如何用Mac的默认64位版本替换MacPort的libiconv? [英] How to replace MacPort's libiconv with Mac's default 64-bit version?

问题描述

MacPorts安装了"libiconv @ 1.14_0 + universal"作为对我系统的依赖性.碰巧是32位格式，当我尝试编译名为Simon Listens的语音识别软件时，它开始引起问题. 在搜寻时，我发现Mac实际上随附了

MacPorts installed "libiconv @1.14_0+universal" as a dependency on my system. This happens to be a 32-bit flavor and it started causing issue when I tried to compile a voice recognition software called Simon Listens. While googling I found out that that Mac actually ships with a 64-bit flavor of libiconv by default and I was able to locate the said files on my system:

$ find /usr/lib -name libiconv*
/usr/lib/libiconv.2.4.0.dylib
/usr/lib/libiconv.2.dylib
/usr/lib/libiconv.dylib

为了使用系统库，我能想到的最快方法是卸载MacPort版本的libiconv，这样系统库最终将被选作后备，因为它必须在楼下的某个地方呈现(我的猜测)路径已经存在.

In order to use the system library, the quickest way I could think of was to uninstall MacPort's version of libiconv so that the system's library would end up getting selected as a fallback as it has to present (my guess) somewhere downstairs on the PATH already.

但是由于依赖关系而失败:

But that failed due to dependecies:

$ sudo port uninstall libiconv @1.14_0+universal
Unable to uninstall libiconv @1.14_0+universal, the following ports depend on it:
...

所以现在我的问题是如何告诉MacPort替换其依赖关系图以指向并使用系统上已经存在的库?

So now my question is how can I tell MacPort to replace its dependency graph to point to and use the library already on my system?

推荐答案

避免MacPorts libiconv问题的另一种方法是构建

Another approach to avoid MacPorts libiconv issues would be to build simon against a fresh MacPorts system plus the necessary packages such as cyrus-sasl2, zlib, portaudio and kdesdk4 in a custom location, e. g. /opt/macports-simon.

以下代码在运行Mac OS X 10.6.8的计算机上对我有用:

The following code worked for me on my machine running Mac OS X 10.6.8:

# compile simon on Mac OS X 10.6.8 using MacPorts for the installation of zlib, portaudio and kdesdk4
# http://www.simon-listens.org
# http://sourceforge.net/projects/speech2text/

# get a root shell
sudo -H -i  

# prevent idle sleep
pmset -a force sleep 0 displaysleep 0 disksleep 0

mv -i /opt/local /opt/local-off
mv -i /usr/local /usr/local-off

cd /tmp
mkdir buildsimon || exit 1
cd buildsimon || exit 1

# create custom /opt/macports-simon to install zlib, portaudio and kdesdk4
# cf. http://guide.macports.org/#installing.macports.source.multiple
MP_PREFIX='/opt/macports-simon'
unset PATH
export PATH='/bin:/sbin:/usr/bin:/usr/sbin'
curl -L -O https://distfiles.macports.org/MacPorts/MacPorts-2.0.4.tar.bz2
tar -xjf MacPorts-2.0.4.tar.bz2
cd MacPorts-2.0.4 || exit 1
./configure --prefix="${MP_PREFIX}" --with-applications-dir="${MP_PREFIX}/Applications"
make
make install

cd /tmp/buildsimon

unset PATH
export PATH="${MP_PREFIX}/bin:/bin:/sbin:/usr/bin:/usr/sbin"

# get the Portfiles and update the system
port -v selfupdate

# install cyrus-sasl2
port -f uninstall cyrus-sasl2
port clean --all cyrus-sasl2
port extract cyrus-sasl2
cd "$(port dir cyrus-sasl2)"/work/cyrus-sasl-2.1.23
printf '%s\n' H '/\(darwin\[15\]\)/s//\1./g' wq | sudo ed -s config/ltconfig
printf '%s\n' H '/\(darwin\[15\]\)/s//\1./g' wq | sudo ed -s saslauthd/config/ltconfig
cd /tmp/buildsimon
port -f -s install cyrus-sasl2
otool -L /opt/macports-simon/lib/libsasl2.dylib

port -f install zlib
port -f install portaudio
port -f install kdesdk4

port installed zlib portaudio kdesdk4 cyrus-sasl2
