Library: ALLEGRO.h

Am cautat biblioteca allegro f mult(am inteles ca e speciala pentru jocuri) dar totusi nu o gasesc, am cautat pe yahoo si google ,am gasit ceva dar nu cred ca am gasit ce trebuie   ...
Si a 2-a intrebare este cum o "instalez" in VC++?  
http://www.allegro.com :un link dintre multe alte link-uri ...dar totusi nu ma descurc.
.
Multumesc anticipat .

cred ca nu stii sa cauti cu google: http://www.talula.demon.co.uk/allegro/ , http://www.google.co...c &btnG=Search

Nu e vorba ca nu stiu sa caut cu google , dar nu gasisem cum sa "instalez" library ...    

Cum instalez acesta biblioteca?  Am pus README-ul - nu e vorba ca nu inteleg cuvintele in engleza ci cum le inlocuiesc chestiile alea pe acolo ... am download-at de pe site http://alleg.sourceforge.net/wip.html  all420.zip.... multumesc

Va rog... am nevoie de acesta librarie !!! copiez allegro.h in VC/include/?? cum fac????
Stiu ca va enervez dar chiar nu am idee .!!!!

libraria aia trebuie sa o construiesti singur porinind de la surse.
citeste si tu acel readme.txt.

pe scurt: exista un make file pt visual studio. modifici variabila de mediu ca sa includa calea catre nmake.exe, care se afla in directorul ..\Program Files\Microsoft Visual Studio\VC6\Bin. fisierul VCVARS32.BAT din acelasi director face asta pt tine.

dupa ce variabila path e setata, executi nmake cu parametru numele fisierului make. dupa ce obtii lib-urile, in proiectul tau incluzi fisierele header, iar la linkeditare incluzi liburile.

uite aici o eroare cand compilez un simplu cod si imi da eroarea
--------------------Configuration: ex3d - Win32 Debug--------------------

Compiling...
ex3d.c
c:\program files\microsoft visual studio\vc98\include\allegro\internal\alconfig.h(64) : fatal error C1083: Cannot open include file: 'allegro/platform/astdint.h': No such file or directory
Error executing cl.exe.

ex3d.exe - 1 error(s), 0 warning(s)


this is the error ... 
I compile ex3d.c to the exemple 

why? I install 4.2.0 version

dupa cite vad ai facut o gresala, introducind fisierele in directorul standard unde e instalat Visual C++. acest lucru il poti evita foarte usor, in doua moduri: ori specifici o cale globala in Tools -> Options -> Directories ori Project settings -> C/C++ -> Category: Preprocessor -> Additional Include Directories.

atentie si la caile relative din directivele #include. dupa mesajul de eroare directorul de include trebuie sa fie parintele folderului "allegro".

asigura-te si ca acel fisier (alconfig.h) exista intr-adevar.

daca sistemul nu e setat cum trebuie, s-ar putea sa ai erori si la link-editare.

nu inteleg de ce nu ai incercat cum ti-am spus, cu makefile. rezolvai totul in consola si nici nu trebuia sa deschizi visual c++.

cum modific variabila de mediu ?
am facut cum zicea pe site-ul oficial

http://www.allegro.c...stall-msvc.html Method B

poate imi explicati si mie ca la ....noobi

u chiar nu reusesc sa fac cqa aceaesta lib sa functioneze....
"oi fi tandala"

ai scapat de o mare belea. nu mai trebuie sa compilezi tu sursele.
in varianta B librariile sint deja compilate si nu mai trebuie sa faci nimic.

fi atent cum trebuie sa fac, concret si la obiect.

1. download.
urmezi linkul tau si downloadezi din categoria Binary -> Microsoft Visual C++ 6 - zip, 7z, exe. fisierul se numeste allegro-msvc6-4.2.0.zip si il dezarhivezi intr-un folder, de exemplu: c:\allegro. dupa dezarhivare vei avea 3 subdirectoare: bin, include si lib.

2. setarea cailor pt compilare.
deschizi proiectul tau in Visual C++ si te duci in Project Settings -> Project settings -> C/C++ -> Category: Preprocessor -> Additional Include Directories. aici introduci: c:\allegro\include.

3. setarea cailor si librariilor pt linkeditare.
te duci in Project Settings -> Link -> Category: Input. in cimpul Object/library modules adaugi libraria de care ai nevoie. care librarie trebuie adaugata din cele fisiere? asta trebuie sa decizi tu. librariile cu _s sint varianta statica, adica varianta care ruleaza fara dll. apoi, alld.lib este versiunea de debug, alleg.lib este versiunea optimizata (release), iar allp.lib este versiunea cu profiling enabled. daca nu sti ce inseamna toate astea, alege pt inceput alld.lib pe care o treci in in cimpul Object/library modules.

In cimpul Additional library path mai trebuie sa adaugi: C:\allegro\lib


asta e tot. daca faci totul cum ti-am spus, n-ar trebui sa mai ai erori. daca mai intimpini greutati, revino cu mesajele de eroare.

In primul rand iti multumesc ca ma ajuti!


inainte de ce mi-ai zis tu ...
c:\documents and settings\purice\desktop\exhello.c(7) : fatal error C1083: Cannot open include file: 'allegro.h': No such file or directory
(mi se pare normal)

dupa ce mi-ai zis
Compiling...

Linking...

exhello.exe - 2 error(s), 0 warning(s)


plus de asta dupa ce ies din proiect imi dispare ce am scris la preproceser..link..etc...

daca mai compilez o data ....(dupa ce mi-au disparut alea)

END_OF_MAIN()

vezi ca n-au cum sa-ti dispara setarile, decit daca nu salvezi proiectul.

prima eroare: LIBCD.lib(crt0.obj) : error LNK2001: unresolved external symbol _main

te duci in Project Settings -> Link -> Project Options. acolo dai scroll pina intilnesti o optiune /subsistem:console pe care o schimbi in /subsystem:windows dupa care ar trebui sa-ti mearga.

daca iti continuare persista eroarea cu simbolul _main atunci creeaza un nou proiect Win32 Console si adauga acolo codul.

in legatura cu celelalte erori, poate n-ai setat corect caile in tabul Link, cum ti-am zis in postul anterior. daca nu merge incearca si cu libraria alld_s.lib.

daca tot nu merge, fa-i un zip cu tot workspace-ul si punel-l aici sa-l deschid si sa vad care sint problemele.

merge....
am facut un project win32aplication  si imi merge...
acum nu imi mai ramane dacat sa incep sa citesc tutoriale
bafta ... si inca o data multam !

salut
Am inca o problema.AM pus codul n fisier ...
problema e ca atunci cand il rulez imi iese imediat din program
si imi da

acesta este un acces ilegal la memorie cauzat de o gresala de programare.

trebuie sa rulezi in programul in debug mode, pas cu pas, pina identifici linia care da aceasta eroare. pt aceasta porneste programul cu F10. pt a urmari apelul functiilor in interiorul lor, folosesti F11. cu ocazia asta inveti comenzile debuggerului: Step Over, Step In, Step Out, Run to Cursor.

uite codul... o sa incerc sa fac ce mi-ai zis ....
bafta ....
mai intreb daca nu reusesc !

purice, urasc sa fac debug pe codul altora. doar nu crezi ca eu sau altcineva o sa-ti faca debug la codul asta. mai ales ca trebuie instalate headere, librarii, etc, etc, ... cunosti toata povestea.

mai pune si tu osul la treaba.

normal ca incerc sa fal eu sa mearga...
NU am inteles partea cu rulatul pas cu pas (cum adica ?)
mie am dat pe butoanele alea de acolo( prima data cand fac asta) si imi arata la   "END_OF_MAIN()" o nepotrivire nici nu stiu ce era aia...
Daca esti bun sa-mi zici chestia aia rulatul pas cu pas ...
numai bine
