Hello

I use FlowStudio with GCC5. However after release MorphOS 3.13 I decided to download new SDK (3.14) and switch to GCC9. Unfortunately when I try to compile my project with GCC9 I have message:

Code:

If I switch to GCC8, everything is ok, project is compiled and linked with success, executable file is ok.

Where is the problem? Makefile generated by FlowStudio uses mkdir but... it looks ok. Why if I use GCC8 everything is ok?

I noticed, if I set in Project Setings "g++-8", next to cycle gadget I see (shaded) "ppc-morphos-g++-8". If I set "g++-5", I see "ppc-morphos-g++-5", etc... However if I set "g++-9", the shaded label is empty.
It is strange because I have GG:bin/ppc-morphos-g++-9.

Your have to use only gcc and g++ command binary in flow studio

Will gcc-9 be used if I set in project settings gcc and g++?

I am not sure because in GG:bin/ I see:
ppc-morphos-gcc <link to ppc-morphos-gcc-2.95.3>
ppc-morphos-gcc-2.95.3 <file>
ppc-morphos-gcc-4 <link to ppc-morphos-gcc-4.4.5>
ppc-morphos-gcc-4.4.5 <file>
ppc-morphos-gcc-5 <file>
ppc-morphos-gcc-7 <file>
ppc-morphos-gcc-8 <file>
ppc-morphos-gcc-9 <file>

ppc-morphos-g++ also is link to ppc-morphos-g++-2.95.3

So gcc and g++ probably use gcc-2.95.3, not gcc-9.

type in a shell "gcc -v" and see to what version gcc is refered

Gcc —version, under mos 3.12 or better should be v9

Err, you've just hit a bug in Flow. It'll probably work OK if you re-create the project.

On a side note, I do NOT recommend using 'gcc' in your makefiles, etc. Always best to use the full name. Saves problems if you want to cross-compile your project or target different archs explicitly.

Hehe. Ok, I will recreate project. However I probably have to keep gcc8 because my code is not ready for gcc9. :) And I have strange message "unrecognized option '-MP'". I am not sure if gcc9 allows to force C++ standard (e.g. -std=c++11). This version of gcc works strange for me. :)

Ok, I will specify version of gcc/g++ in each project. :)

If I create new empty project, and select "gcc-9" and "g++-9" (in "Project Settings"), full name of gcc version also is not visible next to cycle button. So re-creating project doesn't help.

I am encountering the same mkdir issue as mentioned above whether it is a new or existing project and across various compiler selections.

Hi,

Yes, that's a confirmed bug in the latest FlowStudio release. I'm sorry but you will have to either pick the gcc option or set the compiler name manually to ppc-morphos-gcc-9. This has been fixed in the meanwhile but you will have to wait for the next MorphOS release for the update.

You could update the SDK and include the fixed FlowStudio. Then people don't have to wait for the next MOS release.

An SDK update is mostly ready. We might include a Flow Studio update in it for sure.

The only problem is that the machine I use to build the SDK is currently unusable - crashes when compiling :| I've replaced the PSU, the box passes ASD tests just fine and still... Guess either the mobo or CPU are faulty. I'll look into the SDK as soon as I can secure a new G5.

Well, let's see. To be honest, I don't really see the need for an emergency bugfix when one can just set the compiler manually in the string gadget for the time being.

Thanks for the clarification

IKE

No problem. If I know that update fixes the issue, I can wait. Thank you for support! Flow Studio rules! 😃👍

Hi all,

i can share FlowStudio fixed on MorphOS-Storage if necessary.

I have the latest SDK and still get the MKDIR error. What's the workaround until it's fixed?

You can use Custom compiler and type gcc. It will use gcc 9.

Still the same (from the first post, but exactly the same problem):
### Build Start ###
make: Entering directory `/Files/MDW/dev/MyProject'
mkdir: missing operand
Try 'mkdir --help' for more information.
make: *** [MKDIR_RELEASE] Error 1
make: Leaving directory `/Files/MDW/dev/MyProject'
### Build End ###

What's the operand that mkdir is missing?

and what about with: ppc-morphos-gcc-9 ?
I using it without problema.

Still the same. (Flags, Include paths and Definitions are empty.)

Compiling from console is of course working fine.

Just for the record
Code:
FlowStudio was using the first one

I don't know if you have already replaced your G5 yet, but I have a spare Dual 2.7GHz G5 I could donate, if needed. Are you still in Canada, or back across the "Pond"? Shipping to Europe would be too expensive, but to Canada, it wouldn't be prohibitive.
