Dear CMS,

I’m trying to run my UM vn13.5 suite u-dj442, which I upgraded from my colleague’ vn12.0 suite u-cy847 using ‘rose app-upgrade’. I then created vn13.5\_contrails\_Chen2012 branch mimicking vn12.0\_contrails\_Chen2012@119756.

So it is not surprising that it does not run from the first attempt. The first problem I encountered is the fcm\_build\_um failure. The error message is like this;

> [FAIL] LS\_CONTRAILS\_MOD.mod: bad or missing dependency (type=1.include)  
> [FAIL] required by: microphys\_ctl\_mod.o  
> [FAIL] required by: MICROPHYS\_CTL\_MOD.mod  
> [FAIL] required by: atmos\_physics1\_mod.o  
> [FAIL] required by: ATMOS\_PHYSICS1\_MOD.mod  
> [FAIL] required by: atm\_step\_4a\_mod.o  
> …etc.

I guess this happens because the compiling or linking process does not recognise ls\_contrails module, which was not present in the trunk version and I copied from the vn12.0 branch. So I think I have to add it somewhere but cannot figure out where and how.

Could you please help me? Thanks.  
Masaru

Hi Masaru,

I cannot see the new module in the branch history . Have you executed ‘fcm add’ for this and any new source files?

Hi Mohit,  
Thanks for your help. OK, so I should have done ‘fcm add’ before committing the branch. fcm\_build\_um is now finished successfully so I think the problem above has been resolved.
