Does QT for X11 include QT Creator?

cpatterson

HI, I am new to QT, and I installed QT 5.1.0 for X11 (qt-everywhere-opensource-src-5.0.2.tar.gz) on my rhel 6 machine. This includes Designer, Assistant, etc., and I assumed it also included Creator but I can't find it anywhere. Do I need to download QT Creator separately? If so, does the QT 5.1.0 that I just installed have all the necessary libraries for QT Creator? Thanks!

sierdzio

No, source packages for Qt contain Qt libraries only. Qt Creator is a separate product (but is shipped with prebuilt Qt SDKs). And yes, the libraries you have are enough for Creator. Just check out it's README for instructions.

And please, note that it is Qt, not QT. QT is usually associated with Apple's QuickTime, and we don't want that association do we?

Hell no :) But I grew tired of seeing that being pointed out everywhere, so I stopped paying attention when people get it "wrong". It is not a big mistake anyway. And Google searches in lowercase only, so for them Qt and QT are equal.

cpatterson

Sierdzio, thanks for the help. I downloaded Creator and opened the README file for installation instructions. But the qmake -r command wouldn't work. There isn't a Makefile at the top level. I found a Makefile.linux in one of the subdirectories. Should I use that?

Hi,

Did you download the sources or the pre-built version of QtCreator ?

cpatterson

I downloaded Qt Creator source code tar.gz (which is "qt-creator-2.8.0-src.tar.gz").

andre

I'd say: why don't you try and see if QtCreator isn't already provided as a package by your distro, or perhaps even an alternate repository for your distribution?

sierdzio

It should work, then. This is what I usually do to build QtC:
@
cd /my/extracted/qtcreator
mkdir build
cd build
qmake ../qtcreator.pro
make -j9
@

That's it. So far it has worked every time, also when building with QBS enabled.

cpatterson

Thank you. I followed the instructions, and I received these errors after the qmake:

SGaist

What does your qmake --version return ?

cpatterson

Qmake version: 1.07a (Qt 3.3.8b)

SGaist

3.3.8 ? It's a really really old qmake... What system are you running that uses such an outdated Qt ?

cpatterson

rehl 6

SGaist

Like the error message says, you have to first install at least Qt 4.8

cpatterson

I downloaded the Qt source code tar.gz (which is “qt-everywhere-opensource-src-5.1.0.tar.gz”) and used the instructions from http://qt-project.org/doc/qt-5.0/qtdoc/install-x11.html to make and install. I also downloaded Qt Creator source code tar.gz (which is “qt-creator-2.8.0-src.tar.gz”), looked at the README file for installation instructions, but the qmake didn’t work. So, evidently the system isn't recognizing the newer version of Qt. How can I fix that?

SGaist

You can simply use the full path to your Qt 5.1 qmake.

Building & installing Qt from sources won't overwrite your system Qt install (that would wreak havoc)

cpatterson

Okay, thanks! That worked. After the qmake worked, I continued to follow sierdzio's instructions (shown below), and performed the "make -j9".

cd /my/extracted/qtcreator
mkdir build
cd build
qmake ../qtcreator.pro
make -j9

After the "make -j9", it appeared to make until I received these errors:

make[3]: Leaving directory /home/cpatterson/Downloads/qt-creator-2.8.0-src/build/src/libs/ssh' make[2]: Leaving directory /home/cpatterson/Downloads/qt-creator-2.8.0-src/build/src/libs'

make[1]: Leaving directory `/home/cpatterson/Downloads/qt-creator-2.8.0-src/build/src'
make: *** [sub-src-make_first-ordered] Error 2

Do you know what's wrong with this? I'm sorry to know such a small amount, but I'm trying to learn. Thanks!

SGaist

You'll have to post more lines, where the error currently happens

cpatterson

Is this what you mean? These are the last lines in the make.
