Creating dynamic shared library (i.e. liblpsolve55.so) #2

Closed ns-1m closed 11 years ago

ns-1m commented 11 years ago

Hi,

I want to use your configure-enable lpsolve inorder to create dynamic library (i.e. liblpsolve55.so) together with your current static library (liblpsolve55.a).

Would be possible to show how to create liblpsolve55.so?

Thanks.

What happens when you try: 

./configure --enable-shared
make liblpsolve55.so

from the untarred lpsolve-5.5.0.10i directory?

ns-1m commented 11 years ago

OK. Thanks.

However, I got error (below).

BTW, I am using Mac OS X. You configure enabled lpsolve works in Mac OS X.

What I wanted is *.dylib but I could rename liblpsolve55.so if it is working :-).

It is not working.

I don't own a OSX or have access to one. So unless you want to buy me Mac, you are on your own.

In a sense this really has nothing to do with the Ruby library or gem. What you want to know is how to build lpsolve 5.5.0.12 with shared libraries. Admittedly I've made a couple of additions to the stock lpsolve 5.5.0.12, so you shouldn't hit them up with questions about my modified code.

But if you knew how to build whatever you want from the stock 5.5.0.12, it would be clear how to do it here as well. My additions to lpsolve 5.5.0.12 are totally portable and have nothing to do with OS-specific code.

If you do figure it out, feel free to add this information to the wiki or send back patches. Thanks.

Reading your answer again above, where can I get your lpsolve stock 5.5.0.12 which has configure enabled?

Where could I download it?

Yes, I am helping create NO PAIN install for LPSolve for Mac OS X as I did GLPK/MathProg i.e. helped Andrew created installation for Linux and Mac OS X.

Thanks again.

OK.

That's what I am have been using.

Most of the time, most of the linux stuff work in my modified Mac OS X

My 5 years old questions on how to compile LPSolve XLI dynamic libraries for Windows and Linux has not been addressed. So, I am trying to address this question myself :-).

Thanks.
