Qt应用程序抛出"dyld:找不到符号:__ cg_jpeg_resync_to_restart". [英] Qt application throws "dyld: Symbol not found: __cg_jpeg_resync_to_restart"

问题描述

我在OS X上遇到了众所周知的dyld问题.

I get well known dyld issue on OS X.

Qt.pro文件:

INCLUDEPATH += /usr/local/Cellar/libpng/1.6.23/include /usr/local/Cellar/jpeg/8d/include
LIBS += -L/usr/local/Cellar/libpng/1.6.23/lib -L/usr/local/Cellar/jpeg/8d/lib -ljpeg -lpng -ljpeg -lz

在运行时，我的应用程序抛出:

In runtime my application throws:

dyld:找不到符号:__cg_jpeg_resync_to_restart引用自: /System/Library/Frameworks/ImageIO.framework/Versions/A/Resources/libTIFF.dylib 预期位于:/usr/local/Cellar/jpeg/8d/lib/libjpeg.8.dylib中 /System/Library/Frameworks/ImageIO.framework/Versions/A/Resources/libTIFF.dylib

dyld: Symbol not found: __cg_jpeg_resync_to_restart Referenced from: /System/Library/Frameworks/ImageIO.framework/Versions/A/Resources/libTIFF.dylib Expected in: /usr/local/Cellar/jpeg/8d/lib/libjpeg.8.dylib in /System/Library/Frameworks/ImageIO.framework/Versions/A/Resources/libTIFF.dylib

我以前已经知道了这一点，并使用了 answer 对其进行了修复，但是现在又发生了，该建议不起作用.我该如何解决这个问题?

I already got this before and I fixed it using this answer, but now it occurs again and this advice not works. How can I solve this problem?

推荐答案

这只是QtCreator运行时问题. DanyAlejandro的答案(上述)部分正确.

This is only a QtCreator runtime issue. DanyAlejandro's answer (above) is partially correct.

1. 转到项目->运行->运行环境"(显示详细信息)
2. 我不建议您取消设置，而应该编辑 两者: DYLD_LIBRARY_PATH 和 DYLD_FRAMEWORK_PATH
3. 将/System/Library/Frameworks/ImageIO.framework/Resources:添加到两个路径的开头(用冒号分隔的字符串)
4. 再次构建项目-这将永久修复该问题

1. Go to Projects -> Run -> "Run Environment" (show Details)
2. I would not recommend Unset, rather you should edit Both: DYLD_LIBRARY_PATH and DYLD_FRAMEWORK_PATH
3. Add /System/Library/Frameworks/ImageIO.framework/Resources: to the beginning for both paths (colon delimited string)
4. Build project again - this will fix it for good
