How to apply poppler to qt4???

Hwanwoo

I use Qt4!!
sudo apt-get install libpoppler-qt5-dev ->sudo apt-get install libpoppler-qt4-dev
Sorry....
Several attempts were made.
At first, I tried to configure only, but it didn't work. I used apt and configure together in another example.

I've been trying all the ways on the internet for a few days.

@Hwanwoo Why do you try to compile poppler if you installed it already using apt?

Hwanwoo

@jsulm
I just tried to use it because there is a way to write both in the example.
If you can see only pdf in qt using poppler, it doesn't matter whether you use apt or compile.
I kept trying to compile, but it wasn't, so I just tried apt.

If I were you I would see if I could still find an existing downloadable sudo apt-get install libpoppler-qt4-dev somewhere on the web which can be installed on your distro. Unless you know that is not available.

I'm sorry, but I didn't understand what you meant.

sudo apt-get install libpoppler-qt4-dev

libpoppler-qt4-dev is already the newest version.
The following package was automatically installed and is no longer required:
  thunderbird-globalmenu
Use 'apt-get autoremove' to remove them.

When I apt-get, I get a message like this.
I don't know what to do anymore.

@Hwanwoo I already asked this question before, but you did not answer it: "Is it really libpoppler-qt4.so?"
So, again: what is the exact name of poppler-qt4 lib?

Also, I see that you are building for ARM. Are you, by any chance, doing cross-compilation?

@Hwanwoo
For my part, from reading what you had written I was not clear that you had succeeded in getting libpoppler-qt4-dev. It is not available for my distro. However, now I see that you have done so. In which case, like @jsulm I don't understand why you are not trying to get that working for you instead of deciding you need to build it.

In any case, please answer @jsulm's questions.

I'm sorry .
Previously, I didn't understand the question properly.
libpoppler-qt4.so is correct.
Is poppler-0.41.0.tar.xz correct for the poppler library name?
I found that I can only output PDF using configure on the desktop.
As you said, I had to do cross-compile for arm.
I should have looked up a lot and asked questions.
I'm sorry

This is not the name of Poppler library file but of the Poppler archive...

Hwanwoo

@jsulm
Is this a file?

./configure
make

This is the file created using the command above.
I can use pdf in qt in ubuntu environment, but not in target board.
So I am looking for arm cross compile.

Thzen you need to cross-compile that lib for your device.

Thank you for your help.
I looked up a lot and asked questions but thought my knowledge was lacking.
I want to browse more, try more and post the question again.
Thank you.
