Fix FreeBSD compilation

[ysangkok]

• Do not use copy-dt-needed-entries for FreeBSD
• Do not link libdl on FreeBSD
• Use pkg-config
• Can't assume SOL_LOCAL is defined

[ysangkok]

@edolstra , any comments on this?

[garbas]

this should also fix #304
@tomster do you have any chance to try this PR?

[tomster]

i've tried to install this with the following steps:

• created a new jail on a 10.2-RELEASE system
• inside the jail i installed
  • gmake
  • git
  • autoconf
  • bash
• i then cloned https://github.com/ysangkok/nix.git and switched to the freebsd-fixes branch
• cd-ed into the directory
• ran bash
• ran autoconf
• ran ./configure

that errored with:

[...]
checking for openssl... /usr/bin/openssl
./configure: 5449: Syntax error: word unexpected (expecting ")")

were any of the above steps wrong? should i try this differently?

[tomster]

i retried the above by actually following my own notes that (luckily) made in #304 but i still never got past ./configure (with the same error as above)

i forgot to mention above that i also already had an error when running autoconf:

configure.ac:74: error: possibly undefined macro: AC_DEFINE If this token and others are legitimate, please use m4_pattern_allow. See the Autoconf documentation.

perhaps that is relevant?

[lucabrunox]

@tomster AC_DEFINE is from pkgconfig m4... did you install pkgconfig in the jail?

[tomster]

@tomster Please follow the build instructions. It should work if you use the bundled bootstrap.sh script instead of manually invoking autoconf. The bootstrap script uses autoreconf, which does a few things before invoking autoconf.

[manueljacob]

@tomster Also you should make sure ./configure is executed with Bash (e.g. by running bash ./configure).

[ysangkok]

Pull request #657 is better.

[tomster]

FTR i tried the bootstrap approach in the linked build instructions. after installing automake this allowed bash configure to complete.

however, running gmake yielded this:

root@nix:~/nix # gmake
  GEN    Makefile.config
  GEN    doc/manual/manual.xmli
doc/manual/local.mk:21: recipe for target 'doc/manual/manual.xmli' failed
gmake: *** [doc/manual/manual.xmli] Error 1

[ysangkok]

@tomster: Check configure.log (maybe past the relevant part here, if you cannot figure it out), you may need the packages libxslt, docbook-utils or libxml2. These are just educated guesses though, but see #506 .

[tomster]

@ysangkok thanks, it's all been resolved over at #657 :-)
