A problem of Planck likelihood about "mkl library" on "cfitsio" #348

Closed Leisures2 closed 8 months ago

Leisures2 commented 8 months ago

Hello everyone : I meet an error when I prepare to configure clik with the Intel mkl library using the code (on Mac) ./waf configure --lapack_mkl=${MKLROOT} --install_all_deps

My attempts

The marked part is about the missing 'cfitsio'. I notice the issue #278 is similar to mine so I download and install 'cfitsio3280' from new website. However it doesn't matter and the 'cfitsio' still remains 'not found'. I also try to use brew to install 'cfitsio' but the result doesn't change too.

Now there's nothing more I can do.... I hope you can help me!

Hi,

The Planck likelihoods can have a bit of a hard time finding things sometimes, you can try the usual of making sure cfitsio appears on the relevant path variables, but you can also try to directly pass the path to Planck with the flag --cfitsio_prefix , e.g. --cfitsio_prefix=$CFITSIO_HOME

Best, Thejs

Hi,

There are installation instructions for cfitsio (and most of the other dependencies the Planck likelihoods need) in the readme.md that comes with the Planck likelihoods (in code/plc_3.0/plc-3.01). With cfitsio specifically, note the importance of compiling it with the option --shared, such that the Planck likelihoods can find it properly.

Cheers, Deanna

I try to recompile cfitsio with the option 'shared' but it minds me that they don't have this term:

(MontePy) durian@MacBook-Pro cfitsio % make --shared
/Library/Developer/CommandLineTools/usr/bin/make: unrecognized option `--shared'
Usage: make [options] [target] ...
Options:
  -b, -m                      Ignored for compatibility.
  -B, --always-make           Unconditionally make all targets.
  -C DIRECTORY, --directory=DIRECTORY
                              Change to DIRECTORY before doing anything.
  -d                          Print lots of debugging information.
  --debug[=FLAGS]             Print various types of debugging information.
  -e, --environment-overrides
                              Environment variables override makefiles.
  -f FILE, --file=FILE, --makefile=FILE
                              Read FILE as a makefile.
  -h, --help                  Print this message and exit.
  -i, --ignore-errors         Ignore errors from commands.
  -I DIRECTORY, --include-dir=DIRECTORY
                              Search DIRECTORY for included makefiles.
  -j [N], --jobs[=N]          Allow N jobs at once; infinite jobs with no arg.
  -k, --keep-going            Keep going when some targets can't be made.
  -l [N], --load-average[=N], --max-load[=N]
                              Don't start multiple jobs unless load is below N.
  -L, --check-symlink-times   Use the latest mtime between symlinks and target.
  -n, --just-print, --dry-run, --recon
                              Don't actually run any commands; just print them.
  -o FILE, --old-file=FILE, --assume-old=FILE
                              Consider FILE to be very old and don't remake it.
  -p, --print-data-base       Print make's internal database.
  -q, --question              Run no commands; exit status says if up to date.
  -r, --no-builtin-rules      Disable the built-in implicit rules.
  -R, --no-builtin-variables  Disable the built-in variable settings.
  -s, --silent, --quiet       Don't echo commands.
  -S, --no-keep-going, --stop
                              Turns off -k.
  -t, --touch                 Touch targets instead of remaking them.
  -v, --version               Print the version number of make and exit.
  -w, --print-directory       Print the current directory.
  --no-print-directory        Turn off -w, even if it was turned on implicitly.
  -W FILE, --what-if=FILE, --new-file=FILE, --assume-new=FILE
                              Consider FILE to be infinitely new.
  --warn-undefined-variables  Warn when an undefined variable is referenced.
  -N OPTION, --NeXT-option=OPTION
                              Turn on value of NeXT OPTION.

Or I understand incorrectly...Should I make before make --shared?

Hi,

Your cfitsio set-up will change a bit based on your machine and configuration, but here's what I do to get it working with Planck. Assuming you've downloaded the latest version of cfitsio and untared it, navigate to the cfitsio directory and then try the following (taken from the cfitsio readme): make clean ./configure CC="gcc -m64" CXX="gcc -m64" CPP="gcc -E" CXXCPP="g++ -E" (this will change depending on your machine) make make shared make install And then when compiling the Planck likelihood, you can use: ./waf configure --lapack_mkl=${MKLROOT} --install_all_deps --cfitsio_islocal

At this point the Planck likelihoods should be able to find cfitsio. If you still get the message complaining about cfitsio not being found, try adding the flag Thejs mentioned as well.

Cheers, Deanna

I follow your steps to make cfitsio "shared", but

ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Clang create a lot of trouble so my unique choice is setting the path --cfitsio_prefix as Thejs mentioned above and I complete the step of configuration successfully. But when I install many warnings about clang appear like:

So now I decide to change clang to gcc to prevent these problems. Thanks!

Thank you for reporting back on the solution that worked! Closing issue as it appears resolved.

Hi, I have replaced clang with gcc as

but the result persists "not found" of "gcc":

It is so ridiculous that I replace clang with gcc successfully but meet problems of pyembed and cfitsio again. I check the config.log

Undefined symbols for architecture arm64:

So it looks like a paradox between x86_64 and arm64. I will try new settings tomorrow and desire your advice.

Hi,

I'm going to close this as it is technically not a MontePython issue. If you found a solution I would appreciate if you can report back, since I haven't seen this problem before.

It seems a bit of an unusual issue, so I'm not sure if these can help, but here is the standard list of places to find information on Planck installations: 1) The MontePython README: https://github.com/brinckmann/montepython_public#the-planck-likelihood-part 2) The Planck README found in your Planck directory at code/plc_3.0/plc-3.01/readme.md 3) Searching for Planck in open and closed MontePython issues as common problems have been addressed many times I think this one has not, though): https://github.com/brinckmann/montepython_public/issues?q=is%3Aissue+Planck 4) Searching for answered Planck issues on the CosmoCoffee forums https://cosmocoffee.info/

In particular you might check 4) as that's a wider community than just MontePython users and it's possible other Mac users encountered this.

Best, Thejs
