build: prereq: tidy gcc version checks

2020-03-29T16:47:03Z

There is a restriction in the number of parameters(10) that may be passed to the SetupHostCommand macro so continually adding explicit gcc'n' version checks ends up breaking the compiler check for the later versions and oddballs like Darwin as was done in 835d1c68a0 which added gcc10. Drop all the explicitly specified gcc version checks. If a suitable gcc compiler is not found, it may be specified at the dependency checking stage after which that version will be symlinked into the build staging host directory. eg. 'CC=gccfoo CXX=g++foo make prereq' Signed-off-by: Kevin Darbyshire-Bryant Acked-by: Jo-Philipp Wich (cherry picked from commit 1fb3c003d68d3feaf797e8b64edccc9fa622d250)

build: add GCC 10 version detection

2020-03-29T16:46:57Z

Lets add GCC 10 detection to the build system as distributions like Fedora 32 have started shipping with it. Some tools like mtd-utils need work to compile under GCC10, but that will be next step. Signed-off-by: Robert Marko (cherry picked from commit 835d1c68a0f036c8b0d837a48b5a05fdfb2e8218)

build: cleanup possibly dangling Python 3 host symlink

2019-11-09T07:21:45Z

When switching from master branch to 19.07 or older, we need to ensure that Python symlink in staging bin directory points to Python 2. We can't rely completly just on SetupHostCommand as its executed only in cases when the $(STAGING_DIR_HOST)/bin/python doesn't already exist, so we need to remove it before running SetupHostCommand. This is a cherry-pick of 3b68fb57c938af3948ae4c2da61501183fbef649 with python3 instead of python2 Signed-off-by: Petr Štetiar Signed-off-by: Etienne Champetier

build: fixup python SetupHostCommand to use python2

2019-11-09T07:21:45Z

Here is a way to break your build env without this patch: 1) have python point to python3, and no python2 2) start the build, SetupHostCommand will create a symlink ./staging_dir/host/bin/python -> /usr/bin/python 3) build fails on scons because it can't find any python2 4) install python2 and restart the build 5) the build fails on wireless-regdb compile because python is python3 instead of python Signed-off-by: Etienne Champetier

build: remove GNU time dependency

2018-08-04T22:06:27Z

Replace the GNU time program invocation with a simple Perl script reporting the timing values. Since we require Perl anyway for the build system, we can as well use that instead of requiring a random GNU utility rarely installed by default.

build: prereq-build.mk: fix gcc/g++ SetupHostCommand invocation

2018-07-24T11:37:24Z

A missing comma caused the first command option to be considered part of the error message. Signed-off-by: Jo-Philipp Wich

include/prereq-build.mk: explicitly check for -f flag when using busybox time

2018-07-14T13:46:35Z

On Debian, busybox does have a time applet, but it does not support the -f flag. Catch this in prereq check to give users to proper error message. Signed-off-by: Matthias Schiffer

build: add busybox support to `time` prereq-check

2018-06-18T19:27:01Z

Busybox time supports the GNU time '-f' syntax used by the build time logging implemented in ff6e62b288c, however the prerequisite check added only works with GNU time installed as `time` or `gtime`. As busybox is a multicall binary, the name of the symlink setup by SetupHostCommand also must be changed from `gtime` to `time` to fix the value of argv[0]. This causes a number of shells (including bash) to use their builtin impelementation of time, so the sole invocation has been changed to use `env time` to use the value found on the $PATH.
