[Trilinos-Users] amesos_amd_internal.h

[Jason Slemons]

Hello,

 

In packages/amesos/src/Amesos_Umfpack.cpp there is a call to
amd_defaults, which I have learned is not related to the chip company
but it means approximate minimum degree. I cannot find a definition for
amd_defaults though I have found one for AMD_defaults in
amesos_amd_internal.h. Should the instances of amd_defaults be replaced
with AMD_defaults?

 

An example of the error I get when compiling a program that calls
amd_defis:

/ptmp/slemons/chrislib/libamesos.a(Amesos_Umfpack.o): In function
`Amesos_Umfpac
k::Amesos_Umfpack(Epetra_LinearProblem const&)':

Amesos_Umfpack.cpp:(.text+0x3fe): undefined reference to `amd_defaults'

 

Im also getting something that seems related in another library.

/ptmp/slemons/christof.trilinos-9.0.3/gccBUILD/lib/libumfpack.a(umf_i_fr
ee.o): In function `umf_i_free':

umf_free.c:(.text+0xb): undefined reference to `amd_free'

Jason,

 

There is no manual that I am aware of that describes this kind of thing.
You will want to delete CPP from DIST_SUBDIRS and SUBDIRS.  DIST_SUBDIRS
probably isn't necessary, unless it happens to be defined as $(SUBDIRS),
but it doesn't hurt to remove it there too in your case.

 

If you didn't already know, we will be scrapping the whole build system
with our next release, which is due out by Oct 1.

 

Jim

Thanks Jim, 

 

When I first read your note about editing the makefile I was scared to
touch it but I think I see what you mean and now I think the
modification (deleting CPP under DIST_SUBDIRS) should do it. The more I
learn about these makefiles the better off ill be. There isn't like a
secret developers manual that describes the make process in more detail
is there? 

 

Thanks,

Jason,

 

Unfortunately there is not a very reliable way to reconfigure a subset
of Trilinos.  If you really want to avoid reconfiguring, you could edit
the Makefile directly to exclude the broken directories from SUBDIRS in
the directory above the one you want to skip.  I would also add the
option Karen suggested to your list of configure arguments so that if
you configure again, you don't end up overwriting the SUBDIRS hack.

 

In general, I don't advise reconfiguring Trilinos without blowing away
your biuld tree and starting from scratch.  Autoconf just don't handle
reconfiguring well in general.

 

When we move to CMake with the next release, your ability to reconfigure
will improve in many circumstances (although it will not be possible to
configure individual packages from the package level at all).

 

Jim

Hey Jim, 

 

I noticed that the zoltan examples in CPP do not build correctly. I
emailed zoltan users and Karen Devine wrote me back saying she and the
zoltan team were working on it. Is there some way to tell 'make tests'
not to build the c++ examples when I type 'make tests' from my build
directory? I was told that  re-running configure with
--disable-zoltan-cppdriver added will make this happen, but I wonder if
there is some way to re run configure just on zoltan, and not for every
package built. When I went to the zoltan
directory(BUILD/packages/zoltan) and typed in my configure script it
started going through all the packages.
