About root6 dependencies

Description

In my previous MacPorts installation (Yosemite 10.0.4), I installed root6 with:

sudo port install root6 +avahi +fftw3 +fitsio +gcc5 +ldap +mysql56 +odbc +postgresql92 +pythia +python34 +sqlite3 +vc +xrootd

and only gcc5 compiler was installed

port installed | grep gcc
gcc5 @5.2.0_0 (active)
  gcc47 @4.7.4_5 (active)
  gcc_select @0.1_8 (active)
  gsl @1.16_3+gcc5 (active)
  libgcc @5.2.0_0 (active)
  pdftk @2.02_0+gcc47 (active)
  py27-numpy @1.9.2_2+gcc5 (active)
  root6 @6.04.02.99_0+avahi+cocoa+fftw3+fitsio+gcc5+graphviz+gsl+http+ldap+minuit2+mysql56+odbc+opengl+postgresql92+pythia+python34+roofit+soversion+sqlite3+ssl+tmva+vc+xml+xrootd (active)

Now, I did a new Yosemite 10.10.5 installation (from scratch) and reinstalled MacPorts. This time, I saw that root6 has gcc5 variant by default so I installed root6 with:

sudo port install root6 +avahi +cxx14 +fftw3 +fitsio +ldap +mysql56 +odbc +postgresql92 +pythia +python34 +sqlite3 +vc +xrootd

adding the cxx14 variant and removing the explicit call "+gcc5". Now it has installed also gcc49:

It seems that adding cxx14 variant has triggered this.. Is really so? What's happening?

I wonder if there is a better way to handle this.

For example, I notice that in my previous installation I had:

port installed | grep num
  py27-numpy @1.9.2_2+gcc5 (active)

Instead now,

port installed | grep num
  py27-numpy @1.9.2_2+gfortran (active)

Which gfortran?

Thanks,

Angelo.

Replying to graziosi.angelo@…:

In my previous MacPorts installation (Yosemite 10.0.4), I installed root6 with:

sudo port install root6 +avahi +fftw3 +fitsio +gcc5 +ldap +mysql56 +odbc +postgresql92 +pythia +python34 +sqlite3 +vc +xrootd

and only gcc5 compiler was installed

By specifying "+gcc5" here, you're requesting that gcc5 be used both for root6 and for all the dependencies of root6 that have a gcc5 variant that were not already installed.

Now, I did a new Yosemite 10.10.5 installation (from scratch) and reinstalled MacPorts. This time, I saw that root6 has gcc5 variant by default so I installed root6 with:

sudo port install root6 +avahi +cxx14 +fftw3 +fitsio +ldap +mysql56 +odbc +postgresql92 +pythia +python34 +sqlite3 +vc +xrootd

adding the cxx14 variant and removing the explicit call "+gcc5". Now it has installed also gcc49:

It seems that adding cxx14 variant has triggered this.. Is really so? What's happening?

Adding the cxx14 variant has not triggered this; rather, not requesting the gcc5 variant has triggered this. Although the root6 port defaults to gcc5 now, I guess some of its dependencies don't default to gcc5 yet. Since you did not request a specific gcc variant, each port used its default. Any port that offers gcc variants should ideally be enhanced to have a gcc5 variant and make it the default. (For most ports, this should be possible, but for some, like pdftk, which I see you have installed, it is not possible right now.)

I wonder if there is a better way to handle this.

For example, I notice that in my previous installation I had:

port installed | grep num
  py27-numpy @1.9.2_2+gcc5 (active)

Instead now,

port installed | grep num
  py27-numpy @1.9.2_2+gfortran (active)

Which gfortran?

I really can't tell you. I've tried to read the compilers 1.0 portgroup to see what it does in this case, but it is too complicated for me to figure out.

Ugh!! This was my mistake! Thanks for clarification..

I can image.. I hope some MacPorts guru can explain this.

Thanks a lot,

Angelo.

From what I understand one half of the mystery has been solved, while asking for clarification about numpy here might not be the best place to get attention from other knowledgable maintainers.

Angelo, please ask on the macports-dev mailing list or on IRC if you are still curious. I'm closing this ticket because I don't think there is anything we can do within the root6 port to change the described behaviour in any way. If any issues are left, those probably belong to the base. If I am wrong, please open a new ticket or reopen this one.

Note: See TracTickets for help on using tickets.
