Dear Yann E. MORIN, On Wed, 11 Jun 2014 23:32:46 +0200, Yann E.

We need to autoreconf to be able to patch our the 'ln --relative' calls. And to be able to autoreconf, we need this libgcrypt.m4 stuff. To me, hacking around the 'ln --relative' problem is not a proper solution. Because the next time we need a patch for systemd that requires autoreconf (like if we backport a fix from upstream or another change), then we will be back to the current situation where autoreconf cannot be done with libgcrypt.m4. So I agree with the solution proposed by Eric here to bundle the libgcrypt.m4 file. Best regards, Thomas

OK, I'm fine with the solution. I was just pointing out that an alternative existed, wihch looked less ugly to me. But OK. I'll take some time to do a proper review on this patch a bit later.

This patch installs a copy of libgcrypt.m4 from the libgcrypt source tarball to systemd m4 directory. Libgcrypt uses a custom m4 macro and not pkg-config to check if the development files are available. Though libgcrypt support is optional in systemd, this macro should be available whenever autoreconf is used, otherwise the re-configuration will fail with: configure.ac:616: warning: macro 'AM_PATH_LIBGCRYPT' not found in library The call to autoreconf is required, as it is needed by the patch which solves the `ln --relative` issue. As asking the user to install the development package of libgcrypt on the host machine or adding libgcrypt as a build dependency to systemd is not acceptable, the required file is added to the m4 directory.
