Question

我正在尝试构建一个原始的Qt 4.8.3 tarball，并使用此命令配置构建：

./configure -opensource -xplatform win32-g++ -device-option CROSS_COMPILE=i686-w64-mingw32-

以下是（重新）运行make：

的结果

我正在使用最新的Debian 7（Wheezy）。

Answer 1

使用-no-iconv cc-ing 4.7时出现了同样的错误。

来到这个hack转到src / corelib / codecs / codecs.pri：

win32 {
        !contains(QT_CONFIG,iconv) {
                # no iconv, so we put all plugins in the library
                HEADERS += \
                        ../plugins/codecs/cn/qgb18030codec.h \
                        ../plugins/codecs/jp/qeucjpcodec.h \
                        ../plugins/codecs/jp/qjiscodec.h \
                        ../plugins/codecs/jp/qsjiscodec.h \ 
                        ../plugins/codecs/kr/qeuckrcodec.h \
                        ../plugins/codecs/tw/qbig5codec.h \
                        ../plugins/codecs/jp/qfontjpcodec.h
                SOURCES += \
                        ../plugins/codecs/cn/qgb18030codec.cpp \
                        ../plugins/codecs/jp/qjpunicode.cpp \
                        ../plugins/codecs/jp/qeucjpcodec.cpp \
                        ../plugins/codecs/jp/qjiscodec.cpp \
                        ../plugins/codecs/jp/qsjiscodec.cpp \ 
                        ../plugins/codecs/kr/qeuckrcodec.cpp \
                        ../plugins/codecs/tw/qbig5codec.cpp \
                        ../plugins/codecs/jp/qfontjpcodec.cpp
        }
}

还有其他错误和黑客，但看起来它们已经在4.8.3中消失了。

您缺少文本编解码器插件使用的libiconv库。有同样问题的人here。

Answer 3

为避免此错误：

In file included from main.cpp:42:0: dialog.h:65:5: error: ‘QSharedMemory’ does not name a type

看起来mxe使用./configure -nomake examples ...（另一个选项是vlc使用的，只做make sub-src而不是全局制作 - 尽管你不能使用make install这个方法因为它仍然试图构建示例）。看起来像qt中的一个bug给我...或者使用本地构建的qmake会有所帮助，没试过......

另见How do I configure Qt for cross-compilation from Linux to Windows target?

尝试在Debian上交叉编译Qt 4.8.3时为win32构建失败
