But native out of tree builds are supported in autotools as well, why do you mention that, it\u0027s not a new feature?\n\nOh, you\u0027re right. Meson enforces out-of-tree builds, it\u0027s not a feature in that sense.\n\n\u003e Wonder how widely it is available on older GNU/Linux distros and less popular Unicies such as OpenBSD.\n\nFrom my point of view, it\u0027s availability should not be a problem. Especially since we require a quite old Meson version (0.59). It\u0027s also available on OpenBSD [1].\n\n\u003e Also to be tested is cross-building.\n\nGood point, will do this soon(ish).\n\n\u003e As I understand it the plan is to drop autoconf altogether because maintaining two build approaches in parallel would be a waste, right?\n\nIt does not make sense to maintain multiple build systems in my opinion. The idea is to drop Autotools, if we agree on Meson,  Let\u0027s see what kind of feedback we get.\n\n[1] https://openports.pl/path/devel/meson","commit_id":"29cd936ba0c332e7498360406d4ac9e4ba30789f"},{"author":{"_account_id":1000019,"name":"Xiaofan Chen","email":"xiaofanc@gmail.com","username":"xiaofan"},"change_message_id":"51fb02c3e0b42fc91dacdb246fbfa268ecbaf844","unresolved":true,"context_lines":[],"source_content_type":"","patch_set":4,"id":"7a4b0315_896cd9f8","updated":"2026-03-25 12:58:11.000000000","message":"Build under macOS seems to fail.\n\nmcuee@mcuees-MacBook openocd % meson setup build   \nThe Meson build system\nVersion: 1.10.2\nSource dir: /Users/mcuee/build/libusb/openocd\nBuild dir: /Users/mcuee/build/libusb/openocd/build\nBuild type: native build\nProject name: openocd\nProject version: 0.12.0\nC compiler for the host machine: cc (clang 17.0.0 \"Apple clang version 17.0.0 (clang-1700.6.4.2)\")\nC linker for the host machine: cc ld64 1230.1\nHost machine cpu family: aarch64\nHost machine cpu: aarch64\nProgram git found: YES (/usr/bin/git)\nChecking for function \"realpath\" : YES \nChecking for function \"usleep\" : YES \nChecking for function \"gettimeofday\" : YES \nChecking for function \"strnlen\" : YES \nChecking for function \"strndup\" : YES \nChecking for function \"mallinfo\" : NO \nChecking for function \"mallinfo2\" : NO \nHas header \"arpa/inet.h\" : YES \nHas header \"elf.h\" : NO \nHas header \"fcntl.h\" : YES \nHas header \"inttypes.h\" : YES \nHas header \"linux/pci.h\" : NO \nHas header \"linux/spi/spidev.h\" : NO \nHas header \"malloc.h\" : NO \nHas header \"netdb.h\" : YES \nHas header \"netinet/in.h\" : YES \nHas header \"netinet/tcp.h\" : YES \nHas header \"poll.h\" : YES \nHas header \"stdbool.h\" : YES \nHas header \"strings.h\" : YES \nHas header \"sys/ioctl.h\" : YES \nHas header \"sys/mman.h\" : YES \nHas header \"sys/param.h\" : YES \nHas header \"sys/select.h\" : YES \nHas header \"sys/socket.h\" : YES \nHas header \"sys/stat.h\" : YES \nHas header \"sys/sysctl.h\" : YES \nHas header \"sys/time.h\" : YES \nHas header \"sys/types.h\" : YES \nHas header \"unistd.h\" : YES \n\nmeson.build:118:3: ERROR: C symbol environ not found in header unistd.h","commit_id":"c5af9116bcaccc6a4713b1e6e1e191035af10d41"},{"author":{"_account_id":1000853,"name":"zapb","display_name":"Marc Schink","email":"dev@zapb.de","username":"zapb"},"change_message_id":"28facf9d282e56c7bf22435ad1120c56e4355f66","unresolved":false,"context_lines":[],"source_content_type":"","patch_set":4,"id":"bcc5ca8a_4a2dca55","updated":"2026-03-23 20:24:09.000000000","message":"Cross-compiling with Meson is straightforward.
