Qt5.11交叉编译错误：Qmake spec does not set MAKEFILE_GENERATOR

devin

在Debian9.4虚拟机上交叉编译Qt5.11.0源文件，准备移植到arm上。出现了以下错误：Project ERROR: Qmake spec does not set MAKEFILE_GENERATOR.

具体操作过程如下：1.已经装好了arm-linux-gnueabihf-toolchain

1. devin@debian-PC:/usr/bin$ ls arm-linux-gnueabihf*
   
2. arm-linux-gnueabihf-addr2line     arm-linux-gnueabihf-gcov-dump-6
   
3. arm-linux-gnueabihf-ar            arm-linux-gnueabihf-gcov-tool-6
   
4. arm-linux-gnueabihf-as            arm-linux-gnueabihf-gprof
   
5. arm-linux-gnueabihf-c++filt       arm-linux-gnueabihf-ld
   
6. arm-linux-gnueabihf-cpp-6         arm-linux-gnueabihf-ld.bfd
   
7. arm-linux-gnueabihf-dwp           arm-linux-gnueabihf-ld.gold
   
8. arm-linux-gnueabihf-elfedit       arm-linux-gnueabihf-nm
   
9. arm-linux-gnueabihf-g++           arm-linux-gnueabihf-objcopy
   
10. arm-linux-gnueabihf-g++-6         arm-linux-gnueabihf-objdump
    
11. arm-linux-gnueabihf-gcc           arm-linux-gnueabihf-pkg-config
    
12. arm-linux-gnueabihf-gcc-6         arm-linux-gnueabihf-ranlib
    
13. arm-linux-gnueabihf-gcc-ar-6      arm-linux-gnueabihf-readelf
    
14. arm-linux-gnueabihf-gcc-nm-6      arm-linux-gnueabihf-size
    
15. arm-linux-gnueabihf-gcc-ranlib-6  arm-linux-gnueabihf-strings
    
16. arm-linux-gnueabihf-gcov-6        arm-linux-gnueabihf-strip

复制代码

2.已经装好了以下必要的库

1. libfreetype6-dev        
   
2. libfontconfig1-dev
   
3. libxext-dev
   
4. libxfixes-dev
   
5. libxrender-dev
   
6. libxi-dev
   
7. libxkbcommon-dev
   
8. libxcb1-dev
   
9. libx11-xcb-dev
   
10. libxcb-glx0-dev
    
11. libxcb-keysyms1-dev
    
12. libxcb-image0-dev
    
13. libxcb-shm0-dev
    
14. libxcb-icccm4-dev
    
15. libxcb-sync0-dev
    
16. libxcb-xfixes0-dev
    
17. libxcb-shape0-dev
    
18. libxcb-randr0-dev
    
19. libxcb-render-util0-dev

复制代码

3.修改qmake.conf文件：

1. devin@debian-PC:~/qt-src/qt-everywhere-src-5.11.0/qtbase/mkspecs/linux-arm-gnueabihf-g++$ more qmake.conf
   
2. #
   
3. # qmake configuration for building with arm-linux-gnueabihf-g++
   
4. #
   
5. 
   
6. MAKEFILE_GENERATOR      = UNIX
   
7. TEMPLATE                = app
   
8. CONFIG                  += qt warn_on release incremental link_prl gdb_dwarf_index
   
9. QT                      += core gui
   
10. QMAKE_INCREMENTAL_STYLE = sublib
    
11. 
    
12. include(../common/linux.conf)
    
13. include(../common/gcc-base-unix.conf)
    
14. include(../common/g++-unix.conf)
    
15. 
    
16. # modifications to g++.conf
    
17. QMAKE_CC                = arm-linux-gnueabihf-gcc
    
18. QMAKE_CXX               = arm-linux-gnueabihf-g++
    
19. QMAKE_LINK              = arm-linux-gnueabihf-g++
    
20. QMAKE_LINK_SHLIB        = arm-linux-gnueabihf-g++
    
21. 
    
22. # modifications to linux.conf
    
23. QMAKE_AR                = arm-linux-gnueabihf-ar cqs
    
24. QMAKE_OBJCOPY           = arm-linux-gnueabihf-objcopy
    
25. QMAKE_NM                = arm-linux-gnueabihf-nm -P
    
26. QMAKE_STRIP             = arm-linux-gnueabihf-strip
    
27. 
    
28. load(qt_config)

复制代码

4.在~/qt-src/qt-everywhere-src-5.11.0中新建脚本文件 cfg_arm.sh

1. devin@debian-PC:~/qt-src/qt-everywhere-src-5.11.0$ more cfg_arm.sh
   
2. #!/bin/sh
   
3. 
   
4. ./configure  \
   
5. -v  \
   
6. -prefix /opt/qt5.11.0-armhf  \
   
7. -opensource  \
   
8. -confirm-license  \
   
9. -release  \
   
10. -xplatform linux-arm-gnueabihf-g++ \
    
11. -make libs  \
    
12. -qt-libjpeg \
    
13. -qt-libpng \
    
14. -qt-zlib \
    
15. -skip qtpurchasing  \
    
16. -nomake examples  \
    
17. -nomake tests  \
    
18. -make tools

复制代码

5.运行cfg_arm后出现以下错误：

   Project ERROR: Qmake spec does not set MAKEFILE_GENERATOR.

1. root@debian-PC:/home/devin/qt-src/qt-everywhere-src-5.11.0# ./cfg_arm.sh
   
2. + cd qtbase
   
3. + /home/devin/qt-src/qt-everywhere-src-5.11.0/qtbase/configure -top-level -v -prefix /opt/qt5.11.0-armhf -opensource -confirm-license -release -xplatform linux-arm-gnueabihf-g++ -make libs -qt-libjpeg -qt-libpng -qt-zlib -skip qtpurchasing -nomake examples -nomake tests -make tools
