Revert "build: replace which with Bash command built-in"

2021-03-03T22:02:30Z

This reverts commit c7aec47e5e3a3ff7b5fdaa11cd1e62cae6746acb. The original commit replaces 'which' with 'command'. Sadly most of them are not equivalent and for 'which -a', there is no easy replacements that would not reimplement PATH parsing logic. Hence revert. Keeping a dependency on which is absolutely fine.

build: replace which with Bash command built-in

2021-01-04T18:32:25Z

`which` utility is not shipped by default for example on recent Arch Linux and then any steps relying on its presence fails, like for example following Python3 prereq build check: $ python3 --version Python 3.9.1 $ make /bin/sh: line 1: which: command not found /bin/sh: line 1: which: command not found /bin/sh: line 1: which: command not found ... Checking 'python3'... failed. ... Fix this by switching to Bash builtin `command` which should provide same functionality. Fixes: FS#3525 Signed-off-by: Petr Štetiar

Fix the bug in ccache support due to this change. https://github.com/openwrt/openwrt/commit/bfc433efd4a0c6875a92981d1bd2a5e3e60c61c6 The new cmake uses this for the wrapper. https://cmake.org/cmake/help/v3.19/prop_tgt/LANG_COMPILER_LAUNCHER.html Signed-off-by: Hirokazu MORIKAWA

cmake.mk,rules.mk: fix host builds using CMake and ccache

2020-11-28T15:17:58Z

Commit f98878e4c17d ("cmake.mk: set C/CXX compiler for host builds as well") has introduced regression as it didn't taken usage of ccache into the account so fix it by handling ccache use cases as well. In order to get this working we need to export HOSTCXX_NOCACHE in rules.mk as well.

cmake.mk: set C/CXX compiler for host builds as well

2020-11-27T13:46:13Z

Without this, cmake will use whatever CC/CXX is set to, which could be clang. In that case, at least libjson-c/host will fail to compile. Signed-off-by: Rosen Penev

cmake: Disable use of package registries

2020-08-24T16:53:59Z

CMake provides a user package registry (stored in ~/.cmake/packages) and a system package registry (not available on non-Windows platforms). The "export(PACKAGE)" command may store information in the user package registry, and the "find_package()" command may search both user and system package registries for information. This sets various variables to disable the use of these package registries (both saving and retrieval of package information). This also sets deprecated variables that perform similar functions, in case external toolchains include older versions of CMake. Signed-off-by: Jeffery To

cmake: Install host packages to lib instead of lib64

2019-12-22T23:22:07Z

Several CMake packages such as log4cplus and protobuf(-c) install to lib64 instead of lib on some hosts. This completely breaks rpath linking. Override it globally to avoid fixing each package individually. Signed-off-by: Rosen Penev Tested-by: Sebastian Kemper

build: use CMAKE_SOURCE_SUBDIR variable to cmake.mk

2018-09-29T15:23:11Z

Sometimes, the CMakeLists.txt file is not in the root directory of a repo. In those cases, the CMAKE_SOURCE_SUBDIR variable can be specified to use CMakeLists.txt from a subdirectory instead. Signed-off-by: Amol Bhave

cmake: skip build system check on compile

2017-02-21T12:03:20Z

cmake checks the build system and its variables on its own to detect if the makefiles need to be regenerated. Unfortunately this can invalidate overrides passed in the Build/Configure step. On non-Linux systems this breaks the build when switching between targets of the same package architecture. Fix this by forcibly disabling the build system check and relying on the LEDE build system to take care of these things Signed-off-by: Felix Fietkau
