I am trying to build my oscilloscope project using build.zig and cmake. I can compile and run using cmake:
cmake_minimum_required(VERSION 3.16)
# set the output directory for built objects.
# This makes sure that the dynamic library goes into the build directory automatically.
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY "${CMAKE_BINARY_DIR}/$<CONFIGURATION>")
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY "${CMAKE_BINARY_DIR}/$<CONFIGURATION>")
# prevent installing to system directories.
set(CMAKE_INSTALL_PREFIX "${CMAKE_BINARY_DIR}" CACHE INTERNAL "")
# Declare the project
project(sdl-synth)
set(SDL_SHARED ON)
add_executable(v1)
# Add your sources to the target
target_sources(v1
PRIVATE
v1/main.cpp
imgui/imgui.cpp
imgui/imgui_demo.cpp
imgui/imgui_draw.cpp
imgui/imgui_tables.cpp
imgui/imgui_widgets.cpp
imgui/backends/imgui_impl_sdl3.cpp
imgui/backends/imgui_impl_sdlrenderer3.cpp
implot/implot.cpp
implot/implot.h
implot/implot_internal.h
implot/implot_demo.cpp
implot/implot_items.cpp
)
target_include_directories(v1 PRIVATE imgui/ imgui/backends/ implot/ v1/ )
target_compile_definitions(v1 PRIVATE SDL_MAIN_USE_CALLBACKS)
# Configure SDL by calling its CMake file.
# we use EXCLUDE_FROM_ALL so that its install targets and configs don't
# pollute upwards into our configuration.
add_subdirectory(SDL)
# Link SDL to our executable. This also makes its include directory available to us.
target_link_libraries(v1 PUBLIC
SDL3::SDL3 # If using satelite libraries, SDL must be the last item in the list.
)
But when I run my app built with build.zig it errors out saying no video driver are availlable:
const builtin = @import("builtin");
const std = @import("std");
pub fn build(b: *std.Build) anyerror!void {
// Get the default optimization level.
const optimize = b.standardOptimizeOption(.{});
// Get the default target, this is the host computer and os.
const target = b.standardTargetOptions(.{
.default_target = std.Target.Query{
.os_tag = builtin.target.os.tag,
},
});
const run = b.step("run", "Run v1");
const sdl_dep = b.dependency("sdl", .{
.target = target,
.optimize = optimize,
});
const sdl_lib = sdl_dep.artifact("SDL3");
const v1_zig_module = b.addModule("v_1_z", .{
.root_source_file = b.path("v1/generator.zig"),
.target = target,
.optimize = optimize,
});
const v1_zig_lib = b.addObject(.{
.root_module = v1_zig_module,
.name = "v_1_z_lib",
});
const v1_cpp_module = b.addModule("v_1", .{
.target = target,
.optimize = optimize,
.link_libcpp = true,
});
v1_cpp_module.addObject(v1_zig_lib);
v1_cpp_module.linkLibrary(sdl_lib);
const files: []const []const u8 = &.{

const flags: []const []const u8 = &.{

};
v1_cpp_module.addCSourceFiles(.{
.files = files,
.flags = flags,
.language = .cpp,
.root = null,
});
v1_cpp_module.addIncludePath(b.path("v1/"));
v1_cpp_module.addIncludePath(b.path("imgui/"));
v1_cpp_module.addIncludePath(b.path("imgui/backends/"));
v1_cpp_module.addIncludePath(b.path("implot/"));
const v1_exe = b.addExecutable(.{

.name = "v_1",
});
b.installArtifact(v1_exe);
const runExe = b.addRunArtifact(v1_exe);
run.dependOn(&runExe.step);
}
I am on ubuntu Noble, using zig 0.15.2.
