Qt无法找到标准标头

Question

由于标准Qt包含文件/库丢失，编译失败，为什么？

我有设备的自定义工具链。我的编译失败的消息：包括来自/opt/STM/STLinux-2.3/devkit/sh4/target/usr/include/QtCore/QString:1:0， 从./menuitems/Item

在文件。 h：5, from /appmessages/AppMessageAgeLimit.h:4, from appmessages/AMessageDispatcher.cpp：2： /opt/STM/STLinux-2.3/devkit/sh4/target/usr/include/QtCore/qstring。小时：60：22：致命错误：字符串：没有这样的文件或目录

它猜测这个工具链配置错了，但我不知道如何解决它。以下是从“/opt/STM/STLinux-2.3/devkit/sh4/bin/sh4-linux-g++ -v”命令输出 - 可能会有用：

使用内置规格。 COLLECT_GCC =/opt/STM/STLinux-2.3/devkit/sh4/bin/sh4-linux-g ++ COLLECT_LTO_WRAPPER =/opt/STM/STLinux-2.3/devkit/sh4/libexec/gcc/sh4-linux/4.8.2/lto-wrapper 目标：sh4-linux 配置：/home/viatcheslavvgavrilov/qt/gcc-4.8.2/configure --target = sh4-linux --prefix =/opt/STM/STLinux-2.3/devkit/sh4 --exec-prefix =/opt/STM/STLinux-2.3/devkit/sh4 --bindir =/opt/STM/STLinux-2.3/devkit/sh4/bin --sbindir =/opt/STM/STLinux-2.3// dev/STM/STLinux-2.3/devkit/sh4/etc --datadir =/opt/STM/STLinux-2.3/devkit/sh4/share --includedir =/opt/STM/STLinux-2.3/devkit/sh4/include --libdir =/opt/STM/STLinux-2.3/devkit/sh4/lib --libexecdir =/opt/STM/STLinux-2.3/devkit/sh4/libexec --localstatedir =/opt/STM/STLinux-2.3/devkit/sh4/var --sharedstatedir =/opt/STM/STLinux-2.3/devkit/sh4/share --mandir =/opt/STM/STLinux-2.3/devkit/sh4/-infodir = /选择/ STM/STLinux-2.3/DEVK it/sh4/info --enable-checking = assert --program-prefix = sh4-linux- --with-local-prefix =/opt/STM/STLinux-2.3/devkit/sh4 --with-sysroot =/opt /STM/STLinux-2.3/devkit/sh4/target --enable-languages = c，C++ --enable-threads = posix --enable-nls --enable-c99 --enable-long-long --with-system -zlib --enable-shared --disable-libgomp --enable-multilib --with-multilib-list = m4，m4-nofpu --enable-symvers = gnu --with-gxx-include-dir =/target/usr/include目录/ C++/4.2.4 --enable -__ cxa_atexit 线程模型：POSIX gcc版本4.8.2 20131016（GCC）

Answer 1

The compilation is failing due to standard Qt include files/ library missing, why?

检查上qt.conf文件部分路径前缀通常有助于：

[Paths] 
Prefix=/some/path 

随着我的几个静态建Qt的味道，通常设置为一个：

[Paths] 
Prefix=/specific_prebuilt_qt/src/qtbase 

及默认前缀可能指向一个目录下最多可以是有效的情况下，但然后确保路径的Qt工具链是正确的。或者你打算使用Qt的文件夹bin？ qmake工具所在的文件夹。

[Paths] 
Prefix=.. 

在再次构建之前，确保在为项目执行前缀路径固定的qmake之后。
