wmake turns evil ???!!!
 

wmake has suddenly decided to randomly delete my source files when compiling. It happens during the wmakeLnInclude. Good thing I have backups! Here's the output:

dave@Bruce:~/OpenFOAM/dave-1.5-dev/src/PhD$ wmake libso

Every file that failed with ln (file exists) is deleted... mercilessly. (No name.H~ to save the day)

The files getting deleted I haven't touched for about a week, and have survived a wmake libso since then. All I did was add another couple of sources (none of the deleted files) to the library, and execute wmake libso. I frequently am adding sources to the library, the only difference I can think of is these ones are 2 directories deep, as opposed to one.

Any ideas?

Greetings David,

Uhm, are you by any chance putting the real files directly in lnInclude? Because lnInclude is a temporary folder, mainly for symbolic links to the headers, and meant for making it easier for wmake to build the desired binary!

Best regards,
Bruno

Good idea... but no. The problem even occurs after deleting lnInclude, and the .dep, all the Make/linux directories.

Hmm... that is strange... can you post the contents of the file Make/files? There should be a logical reason for wmake to go postal :rolleyes:

edit: it would also be good to know what the file Make/options has inside it!

You can use "wmakeLnInclude -f" to force an update of the linked files.


This could be that you reference multiSolver.C in a Make/files, but this file does not actually exist (any more).

multiSolver.C must be getting deleted before this point. Here is my Make/files:

buoyantPressure/buoyantPressureFvPatchScalarField.C
admScalar/admScalar.C
dummyControlDict/dummyControlDict.C
multiSolver/multiSolver.C
multiTimeInstant/multiTimeInstant.C
timeCluster/timeCluster.C
timeCluster/timeClusterList.C
// equation/equationMaster/equationMaster.C
// equation/equation/equation.C
// equation/equationOperation/equationOperation.C
// admScalar/admScalarList.C

LIB = $(FOAM_USER_LIBBIN)/libPhD

And here is my Make/options:

EXE_INC = \
-I$(LIB_SRC)/finiteVolume/lnInclude \
-Ituple2Lists

LIB_LIBS = \
-lfiniteVolume

Problem found
 

It was a file name collision.

PhD
|-timeCluster
|-Make
|-multiSolver
|-multiSolver_beforeChanges
|-multiSolver_bak
'-tuple2lists

I had copied the multiSolver directory to another name to archive some changes I was making. When wmakeLnInclude runs, it deletes all the duplicate source files in all directories, leaving only one copy... in my case, it left me the "multiSolver_beforeChanges" files.

Once I got rid of the archive directories, wmake started behaving again.

I'm thinking that's a pretty poor fail mode for a file name collision!

Hi Wyldcat,
During the compilation I have the following message:

wmakeLnInclude: linking include files to ./lnInclude
ln: failed to create symbolic link `./Lee.H': File exists
ln: failed to create symbolic link `./Lee.C': File exists

Is it wrong or it does not matter?

Quick answer: That seems to indicate that you placed real files inside the folder "lnInclude".
This "lnInclude" folder is meant to be used for symbolic links only, therefore if that message is being given, then you better double-check if those files are meant to be there on purpose or if they were accidentally moved into that folder.

Is this message showing up with any particular community contribution (namely, source code made available online) or is it code that you're creating yourself?
I ask this because if it's from something shared online, then we need to review the code with the respective authors, in order to fix this.

Hi wyldcat,
This is my source code. This situation appeared when:
1) firstly I compiled Lee.C and Lee.H files using wmake
2) then I deleted Lee files and compiled other anotherModel.C and andotherModel.H files
3) finally I came back to Lee model and deleted anotherModel files
after step 3 the message I mentioned in my post appeared, namely
wmakeLnInclude: linking include files to ./lnInclude
ln: failed to create symbolic link `./Lee.H': File exists
ln: failed to create symbolic link `./Lee.C': File exists

So I did not copy Lee files into lnInclude directory. How to remove this massage?
