Hi Olivier,

Hi Olivier,
I'm just forwarding this to Debian Mentors list to get a wider audience.
I'd prefer a fix over simply removing the test ...

            // operator const std::string& () const { return
line_string() ; }
do the job and test pass
but I would prefer a c++ friend to acknowledge this.... It works but I
do not if there are side effects....

Any news about this?

Kind regards

Andreas.

Hi Olivier, any solution?

libgtextutils 0.7-6 is marked for autoremoval from testing on 2019-10-25

Maybe this isn't worth our time. libgtextutils is only needed for fastx
toolkit.

Both are officially abandoned by upstream since 2017.

From the fastx toolkit readme:

https://github.com/agordon/fastx_toolkit/blob/master/README#L7

* FASTX TOOLKIT is unmaintained software. *
* No new features have been added since 2010. *
* *
* There are many better alternatives for low-level FASTQ/FASTA *
* manipulation. Use at your own risk.
