pdftotext on Centos 6 64bit?

Question

I have a HostGator VPS server, and want to be able to run pdftotext, part of xpdf (http://www.foolabs.com/xpdf/download.html).

After testing this out on my Mac, it worked fine, so I went to installing it on my VPS server.

I followed the installation instructions and it all isntalled flawlessly:

Copy the executables (xpdf, pdftotext, etc.) to to /usr/local/bin.

Copy the man pages (*.1 and *.5) to /usr/local/man/man1 and /usr/local/man/man5.

Copy the sample-xpdfrc file to /usr/local/etc/xpdfrc

Then I tested it out:

root@*** [~]# pdftotext
pdftotext: /lib64/libc.so.6: version `GLIBC_2.11' not found (required by pdftotext)

So as you can see, it couldn't find /lib64/libc.so.6. /lib64/libc.so.6 is there, however, as shown by this:

I then contacted HostGator, where they told me that it will not work on my server, as it can't find /lib64/libc.so.6, and is therefor not available on Centos 6 64bit.

If this is indeed true, are there any alternatives to pdftotext that do a simple and fast conversion that would work on this server? Is it possible that the pdftotext can be complied for a different version, or that I installed it incorrectly with permissions?

CentOS ships pdftotext, so install that. Some other binary not made for CentOS or your particular CentOS version apparently does not work. — nos, Feb 12 '13 at 00:42
`poppler-utils` from base repo in centos 7 provides `/usr/bin/pdftotext` — buley, Jan 16 '15 at 08:16
I simply used "yum install xpdf", which worked fine for me, but it's required to install the EPEL repo first — grobmotoriker, Jun 27 '17 at 10:40
@buley I installed `poppler-utils`, but it has version 0.26.5 of `pdftotext`. How to get the newer version (version 4.0)? — LoMaPh, Nov 14 '18 at 01:02
`Xpdf` version that I downloaded from [Glyph & Cog](https://www.glyphandcog.com/opensource.html) gives the latest version (download [link](https://xpdfreader-dl.s3.amazonaws.com/xpdf-tools-linux-4.00.tar.gz)). — LoMaPh, Nov 14 '18 at 01:12

Neither of these commands will work:

yum install xpdf
yum install poppler-utils

xpdf will install poppler-utils anyway and this will result in this pdftotext

pdftotext version 0.26.5 Copyright 2005-2014 The Poppler Developers - http://poppler.freedesktop.org Copyright 1996-2011 Glyph & Cog, LLC

This is not the version you want. You want this one:

pdftotext version 4.03 [www.xpdfreader.com] Copyright 1996-2021 Glyph & Cog, LLC

This will require going to www.xpdfreader.com and then clicking on "Download". Use the latest versions from this page to set up the newer pdftotext command.

I actually compiled the sources myself:

cd /tmp
wget https://dl.xpdfreader.com/xpdf-4.03.tar.gz
tar -xf xpdf-4.03.tar.gz
cd xpdf-4.03
mkdir build
cmake -DCMAKE_BUILD_TYPE=Release

If successful you should see:

-- Configuring done -- Generating done -- Build files have been written to: /tmp/xpdf-4.03

Then just type:

make

It should end with:

[100%] Built target pdftotext

Then type

make install

Now when you type pdftotext you should see:

pdftotext version 4.03 [www.xpdfreader.com] Copyright 1996-2021 Glyph & Cog, LLC

Note: I wrote all my code for pdftotext version 4.03. Took me a while to realise 4.03 and 0.26 produce vastly different results.
