Opening project in FC10 in FC11!

[jgu1]

Hi Team!

It hurt me, its´me again, sorry

I am testing some of my project I have made in FC10 now in FC11, (Steve promised me that I could open all FC10 project from FC10 in FC11, they working in FC10)

During compiling a one of my program in FC11 I suddently discover this red line:
C:\ProgramData\MatrixTSL\FlowcodeV11\CAL\ESP\ESP_CAL_Float.c:91:6: warning: conflicting types for built-in function '__builtin_isinf_sign' [-Wbuiltin-declaration-mismatch] ?

In another project with a ST7796 test program opened in FC11 the size of font have change, huge and I can´t change them and the update of the display is slowly vs if I use FC10?


It worries me that after only two tests there are errors, I hope I don't have to spend many hours on bugs again.

Hi Jorgen.
Steve is correct most projects that work in FC10 sould also work in FC11
There was a decision for FC11 to have the total fonts reduced and arrange in a nice neat order.
That means for FC11 users some of the fonts that were selected with FC10 will not be available in FC11
You would need to choose another font.

There is a way of restoring the old FC10 fonts if you really want to do that but I would recommend keeping the FC11 set of fonts.
1. Rename the fonts folder within %ProgramData%\MatrixTSL\FlowcodeV11\Components\ to anything e.g. fonts ORG
The directory will be hidden, so copy and paste within windows explorer.

2. Copy the fonts folder within %ProgramData%\MatrixTSL\FlowcodeV10\Components\
and paste it within %ProgramData%\MatrixTSL\FlowcodeV11\Components\ folder.

3. Reload your project.

I have suggested to rename the original FC11 fonts folder, so you can restore them if you wanted to.

Hi Martin!
Thank´s

From my question:

Steve: Yes - v10 projects should open in v11 without problem.

I was a bit uncertain about upgrading, as I’ve experienced similar issues in the past when moving to a newer version.
It was actually Steve’s assurance that convinced me to upgrade — that I would be able to continue in FC11 from where FC10 left off.
Now I find myself having to make extra adjustments again just to get things working, or otherwise, continue my projects in FC10.
I’m a little disappointed about that, and had I known in advance, I probably wouldn’t have upgraded.

And what about this, comming up even if I try to start a new project in red: C:\ProgramData\MatrixTSL\FlowcodeV11\CAL\ESP\ESP_CAL_Float.c:91:6: warning: conflicting types for built-in function '__builtin_isinf_sign' [-Wbuiltin-declaration-mismatch] ?

I don’t mean to sound negative or as a complainer, but the upgrade was quite a significant cost for me.

Hello Jorgen,

Sorry, I was not aware of the v11-specific changes to the fonts used in a particular component in Flowcode.

And I'm sorry you are disappointed and feel my original answer was misleading. My original text was "Yes - v10 projects should open in v11 without problem." There were lots of questions and in hindsight my answers were too brief and not specific enough. I used the word "should" rather than "will" because there are always potential issues that can occur when software is upgraded. I will change the text in that post so that anyone reading it will understand there is no guarantee that a project created in v10 will behave 100% the same in v11.

It sounds like you would prefer to stay with v10 and I totally understand. It is never our intention to force users to upgrade. We can probably issue a refund and kill your code for v11 so you can continue to work with v10. Tell me if you would like me to sort this out for you and I will do it today.

It is probably useful to add my extra explanation here so that it is more visible. This is what I have just added to that original post when you asked "Can I open and continue project wich I have started in FC10?":

Just to expand on this, while most v10 projects will open and function just fine in v11, there will occasionally be cases where this is not the case. There are many changes in the core product between v10 and v11 and we have done our best to test backwards compatibility, we cannot individually test everyone's v10 projects and identify all issues that may arise. And although the vast majority of v11 components are direct copies of v10 code, there may be some changes that I am personally not aware of and so no-one should take my original answer above as a guarantee that a v10 project will work 100% in v11 without some modest changes. It is always best to try v11 first, and using the free version of v11 should in many cases highlight where there may be issues. As normal, we will provide help and advice on this forum for any v10 project that is not working the same in v11.

During compiling a one of my program in FC11 I suddently discover this red line:
C:\ProgramData\MatrixTSL\FlowcodeV11\CAL\ESP\ESP_CAL_Float.c:91:6: warning: conflicting types for built-in function '__builtin_isinf_sign' [-Wbuiltin-declaration-mismatch] ?

This is a warning and might also be present when you compile the project in v10. In v11, we have added colour highlighting to make it more obvious where lines are showing warnings and errors.

If the project is behaving differently in v10 and v11, please post your 2 projects and we can try to determine the cause of the problem.

Hi Steve!

Thank you very much for your reply and for the very fair offer.
I fully understand that there might be some challenges in the beginning, but I must admit I felt a bit disappointed when I opened one of my projects and already saw during the first test that it didn’t work as expected.
I immediately thought — will I now have to adjust all my projects for FC11? That’s why I asked.

As you know, I’ve been using Flowcode for many years with the professional versions and have always tried to be helpful whenever issues appeared, spending many hours testing and reporting bugs.

I am, and have always been, very happy with Flowcode, and I was genuinely looking forward to continuing — especially now with the possibility of even more, in the future and bennefits ,components and features in FC11.

If it’s okay with you and the Matrix team, I’d like to give FC11 a proper try and test Martin’s suggestion.
If you agree, I’ll continue working with FC11 for 2–3 weeks, and if I encounter too many bugs related to FC10 projects, I’d like to kindly accept your offer of a refund.
Would that be an acceptable solution?

Hi Jorgen.
You should not need to sort out any bugs/issues.
If you have any issues with conversions from FC10 to FC11 then we will sort them out for you.
This will apply to anyone.

[jgu1]

Ok Martin, Tell Steve that I continue with FC11 and he may not delete my licence.

Thank´s

Hi Jorgen (and this applies to all users of this forum),

Firstly I just want to add something to what Martin has just said because I don't want this to be misinterpreted:

If you have any issues with conversions from FC10 to FC11 then we will sort them out for you.

We will certainly investigate and try to sort them out, but we cannot make any guarantee that we will be successful. If a solution cannot be found in a reasonable time then your project may need to stay on v10. If the v11 project has converged significantly from the original v10 project, then you may be best going back to the original v10 project. If the project relies on hardware that we have no easy access to then solving the problem could be too difficult for us.

I'm also very aware that vague comments on this forum by Matrix staff members (like my previous comment that a v10 project "should" be ok in v11) can be taken to mean more than they are. However, these forums are places where we can share insights and advice on getting Flowcode projects working. Nothing we (or any other users) post on this forum should be taken as a legal guarantee.
