For Linux builds, if strlcpt and strlcat are already provided, cmake is
given an empty list of sources to build for the "misc" library. Newer
versions of cmake throw an error for this. In this case, we should just
avoid building the library.
Failure pattern:
CMake Error at external/misc/CMakeLists.txt:35 (add_library):
No SOURCES given to target: misc
CMake Generate step failed. Build files cannot be regenerated correctly.
Fixes#319
works with cygwin and x86_64-w64-mingw32-gcc/x86_64-w64-mingw32-g++
from the package installer of cygwin.
To use that add the following lines to .bash_profile
export CC=x86_64-w64-mingw32-gcc
export CXX=x86_64-w64-mingw32-g++
you also need cmake from cygwin
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
