Hi All, Just been trying to compile rtl-sdr on my Windows7x64; so I have cloned the trunk repository, download mingw64, download cmake, get libusb-1.0 for windows and get pthreads-win32. After all I have configured cMake with the parameter show below: CMAKE_RC_FLAGS:STRING= CMAKE_VERBOSE_MAKEFILE:BOOL=0 CMAKE_RC_COMPILER:FILEPATH=C:/Program Files/mingw-builds/x64-4.8.1-posix-seh-rev5/mingw64/bin/windres.exe CMAKE_AR:FILEPATH=C:/Program Files/mingw-builds/x64-4.8.1-posix-seh-rev5/mingw64/bin/ar.exe CMAKE_C_FLAGS:STRING= CMAKE_C_FLAGS_DEBUG:STRING= CMAKE_EXE_LINKER_FLAGS_DEBUG:STRING= CMAKE_USE_RELATIVE_PATHS:BOOL=1 CMAKE_C_STANDARD_LIBRARIES:STRING=-lkernel32 -luser32 -lgdi32 -lwinspool -lshell32 -lole32 -loleaut32 -luuid -lcomdlg32 -ladvapi32 -lstdc++ CMAKE_C_COMPILER:FILEPATH=C:/Program Files/mingw-builds/x64-4.8.1-posix-seh-rev5/mingw64/bin/x86_64-w64-mingw32-gcc.exe CMAKE_CODEBLOCKS_EXECUTABLE:FILEPATH=C:/Program Files/mingw-builds/x64-4.8.1-posix-seh-rev5/mingw64/bin/mingw32-make.exe LIBUSB_INCLUDE_DIR:PATH=E:/Staniscia/PRIVATO/RTL_SDR/libusbx/include/libusbx-1.0 LIBUSB_LIBRARIES:FILEPATH=E:/Staniscia/PRIVATO/RTL_SDR/libusbx/MinGW64/static/libusb-1.0.a THREADS_PTHREADS_INCLUDE_DIR:PATH=E:/Staniscia/PRIVATO/RTL_SDR/pthreads-win32/Pre-built.2/include THREADS_PTHREADS_WIN32_LIBRARY:FILEPATH=E:/Staniscia/PRIVATO/RTL_SDR/pthreads-win32/Pre-built.2/lib/x64/libpthreadGC2.a and I don't have any warning from cMake but when I make the project I have this: ---------------------- E:\Staniscia\PRIVATO\RTL_SDR\repo\rtl-sdr\build>mingw32-make.exe clean E:\Staniscia\PRIVATO\RTL_SDR\repo\rtl-sdr\build>mingw32-make.exe [ 5%] Building C object src/CMakeFiles/libgetopt_static.dir/getopt/getopt.c.obj Linking C static library liblibgetopt_static.a [ 5%] Built target libgetopt_static [ 10%] Building C object src/CMakeFiles/rtlsdr_shared.dir/librtlsdr.c.obj [ 15%] Building C object src/CMakeFiles/rtlsdr_shared.dir/tuner_e4k.c.obj [ 21%] Building C object src/CMakeFiles/rtlsdr_shared.dir/tuner_fc0012.c.obj [ 26%] Building C object src/CMakeFiles/rtlsdr_shared.dir/tuner_fc0013.c.obj [ 31%] Building C object src/CMakeFiles/rtlsdr_shared.dir/tuner_fc2580.c.obj [ 36%] Building C object src/CMakeFiles/rtlsdr_shared.dir/tuner_r820t.c.obj Linking C shared library librtlsdr.dll [ 36%] Built target rtlsdr_shared [ 42%] Building C object src/CMakeFiles/rtl_adsb.dir/rtl_adsb.c.obj Linking C executable rtl_adsb.exe [ 42%] Built target rtl_adsb [ 47%] Building C object src/CMakeFiles/rtl_eeprom.dir/rtl_eeprom.c.obj Linking C executable rtl_eeprom.exe [ 47%] Built target rtl_eeprom [ 52%] Building C object src/CMakeFiles/rtl_fm.dir/rtl_fm.c.obj Linking C executable rtl_fm.exe [ 52%] Built target rtl_fm [ 57%] Building C object src/CMakeFiles/rtl_sdr.dir/rtl_sdr.c.obj Linking C executable rtl_sdr.exe [ 57%] Built target rtl_sdr [ 63%] Building C object src/CMakeFiles/rtl_tcp.dir/rtl_tcp.c.obj ..\..\src\rtl_tcp.c: In function 'gettimeofday': ..\..\src\rtl_tcp.c:112:10: error: invalid suffix "Ui64" on integer constant tmp -= 11644473600000000Ui64; ^ src\CMakeFiles\rtl_tcp.dir\build.make:57: recipe for target 'src/CMakeFiles/rtl_tcp.dir/rtl_tcp.c.obj' failed mingw32-make.exe[2]: *** [src/CMakeFiles/rtl_tcp.dir/rtl_tcp.c.obj] Error 1 CMakeFiles\Makefile2:319: recipe for target 'src/CMakeFiles/rtl_tcp.dir/all' failed mingw32-make.exe[1]: *** [src/CMakeFiles/rtl_tcp.dir/all] Error 2 Makefile:115: recipe for target 'all' failed mingw32-make.exe: *** [all] Error 2 ---------------------- Someone can help me?
