Code::Blocks Question

Question
I plan to make the plugins pack, however, for the base install of Code::Blocks, should I remove all plugins, or install the plugins that are checked by default in the standard Code::Blocks installer?

Previous Issue Solved
I'm still working on trying to make Code::Blocks portable, and I'm running into a very unusual issue.

when I use the code to redirect APPDATA to the /Data/settings directory, it only works if I have a message box pop up to display the new contents of APPDATA. I've tried setting a Sleep time from 200 up to 2000 and it just doesn't work, but if i use the messagebox, it does.

When it works correctly, the folder /Application Data/codeblocks is created under Data/settings, and the settings are saved in that location. The files are created on launch of CodeBlocks, and then modified as things change.

When it doesn't work, no settings files are created until codeblocks is closed, and then it only creates a "default.conf" on the root of the drive.

RE: APPDATA

Well you can't redirect the APPDATA environment variable without admin rights, not to mention there are a host of other ways apps refer to it. Your only other choice is to move the data it writes there between APPDATA & Data\Settings similarly to how you move settings to/from PROGRAMDIRECTORY when an app expects its data in the directory it runs from. Since APPDATA is not a controlled setting you'll also have to check to see if data from a non-portable install is there and rename it before moving in the portable data, similar to how registry entries are now done. I don't know an existing launcher that does it, but lots of them do both of these things which shouldn't be hard to adapt.

I figured moving would be the way to go. I could rename an existing directory if it exists, then move the portable settings in...and then reverse the process, just like the registry stuff is handled

Did You Try This?

Did you see if this variable works?

System::Call 'Kernel32::SetEnvironmentVariableA(t, t) i("APPDATA", "$SETTINGSDIRECTORY").r0'

Try popping that in somewhere before the launch, and see if it works.

admin rights

Doing this requires admin rights, as I mentioned in my first post. That's right, MS coded in an explicit hack to prevent you from changing this one environment variable.

Hmm..

Good question. It does appear to work in PokerTH using dropmyrights. It's possible my source was wrong. I googled it when doing GnuCash and came across several sites claiming that it required admin rights to change. More than likely the application they thought used it was using another method like CSIDL_APPDATA or '%USERPROFILE%/Application Data'. Try it and see Zach.. maybe you'll luck out and Code::Blocks uses the real variable. Smile

your source was wrong because I doubt John would use this method without ensuring that it works even on guest accounts.

Programmers are lazy

We tend to use the easiest method to accomplish something, even if it's not the recommended way (in this case, CSIDL_APPDATA is the "right way").

Oh, %userprofile%\Application Data doesn't work under Vista, at least not with UAC enabled. Typing that into the Run dialog or explorer's address bar results in an access denied error. Use %appdata% instead.

I just tried it as a limited user and had no problem.

You would certainly need Admin privileges to change the registry setting or wherever the API call gets its data from, but so far I'm not seeing a problem setting %APPDATA%.

It is likely the browser is broken, not the page. If it is the page, the admins would want to know.

Can you say what browser (and version) is doing that?

The whole page loaded, yes. Browser is Firefox Portable 3.0 Beta 4, and I can confirm the problem doesn't exist in IE7 or Firefox 2.0. So indeed, it looks like I discovered a bug in FF3. Too bad I can't report it as I don't know what the conditions are to reproduce it...

This code::blocks forum link references some relevant information. Maybe all you need to do is figure out how to make default.conf work for you. That with your registry settings that you have already identified may fix this bad boy.

And this link. And this here linky.

You're Welcome.

I have been eager for this one as well, but have not had the time to put it through the paces. My home computer is on the blink, and I don't like to install too much on my work computer. I already have MinGW, msys, cmake, and gnuwin32 on my portable drive in the PortableApps\CommonFiles\ folder. But having an IDE would be beneficial for my poor weak mind. Biggrin I look forward to your work on this, and maybe I can help down the line. Cheers!

Try a cmd shell

My suggestion would be to put an execwait right after you set it and run a cmd shell so you can check the environment variables manually. If it still doesn't work after that and the variable is set right then it's probably using some other method of getting to the Application Data folder (USERPROFILE, registry, etc).

The only thing I can think of why the MessageBox would have any effect is perhaps it causes windows to sync the APPDATA variable with whatever method the program is using to access it besides the variable? I'm reaching here, it's definitely a strange one...

EDIT:

ISSUE SOLVED Biggrin CodeBlocks reads the USERPROFILE variable, not APPDATA, so I made that change...still didn't work...then I created an Application Data director under /Data/settings and it works...now for adding in the stuff to update all of the config files to use relative paths, or at least be able to update the drive letter.

Well I ran into some issues because Code::Blocks looks at the %USERPROFILE% environment variable, but stores it's settings under %APPDATA%, a subfolder of USERPROFILE. However, the path to APPDATA is handled differently in Win2K + XP vs. Vista. I have to write in some code to check what Windows version is in use, and have it handle redirecting the settings in a specific way for pre-vista machines and for vista machines.

SHGetFolderPath

I knew someone eventually would run into this problem. Why don't you try this? This is the 'MS proper' method for retrieving special folder paths, and should work regardless of OS. It's why I wrote it -

clsid

it's probably using CLSID to get the path to appdata which uses %USERPROFILE% in the path. I've run into this problem with a couple of apps. I sucessfully did what you're trying to do with having it switch and work right under xp or vista and having it change back when switching pcs but then i realized it still wouldn't work right because PCs in other languages have different folder names also. i think i can get it working now that i just thought of something, but in my opinion you should just have it copy the files over to the APPDATA env variable and copy back for a preemptive release and when either you or i get the userprofile stuff worked out you can update it to Dev Test 2 or something

From the faq

Q: How do I make Code::Blocks portable?

* run / configure C::B as usual

Note: Code::Blocks will create a default.conf file that usually is placed into: "C:\Documents and Settings\[your_user_name]\Application Data\codeblocks" (or %APPDATA%) on Windows or your usual home folder ("~/") under Linux.

* place this default.conf file into the directory where the codeblocks binary is
* remove the default.conf file from %APPDATA% / home folder respectively
* just run C::B from within the C::B path and/or via script / link...

Note: Don't forget to remove all bad hacks you might have done previously that modify %USERPROFILE% and/or %APPDATA% on Windows.

Note: If C::B does not find default.conf (it's config) within the %APPDATA% / home folder it looks within the C::B directory (the one where the C::B executable is) next. If there is no config file, too it will be created in the %APPDATA% / home folder. So just make sure you are doing the right thing and C::B is portable just fine.

BTW: This does probably not apply for any other config file(s) where not C::B is the maintainer but e.g. plugins. The main config file just works like that.

Hope that is of some use. I fancied having a go over a year ago on this but never had the opportunity to start on it. You could look at recompiling it yourself from source.

I've seen that. I know that works, but I also read that some plug-ins havent been updated lately and won't redirect their settings properly. I may end up just doing a release that uses the method you mentioned anyway.

When I asked in the Code::Blocks forums, their responses weren't too friendly...the best i got was a link to the same info you copied here, and a "it's up to the individual plug-in developers to make sure their plug-ins work correctly"

I was so sick of my University computers that I bought myself a laptop to run Code::Blocks but still would love to see Code::Blocks become a portable reality. I got to a crappy poor University. Yes, an University, not community college or Junior College. The country that I live in is so crappy.

Too bad. Something that requires that program is not installed on host computers is not really portable. I wonder why do they check appdata before own directory?

They actually do check their own directory first, it's the plugins that may or may not be an issue. When I asked about it in the C::B forums, the answer I got was essentially "if you use the method described on our wiki, C::B will be fully portable, but it is up to the plugin developers to make sure they wrote their plugins in the correct way so it checks the CodeBlocks folder first" that comment even held true for the optional plugins that come in the full code:blocks package :-|

Yeah I could. The issue is ensuring that all the optional plugins work correctly. If the user adds no plugins, simply moving the config file between Data\settings\ and App\CodeBlocks would work just fine, but there is no guarantee that all the plugins will check the CodeBlocks directory for the config file first.

When I asked about this in the CodeBlocks forums, they basically said "sorry, we don't know, it's up to the individual plug-in developers to make sure they follow how CB works. (Look in CB dir for config, and if not there, create settings in APPDATA)"

Zach, I disagree with your conclusion.

Why would you have to test every plug-in when you are portabilising the main application? If there is a plug-in you are putting with it, it makes sense; but this is like asking John to test every Firefox, Thunderbird, The Gimp, or OOo plug-in before saying the app is portable.
Some plug-ins break portability. According to the developers, the plug-ins are supposed to follow a proper behavior. Of course they don't know which ones don't, mainly because it doesn't concern them as much as it does us. If it is needed, a plug-in compatibility page could be set up and linked to from the installer or the help page.
If someone comes across a compatibility issue, it could be addressed with that specific plug-in developer and indicated on the page.

Just some thoughts. Back to sleep now. Biggrin

Answers...

I keep MinGW in my CommonFiles folder "\PortableApps\CommonFiles\MinGW", I also use Digital Mars compiler and a couple of others. (I am mainly testing the waters, no real coding experience but no access to the same resources everywhere either. Hence the portability.)

A portable MinGW installer would be nice, but probably should be separate.

I like the idea of a plug-ins pack. But again, if necessary, we can install our own, especially if it is straight forward.

mingw separate

I think Mingw should be separate, and in commonfiles, similar to how the java portabilizer works. I use mingw for several different things, and all of them using one install in commonfiles keeps things more sane. Preferably code::blocks would be pre-configured to look in commonfiles\mingw for the mingw files.

If you do go this route it would be nifty if you provided a separate download for a mingw installer that installed to commonfiles like the java portabilizer! Smile I wouldn't hold up the code::blocks test for this, though, since "portabilizing" mingw is as simple as copying an unzipped mingw directory to commonfiles.

What Happened?

I would really like to see a portable version of this out, and i have my own idea (or course) for how to solve the problem. you can use the ProcessStartInfo Method (http://msdn.microsoft.com/en-us/library/system.diagnostics.processstarti...) in order to set the environment variables for the specific application that you are launching.

Hope to see one soon!
