Qt無法找到標準標頭

Question

由於標準Qt包含文件/庫丟失，編譯失敗，爲什麼？

我有設備的自定義工具鏈。我的編譯失敗的消息：包括來自/opt/STM/STLinux-2.3/devkit/sh4/target/usr/include/QtCore/QString:1:0， 從./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。小時：60：22：致命錯誤：字符串：沒有這樣的文件或目錄

它猜測這個工具鏈配置錯了，但我不知道如何解決它。以下是從「/opt/STM/STLinux-2.3/devkit/sh4/bin/sh4-linux-g++ -v」命令輸出 - 可能會有用：

使用內置規格。 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 目標：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 = /選擇/ 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目錄/ C++/4.2.4 --enable -__ cxa_atexit 線程模型：POSIX gcc版本4.8.2 20131016（GCC）

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

檢查上qt.conf文件部分路徑前綴通常有助於：

[Paths] 
Prefix=/some/path 

隨着我的幾個靜態建Qt的味道，通常設置爲一個：

[Paths] 
Prefix=/specific_prebuilt_qt/src/qtbase 

及默認前綴可能指向一個目錄下最多可以是有效的情況下，但然後確保路徑的Qt工具鏈是正確的。或者你打算使用Qt的文件夾bin？ qmake工具所在的文件夾。

[Paths] 
Prefix=.. 

在再次構建之前，確保在爲項目執行前綴路徑固定的qmake之後。
