Building 64-bit SL16j Release on SDCC

[plexoos]

The following assumes the default environment is initialized by sourcing:

source /afs/rhic.bnl.gov/rhstar/group/star_cshrc.csh

Switch to your local star-sw directory and check out the SL16j_embed_64b branch:

cd star-sw
git checkout SL16j_embed_64b

Without changing directories, set the environment variables required by cons:

setenv NODEBUG yes
setup 64b
setenv STAR $PWD
setenv STAR_LIB $STAR/.${STAR_HOST_SYS}/LIB
setenv STAR_BIN $STAR/.${STAR_HOST_SYS}/BIN

Then build the code:

cons +StarVMC/Geometry
cons

@genevb Let me know if this is what you are looking for. The branch contains a few patches needed for cons to work in the Spack environments.

Hi, Dmitri Thanks for your efforts. I did get a compilation without errors, but there is no 64-bit root4star, only 32-bit: [rcas6003] ~/> l /cvmfs/star.sdcc.bnl.gov/packages/SL16j_embed_64b/.sl73_x8664_gcc485/{bin,BIN}/root4* ls: No match.

there is no 64-bit root4star

Ah, good catch. The SL18j_embed revision we’re patching now is one of those that were unlucky enough to have received this patch on Dec 2, 2012 by @fisyak, which effectively disabled the building of root4star in 64-bit builds: 42dc08f#r158551981

Later, on Oct 1, 2018, this was re-enabled by Jerome like this: 2a9af69973?w=1

[plexoos]

Gene, I pushed a commit to SL18j_embed_64bit to overcome this legacy restriction: 0c83707?diff=unified&w=1

You can fetch the change into your local branch and compile the missing packages:

git pull
cons +asps

Also, I'm not sure if this is do-able, but the original SL16j(_embed) used ROOT 5.34.30.

It’s definitely doable, but it will require more significant effort. I’ll add it to my to-do list and revisit it later.
