Re: [Help-glpk] glpk on amazon linux ami

[Nigel Galloway]

AWS has a discussion forum, currently with no questions about installing the AWS GLPK package. That may be a better place to ask. I notice the available packages include gcc4.7, there are many questions and answers about installing that, see https://forums.aws.amazon.com/search.jspa?objID=f30&q=gcc&x=14&y=14. Given that the AWS package is GLPK4.40, you may be better installing gcc with help from the above forum if needed, then obtaining the latest glpk (4.48) and compiling it, with help from this group and the wiki as needed.

 

A final option is that rpm packages can be installed on AWS. You could obtain any rpm for 4.48 and install that.

Hi

Has anyone used glpk on an Amazon ec2 micro instance? I am having trouble getting it working

 

sudo yum install glpk

  works fine

 

sudo yum list installed

  includes "glpk.x86_64                     4.40-1.1.4.amzn1                     @amzn-main"

 

and 

 yum search glpk

gives

 

============================== N/S Matched: glpk ===============================

glpk-devel.x86_64 : Development headers and files for GLPK

glpk-doc.x86_64 : Documentation for glpk

glpk-static.x86_64 : Static version of GLPK libraries

glpk-utils.x86_64 : GLPK-related utilities and examples

glpk.i686 : GNU Linear Programming Kit

glpk.x86_64 : GNU Linear Programming Kit

 

But from here how do you actually run glpsol or even call glpk.h as a library? 

 

<glpk.h> is not found if I include it in a c file or if I try gem install of rglpk

 

[ec2-user rubygems-1.8.11]$ sudo gem install rglpk

I get 

checking for main() in -lglpk... no

ERROR: Cannot find the GLPK library, aborting.

 

a 'find / -name glpk*' does not find glpk files either. 

 

   I could be doing something stupid with linux rather than linux on ec2. But any help you can provide me on how to get a "hello world" glpk example running on amazon ec2 linux would be great.
