Cannot open QT linguist on Linux (Ubuntu)

[kenneth1]

I have installed Qt Creator 4.9.0, Based on Qt 5.12.2 on Linux (Ubuntu)

and I want to run linguist

I successfully used Linguist on Windows where I performed these three steps:

1. In QTCreator, click Tools\External\Linguist\Update Translations (lupdate)

2. Open linguist and enter the foreign text.

3. In QTCreator, click Tools\External\Linguist\Release Translations (lrelease)

On Linux, step 2 does not work because the file /opt/Qt/5.12.2/gcc_64/bin\linguist will not open and so I cannot enter foreign text.

File properties for linguist show

    type = executable (application/x-executable)

    execute = allow executing file as program

How can this file be run?

What happens when you run /opt/Qt/5.12.2/gcc_64/bin/linguist from terminal? Any error messages?

If you get errors about missing Qt libraries, then you need to run this:

export LD_LIBRARY_PATH= /opt/Qt/5.12.2/gcc_64/lib
 /opt/Qt/5.12.2/gcc_64/bin/linguist

You can put that export line in your .profile file so it will always be defined. Also, don't install Qt to /opt if you don't have to. Installing into user directory is fine.

Alternatively: install linguist from your Linux distribution. It's boths forward- and backward-compatible so it does not matter which Linguist version you run.

Under Ubuntu Linux, the simplest is to install linguist from the Ubuntu package repositories:

sudo apt install qttools5-dev-tools

For reference, in Qt4 the equivalent command was:

sudo apt install qt4-dev-tools
