From 37d5cd10f72d0342405940a605a907246ffb1fce Mon Sep 17 00:00:00 2001 From: widelec-BB Date: Tue, 22 Sep 2026 16:27:51 +0200 Subject: [PATCH] build: Allow to build on machines with CPU other than x86 and ARM Don't hard-fail on unknown processors; build interpreter-only x86 and arm64 remain the only optimized targets, but ppc64, riscv64 and others can now build and run with the generic core instead of dying at configure time. --- CMakeLists.txt | 12 ++++++++++-- 1 file changed, 10 insertions(+), 2 deletions(-) diff --git a/CMakeLists.txt b/CMakeLists.txt index 679470e64..d57445810 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -277,6 +277,7 @@ check_cxx_source_compiles("${TEST_CODE_BUILTIN_CLEAR_CACHE}" set(C_TARGET_CPU_ARM OFF) set(C_TARGET_CPU_X86 OFF) +set(C_TARGET_CPU_UNK OFF) option(OPT_FORCE_DYNREC "Force DYNREC dynamic recompiler (not x86-64 optimized)" OFF) @@ -307,9 +308,16 @@ elseif (CMAKE_SYSTEM_PROCESSOR STREQUAL "arm64" OR set(C_DYNREC ON) set(C_FPU_X86 OFF) set(C_UNALIGNED_MEMORY OFF) - else() - message(FATAL_ERROR "Unknown processor ${CMAKE_SYSTEM_PROCESSOR}") + message(WARNING "Unsupported processor ${CMAKE_SYSTEM_PROCESSOR}: " + "building interpreter-only, untested configuration") + + set(C_TARGET_CPU_UNK ON) + + set(C_DYNAMIC_X86 OFF) + set(C_DYNREC OFF) + set(C_FPU_X86 OFF) + set(C_UNALIGNED_MEMORY OFF) endif() check_include_file("libgen.h" HAVE_LIBGEN_H) -- 2.55.0
