make stopped with error "Recursive variable 'PROTOC' references itself"

[Donggyu Lee]

I am building libVLC on Ubuntu for win32 (cross-compile).
I'm following this page (https://wiki.videolan.org/Win32Compile/)
some problems has been occured, but managed to solve them.
but this error, I can't deal with it.

"../../contrib/src/protobuf/rules.mak:19: *** Recursive variable 'PROTOC' references itself (eventually). Stop"

rules.mak: 19th line is like this
PROTOC = $(error $(PROTOC) version $(SYS_PROTOC) doesn't match the protobuf $(PROTOBUF_VERSION) we're building

PROTOC variable is using PROTOC variable itself !

what can I do to make successfully?

Straight cross-compilation is not alive method. I've tried. Maintainers recognize this problem and recommend workaround: docker method

Thank you, I'll try this one.

./extra/package/win32/build.sh is also working, but you have to setup your environment and apply some patches on mingw or maybe download the development version.

Nevertheless, if you just want to compile and not bother with the environment itself, use docker
