Solved 'qEnvironmentVariable' was not declared in this scope

[Seb Tur]

QString sysuser = qEnvironmentVariable("USER");
works on Opensuse
but i cannot build the same code on neither Ubuntu nor Win

I tried including QtGlobal but did not help

@Seb-Tur Which Qt version?
Please show the code.

@Seb-Tur said in 'qEnvironmentVariable' was not declared in this scope:

QString sysuser = qEnvironmentVariable("USER");

on Opensuse where it works qt 5.15

on Ubuntu fails on qt 5.9.5
on win fails on qt 5.5

code is very simple

void MainWindow::on_pushButton_clicked()
{
    QString sysuser = qEnvironmentVariable("USER");
    if (sysuser.isEmpty()) sysuser = qEnvironmentVariable("USERNAME");

    ui->pole->setText(sysuser);
}

Hi,

As stated in the documentation of qEnvironmentVariable it was added in Qt 5.10.

Solution : use qgetenv()
