Issue

________________________________________________________________________

When working with Momentics IDE or command line tools, I am seeing:

+++

How do I resolve these kinds of errors?

Solution

________________________________________________________________________

Try using rebase.exe (available at https://cygwin.com/install.html) with msys-1.0.dll (i.e. C:\QNX650\host\win32\x86\usr\bin\msys-1.0.dll).
The utility changes the base of a non-pic DLL like msys
You can try base addresses 0x50000000 and 0x30000000

Example:
rebase.exe -b 0x50000000 msys-1.0.dll
rebase.exe -b 0x30000000 C:\QNX650\host\win32\x86\usr\bin\msys-1.0.dll

If, when running this tool, you get this error:
msys-1.0.dll: skipped because wrong machine type.

To fix "wrong machine type":

The error appears when using the 64-bit version of rebase.exe

Use the 32-bit version of rebase.exe
