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.

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.

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.
