[pkg-gnupg-maint] Bug#846889: gnupg2: FTBFS on hppa - Please don't link static version with -pie on hppa

[John David Anglin]

Source: gnupg2
Version: 2.1.16-2
Severity: normal

Dear Maintainer,

The build fails here:

make[2]: Entering directory '/<<PKGBUILDDIR>>/build-gpgv-static/g10'
gcc     -Wall -Wno-pointer-sign -Wpointer-arith  -g -O2 -fdebug-prefix-map=/<<PKGBUILDDIR>>=. -Wformat -Werror=format-security  -pie -static -o gpgv gpgv.o build-packet.o compress.o  free-packet.o getkey.o keydb.o keyring.o seskey.o kbnode.o mainproc.o armor.o mdfilter.o textfilter.o progress.o misc.o rmd160.o openfile.o keyid.o parse-packet.o cpr.o plaintext.o sig-check.o keylist.o pkglue.o ecdh.o verify.o ../kbx/libkeybox.a ../common/libcommon.a ../common/libgpgrl.a -lz    -lgcrypt -L/usr/lib/hppa-linux-gnu -lgpg-error

Full log is here:
https://buildd.debian.org/status/fetch.php?pkg=gnupg2&arch=hppa&ver=2.1.16-2&stamp=1479760527

The build will complete successfully if "-pie" is removed from the following
line in debian/rules:
        cd build-gpgv-static/g10 && $(MAKE) LDFLAGS="$$LDFLAGS -pie -static" gpg
v

PIE support is not well tested on hppa.  Further, gcc on hppa is not built
with --enable-pie-default.  So, archive libraries and executable code are
not built by default with -fPIE.  So, in general, linking with -pie and -static
isn't going to work.

As things stand, the crt* files in gcc are not position independent except
for the shared versions.  They would be if gcc was built with --enable-pie-default.

There is also an issue that the startup file from glibc is not position
independent on hppa.

So, for now, I think the best approach is to remove "-pie" from the above
statement on hppa.

Regards,
Dave Anglin
