Many FTP servers block connections from Tor and some
VPN servers. HTTP servers don't do this normally.
Example of failed FTP download attempt of binutils-2.24.tar.bz:
$ torsocks wget ftp://ftp.gnu.org/pub/gnu/binutils/binutils-2.24.tar.bz2
--2014-07-20 13:26:48-- ftp://ftp.gnu.org/pub/gnu/binutils/binutils-2.24.tar.bz2

Retrying.

Trying download from Tor Browser, I get error message:
425 Security: Bad IP connecting.
HTTP URLs were added to FTP URLs-only packages.
In many cases, ftp://ftp.gnu.org can be accessed
from http://ftp.gnu.org
If both URLs of a package are FTP, then one of them
was replaced with HTTP.
Command to check that those packages can be build successfully
if behind Tor:
$ torsocks make autoconf automake binutils bison cloog coreutils file freetds gcc gdb gettext gmp gnutls gperf isl libbluray libffi libgcrypt libgpg_error libidn libmicrohttpd libpng libxml2 libxslt m4 pthreads-w32 sed dcmtk mpfr
I've run the test above successfully.
Since we need pkgconf for Cflags.private support, it seems like a
logical place for these types of config files instead of being
spread over Makefile, binutils, and gcc.
Most of the automatic conversion was done using the following Python script:
import os
import re
pkgs = sorted(mkfile[:-len('.mk')] for mkfile in os.listdir('src') if mkfile.endswith('.mk'))
with open('index.html', 'rb') as f:
index = f.read()
pkgs_index = re.findall('<td class="package">([^<]*)</td>', index)
assert pkgs_index == pkgs
versions = dict(re.findall('<td id="([^"]*)-version">([^<]*)</td>', index))
assert sorted(versions.keys()) == pkgs
for pkg in pkgs:
version = versions[pkg]
with open('src/' + pkg + '.mk', 'rb') as f:
mk = f.read()
checksumpos = mk.index('\n$(PKG)_CHECKSUM ')
versionline = '\n$(PKG)_VERSION := %(version)s' % {'version': version}
newmk = mk[:checksumpos] + versionline + mk[checksumpos:]
with open('src/' + pkg + '.mk', 'wb') as f:
f.write(newmk)
