Package: qt6-base
Tags: patch, ftbfs, hppa
Version: 6.4.2+dfsg
The attached patch fixes this qt6-base "build-from-source" (FTBFS) failure on
hppa:
/usr/bin/ld: /usr/lib/hppa-linux-gnu/libzstd.a(error_private.o): relocation
R_PARISC_DPREL21L can not be used when making a shared object; recompile with
-fPIC
The problem is, that qt6-base suddenly tries to link against the static
library of libzstd.a, while in the past it did linked against the shared
library:
In current failing build (6.4.2+dfsg-1):
-- Found WrapZSTD: 1.5.2 (found suitable version "1.5.2", minimum required is
"1.3")
Full log is here:
https://buildd.debian.org/status/fetch.php?pkg=qt6-base&arch=hppa&ver=6.4.2%2Bdfsg-1&stamp=1675198832&raw=0
while it worked in the past for qt6-base 6.4.2+dfsg~rc1-1
-- Found WrapZSTD: /usr/lib/hppa-linux-gnu/libzstd.so (found suitable version "1.5.2",
minimum required is "1.3")
Full log is here:
https://buildd.debian.org/status/fetch.php?pkg=qt6-base&arch=hppa&ver=6.4.2%2Bdfsg%7Erc1-1&stamp=1672201686&raw=0
The attached patch changes WrapZSTD to prefer the dynamic library.
Thanks,

[PATCH] FindWrapZSTD: Prefer libzstd shared library over static library
On some architectures a static library can not be linked into shared library
because shared libraries may need specific symbol relocations.
This fixes the build on hppa architecture which gives those errors:
/usr/bin/ld: /usr/lib/hppa-linux-gnu/libzstd.a(error_private.o): relocation R_PARISC_DPREL21L can not be used when making a shared object; recompile with -fPIC
/usr/bin/ld: /usr/lib/hppa-linux-gnu/libzstd.a(zstd_v05.o): relocation R_PARISC_DPREL21L can not be used when making a shared object; recompile with -fPIC
/usr/bin/ld: /usr/lib/hppa-linux-gnu/libzstd.a(zstd_v06.o): relocation R_PARISC_DPREL21L can not be used when making a shared object; recompile with -fPIC
/usr/bin/ld: /usr/lib/hppa-linux-gnu/libzstd.a(zstd_v07.o): relocation R_PARISC_DPREL21L can not be used when making a shared object; recompile with -fPIC
/usr/bin/ld: /usr/lib/hppa-linux-gnu/libzstd.a(huf_decompress.o): relocation R_PARISC_DPREL21L can not be used when making a shared object; recompile with -fPIC
