[PATCH] gr-osmosdr: fix build with boost > 1.73.0

by Gwenhael Goavec-Merou

boost/detail/endian.hpp has been marked as deprecated since boost 1.69.0. This file and boost/predef/detail/endian_compat.h are no more available. This patch suppress this header in some file, where not needed and move to correct header and new constants. It's retrocompatible for at least all boost release > 1.69.0 Signed-off-by: Gwenhael Goavec-Merou <gwenhael.goavec-merou(a)trabucayre.com> --- lib/airspy/airspy_source_c.cc | 1 - lib/airspyhf/airspyhf_source_c.cc | 1 - lib/hackrf/hackrf_source_c.cc | 6 +++--- lib/rtl/rtl_source_c.cc | 1 - 4 files changed, 3 insertions(+), 6 deletions(-) diff --git a/lib/airspy/airspy_source_c.cc b/lib/airspy/airspy_source_c.cc index 50150e5..f833588 100644 --- a/lib/airspy/airspy_source_c.cc +++ b/lib/airspy/airspy_source_c.cc @@ -33,7 +33,6 @@ #include <boost/assign.hpp> #include <boost/format.hpp> -#include <boost/detail/endian.hpp> #include <boost/algorithm/string.hpp> #include <boost/thread/thread.hpp> diff --git a/lib/airspyhf/airspyhf_source_c.cc b/lib/airspyhf/airspyhf_source_c.cc index 327fe19..b7494a8 100644 --- a/lib/airspyhf/airspyhf_source_c.cc +++ b/lib/airspyhf/airspyhf_source_c.cc @@ -33,7 +33,6 @@ #include <boost/assign.hpp> #include <boost/format.hpp> -#include <boost/detail/endian.hpp> #include <boost/algorithm/string.hpp> #include <boost/thread/thread.hpp> diff --git a/lib/hackrf/hackrf_source_c.cc b/lib/hackrf/hackrf_source_c.cc index eea5caa..fc48171 100644 --- a/lib/hackrf/hackrf_source_c.cc +++ b/lib/hackrf/hackrf_source_c.cc @@ -31,7 +31,7 @@ #include <stdexcept> #include <iostream> -#include <boost/detail/endian.hpp> +#include <boost/predef/other/endian.h> #include <gnuradio/io_signature.h> @@ -90,10 +90,10 @@ hackrf_source_c::hackrf_source_c (const std::string &args) // create a lookup table for gr_complex values for (unsigned int i = 0; i <= 0xffff; i++) { -#ifdef BOOST_LITTLE_ENDIAN +#ifdef BOOST_ENDIAN_LITTLE_BYTE _lut.push_back( gr_complex( (float(int8_t(i & 0xff))) * (1.0f/128.0f), (float(int8_t(i >> 8))) * (1.0f/128.0f) ) ); -#else // BOOST_BIG_ENDIAN +#else // BOOST_ENDIAN_BIG_BYTE _lut.push_back( gr_complex( (float(int8_t(i >> 8))) * (1.0f/128.0f), (float(int8_t(i & 0xff))) * (1.0f/128.0f) ) ); #endif diff --git a/lib/rtl/rtl_source_c.cc b/lib/rtl/rtl_source_c.cc index a371464..7f2e648 100644 --- a/lib/rtl/rtl_source_c.cc +++ b/lib/rtl/rtl_source_c.cc @@ -32,7 +32,6 @@ #include <boost/assign.hpp> #include <boost/format.hpp> -#include <boost/detail/endian.hpp> #include <boost/algorithm/string.hpp> #include <stdexcept> -- 2.27.0

[PATCH] librtlsdr: Allow device specification with an USB path

by Alexander Motzkau

I'm using a Raspberry with two similar devices but different antennas. Specifying the device via index didn't work, because the enumeration of devices changed from time to time. Therefore I implemented functions to give a USB path instead. This path looks the same as the Linux kernel uses (eg. "4-1.2") and contains the USB bus and port numbers. I'll hope you'll find my patch acceptable. Best Regards, Alex Add functions to query devices via path, and path from a device. The path is formatted similar to Linux USB device names (bus number, hyphen, ports separated by dots, eg. "4-1.2"). --- include/rtl-sdr.h | 25 +++++++ src/convenience/convenience.c | 10 +++ src/librtlsdr.c | 121 ++++++++++++++++++++++++++++++++++ 3 files changed, 156 insertions(+) diff --git a/include/rtl-sdr.h b/include/rtl-sdr.h index d64701e..e6ce33a 100644 --- a/include/rtl-sdr.h +++ b/include/rtl-sdr.h @@ -49,6 +49,31 @@ RTLSDR_API int rtlsdr_get_device_usb_strings(uint32_t index, char *product, char *serial); +/*! + * Get device index by USB path string. + * + * The path string has the format "bus-port.port..." + * (i.e. the bus number, followed by a hyphen, then + * followed by the port numbers separated by dots). + * + * \param path path string of the device + * \return device index of the device with the given path + * \return -1 if no matching device was found. + */ +RTLSDR_API int rtlsdr_get_index_by_path(const char *path); + +/*! + * Get the USB path. + * + * NOTE: The buffer should provide space for at least 32 bytes. + * + * \param index the device index + * \param buf buffer where the path will be written + * \param len size of the buffer + * \return 0 on success + */ +RTLSDR_API int rtlsdr_get_device_path(uint32_t index, char *buf, size_t len); + /*! * Get device index by USB serial string descriptor. * diff --git a/src/convenience/convenience.c b/src/convenience/convenience.c index 00cc2cc..55f82e2 100644 --- a/src/convenience/convenience.c +++ b/src/convenience/convenience.c @@ -268,6 +268,16 @@ int verbose_device_search(char *s) device, rtlsdr_get_device_name((uint32_t)device)); return device; } + /* does string match a path */ + if (s2[0] == '-') { + i = rtlsdr_get_index_by_path(s); + if (i >= 0) { + device = i; + fprintf(stderr, "Using device %d: %s\n", + device, rtlsdr_get_device_name((uint32_t)device)); + return device; + } + } /* does string exact match a serial */ for (i = 0; i < device_count; i++) { rtlsdr_get_device_usb_strings(i, vendor, product, serial); diff --git a/src/librtlsdr.c b/src/librtlsdr.c index 0146298..e3f03d7 100644 --- a/src/librtlsdr.c +++ b/src/librtlsdr.c @@ -1414,6 +1414,127 @@ int rtlsdr_get_device_usb_strings(uint32_t index, char *manufact, return r; } +static void get_device_path(libusb_device *dev, char *buf, size_t len) +{ + uint8_t port_numbers[16]; + int port_entries; + int i, count; + + count = snprintf(buf, len, "%d-", (int)libusb_get_bus_number(dev)); + if (count < 0) { + buf[0] = 0; + return; + } + else if ((size_t)count >= len) { + buf[len-1] = 0; + return; + } + + len -= count; + buf += count; + + port_entries = libusb_get_port_numbers(dev, port_numbers, sizeof(port_numbers)/sizeof(port_numbers[0])); + if (port_entries < 0) + return; + + for (i = 0; i < port_entries; i++) { + count = snprintf(buf, len, i ?
