i’m new at openlb and i was trying to generate an executable file for bstep2d programm by compiling the pre existing makefile through the command make.
i got a message telling me that there is nothing to be done for “all”
can you help me please figure out what is the problem?
Unfortunately, I cannot reproduce your problem. I downloaded the version 1.3-1 and unpacked it. Afterward, I used the ‘cd’ command to go to examples/laminar/bstep2d and then used ‘make’.
Now, bstep2d is compiling in precompiled mode. Could you maybe tell me more about the system and programs you are using? (OS, compiler + version) Additionally, did you change something before you tried to compile the example?
Usually, ‘there is nothing to be done for “all”’ indicates that there is already an executable and that this executable got created after the last source code changes. Is that maybe the case here?
As I can see in the second image that you posted, the first file is the executable file. Now in the terminal just type ./bstep2d and it will execute this file and you should get some output on your terminal.
