Linux Makefile project is not building from MSBuild (builds fine from Visual Studio)

Issue Description

Linux Makefile project is not building from MSBuild (builds fine from Visual Studio)

Steps to Reproduce

In Visual Studio add a remote connection (Tools > Options > Cross Platform > Connection Manager > Add)
In Visual Studio create a new "Makefile project"
Rename it to "myprog"

Add file main.cpp like this

#include "stdio.h"
int main()
{
	printf("Hello");
	return 0;
}

Add file makefile (no extension) like this (note, it needs real tabs, not replaced by spaces, otherwise you'd get "*** missing separator")

src = $(wildcard *.cpp)
obj = $(src:.c=.o)
x64/Debug/myprog: $(obj)
	$(CC) -o $@ $^ $(LDFLAGS)
.PHONY: clean
clean:
	rm -f $(obj) x64/Debug

In Project Propertied > Remote Build specify:
Build Command Line: make
Outputs: $(Platform)/$(Configuration)/myprog

Make sure project builds from Visual Studio
Delete bin and obj files from the project folder
Open "Developer Command Prompt for VS 2019", change current folder to the project folder, run the following command :

msbuild /property:Configuration=Debug /property:Platform=x64 /verbosity:normal .\myprog.vcxproj

It fails. Note, if the folder obj\x64\Debug exists (even empty), it works.

Expected Behavior

Should build

Actual Behavior

You will get the following output:

>msbuild /property:Configuration=Debug /property:Platform=x64 /verbosity:normal .\myproj.vcxproj

Analysis

If I add the following workaround (modify project file), it starts to work:

  <Target Name="WorkaroundForMakefileIssue" BeforeTargets="_ConsolidateSourcesToCopy">
    <MakeDir Directories="obj\x64\$(Configuration)" />
  </Target>

@benvillalobos, do you have any update on this issue? ETA?

[xXTurnerLP]

This is a problem I had and still have, workaround is to kill MSBuild before each build (taskkill /f /im MSBuild.exe in cmd)

but i have a shit ton of other errors with nothing more than a stacktrace, msbuild is so fucking shit..

[benvillalobos]

The workaround here is the solution I'd expect. MSBuild doesn't control the Linux.Makefile.Targets file. I see it's installed under VS, is this on the cpp side of things? @yuehuang010

It looks like ConsolidateSourcesToCopy could do an existence check on the output directory if it doesn't exist.
