Hello! At some times ago. this list have a discussion of an portable version of the Lazarus. Where I can download this version?

The Lazarus is portable by default. I use it in a external HD without problems. But you have to initialize Lazarus with --pcp parameter.

That doesn't solve the driveletter changing. If I understood everything correctly, for that you also need to rewrite the fpc.cfg and override lazarus dir using the (0.9.30+) --lazarus-dir parameter

Correct, and a simple application launcher (small utility appl) can do this quite nicely. I even think startlaz should be modified to support this - it should be quite handy for some developers, and makes startlaz a bit more useful.

I have done this before with a small launcher app, but don't use it any more...Just looked, I can't find the code for it either, sorry. What I did was something like this: The launcher app picked up the drive letter (and path) where lazarus executable lives (they are both in the same directory), then sets an environment variable before launching the lazarus executable. The fpc.cfg uses the environment variable to correctly specify the unit paths. Actually I can't remember if it was an environment variables or a small auto generated text file that is included via #INCLUDE inside fpc.cfg. Anyway, one of them worked.

Yes, the fpc.cfg is not portable. And fpc has some fixed defaults, which IMO are not very helpful. At least I don't know any Linux or Mac where these defaults work. But I do know some systems with left overs where these defaults create misleading error messages.

and override lazarus dir using the (0.9.30+) --lazarus-dir parameter

The lazarus directory is a value in the configs. Maybe this directory can be saved relative to the primary config directory, if both share one parent directory.

Aha! But I always use the same drive letter! ;-)

but i not...

Could i use relative path in fpc.cfg?

I did more simpler:
One script that verify the driver letter and starts Lazarus with --pcp.

Marcos Douglas

I use on Windows with sucess. Not need to modify de fpc.cfg in this case.

Why not?
Choose a driver letter that nobody uses. But you always can override the paths any time...

I think not.

We can create a launcher. Is more easy to use. Who can help me?

A launcher is easier then a script?
See my BAT script:

@echo off
set mypath=W:\freepascal
set mylaz=%mypath%\ide\laz\0.9.30
cd \
if /i %cd% equ W:\ (
cd %mylaz%
start lazarus --pcp=%mypath%\ide\laz\config --lazarus-dir W:\md\dev\freepascal\ide\laz\0.9.30\
) else (
echo "invalid driver"
pause
)

The problem is not Lazarus, but rather fpc's fpc.cfg file. Imagine the case where Lazarus and FPC is installed on a USB stick.

For me is the same thing :D .

'cos sometimes i use my pendrive on PCs that i doesn't rights to change drive letter...

I wanna use it on my pendrive to build applications on any windows, updating only one lazarus installation when it's necessary...

2011/6/17 William Oliveira Ferreira :

The only problem is fpc.cfg.
But, if you do not permission to change the driver letter, just replace paths in fpc.cfg. It is boring, I know, but works.

but could i use relative paths or they must be absolute? ________________________________

I have a
http://free-pascal-lazarus.989080.n3.nabble.com/file/n3076763/LazarusPortable.zip portable launcher source code extracted and modified from original version by Juan A Melendez (WARNING: kinda i386-win32 centric, please modify as necessary). Put this launcher in a directory, inside the directory create App and Data folder. Put lazarus folder under App, fpc under lazarus, without any version (e.g. the path to fpc.exe should be fpc\bin\i386-win32 instead of fpc\2.4.2\bin\i386-win32 or similar). Next, copy lazarus folder from %USERPROFILE%\Local Settings\Application Data to Data folder. Done. Just remember to always execute from the portable launcher and you'll be OK.

I think just absolute.

At least FPC trunk allows to use environment variables in fpc.cfg by surrouding them with dollar signs.

If you are on Windows, note also CodeTyphoon:

I am using it right now with moderate success for teaching children.

Very nice feature. It will come in very handy, and simplify the fpc.cfg, compare to using #INCLUDE

Explain?!?
