Caveats when switching Ada projects from windows To Linux

Caveats when switching Ada projects from windows To Linux

[Hubert]

So here I am, having written my first working Ada program, and it's 
actually pretty useful. Now I want to transfer it to my Linux machine 
and compile it there. After running into the obvious problems (directory 
name capitalization mismatch and \ changed to / ) I am now faced with 
the perplexing message that there are no Ada source files in the project.

I am using the SourceDirs option in GPS where I just give the 
directories with the source files. For instance, one gpr file contains 
the line

    FOR Source_Dirs USE (".");

which works fine on windows but not in Linux, although I copied the 
directory hierarchy 1:1

Are there any tricks I have to be aware of when moving a project to Linux?

Thanks

What are the names of your files looking like, expecially the suffixes?

You might take a look at my pdf document on bringing up GNAT
in Ubuntu Linux.  There are a bunch of seemingly minor details
that can impede progress if you are used to Windows and moving
over to Linux.  The pdf document is in this group's forum on about
Oct. 19, 2014.  The GNAT User Guide is pretty good - but it doesn't
deal with some of the subtleties.  I'm not interested in discussions
about GNAT versus other compilers or Linux distributions.  I think
what's in the pdf can be helpful for understanding what you might
need to do if you make a choice other than GNAT for your work.

Oh ok, thats the google archive for the newsgroup. I thought it was some 
sort of real Forum somewhere, but thanks

Sorry for the confusion.  David was correct.

Make sure all your file names are lower case.

thanks that did the trick. I made filenames with capital letters as the 
first ones to make them more readable. Just one more reason to need a 
package browser because now the filenames look even more alike :(

Well, my program compiles fine on Linux now. I want to put in on 
sourceforgenet sometime soon, once I have used it a bit in case there 
are more bugs.

It is essentially a server application that can be used by any client to 
output debug prints to, like the debug window in Visual Studio. GPS does 
not have anything like that and just shows the program's stdout in that 
little window at the bottom. On top of that you can filter the output 
based on channels and threads. the whole thing is based on my previous 
experience with debug output and what I needed. I think it's pretty 
neat. Alas for now I don't have plugins to debug Ada code, only C code 
(since that's what I wrote it for) but it should be easy to add Ada 
stubs to go with an Ada program

The '/' vs '\' is a non-issue.
Windows has been able to handle '/' separators since at least Win-98.

Well what I meant is that I am using \ but linux doesn't seem to handle 
them. But I also had uppercase filenames so I don't know which of these 
caused the error

as long as you're running in windows.

You have to be careful in Linux, which only deals with `/` .

Note also if you start to look for a file with a name that starts with `/`,
like `/foo`, then the file system will look for a directory `foo' in the
root directory.  If you ask for the file `foo', that's a relative location
and will probably be in the current directory (depending on where you've set
your current directory).

In addition, if you're aiming to use AWS in Windows, you'll be working with
interfaces that use POSIX, which I believe requires the Unix slash convention.
