Makefile c

Este artigo irá demonstrar vários métodos de como usar o Makefile em C++.Use Makefile para compilar um programa de vários arquivos facilmente em C++Makefile é o nome do arquivo que descreve a relação entre os arquivos-fonte do programa e os cabeçalhos a serem compilados. Este arquivo é usado pelo utilitário make que é invocado na linha de comando e atua como um mini sistema de compilação para o projeto de código. Note, porém, que make não se limita à linguagem de programação e até mesmo à compilação do programa, pois pode ser utilizado em cenários onde os arquivos precisam ser atualizados com base nas modificações feitas nos arquivos relativos. As relações são representadas pelo conjunto de regras que descrevem as ações específicas. O trecho a seguir mostra a estrutura de uma regra típica. Um target é comumente um nome para os arquivos executáveis ​​ou de objeto. Os prerequisites geralmente são arquivos de entrada que são necessários para a saída do arquivo de destino. Uma recipe é uma ação conduzida pelo make, e eles são recuados com a guia em cada nova linha. Lembre-se de que make verifica o arquivo chamado makefile ou Makefile se ele existe no diretório de trabalho atual.target: prerequisites recipeAs regras são a parte principal do Makefile, pois são a única parte necessária. O exemplo a seguir demonstra a estrutura simples Makefile que constrói o arquivo executável denominado program. Agora, o program tem os prerequisites - main.o e library1.o, que são arquivos-objeto produzidos a partir das regras abaixo. Ambos têm suas respectivas receitas que compilam certos pré-requisitos para obter a saída fornecida. Observe que, o comando g++ é o compilador GNU C++ que é executado como parte da receita e pode ser construído com os argumentos usuais de linha de comando.program : main.o library1.o g++ -o program main.o library1.omain.o : main.cpp header1.h g++ -c main.cpplibrary1.o : library1.cpp library1.h g++ -c library1.cppOutra característica do Makefile são as variáveis ​​que se comportam de forma semelhante às expressões macro do pré-processador C++. Ou seja, podemos definir apelidos de nome para strings que aparecem no arquivo várias vezes e colocar os nomes das variáveis. Por exemplo, o próximo fragmento mostra a variável OBJ definida no início do arquivo e inclui pré-requisitos de programa que se repetem na primeira regra. Observe, porém, que as variáveis ​​são mais eficientes quando strings muito mais longas são substituídas.OBJ = main.o library1.oprogram : $(OBJ) g++ -o program $(OBJ)main.o : main.cpp header1.h g++ -c main.cpplibrary1.o : library1.cpp library1.h g++ -c library1.cppAlém disso, podemos definir outras variáveis ​​que podem representar sinalizadores de compilador ou linker, geralmente usados ​​em vários locais no Makefile. Assim, quando o projeto é grande, e o Makefile fica maior, é mais fácil modificar uma

Table des matièresIntroductionWinAVR n'est pas juste un logiciel, c'est un pack regroupant plusieurs outils indispensables à la programmation C.Il intègre le compilateur AVR-GCC, AVR-libc: les librairies essentielles de AVR-GCC, AVR-as: l'assembleur, AVRdude : l'interface de programmation, AVRice : l'interface de programmation ICE, AVR-gdb: le débugeur, programmers notepad : l'éditeur et plein d'autresCe pack a été fait pour être utilisé uniquement sous Windows.Télécharger WinAVRMakefilesLe Makefile est un fichier qui se met dans le même répertoire que votre programme pour définir les “règles” de compilation.Un makefile d'exemple se trouve dans le répertoire C:\WinAVR\sample\Il est un impératif d'avoir ce fichier dans le répertoire contenant le source de votre programme.Vous pouvez aussi créer un fichier makefile avec l'assistant MFile founit dans WinAVR. Il suffira de choisir vos différentes options dans le menu Makefile et d'enregistrer le fichier dans le répertoire de votre projet.La compilation se fait grâce à la commande make all ex : c:\test\make all test.c si vous n'avez pas de makefile dans le répertoire vous aurez une erreur du type :make.exe: *** No rule to make target 'all '. Stop.La commande make peut s'exécuter avec plusieurs paramètres All, clear, coff , extcoff, programm, fichier.sall: est le mode par défaut, il compile le fichier et crée le .hex.clear: supprime en plus tous les fichiers temporaires.coff: crée un fichier au format COFF pour la simulation avec AVRSTUDIO jusqu'à la version 4.06.extcoff: comme coff sauf que c'est pour Avrstudio à partir de la version 4.07programm: Fait le transfère du .hex dans le µcontrôleur grâce à avrdude, qu'il faut configurer avant.fichier.s: Si vous tapez make test.S le compilateur générera juste le fichier AssembleurEdition et configuration de MakefileFaite un copie avant tout du makefile qui se trouve dans C:\WinAVR\sample\ dans un répertoire de test comme … c:\test\ :) pour être sûr de ne pas modifier l'original par inadvertance.Pour l'éditer, utilisez “Programmers Notepad2” qui se trouve (depuis que vous avez fait l'installation) dans c:\WinAVR\pn\pn.exe où plus simple cliquez sur le raccourcis qui se trouve normalement sur le bureau “Programmers Notepad [WinAVR]”# MCU nameUne fois ouvert allez à la ligne # MCU name et choisisez le microcontroleur que vous allez utiliser en modifiant MCU = atmega128 par MCU = at90s8535 pour un 8535 ou at90s2313 at90s8515 atmega8 attiny22 etc etc.# Output format. (can be srec, ihex, binary)C'est le format final du fichier à charger dans le micro par defaut laissez FORMAT = ihex# Target file name (without extension).C'est le nom de votre fichier.c mais sans le .c, dans notre exemple, notre fichier est test.c donc on remplacera par TARGET = test# List C source files here. (C dependencies are automatically generated.)Ici vous pouvez rajouter d'autres fichiers .c à compiler en même temps.ex : SRC = $(TARGET).c foo.cCompilera en même temps le fichier foo.c.Dans la derniere version il y a apparemment un bug (si s'en n'est pas un, merci de me corriger)Vous avez :# List C source files here. (C dependencies are automatically generated.)SRC =# List C++ source files here. (C dependencies are automatically generated.)CPPSRC = main.cppqu'il faut remplacer par

With the source file. On my system this was done as follows: [markwill@oel02 proctest]$ cp $ORACLE_HOME/sdk/demo/demo_proc_ic.mk . I use VIM to edit the file. Of course you can use whatever editor you wish. [markwill@oel02 proctest]$ vi demo_proc_ic.mk The important part is listed in the "NOTES" section in the Makefile: # NOTES: # 1. Please change "cc/CC" and the "InstantClient directories" to point to # appropiate locations on your machine before using this makefile. Because the CC and cc entries are already correct, I did not alter them. I did, however, change the Instant Client directory entries as follows: # InstantClient Directories. ICSDKHOME=$(ORACLE_HOME)/sdk/ ICLIBHOME=$(ORACLE_HOME)/ By using the ORACLE_HOME environment variable (which is set in my oic11.env file) in the Makefile I do not need to hard-code the actual path. Before building the sample, take a minute or two to review the Makefile comments. I build the sample using the following command-line: [markwill@oel02 proctest]$ make -f demo_proc_ic.mk build PROCFLAGS="common_parser=yes" \ > EXE=proctest OBJS="proctest.o" Notice how PROCFLAGS is used to pass the "common_parser=yes" to the proc binary (i.e the Pro*C program itself). The EXE option determines the name of the binary executable produced and the OBJS option determines what object files are needed. In this case the options are simple, but larger and more complex projects likely use more than a single object file and possibly other Pro*C options. Once the build has completed test the application: [markwill@oel02 proctest]$ ./proctest 10, Jennifer Whalen, 4400, 1 20, Michael Hartstein, 13000, 1 20, Pat Fay, 6000, 2 [ snip ] 100, Nancy Greenberg, 12000, 1 100, Daniel Faviet, 9000, 2 100, John Chen, 8200, 3 110, Shelley Higgins, 12000, 1 110, William Gietz, 8300, 2 [markwill@oel02 proctest]$ One final addition I make to the Makefile is creating a new target called "dust".

Get MTTY example running?Open either the Makefile or Mttty.mak. They are there.What do you mean with open the Makefile? How can I do that with Visual C++ so that I can compile it afterwards? How does VC++ recognize make files?ThanksDanielJust go file|open project, browse to the directory, select makefile(*.mak) from the file type combobox, it's right there.Follow what byang said. You can even choose "All Files (*.*)" so that you can select Makefile or Mttty.mak.After that, .dsp and .dsw files will be generated for you.membershipCreate a free account to see this answerSigning up is free and takes 30 seconds. No credit card required.Hallo jkr(Gruesse nach Heilbronn...)I gave that up... The reason is that thread programming is not familiar to me... There would be too much effort involved if I write my own stuff. So, now I'm looking for some existing reliable win32 serial port communication code.This serial part is only a little part of my project and I just don't have the time to do more research for it. I looked again at my code and I just don't understand why it doesn't work the way it is supposed to. That class (CSerialPort) has exactly the functionality I'm looking for, but as you know, there's something wrong...Anyway, thanks a lot for your help!!!Gruesse aus New YorkDanielPS: I guess, I have to look at the mtty example, although it's C code and too big for my purposes :-(Have you solved the problem?Yes I solved it... Answer it and I can give you the points...I had already answered it. Thank you.
