Trouble installing git-commit-notifier

Question

git

Hello. I'm trying to install git-commit-notifier . I act according to the instructions:

gem install git-commit-notifier
Then I will build libiconv from the sources. I'm trying to show where it is: gem install git-commit-notifier - --with-iconv-include=/usr/local/lib/libiconv.so.2.2.0 I get a similar output, only the error looks like this: " libxml2 is missing. please visit nokogiri.org/tutorials/installing_nokogiri.html for help with installing dependencies. " I follow the recommendations from the link, I try - again an error. I show where I have libxml2: gem install git-commit-notifier --with-iconv-include=/usr/local/lib/libiconv.so.2.2.0 --with-xml2-include=/usr/local/ lib/libxml2.so.2.7.8

Answer 1

As far as I know, when building a native extension, it needs not only shared-libraries, but also source codes or header files. I don’t know how this problem is solved in centos, but in ubuntu it is usually solved by installing a package with a dev attribute, i.e. libiconv-dev and libxml2-dev.
And by the way, you shove the path shared-library into the parameter for include-files.

Answer 2

Maybe some thread
yum install libxml2-devel

Answer 3

At least on our server, the file /usr/include/iconv.hbelongs to the glibc-headers package (2.5-42.el5_4.3) and
the libxml2 - devel package (/usr/include/libxml2/libxml/parser.h 2.6.26-2.1.2.8 ) I tried to put it, so maybe this information will not help.
extern iconv_t iconv_open (__const char *__tocode, __const char *__fromcode);

Answer 4

So, I decided to give it a try...

cat /etc/redhat-release
CentOS release 5.4 (Final)

sudo yum install rubygems
sudo yum install libxml2-devel
sudo yum install ruby-devel
sudo gem install git-commit-notifier
>>>

libxslt and libxslt-devel are already installed, so I'm not sure if they are needed or not.
