QT5.15.2编译安装出现是的错误

[quan-wei-jun]

The first step is to extract the file

Sudo tar - xvf qt everywhere src-5.15.2. tar

Step 2: Switch to the directory file

Cd qt everywhere src-5.15.2

Step 3: I specify the platform and do not specify a path/ Configure automatic assignment

./configure

Result:

I'll go find gcc version 4.2 and enter gcc -- version in the user's root directory, but it shows 5.4.0

This is a problem that I can't figure out. How to find the issue with gcc version 4.2.1 and remove it, or how to connect it to gcc version on the command line

[sierdzio]

@quan-wei-jun your compiler is too old and does not support C++11 or C++14. See https://gcc.gnu.org/projects/cxx-status.html

How to find the issue with gcc version 4.2.1 and remove it

Depends on what operating system are you using - but the easiest way would typically be to use your package manager to uninstall old GCC version.

If you can't do that, use CC and CXX env variables to point to your newer GCC.

@sierdzio
My computer comes with gcc version:
gcc --version
gcc (Ubuntu/Linaro 5.4.0-6kord1~16.04.12) 5.4.0 20160609

whereis gcc：
gcc: /usr/bin/gcc /usr/lib/gcc /usr/share/man/man1/gcc.1.gz

But it uses 4.2.1

How can I modify it to the computer's built-in gcc

[sierdzio]

@quan-wei-jun Are you running configure on the same computer where you check GCC? An arm64 machine?

Qt takes compilers from normal, expected OS paths so it really should not happen that you get different result.

[quan-wei-jun]

@sierdzio said in QT5.15.2编译安装出现是的错误:

@quan-wei-jun您是否在检查 GCC 的同一台计算机上运行配置？一台arm64机器？

It is the same machine that operates, but there is no Stöð 2 machine

[quan-wei-jun]

@sierdzio This makes me very distressed. After configuration, I am indeed using 4.2.1, but the gcc -- version I entered on the command line is 5.4.0. I guarantee that this operation is performed on the same machine. I want him to use gcc 5.4.0. How should I configure it

[JoeCFD]

@quan-wei-jun in an editor open your Makefile generated from configuration and do the following:
set(replace)
//if /usr/bin/gcc --version is 5.4.0
CC=/usr/bin/gcc
CXX=/usr/bin/g++

//if /usr/lib/gcc --version is 5.4.0
CC=/usr/lib/gcc
CXX=/usr/lib/g++

you will be good to go.

What do you mean/ Modify the makefile after configuring

CC=/usr/lib/gcc
