problem with make in cross platform project Linux/Windows

[acapola]

My project is very simple: it consist in only one cpp file which needs one library (which I try to link statically, but end up with the dynamic one, but that's a separate matter)
I need to build it on windows and on linux, so I created one project configuration for each platform and edited the path to search libraries in each configuration.
I started with linux, got it to work and then moved to windows, editing the windows configuration, got it to work, job done
Well, now linux build is broken
Of course I switched back to the linux configuration, but somehow it seems that the windows configuration impact/confuse make on linux.
I get the following error message:

/bin/sh -c '/usr/bin/make -e -f Makefile'
make: Warning: File `Makefile' has modification time 0.025 s in the future
----------Building project:[ ktcl - Debug ]----------
make[1]: Entering directory `/media/sf_dev/tcl/ktcl'
Debug/main.cpp.o.d:1: *** multiple target patterns. Stop.
make[1]: Leaving directory `/media/sf_dev/tcl/ktcl'
make: *** [All] Error 2
1 errors, 0 warnings

What can I do to solve that ?
or, alternatively, is there any recommended way to do such cross platform project ?

set your system clocks with network time protofol & use some source control like git that'll stamp files you edit to the server time.

thanks for the advices, I've got rid of that time skew, but the main problem remains:

/bin/sh -c '/usr/bin/make -e -f Makefile'
----------Building project:[ ktcl - Debug ]----------
make[1]: Entering directory `/media/sf_dev/tcl/ktcl'
Debug/main.cpp.o.d:1: *** multiple target patterns. Stop.

do your intermediate folders overlap by any chance? it sortof looks like you're on a usb key (or not?). On Linux you'd mount flash or ssd drives with -relatime or -noatime; timestamps become even less reliable.

My build paths are declared as $(VCTEMP)/$(ProjectName)/$(ConfigurationName) to avoid toe-treading. I assume you already checked for hidden files.

indeed the intermediate directory was the same one: linux is in a vm running on windows. the code lite project is in a directory shared between the virtual machine and the host.
The problem is fixed now, by creating a new configuration for linux with a dedicated output directory.

Thanks for the hints
