Breakpoint problem in IAR project

[spiras]

Hello, I used the wizart to import a IAR project in VS2017;
the project is setup to use IAR compiler;
the build succeeded and the target runs with JLink,
but breakpoints do not work.
There are some warnings I can’t figure how to fix:

• Not in executable format: File format not recognized.
• No executable has been specified and target does not support determining executable automatically
• No symbol table is loaded. Use the “file” command
• Warning: could not set a breakpoint on main. ‘Step into new instance’ will not work

Hi,

It looks like you are trying to debug a static library:

&"\"C:\\Users\\Public\\Projects\\ProvaErmesGDB\\VisualGDB\\Release\\ProvaErmesGDB.a\": not in executable format: File format not recognized\n"

Please note that static libraries cannot be programmed or debugged directly. Instead, they need to be linked into an executable project, that could be programmed and debugged as expected.

You can switch between building a static library and an executable via VS Project Properties -> Configuration -> General (see this page for a detailed description of MSBuild property types).

Thanks a lot!

don’t know why it ended up as a library

[support]

No problem. VisualGDB would create a library project when it detects that the original IAR project was a static library. The check is done using the “GOutputBinary” element in the IAR project file.

Most likely, your project was created using an older version of IAR and our importing plugin doesn’t handle it properly. If you could attach the .ewp file here (or send it via our support form), we will be happy to update our importer to handle it properly.  You don’t need to share any actual source code.

If you do not want to share the project file, you can also patch the IAR project importer on your side by cloning it from Github: https://github.com/sysprogs/BSPTools/tree/master/ProjectImporters/IARProjectImporter
