Description andrii.verbytskyi 2026-03-27 12:13:57 UTC
lhapdf-config --incdir does not show the include directories anymore and instead of it just  prints help+error message.


Reproducible: Always

Steps to Reproduce:
1. run lhapdf-config --incdir
2. See the error+help message.
Actual Results:

user@fedora:~$ lhapdf-config --incdir
lhapdf-config: configuration tool for the LHAPDF
               parton density function evolution library
               https://www.lhapdf.org/

Usage: lhapdf-config [options]
Options:
  --help | -h   : show this help message

  --prefix              : show the installation prefix (cf. autoconf)
  --incdir              : show the path to the LHAPDF C++ header directory
  --libdir              : show the path to the LHAPDF library directory
  --datadir             : show the path to the LHAPDF data directory
  --pythonpath|--pydir  : show the path(s) to the directory containing LHAPDF's Python package

  --cxx                   : returns a compiler string matching that used to build LHAPDF
  --cxxflags              : returns a string matching the compiler flags used to build LHAPDF
  --cflags|--cppflags     : returns a '-I' string for insertion into CPPFLAGS
  --libs                  : returns a '-L/-l' string for insertion into LDFLAGS/LDLIBS
  --ldflags|--libs-only-L : returns a '-L' string for insertion into LDFLAGS
  --ldlibs|--libs-only-l  : returns a '-l' string for insertion into LDLIBS

  --version     : return LHAPDF release version number
Error: Unknown option '--incdir'


Expected Results:

user@fedora:~$ lhapdf-config --incdir
/usr/include

Additional Information:
This is obviously broken upstream. As a quick fix one can add to lhapdf-config:


# Loop over arguments
for opt in "$@"; do
  case "$opt" in
    --help)         print_help && exit 0 ;;
    --h)            print_help && exit 0 ;;
    --version)      echo "6.5.6" && exit 0 ;;
    --prefix)       show_prefix=1 ;;
    --includedir)   show_incdir=1 ;;
    --incdir)       show_incdir=1 ;;  <--------------
    --libdir)       show_libdir=1 ;;
    --datadir)      show_datdir=1 ;;

    --libs-only-l)  show_lflags=1 ;;
    --libs)         show_Lflags=1; show_lflags=1 ;;
    *)              print_help
                    echo "Error: Unknown option '$opt'" >&2
                    exit 1 ;;

Comment 14 andrii.verbytskyi 2026-03-31 08:01:17 UTC
Sorry for not reporting it earlier, just discovered another bug in the updated LHAPDF.
Basically, the logic of `lhapdf-config` was updated so


user@fedora:~/LHAPDFTEST$ 6.5.6/lhapdf-config --ldflags
-L/usr/lib64 -L/usr/lib -L/usr/lib64 -lyaml-cpp
user@fedora:~/LHAPDFTEST$ 6.5.5/lhapdf-config --ldflags
-L/usr/lib -L/usr/lib64 -lyaml-cpp -L/usr/lib64 -lLHAPDF


This logic breaks builds for downstream packages.
I have no fix so far.

Best regards,

Andrii

Comment 15 Mattias Ellert 2026-04-03 07:15:40 UTC
The logic has changed and you need to put both --ldflags and --ldlibs to get the complete set of flags:

$ lhapdf-config --cflags
-I/usr/include -I-I/usr/include
$ lhapdf-config --ldflags --ldlibs
-L/usr/lib64 -L/usr/lib -L/usr/lib64 -lyaml-cpp -lLHAPDF

The double -I-I in the cflags is a bug which I have now fixed in the -3 release.
And puting both -L/usr/lib and -L/usr/lib64 in ldflags is not correct either.

With the new version:

$ lhapdf-config --cflags
-I/usr/include
$ lhapdf-config --ldflags --ldlibs
-L/usr/lib64 -lyaml-cpp -lLHAPDF
$ lhapdf-config --incdir
/usr/include
$ lhapdf-config --includedir
/usr/include
$ lhapdf-config --libdir
/usr/lib64
