HOW TO BUILD QT5
================


 Synopsis
 ========

   System requirements
   ------------------

    - Perl 5.8 or later
    - Python 2.7 or later
    - C++ compiler supporting the C++11 standard
    ...

执行configure

1
./configure -prefix $PWD/build -opensource -nomake tests -nomake examples

参数:

-prefix $PWD/build生成路径

-opensource开源用户

-nomake tests -nomake examples跳过tests和examples

出现ERROR:提示时需要根据说明安装缺少的包或者配置相应的环境变量

出错后需要rm -rf config.cache删除config.cache后重新执行./configure -prefix $PWD/build -opensource -nomake tests -nomake examples

可能遇到bash和perl权限不够的问题。修改/usr/bin/目录下的bash、sh、dash和perl的权限为777。

configure执行成功后显示如下内容

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into '/home/flame/qt-everywhere-src-5.12.8/build'.

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.

编译

1
make
