What is the meaning of this mmessage in IDA:

The decompiler assumes that the segment '.text' is read-only because of its NAME. All data references to the segment will be replaced by constant values. This may lead to drastic changes in the decompiler output. If the segment is not read-only, please change the segment NAME.

  • It's not an issue and it does not need to be fixed. Only if you are experiencing issues with the decompilation should you take the advice given in the message (or the reply below). May 10 at 16:51

What is the meaning of this message in IDA?

When you load a file into Ida (.exe, ⁣.dll, ⁣.bin,,.hex, etc.), it creates at least one segment for the memory address (you can add or remove segments on your own). Every segment has a unique name that you can change. A segment with the name .text means that the content of this segment is read-only and not writable. So if a piece of code is accessing this segment and changing a variable value in it, the message in your question will appear and say that the target segment is considered read-only, which results in wrong decompiled code.

How can we fix this issue in IDA Pro?

Two workarounds:

  1. Change the segment name to something else: View->Open subviews->Segments (Shift+F7), right click on the segment-->Edit, Change the name.
  2. Change the segment permission to read and write: Follow the above path and check the write and read check boxes.
