Describe the bug
elf linker complains that a file is not there while the file is clearly exsits in the correct location

To Reproduce
Steps to reproduce the behavior:

1. Use ESP8266Audio and ESP8266SAM library

Wierd
This instantly reminded me #1318
Checking it looks like the same/similar issue but I don't think it is. I currently think this is issue #1210

the command contains
.\libraries\ESP8266Audio\src*libopus*\silk\resampler_private_IIR_FIR.c.o
while the error states
.\libraries\ESP8266Audio\src*libous*\silk\resampler_private_IIR_FIR.c.o
Note the missing p in the error output

Given your description I would assume that in this case libopus is the right name and as such Sloeber generated the correct command
Which makes this different from #1318

[tyllurius]

That's exactly the error I have on my Win7 64bit pro PC; I referred it to #1318. Still I don't understand what is the difference to #1210?

[jantje]

#1318 sloeber makes a wrong command
#1210 windows does something with a to long command

Your command is way to long for windows so you need the workaround of #1210

[Kashouryo]

Big success! I replaced make with a newer version. Thank you guys!

Big sucess here, too! It also was issue #1210 in my case.
