From f7adba41820bbcfb86349c2ebc529f626d2313e3 Mon Sep 17 00:00:00 2001 From: Sibi Siddharthan Date: Fri, 26 Jun 2020 16:11:36 +0000 Subject: cmake: support for building git on windows with mingw This patch facilitates building git on Windows with CMake using MinGW NOTE: The funtions unsetenv and hstrerror are not checked in Windows builds. Reasons NO_UNSETENV is not compatible with Windows builds. lines 262-264 compat/mingw.h compat/mingw.h(line 25) provides a definition of hstrerror which conflicts with the definition provided in git-compat-util.h(lines 733-736). To use CMake on Windows with MinGW do this: cmake `relative-path-to-srcdir` -G "MinGW Makefiles" Signed-off-by: Sibi Siddharthan Signed-off-by: Junio C Hamano --- contrib/buildsystems/CMakeLists.txt | 117 +++++++++++++++++++++++++++++------- 1 file changed, 94 insertions(+), 23 deletions(-) (limited to 'contrib') diff --git a/contrib/buildsystems/CMakeLists.txt b/contrib/buildsystems/CMakeLists.txt index 2768ee5b71..2d7c0ed88e 100644 --- a/contrib/buildsystems/CMakeLists.txt +++ b/contrib/buildsystems/CMakeLists.txt @@ -42,6 +42,10 @@ cmake_minimum_required(VERSION 3.14) set(CMAKE_SOURCE_DIR ${CMAKE_CURRENT_LIST_DIR}/../..) find_program(SH_EXE sh) +if(NOT SH_EXE) + message(FATAL_ERROR "sh: shell interpreter was not found in your path, please install one." + "On Windows, you can get it as part of 'Git for Windows' install at https://gitforwindows.org/") +endif() #Create GIT-VERSION-FILE using GIT-VERSION-GEN if(NOT EXISTS ${CMAKE_SOURCE_DIR}/GIT-VERSION-FILE) @@ -65,7 +69,9 @@ project(git VERSION ${git_version} LANGUAGES C) + #TODO gitk git-gui gitweb +#TODO Enable NLS on windows natively #TODO Add pcre support #macros for parsing the Makefile for sources and scripts @@ -104,6 +110,7 @@ find_package(EXPAT) find_package(Iconv) find_package(Intl) + if(NOT Intl_FOUND) add_compile_definitions(NO_GETTEXT) if(NOT Iconv_FOUND) @@ -125,6 +132,14 @@ if(Intl_FOUND) include_directories(SYSTEM ${Intl_INCLUDE_DIRS}) endif() + +if(WIN32) + find_program(WINDRES_EXE windres) + if(NOT WINDRES_EXE) + message(FATAL_ERROR "Install windres on Windows for resource files") + endif() +endif() + find_program(MSGFMT_EXE msgfmt) if(NOT MSGFMT_EXE) message(WARNING "Text Translations won't be build") @@ -156,11 +171,35 @@ add_compile_definitions(PAGER_ENV="LESS=FRX LV=-c" BINDIR="bin" GIT_BUILT_FROM_COMMIT="") -set(FALLBACK_RUNTIME_PREFIX /home/$ENV{USER}) -add_compile_definitions(FALLBACK_RUNTIME_PREFIX="${FALLBACK_RUNTIME_PREFIX}") +if(WIN32) + set(FALLBACK_RUNTIME_PREFIX /mingw64) + add_compile_definitions(FALLBACK_RUNTIME_PREFIX="${FALLBACK_RUNTIME_PREFIX}") +else() + set(FALLBACK_RUNTIME_PREFIX /home/$ENV{USER}) + add_compile_definitions(FALLBACK_RUNTIME_PREFIX="${FALLBACK_RUNTIME_PREFIX}") +endif() + + +#Platform Specific +if(CMAKE_SYSTEM_NAME STREQUAL "Windows") + include_directories(${CMAKE_SOURCE_DIR}/compat/win32) + add_compile_definitions(HAVE_ALLOCA_H NO_POSIX_GOODIES NATIVE_CRLF NO_UNIX_SOCKETS WIN32 + _CONSOLE DETECT_MSYS_TTY STRIP_EXTENSION=".exe" NO_SYMLINK_HEAD UNRELIABLE_FSTAT + NOGDI OBJECT_CREATION_MODE=1 __USE_MINGW_ANSI_STDIO=0 + USE_NED_ALLOCATOR OVERRIDE_STRDUP MMAP_PREVENTS_DELETE USE_WIN32_MMAP + UNICODE _UNICODE HAVE_WPGMPTR ENSURE_MSYSTEM_IS_SET) + list(APPEND compat_SOURCES compat/mingw.c compat/winansi.c compat/win32/path-utils.c + compat/win32/pthread.c compat/win32mmap.c compat/win32/syslog.c + compat/win32/trace2_win32_process_info.c compat/win32/dirent.c + compat/nedmalloc/nedmalloc.c compat/strdup.c) + set(NO_UNIX_SOCKETS 1) + +elseif(CMAKE_SYSTEM_NAME STREQUAL "Linux") + add_compile_definitions(PROCFS_EXECUTABLE_PATH="/proc/self/exe" HAVE_DEV_TTY ) + list(APPEND compat_SOURCES unix-socket.c) +endif() -add_compile_definitions(PROCFS_EXECUTABLE_PATH="/proc/self/exe" HAVE_DEV_TTY ) -list(APPEND compat_SOURCES unix-socket.c) +set(EXE_EXTENSION ${CMAKE_EXECUTABLE_SUFFIX}) #header checks check_include_file(libgen.h HAVE_LIBGEN_H) @@ -223,7 +262,12 @@ endif() #function checks set(function_checks strcasestr memmem strlcpy strtoimax strtoumax strtoull -
