The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Glibc and the "undefined reference to __ctype_b" error

Asked by mcwojtekk in Linux Setup

Tags: reference, undefined, __ctype_b

After installing Redhat 9.0 some older libraries (part of Talarian Smartsockets if you are interested) are no longer working for us.
While linking, the error message "undefined reference to __ctype_b" appears - this is a feature of glibc no longer avaiable in glibc-2.3.2-11.9, but avaiable in glibc-2.2.

To gain a better understanding of the problem you can also read
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=91290

I will give points for a detailed description of a solution, those come to mind:

1. Install older version of glibc, i.e. 2.3.2-5, the last version that seems to work. Questions: Will Redhat still work, how to downgrade an installation of glibc
   (parameters to force rpm to install older version?)

2. Parallel install of two glibc versions? Is this even possible?

3. A patch/compatibility addon for the newer version of glibc, I haven't found one but perhaps I have not looked hard enough?

Please try to give a detailed description of the solution, I'm still a bit shaky when it comes to managing libraries and dependencies in Linux.
