cyglto_plugin.dll not found

[lbertolotti]

I keep getting this error when using Cygwin GCC:
Build messages:

Code

||=== Build: Debug in cygwin_ex (compiler: Cygwin GCC) ===|
||error: -fuse-linker-plugin, but cyglto_plugin.dll not found|
||=== Build failed: 1 error(s), 0 warning(s) (0 minute(s), 1 second(s)) ===|

Has anyone managed to solve this?

Post the build log instead of the build messages and someone might spot the error.

I did not see any clear cause in Build log; Installing 64 bit Cygwin GCC to see if it works for me or it errors out.

I would try removing "-I../../../../cygwin64/lib/gcc/x86_64-pc-cygwin/6.4.0/include" and see if the error goes away.

Doing that generates:

Ok, that means it was corrupt/wrong files:

Do you know how cb_console_runner uses cygwin1.dll?

That question makes no sense.
