Hi,

I was trying to build rtl-sdr on windows using mingw64 and stumbled upon the error described here [1]

[ 40%] Building C object src/CMakeFiles/rtl_adsb.dir/rtl_adsb.c.o Linking C executable rtl_adsb.exe libconvenience_static.a(convenience.c.o):convenience.c:(.text+0x1e5): undefined reference to `rtlsdr_set_tuner_gain_mode' libconvenience_static.a(convenience.c.o):convenience.c:(.text+0x1e5): relocation truncated to fit: R_X86_64_PC32 against undefined symbol `rtlsdr_set_tuner_gain_mode' libconvenience_static.a(convenience.c.o):convenience.c:(.text+0x1fb): undefined reference to `rtlsdr_get_tuner_gains' libconvenience_static.a(convenience.c.o):convenience.c:(.text+0x1fb): relocation truncated to fit: R_X86_64_PC32 against undefined symbol `rtlsdr_get_tuner_gains'

and so on....

I was able to build rtl-sdr using the attached patch. I exchange the order of linking libraries.
