Hi Everyone, I was looking at the ldd dependencies of emacs-27.1-rc1. It shows a dependency on GnuPG warez: emacs-27.1$ ldd src/emacs linux-vdso.so.1 (0x00007fffc4aec000) librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007fb044395000) ... libgcrypt.so.20 => /lib/x86_64-linux-gnu/libgcrypt.so.20 (0x00007fb04216a000) libgpg-error.so.0 => /lib/x86_64-linux-gnu/libgpg-error.so.0 (0x00007fb041f55000) Now, the rub here is, I built updated GnuPG libraries for Emacs: emacs-27.1$ ls ~/tmp/ok2delete/lib/*error* /home/jwalton/tmp/ok2delete/lib/libgpg-error.la /home/jwalton/tmp/ok2delete/lib/libgpg-error.so /home/jwalton/tmp/ok2delete/lib/libgpg-error.so.0 /home/jwalton/tmp/ok2delete/lib/libgpg-error.so.0.29.0 emacs-27.1$ ls ~/tmp/ok2delete/lib/*gcrypt* /home/jwalton/tmp/ok2delete/lib/libgcrypt.la /home/jwalton/tmp/ok2delete/lib/libgcrypt.so /home/jwalton/tmp/ok2delete/lib/libgcrypt.so.20 /home/jwalton/tmp/ok2delete/lib/libgcrypt.so.20.2.6 The worry is, those stupid path problems that have plagued Linux for the last 25 years or so. Programs still can't load the correct damn library at runtime. $ readelf -d src/emacs | grep -E 'RPATH|RUNPATH' 0x000000000000001d (RUNPATH) Library runpath: [$ORIGIN/../lib:/home/jwalton/tmp/ok2delete/lib] PKG_CONFIG_PATH is set properly. There does not appear to be a configure setting for GnuPG. ========== $ ./configure --help ... X features: --x-includes=DIR X include files are in DIR --x-libraries=DIR X library files are in DIR System types: --build=BUILD configure for building on BUILD [guessed] --host=HOST cross-compile to build programs to run on HOST [BUILD] Optional Features: --disable-option-checking ignore unrecognized --enable/--with options --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no) --enable-FEATURE[=ARG] include FEATURE [ARG=yes] --disable-ns-self-contained disable self contained build under NeXTstep --enable-locallisppath=PATH directories Emacs should search for lisp files specific to this site --enable-checking[=LIST] enable expensive checks. With LIST, enable only specific categories of checks. Categories are: all,yes,no. Flags are: stringbytes, stringoverrun, stringfreelist, structs, glyphs --enable-profiling build emacs with low-level, gprof profiling support. Mainly useful for debugging Emacs itself. May not work on all platforms. Stops profiler.el working. --enable-autodepend automatically generate dependencies to .h-files. Requires gcc, enabled if found. --enable-gtk-deprecation-warnings Show Gtk+/Gdk deprecation warnings for Gtk+ >= 3.0 --disable-build-details Make the build more deterministic by omitting host names, time stamps, etc. from the output. --disable-largefile omit support for large files --enable-gcc-warnings[=TYPE] control generation of GCC warnings. The TYPE 'yes' means to fail if any warnings are issued; 'warn-only' means issue warnings without failing (default for developer builds); 'no' means disable warnings (default for non-developer builds). --enable-check-lisp-object-type Enable compile time checks for the Lisp_Object data type, which can catch some bugs during development. --enable-link-time-optimization build with link-time optimization (experimental; see INSTALL) --disable-silent-rules verbose build output (undo: "make V=0") --enable-cross-guesses={conservative|risky} specify policy for cross-compilation guesses --disable-acl do not support ACLs Optional Packages: --with-PACKAGE[=ARG] use PACKAGE [ARG=yes] --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no) --without-all omit almost all features and build small executable with minimal dependencies --with-mailutils rely on GNU Mailutils, so that the --without-pop through --with-mailhost options are irrelevant; this is the default if GNU Mailutils is installed --with-pop Support POP mail retrieval if Emacs movemail is used (not recommended, as Emacs movemail POP is insecure). This is the default only on native MS-Windows. --with-kerberos support Kerberos-authenticated POP --with-kerberos5 support Kerberos version 5 authenticated POP --with-hesiod support Hesiod to get the POP server host --with-mail-unlink unlink, rather than empty, mail spool after reading --with-mailhost=HOSTNAME string giving default POP mail host --with-sound=VALUE compile with sound support (VALUE one of: yes, alsa, oss, bsd-ossaudio, no; default yes). Only for GNU/Linux, FreeBSD, NetBSD, MinGW, Cygwin. --with-pdumper=VALUE enable pdumper support unconditionally ('yes', 'no', or 'auto': default 'auto') --with-unexec=VALUE enable unexec support unconditionally ('yes', 'no', or 'auto': default 'auto') --with-dumping=VALUE kind of dumping to use for initial Emacs build (VALUE one of: pdumper, unexec, none; default pdumper) --with-x-toolkit=KIT use an X toolkit (KIT one of: yes or gtk, gtk2, gtk3, lucid or athena, motif, no) --with-wide-int prefer wide Emacs integers (typically 62-bit); allows buffer and string size up to 2GB on 32-bit hosts, at the cost of 10% to 30% slowdown of Lisp interpreter and larger memory footprint --without-xpm don't compile with XPM image support --without-jpeg don't compile with JPEG image support --without-tiff don't compile with TIFF image support --without-gif don't compile with GIF image support --without-png don't compile with PNG image support --without-rsvg don't compile with SVG image support --without-lcms2 don't compile with Little CMS support --without-libsystemd don't compile with libsystemd support --with-cairo compile with Cairo drawing --without-xml2 don't compile with XML parsing support --with-imagemagick compile with ImageMagick image support --without-json don't compile with native JSON support --without-xft don't use XFT for anti aliased fonts --without-harfbuzz don't use HarfBuzz for text shaping --without-libotf don't use libotf for OpenType font support --without-m17n-flt don't use m17n-flt for text shaping --without-toolkit-scroll-bars don't use Motif/Xaw3d/GTK toolkit scroll bars --without-xaw3d don't use Xaw3d --without-xim at runtime, default X11 XIM to off --with-ns use Nextstep (macOS Cocoa or GNUstep) windowing system. On by default on macOS. --with-w32 use native MS Windows GUI in a Cygwin build --without-gpm don't use -lgpm for mouse support on a GNU/Linux console --without-dbus don't compile with D-Bus support --with-gconf compile with Gconf support (Gsettings replaces this) --without-gsettings don't compile with GSettings support --without-selinux don't compile with SELinux support --without-gnutls don't use -lgnutls for SSL/TLS support --without-zlib don't compile with zlib decompression support --without-modules don't compile with dynamic modules support --without-threads don't compile with elisp threading support --with-file-notification=LIB use a file notification library (LIB one of: yes, inotify, kqueue, gfile, w32, no) --with-xwidgets enable use of some gtk widgets in Emacs buffers (requires gtk3) --without-makeinfo don't require makeinfo for building manuals --without-compress-install don't compress some files (.el, .info, etc.) when installing. Equivalent to: make GZIP_PROG= install --with-gameuser=USER_OR_GROUP user for shared game score files. An argument prefixed by ':' specifies a group instead. --with-gnustep-conf=FILENAME name of GNUstep configuration file to use on systems where the command 'gnustep-config' does not work; default $GNUSTEP_CONFIG_FILE, or /etc/GNUstep/GNUstep.conf --with-x use the X Window System --without-libgmp don't use the GNU Multiple Precision (GMP) library; this is the default on systems lacking libgmp. --without-included-regex don't compile regex; this is the default on systems with recent-enough versions of the GNU C Library (use with caution on other systems).
