this step unify the builing system for all platforms (windows, linux,
osx and *BSD)
* Requirements:
- gcc/clang (C/C++ compiler) (in debian build-essential)
- cmake (in debian cmake)
- git if you build from source (in debian git)
- posix threads
** Requirements on *BSD/macOS:
- portaudio
** Optional Requirements:
- gpsd (in debian libgps-dev)
- libhamlib (in debian libhamlib-dev)
** Optional Requirements in Linux
- udev (in debian libudev-dev)
- alsa (in debian libasound2-dev)
* Main changes:
- version is now set only on CMakeLists.txt and automatically used
on the code
- cpu flags are auto-discovered in the default build and it works
on gcc/clang/msvc on x86/x86_64/arm; you can force cpu flags with
-DFORCE_SSE=1 for example (see CMakeLists.txt on root)
- use a more "complex" tag on generic.conf to facilitate parsing
by cmake (not more platform dependent). Now it is %C% or %R% for
example
- target `tocalls-symbols` is now called `data-update`
- created debian/ directory to contains files to use debuild
* Example to build:
mkdir build && cd build
cmake ..
make
make install
make install-conf
then you have the binary files on src/ and in the system directory
* CMake options (see the head of CMakeLists.txt)
- FORCE_SSE force sse instruction
- FORCE_SSSE3 force ssse3 instruction
- FORCE_SSE41 force ssse4.1 instruction
- OPTIONAL_TEST compile optional test (might be broken)
- BUILD_TESTING enable tests (ctest framework)
- CMAKE_INSTALL_PREFIX if you want to change your install path
prefix
for example:
cmake .. -DOPTIONAL_TEST=ON

*
|
|
* Module: strlcpy.c
|
|
*
|
|
* Purpose: Safe string functions to guard against buffer overflow.
|
|
*
|
|
* Description: The size of character strings, especially when coming from the
|
|
* outside, can sometimes exceed a fixed size storage area.
|
|
*
|
|
* There was one case where a MIC-E format packet had an enormous
|
|
* comment that exceeded an internal buffer of 256 characters,
|
|
* resulting in a crash.
|
|
*
|
|
* We are not always meticulous about checking sizes to avoid overflow.
|
|
* Use of these functions, instead of strcpy and strcat, should
|
|
* help avoid issues.
|
|
*
|
|
* Orgin: From OpenBSD as the copyright notice indicates.
|
|
* The GNU folks didn't think it was appropriate for inclusion
|
|
* in glibc. https://lwn.net/Articles/507319/
|
|
*
|
|
* Modifications: Added extra debug output when strings are truncated.
|
|
* Not sure if I will leave this in the release version
|
|
* or just let it happen silently.
|
|
