Hi,
After I updated Keil from uVersion 5.37.0 to 5.40.0, I got the following error:
Build started: Project: FPIE-4K*** Using Compiler 'V5.06 update 2 (build 183)', folder: 'C:\Keil_v5\ARM\ARMCC\Bin'Build target 'FPIE'compiling Exec.c...C:\Keil_v5\ARM\CMSIS\6.1.0\CMSIS\Core\Include\cmsis_compiler.h(287): error: #35: #error directive: Unknown compiler. #error Unknown compiler.Exec\Exec.c: 0 warnings, 1 errorcompiling System.c...C:\Keil_v5\ARM\CMSIS\6.1.0\CMSIS\Core\Include\cmsis_compiler.h(287): error: #35: #error directive: Unknown compiler. #error Unknown compiler.Control\System.c: 0 warnings, 1 error
I'm compiling the same project (FPIE-4K) with 5.40.0 as I did with 5.37.0.
Any suggestion on the compile error?
Thanks
David
Hi Ronan,
Thank you for the response to my question.
I was using Keil MDK 5.37 for a couple of year without any issue.
I recently updated Keil to 5.40. After that, when I compiled some old projects (that were developed under Keil 5.37), I got these errors.
It seems Keil 5.40 installer created a new folder, C:\Keil_v5\ARM\CMSIS\6.1.0, and Keil 5.40 forced the compiler to use the new folder .
If I selected ‘Use default compiler version 6’ under ARM Compiler / Option For Target in Keil/uVision IDE, I got a lot more compile errors.
I have both ARM Compiler 5 and 6 in uVision IDE.
I felt somehow Keil 5.40 installer mixes ARM Compiler 5 and 6.
How do I go back to use ARM Compiler 5?
Arm Compiler 5 is no longer installed by default, but can be downloaded and installed separately. See instructions at:
https://developer.arm.com/documentation/ka005073
To change the version of the pack(s) used, open Manage Run Time Environment, and click on Select Packs.
Then deselect "use latest versions", and you can select particular versions.
I do recommend you migrate to the latest software and compiler over time. Arm Compiler 5 is no longer supported or maintained.
I followed your post (due to a legacy code issue tat was compiled against Arm Compiler 5) but the option to change the CMSIS version is no longer available. I either have "latest - fixed -exclude" options but no way to change the version.
When you expand the tree you will see all installed versions
I just changed to version 5 from version 6, now compiling fine from Ronan's screenshot, just toggle to fixed, expanded the tree and checked the box for version 5.
Cheers.
