Hello,

after installing the new SDK and rebooting a have no gcc in path.
I installed the new SDK to Sys:Developement (the default path).
There enough disk space left on my SFS partition.

Code:
```
System:Development> GCCSelect 7
Switching default gcc links to the gcc 7 package
System:Development> gcc --version
gcc: Unbekannter Befehl
System:Development> which gcc
```
Sys:Prefs/Env-Archive/MorphOSSDK pintes to "SYS:Development/"

Are any other scripts have influence to the SDK setup?

Yeah sorry, I should have removed this script long ago. You should set CC to the compiler of your choice.

So am I right in guessing that noobs like me are going to need some assistance in setting up the new SDK and choosing which GCC compiler version to download, setup, and use, so that I can get back to learning the basics of C/C++ programming on MorphOS? I'll be using Hollywood programming language most of the time, but would like to also get back to slowly learning the basics of C/C++ programming, or at least have it set up on my MorphOS systems, so I can show the SDK and newer GCC compiler versions supported, to other users at the AmiWest Show.

Edit: I'm assuming that the SDK and the different versions of GCC are downloaded and installed separately. Noobs like me need advice on which version of GCC to install, and why that version should be used. Unless it is unstable, or does not produce code that is best optimized for MorphOS, I would think that the latest version of GCC would probably be the proper one to install, yes?

The SDK contains all the GCC 2,5,7,8 and 9. You should refer to them as ppc-morphos-gcc-X. Alternatively you can make 'gcc' point to one of those with the gccselect script.

The recommended way to compile projects is to set that up in FlowStudio OR write a makefile, where you should absolutely set CC to ppc-morphos-gcc-X

So,

so in the end, that's what did and I unerdstand so far:
1. Removewd SDK from Sys:Development
2. Removed file MorphOSSDK from Sys:Prefs/Env-Archive
3. Reboot
4. Did a clean install of the SDK to Work:Tools/Development
5. Reboot

- MorphOSSDK points to correct path
- PATH says:
Code:


Work:Tools/Development> path
Aktuelles_Verzeichnis
System:MorphOS/C
System:C
System:Utilities
System:S
System:MorphOS/S
C:

There is no gg:bin, so

Code:


Work:Tools/Development> gcc
gcc: Unbekannter Befehl

must fail!

Going to gg:bin
Code:


Work:Tools/Development/gg/bin> ppc-morphos-g++  --version
2.95.3

so the link points to version 2.95.3 at default

Code:


Work:Tools/Development> GCCSelect 5
Switching default gcc links to the gcc 5 package
Work:Tools/Development> gg:bin
Work:Tools/Development/gg/bin> ppc-morphos-g++ --version
ppc-morphos-g++ (GCC/MorphOS) 5.5.0
Copyright (C) 2015 Free Software Foundation, Inc.

GccSelect just sets ppc-morphos-gccc|g++|cpp but NOT gcc or g++

So I have to create these links on my own.

Code:


Ram Disk:> path add gg:bin
Ram Disk:> path
Aktuelles_Verzeichnis
System:MorphOS/C
System:C
System:Utilities
System:S
System:MorphOS/S
Work:Tools/Development/gg/bin
C:
Ram Disk:> ppc-morphos-g++ --version
ppc-morphos-g++ (GCC/MorphOS) 5.5.0
Copyright (C) 2015 Free Software Foundation, Inc.

warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Ram Disk:>

After adding gg:bin to path, I have all the sdk tools in path.

Which is quiet helpful if you want to use other tools like git from the SDK
Code:


Ram Disk:> which git
Work:Tools/Development/gg/bin/git

BTW the env variables are also wrong:

Code:


Ram Disk:> set
RC                       0
Result2                  0
_mchar                   &&
_pchar                   |

better:

Code:


Work:Tools/Development> set
CC                       gcc
CCC                      ppc-morphos-gcc
CFLAGS                   -ISDL/
CXX                      ppc-morphos-g++
CXXFLAGS                 -noixemul
LIBS                     -lSDL
RC                       0
Result2                  0
VIMRUNTIME               vim:
_mchar                   &&
_pchar                   |

So to sum it up:
1. add gg:bin to your path
2. create links like gcc, g++, ...
3. set your env variables on your own

I don't know if these are only problems on my machine.
But I really don't know what I am doing wrong at installation?
If these probleme also exist on all other machines, I think the SDK should be fixed, because
after installation there should be working env.

Just recognized that the Startup script in SDK: is not executable!
Is this correct?
If I look into Mossys:s/startup-sequence I can find the following line:
Execute >NIL: SDK:Startup

Strange,
after setting the Startup script executable and one more reboot, everything seems to be fine.
Now there also the links g++, gcc, ...

Now I am totally confused ...

Almost sounds as if you tried to use the SDK without rebooting after installing it. There's a part of the setup that gets ran during first reboot after you've installed the SDK.

Which file system are you using by the way?

It doesn't have to have the S or E flags if you launch it via Execute.

In latest 3.14 morphos sdk GCCSelect is removed and now by default gcc version is 9.

I'd like to know why was removed this feature.
It was nice to see different code generation and/or sources compatibility between various versions of gcc.

Anyway gcc 9 it ok too

There is no reason for GCCSelect. Use Flow Studio's Project functionality, CC for configuring or explicitly pick ppc-morphos-gcc-X in a makefile or when building from command line.
