QT+OpenCV出现错误:windres.exe: unknown option — W

QT整合OpenCV出现了下面的问题:

D:\Qt\Tools\mingw530_32\bin\windres.exe: unknown option — W
Usage: D:\Qt\Tools\mingw530_32\bin\windres.exe [option(s)] [input-file] [output-file]
The options are:
-i –input=<file> Name input file
-o –output=<file> Name output file
-J –input-format=<format> Specify input format
-O –output-format=<format> Specify output format
-F –target=<target> Specify COFF target
–preprocessor=<program> Program to use to preprocess rc file
–preprocessor-arg=<arg> Additional preprocessor argument
-I –include-dir=<dir> Include directory when preprocessing rc file
-D –define <sym>[=<val>] Define SYM when preprocessing rc file
-U –undefine <sym> Undefine SYM when preprocessing rc file
-v –verbose Verbose – tells you what it’s doing
-c –codepage=<codepage> Specify default codepage
-l –language=<val> Set language when reading rc file
–use-temp-file Use a temporary file instead of popen to read
the preprocessor output
–no-use-temp-file Use popen (default)
-r Ignored for compatibility with rc
@<file> Read options from <file>
-h –help Print this help message
-V –version Print version information
FORMAT is one of rc, res, or coff, and is deduced from the file name
extension if not specified. A single file name is an input file.
No input-file is stdin, default rc. No output-file is stdout, default rc.

Makefile:161: recipe for target ‘all’ failed
mingw32-make: *** [all] Error 2

解决办法如下:

If you have the following error : … windres.exe: unknown option — W …

try this : in cmake uncheck ENABLE_PRECOMPILED_HEADERS

If, in the file opencv/sources/modules/videoio/src/cap_dshow.cpp, you have the following error : ‘sprintf_instead_use_StringCbPrintfA_or_StringCchPrintfA’ was not declared in this scope …

try this :put the following line: #define NO_DSHOW_STRSAFE, before the line : #include “DShow.h”

在CMake生成makefile文件的时候ENABLE_PRECOMPILED_HEADERS去掉这个选项的 √ 就好了.
