I cannot run cylinder2d example?!

[KlausB]

Hello,

I tried to run the cylinder2d example but the compilation seems to have failed.

I use Ubuntu 14.04 and have all prerequisites installed.

First, I ran make clean, make cleanbuild, make j4 in the maindirectory

Second, changed to the examples/cylinder2d directory and run again make clean, make cleanbuild, make j4

The terminal output shows a lot of “for the target compile nothing to do”

— Entering src/particles/forces (compile)
make[2]: Verzeichnis »/home/klaus/olb-1.0r0/src/particles/forces« wird betreten
make[2]: Für das Ziel »compile« ist nichts zu tun.
make[2]: Verzeichnis »/home/klaus/olb-1.0r0/src/particles/forces« wird verlassen
— Leaving src/particles/forces (compile)

---

There’s no binary so the compilation must have failed?!

How can I fix that?

Klaus

Dear Klaus,

just run “make” instead of “make j4” and it will work.

Hello Luis,

please just call make and if that still produces an error paste your command and the error message.

Luis Angel Aviles M@LuisAngel ~/olb-1.2r0/examples/cylinder2d
$ gcc ./cylinder2d.cpp
In file included from ./cylinder2d.cpp:41:0:
./olb2D.h:1:33: fatal error: boundary/boundary2D.h: No such file or directory

When I just write make it appear:

Luis Angel Aviles M@LuisAngel ~/olb-1.2r0/examples/cylinder2d
$ make
make: *** /home/: Is a directory. Stop.

I am inside of the folde cylinder2d..

Hello Luis,

Can you provide the output of pwd, cat Makefile and cat ~/olb-1.2r0/config.mk ?

Regards,
Markus
