Description Remi Collet 2019-06-12 12:11:05 UTC

Context: PHP upstream is wortking on switching most of its build system to pkg-config.

For libxslt / libexslt output may be different across distro.

Fedora: 

$ pkg-config --libs libxslt
-lxslt -lm -lxml2 
$ pkg-config --libs libexslt
-lexslt -lxslt -lm -lgcrypt -ldl -lgpg-error -lxml2 

On deb distro

$ pkg-config --libs libxslt
-lxslt -lxml2
$ pkg-config  --libs libexslt
-lexslt -lxslt -lxml2

Indeed, debian dev. apply some patches:

https://salsa.debian.org/xml-sgml-team/libxslt/blob/master/debian/patches/0002-fix-autoconf-automake.patch
https://salsa.debian.org/xml-sgml-team/libxslt/blob/master/debian/patches/0001-patch-xslt-config-to-add-private-libraries.patch

I think such change should be discussed upstream

Comment 1 Ben Cotton 2019-08-13 16:47:46 UTC

This bug appears to have been reported against 'rawhide' during the Fedora 31 development cycle.
Changing version to '31'.

Comment 2 Jakub Jelen 2019-10-11 15:20:09 UTC

Can you clarify what is your expectation from this bug report?

The libexslt is now built against libgcrypt so it needs to be linked against that even if you link some other applications. The same for gpg-error, which is library providing the error strings for gcrypt.

For the -lm, I think that it should also go there in both places. Even though the HAVE_POW/FLOOR/FABS are not used, the respective functions are used around the code without gating.

Comment 3 Remi Collet 2019-10-14 06:50:08 UTC

> Can you clarify what is your expectation from this bug report?

This about what pkg-config --libs should provides

- libraries used by the lib itself (current output)

OR 

- libraries needed by other app using the lib


Other lib (such as libgcryt) are usual only needed for static build, not in a shared one.
Some projects also provide a -static of -private configuration for such use case.
