Error on runnig the examples

[Javad Hashemi]

Hey Guys,

I installed Dealii-9.1.1 successfully. So, I wanted to run step-1 and followed the command lines based on README instruction. But, I have faced an error that you can see as follow:

root@Lenovo-PC:~/math/dealii-9.1.1/examples/step-1# cmake -DDEAL_II_DIR=/root/bin/dealii-9.1.1/ .

Javad,

I installed Dealii-9.1.1 successfully. So, I wanted to run step-1 and followed the command lines based on README instruction. But, I have faced an error that you can see as follow:

root@Lenovo-PC:~/math/dealii-9.1.1/examples/step-1# cmake -DDEAL_II_DIR=/root/bin/dealii-9.1.1/ .

[...]

root@Lenovo-PC:~/math/dealii-9.1.1/examples/step-1# make

Scanning dependencies of target step-1

[ 50%] Building CXX object CMakeFiles/step-1.dir/step-1.cc.o

make[2]: *** No rule to make target '/root/math/dealii-9.1.1/lib/libdeal_II.g.so.9.1.1', needed by 'step-1'.  Stop.

[...]

It looks like /root/math/dealii-9.1.1/lib/libdeal_II.g.so.9.1.1 is not accessible. Does this file exist? Is it readable?

Anyway, you should just install deal.II anew and make sure that the file exists in the installation directory.

Best,

Daniel

All files exist and accessible. Also, Cmake files are generated in the step-1 folder. But, I do not know why it does not work. I hope to get a suggestion for solving the problem.

Thanks, 

Javad

But it doesn't seem to be available when you run cmake. Can you show us
what you get when you do
ls -l /root/math/dealii-9.1.1/lib/
? I will note that in general, it's a bad idea to run things as root.
You should be running your programs as a regular user.

Best
W.

Dear Dr. Bangreth,

I really appreciate your email. I checked the lib folder and you can see the list of files as follow:

root@Lenovo-PC:~#  ls -l /root/math/dealii-9.1.1/lib/
total 0
drwxrwxrwx 1 root root 4096 Jul 28 02:11 cmake
drwxrwxrwx 1 root root 4096 Jul 28 02:12 pkgconfig

would you please help me to know the reason for the error?

Thanks.

Sincerely,

Javad

Apparently you did not install the library correct, there is no *.so-file in that folder. Maybe try to reinstall it?
