Hello, Matthias Klose, le dim. 23 nov. 2025 07:05:44 +0100, a ecrit: > there's a first build log on hurd-amd64,
There are earlier build logs on the -19 version: https://buildd.debian.org/status/fetch.php?pkg=llvm-toolchain-19&arch=hurd-amd64&ver=1%3A19.1.7-17&stamp=1763842985&raw=0 -- Compiler-RT supported architectures: x86_64 -- Failed to find compiler-rt builtins library for x86_64-unknown-hurd-gnu0.9 CMake Error at /build/reproducible-path/llvm-toolchain-19-19.1.7/compiler-rt/cmake/Modules/AddCompilerRT.cmake:276 (message): Cannot find builtins library for the target architecture Call Stack (most recent call first): /build/reproducible-path/llvm-toolchain-19-19.1.7/compiler-rt/lib/orc/CMakeLists.txt:135 (add_compiler_rt_runtime) I have not yet taken the time to investigate more closely why liborc fails to find compiler-rt. Possibly it's simply looking for asan runtime symbols or such, which are not ported to GNU/Hurd yet. What I have been doing in unreleased so far is to just disable liborc in a crude way: disable orc by hand for now until ORC_SUPPORTED_OS is fixed Index: llvm-toolchain-21-21.1.5/compiler-rt/cmake/Modules/AllSupportedArchDefs.cmake =================================================================== --- llvm-toolchain-21-21.1.5.orig/compiler-rt/cmake/Modules/AllSupportedArchDefs.cmake +++ llvm-toolchain-21-21.1.5/compiler-rt/cmake/Modules/AllSupportedArchDefs.cmake @@ -116,7 +116,7 @@ if (UNIX) if (OS_NAME MATCHES "Linux") set(ALL_ORC_SUPPORTED_ARCH ${X86_64} ${ARM64} ${ARM32} ${PPC64} ${LOONGARCH64}) else() - set(ALL_ORC_SUPPORTED_ARCH ${X86_64} ${ARM64} ${ARM32}) + set(ALL_ORC_SUPPORTED_ARCH ${ARM64} ${ARM32}) endif() endif() > dh_install --list-missing > dh_install: warning: Please use dh_missing --list-missing/--fail-missing > instead > dh_install: warning: This feature will be removed in compat 12. > dh_install: warning: Cannot find (any matches for) > "usr/lib/llvm-21/lib/clang/21*/lib/*/*clang_rt*" (tried in ., debian/tmp) > > dh_install: warning: libclang-rt-21-dev missing files: > usr/lib/llvm-21/lib/clang/21*/lib/*/*clang_rt* > dh_install: error: missing files, aborting > make[1]: *** [debian/rules:1906: override_dh_install] Error 255 > > please check, if the compiler-rt is usable on hurd-amd64, Yes, its testsuite passes fine: Total Discovered Tests: 311 Unsupported : 151 (48.55%) Passed : 159 (51.13%) Expectedly Failed: 1 (0.32%) > then we can re-enable it. Yes, please. Better rather disable just liborc: ifneq (,$(filter $(DEB_HOST_ARCH),hurd-amd64)) STAGE_ALL_CMAKE_EXTRA += -DCOMPILER_RT_BUILD_ORC=OFF endif I have submitted https://salsa.debian.org/pkg-llvm-team/llvm-toolchain/-/merge_requests/200 doing that in the 21 branch.
