Installation fails on --chaco-- EDIT netcdf

[VictorEijkhout]

I thought I was letting cmake generate lots of output already, but I see no error in this.

cd /work2/00434/eijkhout/trilinos/build-15.1.0-stampede3-intel24-impi/packages/seacas/libraries/chaco && /opt/apps/cmake/3.28.1/bin/cmake -E cmake_symlink_library libchaco.so.15.1.0 libchaco.so.15 libchaco.so
[ 13%] Built target chaco
make[1]: *** [Makefile:169: all] Error 2

output attached.

I don't think this has anything to do with Chaco. From the log file:

make[3]: *** No rule to make target '/libpnetcdf.so', needed by 'packages/seacas/libraries/exodus/libexodus.so.15.1.0'.  Stop.

From the configure log:

-D TPL_ENABLE_Netcdf:BOOL=ON 
-D TPL_Netcdf_INCLUDE_DIRS:PATH= 
-D TPL_Netcdf_LIBRARY_DIRS:PATH= 
-D TPL_Netcdf_LIBRARIES=/libpnetcdf.so

Thanks for spotting that.

Eh, why didn't your cmake catch that? I've had it abort on me so many times for failing to find netcdf.

[cgcgcg]

I believe the library checks only run when TPL_Netcdf_LIBRARIES is not set directly with cmake -D. I would recommend to configure like so

-D TPL_ENABLE_Netcdf:BOOL=ON \
-D TPL_Netcdf_INCLUDE_DIRS:PATH=${WHEREVER_NETCDF_ROOT_IS}/include \ 
-D TPL_Netcdf_LIBRARY_DIRS:PATH=${WHEREVER_NETCDF_ROOT_IS}/lib \

Ok, I fixed the null variable.

Now I'm really confused. You're using libpnetcdf but also netcdf.h. The library that generates libpnetcdf only generates pnetcdf.h.

This relates to my question #12854

[cgcgcg]

I'm not the expert on *netcdf usage in Trilinos, but when I build using spack I usually build against

parallel-netcdf
[email protected]+parallel-netcdf

So I think you need both libraries, and there is an option in netcdf that enables (?) the dependency on pnetcdf.

For Trilinos I set:

-D TPL_ENABLE_Netcdf:BOOL=ON \
-D TPL_Netcdf_INCLUDE_DIRS:PATH=${WHEREVER_NETCDF_ROOT_IS}/include \ 
-D TPL_Netcdf_LIBRARY_DIRS:PATH=${WHEREVER_NETCDF_ROOT_IS}/lib \
-D TPL_ENABLE_Pnetcdf:BOOL=ON \
-D TPL_Pnetcdf_INCLUDE_DIRS:PATH=${WHEREVER_PNETCDF_ROOT_IS}/include \ 
-D TPL_Pnetcdf_LIBRARY_DIRS:PATH=${WHEREVER_PNETCDF_ROOT_IS}/lib \

[VictorEijkhout]

Ok, got it. So load sequential netcdf & (parallel) pnetcdf. With this my installation passes.

Better documentation of all these options would be a good idea.
