From: Guus Sliepen Date: Sun, 11 Dec 2022 11:47:47 +0000 (+0100) Subject: Initial support for CMake. X-Git-Url: https://git.meshlink.io/?a=commitdiff_plain;h=917bcedfc76294050763a5bd5077f5b4e44d62fe;p=meshlink Initial support for CMake. This supports building and installing the library, as well as running part of the test suite (blackbox tests are not built yet). So far it has only been tested on Linux. --- diff --git a/CMakeLists.txt b/CMakeLists.txt new file mode 100644 index 00000000..ce082569 --- /dev/null +++ b/CMakeLists.txt @@ -0,0 +1,28 @@ +project(meshlink-tiny) +cmake_minimum_required(VERSION 3.12) + +set(THREADS_PREFER_PTHREAD_FLAG ON) +find_package(Threads REQUIRED) + +include(CheckSymbolExists) +include(CheckIncludeFile) +include(CTest) + +#add_definitions(-D_GNU_SOURCE) +#add_definitions(-D_POSIX_C_SOURCE=200112L) +set(CMAKE_REQUIRED_DEFINITIONS -D_GNU_SOURCE) +#list(APPEND CMAKE_REQUIRED_DEFINITIONS -D_GNU_SOURCE) +#add_compile_definitions(_GNU_SOURCE) +#string(APPEND CMAKE_C_FLAGS "-D_GNU_SOURCE") + +check_symbol_exists(setns "sched.h" HAVE_SETNS) +check_symbol_exists(strsignal "string.h" HAVE_STRSIGNAL) +check_symbol_exists(asprintf "stdio.h" HAVE_ASPRINTF) +check_symbol_exists(pselect "sys/select.h" HAVE_PSELECT) +check_include_file(stdatomic.h HAVE_STDATOMIC_H) +configure_file(cmake_config.h.in config.h) +include_directories(${CMAKE_CURRENT_BINARY_DIR}/src) + +add_subdirectory(src) +enable_testing() +add_subdirectory(test) diff --git a/cmake_config.h.in b/cmake_config.h.in new file mode 100644 index 00000000..c4854c36 --- /dev/null +++ b/cmake_config.h.in @@ -0,0 +1,10 @@ +#define _GNU_SOURCE 1 +#define __USE_BSD 1 +#define _POSIX_C_SOURCE 200809L +#define _DARWIN_C_SOURCE 1 + +#cmakedefine HAVE_ASPRINTF +#cmakedefine HAVE_PSELECT +#cmakedefine HAVE_SETNS +#cmakedefine HAVE_STDATOMIC_H +#cmakedefine HAVE_STRSIGNAL diff --git a/src/CMakeLists.txt b/src/CMakeLists.txt new file mode 100644 index 00000000..1b47d5b4 --- /dev/null +++ b/src/CMakeLists.txt @@ -0,0 +1,76 @@ +#include(GenerateExportHeader) +#generate_export_header(meshlink BASE_NAME meshlink) + +add_library(meshlink SHARED + adns.c + buffer.c + chacha-poly1305/chacha-poly1305.c + chacha-poly1305/chacha.c + chacha-poly1305/poly1305.c + conf.c + connection.c + crypto.c + devtools.c + discovery.c + dropin.c + ed25519/add_scalar.c + ed25519/ecdh.c + ed25519/ecdsa.c + ed25519/ecdsagen.c + ed25519/fe.c + ed25519/ge.c + ed25519/key_exchange.c + ed25519/keypair.c + ed25519/sc.c + ed25519/seed.c + ed25519/sha512.c + ed25519/sign.c + ed25519/verify.c + edge.c + event.c + graph.c + hash.c + list.c + logger.c + mdns.c + meshlink.c + meta.c + net.c + net_packet.c + net_setup.c + net_socket.c + netutl.c + node.c + prf.c + protocol.c + protocol_auth.c + protocol_edge.c + protocol_key.c + protocol_misc.c + route.c + splay_tree.c + sptps.c + submesh.c + utcp-test.c + utcp.c + utils.c + xoshiro.c +) + +set(MESHLINK_PUBLIC_HEADERS + meshlink.h + meshlink++.h +) + +target_compile_features(meshlink PUBLIC c_std_11) +target_link_libraries(meshlink PRIVATE Threads::Threads) +set_target_properties(meshlink PROPERTIES PUBLIC_HEADER "${MESHLINK_PUBLIC_HEADERS}") +set_property(TARGET meshlink PROPERTY C_VISIBILITY_PRESET hidden) +set_property(TARGET meshlink PROPERTY C_STANDARD 11) + +include(GNUInstallDirs) +install(TARGETS meshlink + LIBRARY + LIBRARY DESTINATION ${CMAKE_INSTALL_LIBDIR} + PUBLIC_HEADER DESTINATION ${CMAKE_INSTALL_INCLUDEDIR} +) diff --git a/src/conf.c b/src/conf.c index db91d5fb..13ee7e1b 100644 --- a/src/conf.c +++ b/src/conf.c @@ -510,7 +510,7 @@ bool main_config_lock(meshlink_handle_t *mesh, const char *lock_filename) { fcntl(fileno(mesh->lockfile), F_SETFD, FD_CLOEXEC); #endif -#ifdef HAVE_MINGW +#ifdef _WIN32 // TODO: use _locking()? #else diff --git a/src/crypto.c b/src/crypto.c index 3244a0b4..097f9d2b 100644 --- a/src/crypto.c +++ b/src/crypto.c @@ -23,7 +23,7 @@ //TODO: use a strict random source once to seed a PRNG? -#ifndef HAVE_MINGW +#ifndef _WIN32 static int random_fd = -1; diff --git a/src/devtools.h b/src/devtools.h index 78e36428..8e56c9e0 100644 --- a/src/devtools.h +++ b/src/devtools.h @@ -20,6 +20,10 @@ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. */ +#ifndef MESHLINK_EXPORT +#define MESHLINK_EXPORT __attribute__((visibility("default"))) +#endif + /// \file devtools.h /** This header files declares functions that are only intended for debugging and quality control. * They are not necessary for the normal operation of MeshLink. @@ -71,7 +75,7 @@ struct devtool_edge { * value.
