How can know mgw version of my ubuntu

[linz]

I compile by make wallet qt file
get error as follow

/usr/bin/ld: cannot find -lboost_system-mgw49-mt-sd-1_55
/usr/bin/ld: cannot find -lboost_filesystem-mgw49-mt-sd-1_55
/usr/bin/ld: cannot find -lboost_program_options-mgw49-mt-sd-1_55
/usr/bin/ld: cannot find -lboost_thread-mgw49-mt-sd-1_55 collect2:
error: ld returned 1 exit status Makefile:532: recipe for target 'monix-qt' failed

I think it is problem with version of mgw49-mt-sd-1_55
here is qt file codes

Code:

# for boost 1.37, add -mt to the boost libraries
# use: qmake BOOST_LIB_SUFFIX=-mt
# for boost thread win32 with _win32 sufix
# use: BOOST_THREAD_LIB_SUFFIX=_win32-...
# or when linking against a specific BerkelyDB version: BDB_LIB_SUFFIX=-4.8

Code:

BOOST_LIB_SUFFIX=-mgw49-mt-sd-1_55
BOOST_INCLUDE_PATH=C:/deps/boost_1_55_0
BOOST_LIB_PATH=C:/deps/boost_1_55_0/stage/lib
BDB_INCLUDE_PATH=C:/deps/db-4.8.30.NC/build_unix
BDB_LIB_PATH=C:/deps/db-4.8.30.NC/build_unix
OPENSSL_INCLUDE_PATH=C:/deps/openssl-1.0.1j/include
OPENSSL_LIB_PATH=C:/deps/openssl-1.0.1j
MINIUPNPC_LIB_SUFFIX=-miniupnpc
MINIUPNPC_INCLUDE_PATH=C:/deps/miniupnpc
MINIUPNPC_LIB_PATH=C:/deps/miniupnpc
QRENCODE_INCLUDE_PATH=C:/deps/qrencode-3.4.4
QRENCODE_LIB_PATH=C:/deps/qrencode-3.4.4/.libs

You're trying to compile bitcoin core inside MinGW on Windows, instead of Ubuntu. Or are you running Ubuntu inside Windows Subsystem for Linux? 

Either way, you're missing the Boost libraries and that's why the compilation is failing. On Ubuntu you can install them with apt-get install libboost-system-dev libboost-filesystem-dev libboost-program-options-dev libboost-thread-dev.

But MinGW does not have apt, so are you sure you're not actually compiling Core from inside WSL Ubuntu?
