pkgconf 3.0.4-1: personality files installed in /etc/pkgconfig/personality.d but binary searches /usr/{lib,share}/pkgconfig/personality.d

Hi,  

  

The pkgconf 3.0.4-1 update (2026-07-26) appears to have a packaging  

mismatch that breaks all cross-personality lookups, and with them a  

large number of CI pipelines that build OCaml/opam projects on Windows  

(opam probes mingw-w64 libraries via `pkgconf
--personality=<triplet>-w64-mingw32 <lib>`).  

  

Details:  

  

- pkgconf 3.0.4-1 still installs the personality files at  

`/etc/pkgconfig/personality.d/{i686,x86_64}-w64-mingw32.personality`,  

same as 2.5.1-1.  

- But libpkgconf8 3.0.4-1 is compiled with the personality search path  

`/usr/lib/pkgconfig/personality.d:/usr/share/pkgconfig/personality.d`  

(visible with `strings /usr/bin/cygpkgconf-8.dll`), while  

libpkgconf7 2.5.1-1 used `/etc/pkgconfig/personality.d`. I suspect  

the switch to the meson build changed the default personality dir.  

- When the personality file is not found, libpkgconf silently falls  

back to the default (native) personality  

(`pkgconf_cross_personality_find` returns  

`pkgconf_cross_personality_default()`), so  

`pkgconf --personality=x86_64-w64-mingw32 gmp` searches the native  

paths, finds no gmp.pc, and exits 1 with no diagnostic.  

  

Reproduction (on an up-to-date installation with mingw64-x86_64-gmp
installed):  

  

$ pkgconf --personality=x86_64-w64-mingw32 gmp; echo $? 1  

  

Expected (2.5.1-1 behavior): exit 0.  

  

Workaround we are using in CI, since the XDG lookup path is consulted  

too:  

  

export XDG_DATA_DIRS=/etc:/usr/local/share:/usr/share  

  

Suggested fix: either configure the personality directory back to  

/etc/pkgconfig/personality.d when building, or move the personality  

files to /usr/share/pkgconfig/personality.d in the packaging.  

  

Impact context: every GitHub Actions workflow using ocaml/setup-ocaml  

on windows-latest with mingw depexts (gmp, zlib, ...) started failing  

within hours of the 3.0.4-1 release; examples include rocq-prover/rocq  

and ahrefs/ocannl.  

  

Thanks for all the work on Cygwin!
