Jigsaw Thermometer Sudoku with no given numbers Should the ends of sistered joists be supported by the framing below? I want to detect the OS and issue the right commands automatically. I want to autodetect system architecture, when i compile my program under freebsd and i want 2 includes for x64 and x32 but don't work, i tried like this : ifeq ($(uname -a),i386) INCDIR += -I. Makefile - Function to check empty environment variables. The WIN32, APPLE, UNIX, etc. Each time I modify some of the files, I pack all of them in a program. @syam : The timestamp is determined by the filesystem/OS, not by make. It builds fine, and invokes the make (not clang) - but some of the red squiggles in the C code are false positives, due to using clang and not arm-none-eabi-hcc. I think you might be confused. I want to detect which operating system my . For example make clean command on Windows looks like: del $(DESTDIR_TARGET) But on Linux: rm Detect operating system in Makefile. Copy link Contributor Author. See 6. The problem is that some commands are I want the Makefile to detect whether it operates on Windows or Linux. /. Thank you. asked Aug 14, 2019 at 13:14. I am now doubting that there is a portable way to achieve your goal using just a Makefile (i. Or shell in combination with notdir, if you need not absolute path: current_dir = $(notdir $(shell pwd)). It works in shell and aims to correctly recognise distributions like Alternatively, for a convenience, a shorten and memorable version of the above URL can be used which is tiny. @jviotti Perhaps uname -m would work on all linux distributions (would be the best case scenario). OS_NAME := $(shell uname -s | tr A-Z a-z) OS_ARCH := $(shell uname -m | tr A-Z a-z) os: @echo "" . Other than APPLE, I couldn't find any strong alternatives. The OS can be detected automatically but it takes a lot of arcane tricks, there's no one simple way to do it that quickly gives you an answer for every OS. You may also want to set -e option (aka --environments-override) on, and your environment variables will override assignments made into makefile (unless these Thus, for maximum portability and maintainability, you should focus on that difference and make the conditional compilation dependent upon detecting the difference rather than dependent upon the OS itself. make --eval='print-tests: @echo TESTS $(TESTS) ' print-tests You can insert the required TAB character in the command line Makefile with OS detect. The shell function. abernier abernier. The compiled binary is placed in If you don't want to modify the Makefile itself, you can use --eval to add a new target, and then execute the new target, e. Reload to refresh your session. h file automatically. I gave up on doing this in make language, so I coded it in Python, and want to embed the code into Makefile to set variable. The whitespace at the beginning of each shell command is a TAB character, not spaces. Why `git checkout -` works differently in a Makefile? 1. o that was made for the first is wrong for the second and should not be used. h>, but __Linux__ only provides here <ncursesw/curses. However, I can't get it to work so that I can capture the results of the Powershell command within the Makefile to a variable. regardless of whether I've edited any of the files involved in generating that object file. However for Windows to work we need this. Sign in Product GitHub Copilot. This is why people use makefile generators or use newer build systems. CMAKE_HOST_SYSTEM_PROCESSOR is generally completely useless - for example it returns "i386" on a 64-bit OS X system and probably other less than useful values on other systems as To have a target depend on changes to a makefile you need to list the makefile(s) as prerequisites like anything else (i. 1 IBM-L3F3936 1. Uname prints the system name, which you can use to determine the OS. Detect OS type using the USB enumeration. I could run a Darwin system and have it NOT be OS X. make: `some/obj/file. Learn more about bidirectional Unicode characters. I'ld like to automatically detect (using #ifdef) whether I'm building using XCode or using make under Darwin. CMake doesn't detect changed files at all. The tilde character always stands for the user's home directory (this is true on POSIX systems as well). exe is being run on (notice that on MacOSX executable files are traditionally not suffixed with . But from there, you cannot set a variable that applies elsewhere in the Makefile. How in 'make' check the current operating system is? 1. I have read a lot of these sorts of struggles but none seem to be what I need. But I don't know whether it is the case. The problem is that there are three different commands for md5sum command: md5sum. 10 Variables from the Environment. Is there a better or cleaner way than the following %. PHONY is likely more correct and more what you want. __APPLE__ Also used for I have the following code: ifeq ($(OS),Windows_NT) OS_POD+=win else UNAME_S := $(shell Skip to main content. Detect the operating system using two simple tricks: First the environment variable OS; Then the uname command; ifeq ($(OS),Windows_NT) # is Windows_NT on XP, 2000, 7, Vista, 10 detected_OS := Windows else detected_OS := $(shell uname) # same as "uname The following Makefile uses $(OS) to determine the OS and uses ifeq to either assign a. c cc -o main main. h>. The problem is that some commands are different in windos than in unix. 0. The makefile includes instructions for controlling a workflow, typically to compile software, Customizing Makefile for Operating System. %. h and this line in your . g. 1. rm $(find . ifeq '$(findstring ;,$(PATH))' ';' UNAME := Windows else UNAME := $(shell uname 2>/dev/null || echo Unknown) endif The UNAME variable is set to Linux, Windows or Unknown. Support for bom See the docs\ directory for more detailed information on: - building Snowdrop OS - extending Snowdrop OS with your own kernel services and apps - a list of the service interrupts provided by the kernel to apps - my daily development log, kept as I developed Snowdrop OS - a useful listing of keyboard scan codes - BASIC documentation - x86 assembler documentation - version Apple Footer. – Roland Weber. Make sure that the -L option appears ahead of the -l option; the order of options in linker command lines does matter, especially with static libraries. This functionality can be used to build a cross-platform Makefile Hi, I do "touch poub. 6, bom members have been added to the DetectObj structure. It is helpful to ensure that a makefile is portable across operating systems, or at Modern CMake Way. -type f -executable) with the dollar doubled as Make itself uses $. If you're writing a Mac app, the host and target would both be OS X. releng/detect-arch. ricww ndvbzh vna ruyvs ept bxvan wxyml tah yan wdud
