tclibc-baremetal: Supply missing /bin/sh target in the baremetal sdk

2022-01-11T15:48:11+00:00

SDK recipes now require a provider for /bin/sh, this should come from nativesdk-sdk-provides-dummy which is added by default to Linux SDKs, however tclibc-baremetal requires us to explicitly add its new dependency to TOOLCHAIN_HOST_TASK, otherwise we get a packaging error while generating an SDK. e.g. package packagegroup-cross-canadian-qemuriscv32-1.0-r0.x86_64_nativesdk requires gdb-cross-canadian-riscv32, but none of the providers can be installed - conflicting requests - nothing provides /bin/sh needed by gdb-cross-canadian-riscv32-11.1-r0.x86_64_nativesdk (From OE-Core rev: 8acb88cfe56735530280bab53a871c236f2fd54f) Signed-off-by: Alejandro Enedino Hernandez Samaniego Signed-off-by: Richard Purdie

Convert to new override syntax

2021-08-02T14:44:10+00:00

This is the result of automated script conversion: scripts/contrib/convert-overrides.py converting the metadata to use ":" as the override character instead of "_". (From OE-Core rev: 42344347be29f0997cc2f7636d9603b1fe1875ae) Signed-off-by: Richard Purdie

tclibc-baremetal: Include qemu on the SDK

2020-02-15T22:42:14+00:00

Since we now have an example recipe on meta-skeleton to build baremetal applications using OpenEmbedded, a user produced SDK should be able to run such application. Include nativesdk-qemu on TOOLCHAIN_HOST_TASK so its built inside the baremetal based SDK.

tclibc-baremetal.inc: Remove BASEDEPENDS on compilerlibs

2018-09-11T08:05:35+00:00

Without a libc the gcc-runtime provider of compilerlibs does not compile. As such avoid the default dependence on the virtual/${TARGET_PREFIX}compilerlibs provider.

tclibc: For newlib and baremetal disable some security features

2018-09-11T08:05:35+00:00

With GCCPIE being enabled by default with security_flags.inc the compiler will by default attempt to compile and link programs as PIE. The targets that use newlib and baremetal in general do not support PIE or are otherwise unable to use it due to how embedded targets are compiled and executed. As such it makes sense to disable PIE by default for these libc's in order to prevent build failures. For baremetal tclibc there are no libc features or implementation as such there is no implementation for the strong stack protector by default.

bitbake.conf: make libc over-ride lower priority than _forcevariable

Fix long standing quirk, _forcevariable is documented as being the highest priority over-ride. (From OE-Core rev: b3598b8f1ed1cdc7849e1e4f30d618e87e1bf582) Signed-off-by: Andre McCurdy Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

tclibc-baremetal: Adds virtual/crypt to ASSUME_PROVIDED

2018-05-08T15:14:14+00:00

When trying to build meta-toolchain using TCLIBC = "baremetal" bitbake throws an error due to a mising dependency: ERROR: Nothing PROVIDES 'virtual/crypt' glibc PROVIDES virtual/crypt but was skipped: PREFERRED_PROVIDER_virtual/libc set to musl, not glibc musl PROVIDES virtual/crypt but was skipped: PREFERRED_PROVIDER_virtual/i586-poky-elf-libc-for-gcc set to baremetal, not musl libxcrypt PROVIDES virtual/crypt but was skipped: Recipe only applies in nativesdk case for now This is caused by the changes on commit: 29f65bda6d2c9fea4adb125c4857ee64f9312b9f nativesdk-glibc: Split glibc and libcrypt to use libxcrypt instead This is where the concept of virtual/crypt was introduced. This patch adds virtual/crypt to ASSUME_PROVIDED on tclibc-baremetal, providing the missing wiring to build meta-toolchain on baremetal correctly.
