前言
在deepin 64 系统编译Qt(执行make)时报错:

查询得知是编译器参数设置不对,应该加上:-std=gnu++98
参数

解决办法:
1、 找出当前编译的版本,其目的是定位源码中 mkspecs/… 下面的编译选项设置目录
执行./configure 后,在输出文本中搜索mkspecs
或者Build type:
,可以找到对应的文件夹
或者:
2、打开mkspecs/对应版本/qmake.conf
修改其中的QMAKE_CXXFLAGS
为:QMAKE_CXXFLAGS = $$QMAKE_CFLAGS -std=gnu++98
如果该文件中不存在QMAKE_CXXFLAGS
参数,则在该文件包含的头文件中查找。
例如:
该文件不存在QMAKE_CXXFLAGS
参数,则打开 ../common/linux.conf
、../common/gcc-base-unix.conf
、../common/g++-unix.conf
这三个文件。如果没有找到还需要递归的打开着三个文件中包含的文件。
在../common/gcc-base.conf
(包含在文件../common/gcc-base-unix.conf
中)文件中找到,并修改为如下所示。
在../common/g++-base.conf
(包含在文件../common/g++-unix.conf
中)文件中找到,并修改为如下所示。
然后执行:
To reconfigure, run ‘make confclean’ and ‘configure’.
make confclean
./configure (...)
make -j4
make install
编译安装完成。
