Compiling QTDIR environment variable must be set

[Mint2be]

I get this when compiling: configure: error: QTDIR environment variable must be set

How do I set it? Can't find anything concrete online. I've gotten this far in a compile, but not I'm stuck.

TIA

Compiling what

The README might mention that you have to set that in the environment with

Code: Select all

export QTDIR="/path/to/somwhere"

[Mint2be]

Ok, I got past that, but now I have another error. The read me says: If it is not found on your system, please use
./configure --with-lrelease-bin=LRELEASE_BINARY_WITH_PATH.

What does that mean?

Newbie here

I've never encountered --with-lrelease-bin= so I couldn't say for sure. However it appears to to be similar to --with-local-prefix=/tools which tells gcc to search for locally installed include files. The default location is / usr/ local so it's forcing an override of the default setting.

So it seems that LRELEASE_BINARY_WITH_PATH should be set just like QTDIR

Here is the full text of what the readme says:
- qmake is searched in $QTDIR/bin, /usr/bin, /usr/local/bin,
/usr/lib/qt3/bin and in directories in $PATH. If you have
qmake installed in other directory, use:
./configure --with-qmake=QMAKE_BINARY_WITH_PATH

- QT comes with lrelease binary which is used for
localization data files translation. This binary is
searched in $QTDIR/bin, /usr/bin, /usr/local/bin,
/usr/lib/qt3/bin and in directories in $PATH.
If it is not found on your system, please use
./configure --with-lrelease-bin=LRELEASE_BINARY_WITH_PATH

In Synaptic there is qmake4 and 5, but no qmake 3, which is what it says it can't find. I've spent way too much time on this, but I really want to accomplish it for my own knowledge.

localization data files translation. This binary is
searched in $QTDIR/bin, /usr/bin

Code: Select all

bill@qiana /media/linuxshared $ whereis lrelease
lrelease: /usr/bin/lrelease /usr/bin/X11/lrelease

So it's in the search path /usr/bin

What did you set QTDIR to

[Mint2be]

I guess I don't understand what I am doing. What is the read me instructing me to do? What does the code you posted mean? Sorry, but I'm new to all this compiling.

According to the message /usr/bin is one of the places where it searches for the binary lrelease.

So when I ask

Code: Select all

whereis lrelease

it comes back with /usr/bin/lrelease

So it's certainly there, at least on my system - what about yours

[Mint2be]

whereis lrelease
lrelease: /usr/bin/lrelease /usr/bin/X11/lrelease

[WharfRat]

Well a little more digging and lrelease is a symlink /usr/bin/lrelease -> qtchooser

When I try

Code: Select all

lrelease -list-versions

it doesn't work, but

but this works

Code: Select all

bill@qiana ~/script $ qtchooser -list-versions
4
5
default
qt4-i386-linux-gnu
qt4-x86_64-linux-gnu
qt4
qt5-x86_64-linux-gnu
qt5

I really don't know anything about this app, but maybe try

Code: Select all

export LRELEASE_BINARY_WITH_PATH=$(which qtchooser)

I don't see anything mentioning version 3 though

Like your profile name.

Is the program under your home folder but looking only in root folders for it?

[Mint2be]

Now I'm back to the original QTDIR environment variable must be set error. I think it's no longer worth trying to compile this

Why are you keeping what you're attempting to compile a secret

[Mint2be]

It is PDFedit, which I don't really even need because I have an addon for Firefox that works well, but once I got started I didn't want to give up

I actually mentioned that it was PDFedit in another post related to this one about how to install a program from a folder.

Is this package installed

libqt4-qt3support - Qt 3 compatibility library for Qt 4

It's not on mine

Yep. It's installed already.

This app seems to suffering from outdatedness. I've seen references pertaining to installing qt3-dev-tools dated December 2005.

It's just not going to fly

I agree. At least it was good practice
