toolchain: sdk: ib: allow external toolchain override

2026-02-20T21:54:26Z

Allow building imagebuilder and/or sdk with dependency on the same external toolchain as used to build the imagebuilder or sdk (so that ib and sdk may be built using an external toolchain).

build: conditionally build llvm bpf toolchain by default

2025-02-07T10:16:08Z

Unless another toolchain is present (or selected), build the bpf toolchain whenever a package is selected that needs it. Signed-off-by: Felix Fietkau

loongarch64: new target

2024-05-04T06:14:16Z

Add target for Loongson LoongArch64-based boards. LoongArch is a new RISC ISA developed by Loongson. It's a bit like MIPS or RISC-V. LoongArch includes both 32-bit and 64-bit versions (LoongArch32/LoongArch64). Loongson 3A5000 and 3A6000 are the two existing CPUs of LoongArch64 and is used for PC products. It's BIOS supports ACPI and UEFI-only boot. These CPUs supports SMP and SMT. At present only LoongArch64 is supported by linux kernel. Toolchain requirement: binutils >= 2.40 gcc >= 13.1 For details, please check the following links: https://lwn.net/Articles/861951/ https://loongson.github.io/LoongArch-Documentation/README-EN.html Signed-off-by: Weijie Gao

scripts/ext-toolchain: implement external GCC version detection

2023-10-20T14:13:31Z

Some package may needs to enable compatibility option based on the GCC version. Currently the GCC version is set based on the default value and doesn't actually reflect the real value provided by the external toolchain if used. Fix this by correctly detecting the GCC version in the external toolchain and set the correct value in CONFIG_GCC_VERSION. A new option is added in menuconfig to manually set the GCC version if needed. Signed-off-by: Christian Marangi

treewide: strip useless `default n` Kconfig lines

2023-02-03T11:50:15Z

Kconfig docs say: > The default value deliberately defaults to 'n' in order to avoid > bloating the build. Apply this rule everywhere, to avoid more cloning of bad examples Signed-off-by: Tony Butler

toolchain: Include ./include/fortify for external musl toolchain

2022-09-12T21:34:10Z

When building with an external toolcahin with musl also include ./include/fortify by default. This is also done when we build with the internal toolchain using musl libc. Without this extra include the fortify source feature is not working when using an external musl toolchain. All binaries were compiled without fortify source when an external musl toolchain was used. All binaries release done by the OpenWrt project use the internal toolcahin where fortify source is working. Signed-off-by: Hauke Mehrtens

tools/dwarves: add host package

2022-05-18T10:32:06Z

dwarves is a set of tools that use the debugging information inserted in ELF binaries by compilers such as GCC. Utilities in the dwarves suite include pahole, which can be used to find alignment holes in structs and classes, and also extracts other information such as CPU cacheline alignment, helping pack those structures to achieve more cache hits. These tools are also used to encode and read the BTF type information format used with the bpf syscall, making this a Linux build dependency when using kernel BTF information. Signed-off-by: Tony Ambardar Signed-off-by: Felix Fietkau [bump to 1.23, add elfutils dep, drop host lib usage, drop cmake release target, use RM macro] Signed-off-by: Stijn Tintel

build: add support for using prebuilt LLVM toolchain

2021-11-04T19:06:14Z

When the prebuilt llvm toolchain is unpacked into the source dir, it is automatically picked up and used by the build system, and eBPF based packages can be selected Signed-off-by: Felix Fietkau

llvm-bpf: support creating a tarball in bin

2021-11-04T15:59:22Z

This can be used for adding the toolchain to an existing tree without having to build it from scratch. Enable building the toolchain + tarball by default on buildbot Signed-off-by: Felix Fietkau

build: fix bpf toolchain dependency for qosify

2021-11-01T17:41:20Z

Add hidden symbols to fix defaults with CONFIG_DEVEL unset Signed-off-by: Felix Fietkau
