From d5c31f6d99a3d02c8b0efba13e1a1e82e0e36f96 Mon Sep 17 00:00:00 2001 From: Hilton Chain <hako@ultrarare.space> Date: Fri, 29 Nov 2024 14:13:46 +0800 Subject: [PATCH] Fix RUNPATH issue. Add needed libraries and libc to RUNPATH when CROSS_LIBRARY_PATH or LIBRARY_PATH is set. --- lib/std/Build/Step/Compile.zig | 3 +++ src/link/Elf.zig | 14 ++++++++++++++ src/main.zig | 34 +++++++++++++++++++++++++++++++++- 3 files changed, 50 insertions(+), 1 deletion(-) diff --git a/lib/std/Build/Step/Compile.zig b/lib/std/Build/Step/Compile.zig index 1dd444abf2..df7f4a56db 100644 --- a/lib/std/Build/Step/Compile.zig +++ b/lib/std/Build/Step/Compile.zig @@ -778,6 +778,9 @@ fn runPkgConfig(compile: *Compile, lib_name: []const u8) !PkgConfigResult { try zig_cflags.appendSlice(&[_][]const u8{ "-D", macro }); } else if (mem.startsWith(u8, arg, "-D")) { try zig_cflags.append(arg); + } else if (mem.startsWith(u8, arg, "-Wl,-rpath=")) { + const dir = arg["-Wl,-rpath=".len..]; + try zig_libs.appendSlice(&[_][]const u8{ "-L", dir }); } else if (b.debug_pkg_config) { return compile.step.fail("unknown pkg-config flag '{s}'", .{arg}); } diff --git a/src/link/Elf.zig b/src/link/Elf.zig index 608ff2fe3a..2b9fe803fd 100644 --- a/src/link/Elf.zig +++ b/src/link/Elf.zig @@ -1037,6 +1037,13 @@ fn dumpArgvInit(self: *Elf, arena: Allocator) !void { try argv.appendSlice(gpa, &.{ "-rpath", rpath }); } + if (std.zig.system.NativePaths.isGuix(arena) and comp.config.link_libc and comp.config.link_mode == .dynamic) { + if (self.base.comp.libc_installation) |libc_installation| { + try argv.append(gpa, "-rpath"); + try argv.append(gpa, libc_installation.crt_dir.?); + } + } + try argv.appendSlice(gpa, &.{ "-z", try std.fmt.allocPrint(arena, "stack-size={d}", .{self.base.stack_size}), @@ -1857,6 +1864,13 @@ fn linkWithLLD(self: *Elf, arena: Allocator, tid: Zcu.PerThread.Id, prog_node: s try argv.appendSlice(&.{ "-rpath", rpath }); } + if (std.zig.system.NativePaths.isGuix(arena) and comp.config.link_libc and link_mode == .dynamic) { + if (self.base.comp.libc_installation) |libc_installation| { + try argv.append("-rpath"); + try argv.append(libc_installation.crt_dir.?); + } + } + for (self.symbol_wrap_set.keys()) |symbol_name| { try argv.appendSlice(&.{ "-wrap", symbol_name }); } diff --git a/src/main.zig b/src/main.zig index 79493aa624..505bb7570a 100644 --- a/src/main.zig +++ b/src/main.zig @@ -3901,7 +3901,7 @@ fn createModule( create_module.want_native_include_dirs = true; } - if (create_module.each_lib_rpath orelse resolved_target.is_native_os) { + if (create_module.each_lib_rpath orelse false) { try create_module.rpath_list.ensureUnusedCapacity(arena, create_module.lib_directories.items.len); for (create_module.lib_directories.items) |lib_directory| { create_module.rpath_list.appendAssumeCapacity(lib_directory.path.?); @@ -3976,6 +3976,28 @@ fn createModule( else => {}, }; + if (std.zig.system.NativePaths.isGuix(arena)) { + for (create_module.link_inputs.items) |link_input| { + if (link_input.path()) |lib| { + const lib_name = lib.sub_path; + if (Compilation.classifyFileExt(lib_name) == .shared_library) { + if (fs.path.isAbsolute(lib_name)) { + const lib_dir_path = fs.path.dirname(lib_name).?; + try create_module.rpath_list.append(arena, lib_dir_path); + continue; + } + for (create_module.lib_directories.items) |lib_dir| { + const lib_dir_path = lib_dir.path.?; + if (try libPathExists(arena, lib_dir_path, lib_name)) { + try create_module.rpath_list.append(arena, lib_dir_path); + break; + } + } + } + } + } + } + create_module.resolved_options = Compilation.Config.resolve(create_module.opts) catch |err| switch (err) { error.WasiExecModelRequiresWasi => fatal("only WASI OS targets support execution model", .{}), error.SharedMemoryIsWasmOnly => fatal("only WebAssembly CPU targets support shared memory", .{}), @@ -7495,3 +7517,13 @@ fn addLibDirectoryWarn2( .path = path, }); } + +fn libPathExists(arena: Allocator, lib_dir_path: []const u8, lib_name: []const u8) !bool { + const lib_path = try std.fmt.allocPrint(arena, "{s}{s}{s}", .{ + lib_dir_path, + fs.path.sep_str, + lib_name, + }); + fs.cwd().access(lib_path, .{}) catch return false; + return true; +} -- 2.46.0
