Dear Gregor,

I took Gregor advice and compiled "Fleur". As a result, I was able to compile "Fleur".
My solution is shown in the next line.

user@malive:~/Data/App/fleur$ sudo apt-get clean
user@malive:~/Data/App/fleur$ sudo apt-get install libxml2-dev
user@malive:~/Data/App/fleur$ find /usr/ -name libxml2*
/usr/include/libxml2
/usr/lib/x86_64-linux-gnu/libxml2.so.2
/usr/lib/x86_64-linux-gnu/libxml2.so.2.9.4
/usr/lib/x86_64-linux-gnu/libxml2.so
/usr/lib/x86_64-linux-gnu/libxml2.a
/usr/share/aclocal/libxml2.m4
/usr/share/lintian/overrides/libxml2
/usr/share/doc/libxml2-dev
/usr/share/doc/libxml2
user@malive:~/Data/App/fleur$ ./configure.sh >CompileResult.txt
user@malive:~/Data/App/fleur$ cd build ; make -j2
user@malive:~/Data/App/fleur/build$ ctest -I 1,35  >test.txt
 

I would like to thank you very much, Gregor. If you have any books or journals that explain the source code of Fleur, please introduce them to me. I am an undergraduate student majoring in Materials Science. I would like to be like Gregor, a first-class researcher and programmer.

Best Regards,

Dear Gregor,

Gregor, thanks for the reply.
The following line reports the result of entering the command.

$ find /usr/ -name libxml2*
> /usr/lib/x86_64-linux-gnu/libxml2.so.2
> /usr/lib/x86_64-linux-gnu/libxml2.so.2.9.4
> /usr/share/doc/libxml2
 

I am also eagerly awaiting your guidance on the next steps.
Thank you for giving of your time to me.

Best Regards,

Dear Gregor,

Thank you for your valuable advice.

The answer to your first question is: "The error message is the same whether the flag is present or not". I have attached a text file of the error message to this reply.

The answer to the second question is: "I compile on a small workstation".To describe the performance of this workstation, it has an "11th Generation Intel(R) Core(TM) i7-11800H @ 2.30 GHz" CPU and 32.0 GB of DRAM. We also built a virtual environment on the Windows OS and installed Debian 10.9 on that virtual environment to compile Fleur.

As a first aid measure I have decided to use Fleur with "Quantum Mobile". If I find a solution to this problem, I will post it in this thread.

I was delighted to receive Gregor's reply. Thank you very much for taking the time to share your valuable information with me.

Thanks,
Yuta.o
