cd ~/build/qt
export MY_QT_SRC_DIR=~/repos/qt-everywhere-src-6.4.0
export MY_HOST_PATH=~/libs/QT6.4/MacOs
export MY_INSTALL_PATH=~/libs/QT6.4/iOs
export MY_MODE=release

${MY_QT_SRC_DIR}/configure -prefix $MY_INSTALL_PATH -qt-host-path $MY_HOST_PATH \

Building my app with QT6.4 on MacOs

Posted by | Mac OS X, QT |

I built QT6.4 and downloaded and installed QT Creator 8.0.1 and copied it to my MacOs machine:

scp qt-creator-opensource-mac-x86_64-8.0.1.dmg admin@192.168.0.112:/Users/admin/Downloads

QT Creator started successfully because I made .config folder writable while running my app with QT6.2. I added QT versions and kits:

Posted by | Mac OS X, QT |

I continued my experimentation in same SSH session where I built QT6.4 for MacOS with Ninja generator with the same QT sources location:

scp /mnt/d/dev.distrib/qt-everywhere-src-6.4.0.tar.xz admin@192.168.0.112:/Users/admin/repos
tar xf qt-everywhere-src-6.4.0.tar.xz
cd ~/build/qt
export MY_QT_SRC_DIR=~/repos/qt-everywhere-src-6.4.0

QT did not built with -debug-and-release option so I decided to build debug and release version separately with the following configurations:

On the same machine where I Built QT 6.2.2 for MacOS I opened SSH session and set the locale:

export LC_ALL=en_US.UTF-8  
export LANG=en_US.UTF-8

checked the locale has been set correctly:

How I fixed my contact form

Posted by | PHP, Ubuntu |

When I switched to PHP 7.4 I forgot to specify sendmail_path parameter in php.ini and my contact form stopped working. Today I found sendmail_path parameter in PHP 7.0:

cd /etc/php
find . -name "php.ini"

./7.0/fpm/php.ini
./7.0/cgi/php.ini
./7.0/cli/php.ini
./7.4/fpm/php.ini
./7.4/cli/php.ini

grep sendmail ./7.0/fpm/php.ini

sendmail_path = "/usr/sbin/sendmail -t -f *****@yandex.ru -i"
