Question

其中mingw包含gcc 4.6.3名称 - i686-w64-mingw32.

在Windows上, Qt的.pro文件是一个hello world程序:

QT          += core gui
TEMPLATE    = app
TARGET      = ef

SOURCES     = ef.cpp
DEPENDPATH  += .

INCLUDEPATH += . 
INCLUDEPATH += c:/R-2.15.1/include
INCLUDEPATH += c:/R-2.15.1/library/Rcpp/include
INCLUDEPATH += c:/R-2.15.1/library/RInside/include

LIBS        += -L c:/R-2.15.1/bin/i386 -lR
LIBS        += -L c:/R-2.15.1/library/Rcpp/libs/i386 -lRcpp
LIBS        += -L c:/R-2.15.1/library/RInside/libs/i386 -lRInside 

该计划编制如下:

注意最后有一个警告.

系统路径如下:

Qt的路径:

请指出我错过的观点.

现在错误已更改为:

UPDATE

我刚删除了...之间的空间Wl, and -enable-std,上面的错误消失了:

Answer 1

曾经出现在这个合并请求存在的缺陷qmake.conf,其配置只要您使用的qmake的默认配置中使用的变量文件.

该选项-enable-stdcall-fixup需要以a为前缀,-Wl,以便正确解析,mingw32-g++因为在解析时-e...将被拆分-e ....此前缀仅表示"不解析以下内容,-e nable-stdcall-fixup而是-enable-stdcall-fixup".

该qmake.conf文件包含-Wl但错误的行,因此合并请求,说

领先的"-Wl"显然是意外分裂到了错误的界限.

补丁将-Wl一行向上移动.您可以在您的qmake.conf文件上手动执行此操作,该文件应位于Qt安装下mkspecs/win32-g++/qmake.conf.更改以下行:

QMAKE_LFLAGS    = -enable-stdcall-fixup -Wl,-enable-auto-import -Wl,-enable-runtime-pseudo-reloc
QMAKE_LFLAGS_EXCEPTIONS_ON = -mthreads -Wl

进入:

QMAKE_LFLAGS    = -Wl,-enable-stdcall-fixup -Wl,-enable-auto-import -Wl,-enable-runtime-pseudo-reloc
QMAKE_LFLAGS_EXCEPTIONS_ON = -mthreads

请注意,和之间应该没有空格.它应该作为一个单独的参数传递,以实现我们想要的.-Wl,-enable-stdcall-fixupg++
