C-extension problem

Dear list.

After reading through this walkthrough (1) of compiling c-extensions on
Windows I was finally able to build the pickaxe example on two different
PC’s. One with Visual Studio 2003, the other with Visual C++ express
2005.
Both compiled, only one worked. This raises some issues.

I) Should I try to fix this? I mean, will working with C-extensions
bring
me down the road of never-ending versioning/library/compiler/…
problems.

II) If yes, how to fix the technical issues at hand today?

Any suggestions would be very welcome.

Anyway, here’s what happened.

Building on VS 2003 gave a working result at first try. C++ express 2005
however gave two distinct errors when running

irb: require ‘Test’

GUI warning-box:
ruby.exe - Unable to Locate Component
This application has failed to start because MSVCR80.dll was not
found.
Re-installing the application may fix this problem.

irb: Load error 126 …

After searching from mscvr80.dll, finding it here(2) and copying it to
c:\windows\system32 the following error appeared:

irb: require ‘Test’

GUI warning-box
Microsoft Visual C++ Runtime Library
Rumtime Error!
Program: c:\progra~1\ruby\bin\ruby.exe
R6034

incorrectly
Please contact the application’s support team for more information.

Note that I had to install Microsofts Platform SDK from MSDN seperately.

Hello,
How did you compile the example in 2003? I am tring to do it with the
makefile not a compiler. When I create a blank c++ console project for
the
code it gives me linking errors.
Thank you for any help

Sorry about the lack of details. I also used the makefile approach.

I used textpad, a simple text-editor, for writing the .c-code and then
extconf.rb and nmake.exe from VS 2003.exe. The walkthrough in footnote
(1)
was very helpfull, although I must agree that this i cumbersome.

Note that I had to install not only VS2003, but also the Platform SDK
(for
2003-server, but works for my XP-sp2) to get it all going.

Sorry to bug you for more details. How do you run nmake.exe from 2003?

No problem. Actually I don’t run it from within 2003, I open a
command-window, cd to the right directory and just run nmake.

You should really read this:

hello
A few more questions, Where was your source file? I used the one click
installer and i do not see the scr folder. I downloaded the tar source
from the ruby website and i am using that.

Nmake. When i type it in the command line it does not recognize it. I
set up the variables for the system like the website said to. If I use
the nmake in the VC7\bin i get the cl is not recognized

The echo shows what should be there and extconf.rb does what is should.

Its the damn Nmake!

Sorry to bug you for more details. How do you run nmake.exe from 2003?

Avoid compiling with Visual C++ 2005 for now. There are some …
changes that Microsoft has made. I am working on compiling with Visual
C++ 2005 and have a couple of patches to finish trying from Nobu that
may help alleviate this situation.

I get this error when tring nmake.

Stop.

I dont see where in the make file that line is. also where in that
line there just just a dot?

Again, if you’re trying this with Visual Studio 2005, please hold off.
I am preparing a comprehensive set of instructions.
