Details

Description:
-fPIC flag is missing while building the libraries
This prevents other software to build with this library

NOTE: this same issue appeared in a previous bug report: https://bugs.archlinux.org/task/30010
After that report the PKGBUILD was updated with -fPIC but this 2019.1 commit removed it: https://git.archlinux.org/svntogit/packages.git/commit/trunk/PKGBUILD?h=packages/qhull&id=8e9850ad8332d316c7f705e392e1db6ccd6dea2c

Additional info:
* package version(s): qhull 2019.1-1

* config and/or log files etc.
build output:
/usr/bin/ld: /usr/lib/libqhullstatic.a(global.c.o): relocation R_X86_64_PC32 against symbol `qh_qh' can not be used when making a shared object; recompile with -fPIC

* link to upstream bug report, if any
This task depends upon

Reason for closing:  Fixed
Additional comments about closing:  2019.1-2 builds libqhullcpp.a with -fPIC and drops other static libs as per Arch policy

Arch automatically compiles all shared libs with PIC so I think only libqhullstatic*.a static lib has this issue. Fedora has patch which link executables against shared libs[1]. They also remove libqhullstatic*.a[2].

Some other things: "make VERBOSE=1" will show more compilation details in logs. You may also consider getting rid of RPATHs[3] (you can confirm they exist with checksec.
