I have made my ROS project down, and have tested the program successfully, then i need pack my project and give it to my customer.
I am confused about how to hide my source code and pack my whole ROS project into one application maybe, can anyone help me?
The easiest way to do this is to create a shared object (that will hide all your source code).
This can be done in the CMakeList with add_library.
Once you have your mystuff.so, you can give it to your costumer (along with an example main.cpp and some documentation).
Your costumer will put a target_link_library in his CMakeList and will be able to use your stuff.

I am nearing the completion of a small project to manage the roles tables in a standard MVC5 application. The code is pretty much encapsulated. What are my options for using this 'package' in other projects?
Can I compile it into something? I know this type of action is possible, I'm just not familiar with the options available to me or the steps to do this. Links to sites that have tutorials are fine. Is creating a Nu Get package the only way to go, or is that even in the ballpark of what I'm asking. I say Nu Get, but I don't mean for public consumption, only for my consumption.
Will the finished 'whatever' include it's controller class, view models and views? Will I be able to easily manage updates? etc.
Creating a Nuget package is one way. I have created a local repository of common utilities for this purpose. But I usually use it just for DLLs. I use Nuget Package Explorer for its ease of use since its just me using the packages most of the time. Not sure its possible to place the files in specific directories.
Files in the content folder are copied to the root of your application when the package is installed. - Nuget
The alternative is to create an item template. I used to use this method for class files I want in my code but I can't see why you couldn't do it for the rest. Works well and isn't too hard to set up. There are dozens if not 100s of tutorials on the subject. Here is one on code project.
I would like to Display a Scratch Project (.SB) file within my Delphi EXE file. I would like to know if it is possible to display and build the Scratch Project into your Delphi Project.
I wish to make a small game in Scratch and then use the game within my Delphi Application without the need of the Scratch IDE. Perhaps a 3rd party delphi tool or component or something that can help me achieve this would also be nice.
Is this possible?
How can this be done?
It's possible, like everything, but it's not been done AFAIK, which means it's going to be hard work.
You have a few choices:
Scratch is normally embedded within web sites as a Flash object. If
you can embed Flash media, that is a solution.
Some Scratch-inspired systems like BYOB export to exe. You could look into how they do that to use your project (Scratch and BYOB
are compatible enough to load your project and export it after
minor changes)
If you don't like these, then write your own Scratch interpreter for Delphi. Scratch sprites are objects, their behaviour is straightforward enough, the Scratch projects are easily parsed (it's XML), now - off you go!
I am assuming that you want to port a scratch program to .EXE.
If this is the case, then you can install BYOB.
After doing this, you can convert your scratch project to a BYOB project and load it into BYOB.
Then, go to Share->Compile this project, and it will generate a .EXE for you.
I'm having some kind of problem with my project that me and my friend is working on. When I try to open the project that I've been working on it gives me an error message saying that "one or more lines were too long and have been truncated" and thus I can't see my code or GUI. When my friend opens the project on his computer (The project is on dropbox so it's the same file) there's no problem at all. I've googled but couldn't find anything. I just did a repair of RAD Studio but no luck. We have 2 forms and a unit that we use, the unit and the mainform isn't working for me but the second form is no problem.
Thanks!
Make a copy of your project directory.
Search your harddisk for XXXX.pas and XXXX.dfm
Hopefully there will be some temperary files that match - like "mylostform.dfm.~1307~" . copy the newest to your project directory, and rename them to "mylostform.dfm" and "mylostform.pas".
Kind regards,

From the comments, you have Dropbox, and the Restore functionality is available, but using it would cost you a week's worth of work.
If I was in that situation, here's what I would do:
Copy the current file to somewhere else (My Documents, for example).
Use Dropbox Restore to get the old version that works.
Make a copy of this, because you're going to be modifying it
Ensure that you can open it in the IDE.
Use Beyond Compare to open the two files side-by-side. (If you don't have this, you really should!)
If they're completely different from each other, you have a serious problem. If not, you'll see the changes you've made. Start copying changes one at a time, and after each change, save and try to open it in the IDE.
At some point, you won't be able to. That's where your problem lies. Now you can fix it!
So I really cant understand how this work but late me explain. First, just in case you need it, I am running Ubuntu 12.04 64-bit on a laptop.
As a building tool am using CMake. I want to load in to my project OpenCV, MRPT (http://www.mrpt.org/) and libfreenect. All of them have a "source code". What I don't understand is when they say "build from source". How to I make a project with all of them?
Do I need to build each one individually and with some way but then in my project OR do I down load the source code and build them all together at ones? As you can see I'm really confused what I have to do... do I run the CMakeList.txt from each source code and the run one CMakeList.txt that has all the other CMakeList.txt?
In fewer world, if I want to build from source, two or more libraries, how do I do that?
I would like a general answer (how this "build from source" works) and an answer specifically on the the ones I mentioned (CMake, OpenCV, MRPT, libfreenect). I hope I made clear what I don't really understand.
It depends of the 'master' project. In general in the c/c++ universe your project must know how to invoke the build process of each subproject/library OR your project needs to know how to include&link the results after building each external project yourself.
You can also mix the two approaches if needed but I think it cleaner to try to use one if possible.
In the first case if all the subprojects offer cmake building files (CMakeLists.txt) you may try to add_subdirectory() each and see if there are any conflicts. For example google test can be easily included this way and it gives your project some global variables that easy linking later.
Alternatively or if the above approach gives problems or the sub project doesn't provide CMakeLists.txt you can use ExternalProject_add(). It takes more work and you have to handle includes/linking configurations with your project manually but it makes the subproject more independent. For example if there are conflicting targets with your project or the subproject doesn't provide CMakeLists.txt.
The last approach involves building and installing the sub projects separately, using configuration variables in your project to point the includes/libraries paths of the sub project. Check CMake:How To Find Libraries for details.
We create via "Tools | Options | Environment Variables" Variables like that:
$(Sources) = D:\Sources\Delphi
$(OurLib) = $(Sources)\OurLib\Src
$(OurApp1) = $(Sources)\Applications\App1\3.x
$(ThirdParty) = $(Sources)\ThirdPartyComponents
We use these Variables in the project search path like that:
($OurApp1)\Src\Core;($OurApp1)\Src\GUI;($OurApp1)\Src\Plugins;$(ThirdParty)\JVCL
But this is broken (meanwhile fixed) since Delphi 2009 as these variables are not evaluated completely anymore (see QC #73276). So the files in the directories are not found by the compiler. A workaround: Use only complete directories in the environment variables.
We use this approach because on all developer machines and the build servers the files can be found and we only have to point $(Sources) to the right place.
We don't have anything in our global library path (except the Delphi defaults), because that wouldn't be in the version control and isn't reflected on other developers or build machines.
One problem is: If one unit in $(OurLib) decides to include another new unit maybe in a new path, all projects break because they don't find this new unit. Then we have to go through all projects and add the search path. (BTW: I really hate the search path editor...wouldn't be a simple memo field much better to edit than this replace/add/delete logic?)
Another thing we do is not adding many units to our project. Especially everything from $(OurLib), but we often have units like plugins which add functionality only by including them. For different editions of our products, we want to include different units. As Delphi always messes up $IFDEFs in the uses clause in the .dpr we help us by including units named like "IncludePlugins" which then include the units depending on IFDEFs.
But not including units in the project makes navigating to a pain. The units don't appear in the project, they are not found by Ctrl+12 (Show Units), they are not shown in code completion etc.
Has anybody a better way to cope with these problems?
We use only relative paths, any libraries are always below the libs subdirectory while the project source code resides in the src subdir. So our search paths always look like:
..\libs\library1;..\libs\library2\common;
etc.
All libraries are added as svn:external to each project, so checking out the project will automatically check out the libraries as well and the search path will always point to the correct version of the library for that project.
Not perfect, but it works most of the time.
I have to agree about the search path editor, it is even worse for relative paths because you must not use the "..." buttons otherwise Delphi will insert an absolute path.
We use standard drive mappings.
Our current project is always on W: regardless if it is a network drive or a substitute.
This works great.
When you need to work on a different project, swap the W: and you can continue.
You can copy the search path out to an editor, modify it and then copy it back.
Your search path is much too big. It should contain only the things you want Delphi to recompile with your project. You don't really want to recompile the Jedi VCL every day, do you?
I create a single directory where all compiled units go. Say, C:\dcu. Specify that as the "unit output directory" in all packages. My "search path," then, is always just this:
$(Delphi)\Lib;C:\dcu
The compiler finds everything it needs, and it never finds any source code. The only source code it ever sees is in the files that directly belong to whatever project I'm compiling. The project's own source directories don't need to be on the search path because all of those files are already direct members of the project. The compiler knows exactly where they are.
For me, all a project's source files go in a single directory. If you want separate directories for different parts, like Core and GUI, then I would put those in separate packages so I could work on them and compile them separately. Even if the final program doesn't use the resultant BPLs, packages are still a good way of segmenting your project and defining dependencies.
When compiling units for one project doesn't automatically compile units for all the other projects, you're forced to change active projects. It takes a moment of your time, but it also serves as a mental reminder that you're "changing hats," too.
Although you're producing just one product, that doesn't mean you should have just one project in Delphi. You should have at least one project for each executable module (EXE, DLL, BPL) in your product. Use project groups to manage multiple projects in a single IDE session. No unit should be a member of more than one project.
I don't understand your part about plug-ins and different editions of your project. When you say "plug-in," I assume you're talking about separate executable modules, like DLLs or packages, that the customer can choose to include or not. Couldn't you turn your different editions' features into plug-in modules that simply don't include in the lesser editions? Then you don't have to worry about conditional compilation of your project; just have several different installer packagers that grab different sets of plug-ins.
I have always found it odd that this has never been addressed adequately. I suggested recently to David I that Delphi should allow the user to set up some sort of preferred development structure and that third party library publishers could be made aware of this so that they could automatically adjust their installers to install correctly in the preferred development framework. If the preferred development structure was stored in an XML file or similar, then, it could be copied from one computer to another on a development team.
As an alternative, it could make an interesting project to create a Delphi application that would allow a user to "refactor" their library installation in a high level way. You specify which folders on your system contain source or compiled components or whatever and where you want to keep source files or compiled units, hit Go and your system gets rearranged for you, while updating your Delphi environment so that when you start Delphi, it finds everything it should.
I've just recently discovered a way to have project specific environment variables in delphi builds using XE6, it's not quite as good as a full blown #define like in C but at least I can now have consistent search paths across multiple projects and create some shared option sets.
What I've done is setup environment variables in the same manner as the original poster and then override them in the dproj or optionset.
