Request for Comment: Creating a binary format output for rtl_power

by Bill Gaylord

Hello, I am working on making a binary format for rtl_power to save space on my server for observing the spectrum. I am wondering if anyone else would be interested in this idea. I am hoping keep the same format in terms of how the data is organized in the file but instead of using text use some form of binary format. For example for the date and time I think using a unix epoch timestamp would work. I am hoping to receive any comments or criticism. Thanks, KD9KCK

[PATCH] cmake: Go back CMake min ver. 3.8 by removing need for CMP0079

by Piotr Krysik

CMake 3.13 is not present in older (~2 years old) Linux distributions and GNU Radio requires min CMake version 3.8. All that is needed in order to avoid bumping CMake version is to not use 'target_link_libraries' in subdirectories. Here this is done by creating a list of needed libraries and adding them for linking at the end (like it was done in gr-osmosdr before porting to GNU Radio 3.8). One thing that is lost here is 'PRIVATE' statement in case of FCD libraries linking. --- CMakeLists.txt | 3 +-- lib/CMakeLists.txt | 7 ++++--- lib/airspy/CMakeLists.txt | 2 +- lib/airspyhf/CMakeLists.txt | 2 +- lib/bladerf/CMakeLists.txt | 2 +- lib/fcd/CMakeLists.txt | 5 +++-- lib/file/CMakeLists.txt | 2 +- lib/freesrp/CMakeLists.txt | 2 +- lib/hackrf/CMakeLists.txt | 2 +- lib/miri/CMakeLists.txt | 2 +- lib/osmosdr/CMakeLists.txt | 2 +- lib/redpitaya/CMakeLists.txt | 2 +- lib/rtl/CMakeLists.txt | 2 +- lib/rtl_tcp/CMakeLists.txt | 2 +- lib/sdrplay/CMakeLists.txt | 2 +- lib/soapy/CMakeLists.txt | 2 +- lib/uhd/CMakeLists.txt | 2 +- 17 files changed, 22 insertions(+), 21 deletions(-) diff --git a/CMakeLists.txt b/CMakeLists.txt index 7a2cf9d..cf24991 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -20,14 +20,13 @@ ######################################################################## # Project setup ######################################################################## -cmake_minimum_required(VERSION 3.13) +cmake_minimum_required(VERSION 3.8) include(GNUInstallDirs) project(gr-osmosdr CXX C) enable_testing() #policy setup cmake_policy(SET CMP0011 NEW) -cmake_policy(SET CMP0079 NEW) #select the release build type by default to get optimization flags if(NOT CMAKE_BUILD_TYPE) diff --git a/lib/CMakeLists.txt b/lib/CMakeLists.txt index d04cb1d..f8c9db7 100644 --- a/lib/CMakeLists.txt +++ b/lib/CMakeLists.txt @@ -41,7 +41,7 @@ if(CMAKE_COMPILER_IS_GNUCXX) endif() add_library(gnuradio-osmosdr SHARED) -target_link_libraries(gnuradio-osmosdr ${Boost_LIBRARIES} gnuradio::gnuradio-runtime) +list(APPEND gr_osmosdr_libs ${Boost_LIBRARIES} gnuradio::gnuradio-runtime) target_include_directories(gnuradio-osmosdr PRIVATE ${CMAKE_CURRENT_SOURCE_DIR} PUBLIC ${Boost_INCLUDE_DIRS} @@ -100,7 +100,7 @@ CHECK_CXX_SOURCE_COMPILES(" if(HAVE_CLOCK_GETTIME) message(STATUS " High resolution timing supported through clock_gettime.") set(TIME_SPEC_DEFS HAVE_CLOCK_GETTIME) -

[PATCH] rtl_tcp: Throw an exception if TCP connection fails

by argilo＠gmail.com

From: Clayton Smith <argilo(a)gmail.com> Currently, rtl_tcp_source_c repeatedly calls ::connect until it succeeds. This can result in 100% CPU utilization and/or a lot of network traffic. In addition, GUI applications like Gqrx freeze up. To solve these problems, I've changed the code to report an error if ::connect fails. Also, I removed rtl_tcp_source_f since it is no longer used, and corrected a few error messages in rtl_tcp_source_c so they print the correct class name. --- lib/rtl_tcp/rtl_tcp_source_c.cc | 10 +- lib/rtl_tcp/rtl_tcp_source_f.cc | 327 -------------------------------- lib/rtl_tcp/rtl_tcp_source_f.h | 125 ------------ 3 files changed, 5 insertions(+), 457 deletions(-) delete mode 100644 lib/rtl_tcp/rtl_tcp_source_f.cc delete mode 100644 lib/rtl_tcp/rtl_tcp_source_f.h diff --git a/lib/rtl_tcp/rtl_tcp_source_c.cc b/lib/rtl_tcp/rtl_tcp_source_c.cc index ecdeee0216..af8e30006b 100644 --- a/lib/rtl_tcp/rtl_tcp_source_c.cc +++ b/lib/rtl_tcp/rtl_tcp_source_c.cc @@ -98,7 +98,7 @@ static int is_error( int perr ) case WSAENOPROTOOPT: return( perr == ENOPROTOOPT ); default: - fprintf(stderr,"rtl_tcp_source_f: unknown error %d WS err %d \n", perr, werr ); + fprintf(stderr,"rtl_tcp_source_c: unknown error %d WS err %d \n", perr, werr ); throw std::runtime_error("internal error"); } return 0; @@ -200,7 +200,7 @@ rtl_tcp_source_c::rtl_tcp_source_c(const std::string &args) : WSADATA wsaData; int iResult = WSAStartup( MAKEWORD(2,2), &wsaData ); if( iResult != NO_ERROR ) { - report_error( "rtl_tcp_source_f WSAStartup", "can't open socket" ); + report_error( "rtl_tcp_source_c WSAStartup", "can't open socket" ); } #endif @@ -219,7 +219,7 @@ rtl_tcp_source_c::rtl_tcp_source_c(const std::string &args) : // FIXME leaks if report_error throws below int ret = getaddrinfo(host.c_str(), port_str, &hints, &ip_src); if (ret != 0) - report_error("rtl_tcp_source_f/getaddrinfo", + report_error("rtl_tcp_source_c/getaddrinfo", "can't initialize source socket" ); d_temp_buff = new unsigned char[payload_size]; // allow it to hold up to payload_size bytes @@ -261,8 +261,8 @@ rtl_tcp_source_c::rtl_tcp_source_c(const std::string &args) : report_error("SO_RCVTIMEO","can't set socket option SO_RCVTIMEO"); #endif // USE_RCV_TIMEO - while (::connect(d_socket, ip_src->ai_addr, ip_src->ai_addrlen) != 0) - ; // FIXME handle errors? + if (::connect(d_socket, ip_src->ai_addr, ip_src->ai_addrlen) != 0) + report_error("rtl_tcp_source_c/connect","can't open TCP connection"); freeaddrinfo(ip_src); int flag = 1; diff --git a/lib/rtl_tcp/rtl_tcp_source_f.cc b/lib/rtl_tcp/rtl_tcp_source_f.cc deleted file mode 100644 index a17594c916..0000000000 --- a/lib/rtl_tcp/rtl_tcp_source_f.cc +++ /dev/null @@ -1,327 +0,0 @@ -/* -*- c++ -*- */ -/* - * Copyright 2012 Hoernchen <la(a)tfc-server.de> - * Copyright 2012 Dimitri Stolnikov <horiz0n(a)gmx.net> - * - * GNU Radio is free software; you can redistribute it and/or modify - * it under the terms of the GNU General Public License as published by - * the Free Software Foundation; either version 3, or (at your option) - * any later version. - * - * GNU Radio is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

[PATCH] build: Allow building with GNU Radio master

by argilo＠gmail.com

From: Clayton Smith <argilo(a)gmail.com> Currently gr-iqbal does not build with GNU Radio's master branch, which declares itself to be version 3.9. This change allows both 3.8 and 3.9. --- CMakeLists.txt | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/CMakeLists.txt b/CMakeLists.txt index 1e8c0a5754..bc8a1aef0a 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -42,7 +42,13 @@ set(CMAKE_BUILD_TYPE ${CMAKE_BUILD_TYPE} CACHE STRING "") list(INSERT CMAKE_MODULE_PATH 0 ${CMAKE_SOURCE_DIR}/cmake/Modules) # Find GNURadio -find_package(Gnuradio "3.8" REQUIRED) +find_package(Gnuradio "3.8") +if(NOT Gnuradio_FOUND) + find_package(Gnuradio "3.9") + if(NOT Gnuradio_FOUND) + message(FATAL_ERROR "Unable to find GNURadio") + ENDIF(NOT Gnuradio_FOUND) +ENDIF(NOT Gnuradio_FOUND) # Set the version information here set(VERSION_MAJOR 3) -- 2.17.1
