Qt-creator示例无法为iphonesimulator构建 [英] Qt-creator examples fail to build for iphonesimulator

问题描述

我已经使用Xcode 8在El Capitan上成功安装了Qt 5.7.0和Qt-creator 4.1.0.

I've successfully installed Qt 5.7.0 and Qt-creator 4.1.0 on El Capitan with Xcode 8.

我修复了来自qt的 xcode sdk版本错误，现在我尝试构建其中一个示例适用于iphonesimulator.他们都不工作.它们全部失败，并显示以下错误消息:

I fixed the xcode sdk-version errors from qt, and now I'm trying to build one of the examples for iphonesimulator. None of them work. All of them fail with error message of type:

The following build commands failed:
CopyPNGFile Debug-iphonesimulator/2dpainting.app/[e-mail] 2dpainting.xcodeproj/[e-mail]

我可以确认Debug-iphonesimulator/2dpainting.app目录没有png文件，它实际上位于qt安装目录中的某个位置.将png复制到源文件夹无济于事，因为在运行"make"时该文件夹将被覆盖.

I can confirm that directory Debug-iphonesimulator/2dpainting.app does not have the png-file, it's actually located somewhere within the qt installation directories. Copying the png to the source folder does not help as the folder gets overwritten upon running 'make'.

任何建议将不胜感激.

生成工具包会警告以下问题:"Qt版本不支持设备类型".设备类型为"iOS模拟器".

The build kit warns about the following issue: "Device type is not supported by the Qt version". Device type is 'iOS simulator'.

推荐答案

将Xcode更新到8.0版后，我遇到了同样的问题.

I had the same problem after I had updated my Xcode to version 8.0.

我的第一个错误是"项目错误:Xcode设置不正确.您可能需要通过运行/usr/bin/xcodebuild来确认许可协议."为了解决这个问题，我创建了一个符号链接:

My first error was "Project ERROR: Xcode not set up properly. You may need to confirm the license agreement by running /usr/bin/xcodebuild." To solve this problem, I created a symbolic link:

cd /Applications/Xcode.app/Contents/Developer/usr/bin/
sudo ln -s xcodebuild xcrun

然后我收到错误消息" Project ERROR:当前的iphonesimulator SDK版本(10.0)太旧.请升级Xcode."我在文件 QT_DIR/5.7/ios/mkspecs/macx-ios-clang/features/sdk.prf

Then I got error "Project ERROR: Current iphonesimulator SDK version (10.0) is too old. Please upgrade Xcode." I commented two strings out in file QT_DIR/5.7/ios/mkspecs/macx-ios-clang/features/sdk.prf

lessThan(QMAKE_MAC_SDK_VERSION, "8.0"): \
    error("Current $$QMAKE_MAC_SDK SDK version ($$QMAKE_MAC_SDK_VERSION) is too old. Please upgrade Xcode.")

然后我得到了关于模拟器的错误.Qt找不到它.我从以下位置替换了文件 QT_DIR/5.7/ios/mkspecs/macx-ios-clang/xcodebuild.mk 中的代码行:

Then I got error about emulator. Qt could not find it. I replaced line of code in file QT_DIR/5.7/ios/mkspecs/macx-ios-clang/xcodebuild.mk from:

IPHONESIMULATOR_GENERIC_DESTINATION := "id=$(shell xcrun simctl list devices | grep -E 'iPhone|iPad' | grep -v unavailable | perl -lne 'print $$1 if /((.*?))/' | tail -n 1)"

收件人:

IPHONESIMULATOR_GENERIC_DESTINATION := "id=$(shell xcrun simctl list devices | grep -E 'iPhone|iPad' | grep -v unavailable | awk 'match ($$0, /\(([A-F0-9\-]*\))/ ) { print substr ($$0, RSTART+1, RLENGTH-2) }' | tail -n 1)"

最后所有这些我都得到了错误"以下构建命令失败:CopyPNGFile Debug-iphonesimulator/Test01.app/[e-mail] Test01.xcodeproj/[e-mail] "

And finally afer all of it I got error "The following build commands failed: CopyPNGFile Debug-iphonesimulator/Test01.app/[e-mail] Test01.xcodeproj/[e-mail]"

发生此错误是因为系统有两个文件 xcrun.脚本/Applications/Xcode.app/Contents/Developer/usr/bin/copypng开始一个，它是一个符号链接.然后我在此脚本中更改了路径来自:

This error occurred due to the fact that the system has two file xcrun. And script /Applications/Xcode.app/Contents/Developer/usr/bin/copypng starts one, which is a symbolic link. Then I changed path in this script from:

my $PNGCRUSH = `xcrun -f pngcrush`;

收件人:

my $PNGCRUSH = `/usr/bin/xcrun -f pngcrush`;

然后我终于没有错误地构建了项目，并在Xcode中打开了它.

And then I finally had built the project without errors and opened it in Xcode.
