Reinstalled 53.20.
Now when i try to compile a mui program shell says:
error proto/muimaster.h no such file or directory...
error libraries/mui.h no such file or directory...
error proto/alib.h no such file...
...
What can i do??

thk you for your answers!
i downloaded again sdk but there's the same problem.
(I upgraded the old installation)
I disabled perl installation and it worked fine!
Strange thing is when i double click on sdk installer it says something like "folder @#à@à is not empty. would you like to continue?". It seems the name is made by trashed characters. I answer yes and after a little if there's perl it gives me the error message.
How can i disable write protection of a folder and all of its children?

I'm trying to reinstall sdk but when i try, it says: openinf of file failed in archive perl-5.8.5.
Any clue?

thank you!!!

I discovered it happens if I use os4depot version.
If I use aminet (os3) ones, it works good!

Hi! Just Installed muibuilder from os4depot, but when i try to extract the code, shell says: "cant open muibuilder library"
Previously it said: "unknown command .../modules/gencodec" now installed gencodec and there's no more errors).
Any clue?
Thanx!

Hi! Will "past architectures" like sam440 be abandoned with 4.2?
Thk you (and a Very Happy Easter!)

hi! i unplugged it, replugged it, mounted new fdrive (teac fd-235hg) and it all worked!
thank you!

thank you!!! it worked:)

if i try your command list, at "cmake ..", shell answers it can't find cmake.
So i looked in the forum and add path as explained in another topic.
Now when i type cmake .. the answer is: cmake erros: could not modules. i added modules folder to bin in amicygnix. now
when i type "cmake .." ita appears a grim reaper window with guru meditation talking about dsi error, redzone damaged and guard area hit...

Hi! I'm trying to build a program with cmake.
When i use cmake, shell tells me:
cmake .. -G "Unix Makefiles"
CMake Error: CMake was unable to find a build program corresponding to "Unix Makefiles". CMAKE_MAKE_PROGRAM is not set. You probably need to
select a different build tool.

Any clue?
Thx!

no way.
installed cw driver again, changed two floppy (one nilox and one alps electric) but nothing. on new drivers it says error on block 0, on old drivers "error 30"...

Hi! Surely a noob question!
I installed my catweasel mk4+ on my sam440 with latest drivers from retroreview.com
It didn't work because it said: reading error on block 0.
So i followed this thread to the point of copying dosdrivers in two suggested paths but now when i try to boot my os4.1 rev 5, it tries to do it from floppy but it doesn't go on...
How can i do?

edit:
i disconnected catweasel but os doesn't boot.
formatting...

Thank you!
I'll give it a try tonight!!:)

Let's see if i've understood something:D:D

When I launch an application Workbench passes to it a WBStartup structure.
In WBStartup there's another struct struct WBArg.
WBArg has two fields: "a lock" and a "name" of the selected icons (working as argument of the program).
So we can find all selected icons and work with them.
It even works with an AppMenuItem.
And this is a very good thing! (Congratulations for the wiki!!)

But if i would i.e. click a button of my app and have a list of all the selected icons in a drawer?
Does the window store a list of all selected icons in it?

ok! thank you!

How can i read the selected icons?
In Amiga Developer's Handbook i read about the SelectList, but how can i access it?
Thank you!!

@for all of you:
thank you for all the answers!!!!

thank you! solved with __USE_INLINE__!!
Now i'm compiling playsineeverywhere.c from lowlevel but it tells me it can't find: config.h, version.h and hookentry... I hope it's not some misconfiguration of my sdk..

First: Hi to all!!
I'm new to os4 programming (i've got a little experience in aros and morphos).
Where can i find some "tutorial" that introduces me to os4 coding?
I've compiled something in the last days and i found i've to use iexec and idos to use api.
Is there a way to avoid this? (i.e. i compiled ahi ppc os4 examples and they give me the same errors (implicit declaration of function...))?
Thank you!!
