后就能够编写翻译通过。

 

Xcode 7 缺少 *.dylib库的消除办法

Xcode7中 Link Binary With Libraries 没有 *.dylib库,只好找到相应的

澳门葡京 14

并发文件目录页面,连忙键 CMD+Shift+G
(Go to the

 问题6: “_OBJC_CLASS_$_MFMessageComposeViewController”, referenced from:

原因:

 

那是编写翻译器找不到符号定义,常常那表示有些framework未有参与项目中

 

缓和参考:

 

解读音讯,是因为找不到叫MFMessageComposeViewController的ObjC类。

 

搜寻MFMessageComposeViewController的音讯,得知其定义在MessageUI.framework中,将其插手到品种中就可以;

在网络拿到解决办法是:

 

在办事左侧导航栏Target–>Build Phases–>compile

添加.m文件

 

 

 

 

依赖比较能够瞥见 in FMDBTest,FMDBTest的Target里增多进去了了一些.m文件

 

澳门葡京 18

 

 

 

对于以上错误,依据网民解答笔者的敞亮是

 

我们在利用这么些第贰方类库文件时间接将其拖拽到工程之中,编写翻译的的时候Xcode也未尝活动引用,所以导致这么错误,那就要求我们手动增多。若是大家在工程中新建有个别文件就不会并发那样难点;

 

 

标题12:关于导入文本漏洞百出:too many errors emitted, stopping now [-ferror-l
