hdf5 @1.14.4.2_1+cxx+fortran+gcc13+hl: error: 'PATH_MAX' undeclared (first use in this function)

[jvianalopes (João Manuel Viana Parente Lopes)]

Hi,

I tried to install hdf5 port with:

sudo port -v install hdf5  +gcc13

And it aborts with an error:

---

make[2]: Leaving directory `/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_science_hdf5/hdf5/work/hdf5-1.14.4.2/src'
make[1]: *** [all] Error 2

---

moving to the directory:

cd /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_science_hdf5/hdf5/work/hdf5-1.14.4.2

and trying to compile:

make

Give-me the error:

---

If complaints about this PATH_MAX definition. Do you have any suggestions? I was able to compile it with gcc12

Thanks in advance

Please attach the main.log file.

PATH_MAX is defined in <limits.h>. Sounds like hdf5 hasn't included it here. This would be an upstream bug that should be ​reported to the developers.
