Missing memcpy(), memset() and strlen()

Hi

I have just installed 4.10.4.2023061600.53564 and wanted to build an old Kinetis (Crossworks) project but it now fails with this version because the linker doesn't find memcpy(), memset() and strlen().

The project has its properties set to include standard libraries:
Is there some other setting that need to be adjusted for compatibility with new Crossworks versions so that the libraries are used?

Thanks in advance.

Regards

Mark

  I am also seeing this problem.  My CrossWorks version is 4.9.1.2022120900.52035.

  Hi All
  
  I have found that some old project do build but others don't but when comparing all properties there is no difference found.
  
  When it works I find this in the map file:
  
                  0x0000000000001270       0x52 C:/Program Files/Rowley Associates Limited/CrossWorks for ARM 4.10/lib/libc_v7em_t_le_eabi.a(libc2_asm.o)
                  0x0000000000001270                __aeabi_memcpy
                  0x0000000000001270                memcpy
                  0x000000000000127c                __aeabi_memcpy8
                  0x000000000000127c                __aeabi_memcpy4
  
  showing that it has taken memcpy() from this library, which is at the location defined by the library standard libraries directory property.
  
  Project which fail have identical settings but don't look to include the library and so can't link.
  
  Regards

  Hello,

  we are also using Kinetis Controller with Crossworks and haven’t faced any problems up to now.

  I think the problem is not reproducible in a small demo project?

  @Mark When you compared the settings of two projects, did you do this in the GUI or did you compare the project file?

  Hi
  
  I compared the GUI settings.
  
  In the meantime I have heard that the reference project works with CW4.3 but now with CW4.8 so something happens when there is a version change, although the exact version it fails is not known.

  Regards

  Mark

  Hi Mark,

  Sorry I missed this - can you attach the project file. I'll see if I can see something.

  Regards

  Hello Michael
  
  I have copied the project file(s) of one project that fails to link with newer CW versions. Maybe you spot the cause (the project is for a Kinetis part).

  Hi Mark,

  Looks like "Include Standard Libraries" is set to "No" in the "THUMB Release" configuration.

  Regards

  Michael

  Hi Michael
  
  Many thanks - when I did a check of these I either didn't notice the difference or the properties were being checked from a different target setting.
  It it still strange that older CW versions built with this same project but maybe a different target was selected?
  
  In any case the adjustment allowed all of the projects to link again so that is very positive - thanks again!
  
  Regards
  
  Mark

  Thanks all - that solved my problem, too.  The difference between "Solution properties" and "Project properties" is subtle and the CrossWorks IDE does not make this distinction especially clear!

  There's a drop down in the project explorer that you can use to show the properties that are set. I use this to figure out what is set.
