Question

這mingw包含gcc 4.6.3，與名稱 - i686-w64-mingw32。

在的Windows，一個Qt的.pro文件w.r.t一個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 

程序編譯如下：

通知有在最後一個警告。

系統路徑如下：

Qt的路徑：

請你指出我錯過了點。

UPDATE：

UPDATE

我只是刪除了空間Wl, and -enable-std之間..和上述錯誤消失：

Answer 1

如this merge request看到有在qmake.conf文件，配置何時使用，變量中的錯誤你使用qmake的默認配置。

-enable-stdcall-fixup需要用-Wl,作爲前綴，以選項的話，被mingw32-g++正確解析，因爲解析時-e...將被分割爲-e ...。此前綴僅表示「不要將以下內容解析爲-e nable-stdcall-fixup，而是將其解析爲-enable-stdcall-fixup」。

的qmake.conf文件包含-Wl，但在錯誤的路線，因此合併請求，它說

領先「輪候冊，」顯然是不小心分裂到錯誤 線。

該修補程序將-Wl移動一行。您可以在qmake.conf文件中手動執行此操作，該文件應位於Qt安裝下的mkspecs/win32-g++/qmake.conf下。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 

進入這個：

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

注意，應該有-Wl,和-enable-stdcall-fixup之間沒有空格。它應該一個單一參數以達到我們想要的東西傳遞給g++。
