http://d.puremagic.com/issues/show_bug.cgi?id=11171 Summary: Text relocations in Phobos shared library Product: D Version: D2 Platform: All OS/Version: Linux Status: NEW Severity: normal Priority: P2 Component: Phobos AssignedTo: nobody puremagic.com ReportedBy: public dicebot.lv Have noticed that issue during package maintenance for Arch Linux and reporting by Martin Nowak request. Arch Linux automatically verifies all packages targeting official repos with own `namcap` tool. At some point I have noticed it warning me that `libphobos2.so` has text relocations. This is how package is built: https://github.com/Dicebot/Arch-PKGBUILDs/blob/master/dmd/PKGBUILD Essentially it is just `make -f posix.mak MODEL=$_archbits DMD=$srcdir/dmd/src/dmd RELEASE=1` $ uname -a 2013 x86_64 GNU/Linux $ readelf -d /usr/lib/libphobos2.so | grep TEXTREL 0x0000000000000016 (TEXTREL) 0x0 $ eu-readelf -r /usr/lib/libphobos2.so | wc -l 18615 -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

http://d.puremagic.com/issues/show_bug.cgi?id=11171 P.S. version of shared library in question is https://www.archlinux.org/packages/community/x86_64/libphobos/ , it can be installed at any point by standard package manager (pacman) -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

http://d.puremagic.com/issues/show_bug.cgi?id=11171Likely, but it's not just Gentoo. I use Grsecurity kernel on Debian and get this error: ./prog: error while loading shared libraries: /usr/local/lib/libphobos2.so.0.64: cannot make segment writable for relocation: Permission denied The only solution is to disable MPROTECT for given exacutable. http://pax.grsecurity.net/docs/mprotect.txt -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
