Hello,

I'm working on a project with a recent version of the Marlin firmware (https://github.com/MarlinFirmware/Marlin/tree/261c6f4b96541435de786ddbafd491bc2a...) and it compiles fine in Arduino 1.8.7 (and 1.9.0 Beta Build 88) but I get errors with the Visual Micro plugin. I think the changed folder structure of the Marlin project screws up the compiling process.

With all default VM options I get:

error*: n.cpp: No such file or directory
warning*: -x c++ after last input file has no effect
fatal error*: no input files
   compilation terminated
 

And with 'Deep Search' for libraries disabled I get at one point:

error*: n.cpp: No such file or directory
fatal error*: no input files
   compilation terminated
 

I was using the current release of VM 1811.24.0 in Visual Studio 2017 Community 15.9.3.
See also attached logs of the compile process with and without deep search enabled.

Cheers Julian

OK with that trick the compiling step can advance but now I am getting an error at the linker (see file). The path is to long (German: Der Dateiname oder die Erweiterung ist zu lang).

I tried to find the same option as mentioned in the other post but I can not find it. Has the option maybe been renamed in the latest release of VM?

Cheers Julian

Thanks, but with both option set as suggested I get now a different error. Something like:

serial.cpp:23: In file included from

serial.h: 24:36: fatal error: ..\inc\MarlinConfigPre.h: No such file or directory
   compilation terminated 

and it continues... looks like we found a new edge case.

I tried now all four combinations. With Build in Project Intermediate disabled I get till to the linking step regardless which flag is set for Build uses configuration.

As soon I enable Build in Project Intermediate I get errors already at the compile step. Again regardless which flag is set for Build uses configuration.

I have got this setting $(Configuration)\ for Intermediate Directory. See also attached image.

There is no change without the \ and I get the same errors.

The first .h file where the compilation terminates is:

serial.cpp:23: In file included from

serial.h: 24:36: fatal error: ..\inc\MarlinConfigPre.h: No such file or directory
   compilation terminated 

and can be found in following locations:

1. C:\Files\Work\arduino\Marlin\Marlin\src\inc\MarlinConfigPre.h from the source code itself
2. C:\Files\Work\arduino\Marlin\Marlin\Release\src\inc\MarlinConfigPre.h from the intermediate build folder I suppose (actually from the first time when I try to build it)
3. C:\Files\Work\arduino\Marlin\Marlin\Release\Release\src\inc\MarlinConfigPre.h same as above but from the second attempt to build it
4. Pre.h third build ect. I do not think that should be like this ...

Basically every time I execute a build I get an extra Release folder.

I am sorry for the late reply. I had a busy week ... anyhow I tried now your suggestion.

In Tools > Options > Visual Micro I have now:
Build In Project Intermediate: False
Build Uses Configuration: True

In vMicro > Compiler
Deep Search for Libraries: Unselected
Verbose: Selected

I have noted that Excluding and Inlcuding folders takes quite some time and also produces high CPU load. After the exclude/inlcude cycle I checked if all the relevant files where without the red sign.
For safety measure I excluded the config folder containing example configuration files for each 3D printer vendor.

Never the less with this setup I get a path to long error at the linking step:

Linking it all together ...
# Coping cached core 26e3f2\core.a to a

"C:\Program Files (x86)\Arduino\hardware\tools\avr/bin/avr-gcc" -w -Os -g -flto -fuse-linker-plugin -Wl,--gc-sections,--relax -mmcu=atmega2560 -o in.ino.elf" in.cpp.o" core\serial.cpp.o"
... snip: bunch of *.cpp.o files see attached log ...
sd\usb_flashdrive\usb_host.cpp.o" .a" "-LC:\Users\Julian\AppData\Local\Temp\VMBuilds\Marlin\mega_atmega2560\Release" -lm
Der Dateiname oder die Erweiterung ist zu lang

Error linking for board Arduino/Genuino Mega w/ ATmega2560 (Mega 2560)
Build failed for project 'Marlin'
 

So I think there is no change so far. I got this result also before without including/ecluding folders.

Do you have any other suggestions?

Good idea, I will strip the build folder from the object paths during link.

ps: You can set your build folder to be a shorter path via "tools>options>visual micro>compiler>temp build folder"

OK thanks with that version it is now linking without problems:
