I was wondering about a package that can be used to write and compile/run programs in different programming languages. I was also wondering how possible it is to program in Visual Basic 2010 in openSUSE if at all.
View 9 RepliesWell I have been interested in programming for a while, and just found out about Linux and Unix. I started out with Java, but now I know I bunch: Flash, C++, C and others. I was working on a mac so I made a few flash games then started to work on iPhone games. I was board one day and I found out about Unix and I thought that would be something else to try.So in an attempt to learn about Unix I have been reading different articles about it, and have heard of using different languages in one program. The article I was reading didn't give any examples, and it assumed the reader has programmed Unix before.
So how do you write programs in multiple languages, which languages would you use, and why would you want to do that?
I work on Fedora 9 and I'm unable to compile my c++ program using the make in the terminal as well as in the IDE-Anjuta.although 'make' works fine with C programs,I get an error that g++ command is not found whenever I try it with C++ programs.

View 9 Replies View RelatedActually I had a folder called Lib, in which I had a few libraries installed and configured.(MPI, PETSc, SLEPc) I accidently deleted (by rm) the contents of that folder.
Then I reinstalled MPI,PETSC,SLEPC using the same tarballs as earlier(thus, the version etc. is the same).
I already had a fortran program with many modules and subroutine files, and the corresponding makefile which used to compile and run fine. But now when I type "make" in the same directory as before, I get this: (shortened, many similar errors)
Code:
Firstly, why is mpif90 compiling my program when I didnt tell it to? In my makefile, I have specified gfortran as my compiler....nowhere have I even mentioned mpif90. Such a thing never used to occur before.
Also, if I rename file_variable.f to file_variable.f90, these errors dissappear (I understand why, but that is not the problem), but a new error comes:
Why is the new MPI installation interfering with make ? I want to go back to how things were before I stupidly broke all installations. The errors themselves are not the problem, the problem is why the new mpi installation is interfering with make.
It seems as if mpif90 has taken over make and gfortran. I suppose I didnt install it correctly, or probably I didnt uninstall the earlier one correctly.
Everything that worked earlier doesnt work suddenly. I use ubuntu 11.04 MPICH2-1.3.2
Do you know how to write programs that use electronic signatures in JAVA (although I am not pretentious about the language in any way).
When I say e-signatures I mean those USB smart cards(security tokens) that are capable of doing encryption by themselves and store securely the private key. I am particularly interested in how authentication works with a digital signature, how to sign data, and most importantly how to check that a digital certificate is valid. What do I need to store in the Database for authentication for example -- is it the serial or the Hash?

And post the fruits of my attempts at my blog (shameless plug) aswell as opening up my svn repository when I'm done. (altho i need to ask in another thread about svn permissions....)To my shame i havent ever touched C#, JavaScript, Ruby or Python, so all in all its going to be very interesting how much i screw up.Anyone have any additional ideas, or languages I'm missing or such? I was considering TCL or Haskell or Erlang at a strech, but i dont know how useful these three would be.
I want to know your opinions on the best combination of programming languages to learn if you want to learn more than one. An explanation of your choices would be real nice. I've included a multiple-choice poll that has the langauges from the Member's Choice Awards 2009 list of best programming languages on it. Please vote for your choice of languages also. It should be interesting to see what the numbers are like when people can vote this way, and choose more than one language.I'm voting for Python/C just as an "overall" opinion. It's what I'm going to learn. I've done quite a bit of reading and experimenting and this is what I've personally settled on. My opinion is just a personal "overall" opinion. You can also pick just a single language, and vote for just a single language if you think it's better to learn just one.

View 2 Replies View RelatedI am just starting to learn Linux and am interested in a career in Linux. Actually I wanna go for RHCE, which is the first step for Sys Admin..right?? Basically I do NOT want to go into programming/developing as I don't feel it's my cup of tea (and also may be it sort of boggles me). Still, from what I gather I am having confusions regarding whether I should learn any programming language for a career in Linux.
Here I am avoiding programming..and now I get to hear that Linux career uses programming..That's sort of frustrating...My friend told me I need to "master" C. Do I need to learn some programming language?? If yes, then to how much extent?
I have recently graduated from uni and during my time there I have developed an interest in HDL, specifically Verilog. As my current job doesn't lend itself to doing anything in verilog so I decided to keep myself sharp by designing a 32 bit processor that is similar to (but not the same as) the MIPS processor it will certainly be RISC. While starting work on it I have decided to start a blog detailing what I have done including the source file as I am entering my work into the wide world I think it needs a licence but I am not looking to make any money or even to derive any fame from what I'm doing. Like I said the main reason to do it is to keep me active in using HDLs.
I hope to gain from the blog suggestions for alternative(better) ways to do what I am doing, for people to use what I have done as an example of a medium sized project in verilog and to force me to have some form of documentation on my project. That's enough self publication to the question. Is the GPL (either version 2 or 3) applicable to work in HDL as it is not a traditional programming language but shares many of the same features? It certainly does not feel like I should use a CC license. I'm not sure this is the correct forum for this question but it seems most applicable.
i'm wondering which scripting language is better for distro related activity such as cron jobs , startup scripts and similar things.why is bash mostly used ? is it because of efficiency ?what about perl , python or php as potential successors to bash ?
View 14 Replies View RelatedSo a friend and I are new-ish to linux (I am reasonably comfortable with basic /etc text editing, command admin). We are, however, completely new to programming and (x)html. We have a few (what we think are) interesting ideas for dynamic websites.Ideally we would like to develop our own course of study to get to the point where we have a basic understanding of programming so that our adventures in the programming of a dynamic website would be possible. Much of what we need learn to do is the following: use daily updated public-domain data from several other sites, manipulate that data algorithmically, which would then yield updating output on our site. Here is what I would like to do:
1. learn the basics of programming with a language that would teach good code habits and fundamental understanding.
2. become comfortable with (x)html
3. learn another language for the extension of (x)html into a dynamic data-heavy website.
Question could you please suggest a way about going about 1>2>3?Ideally the language of (1) would be something that would not be "wasted" just on web design etc. As a language, C really appeals to me. However, if learning this wouldn't lend itself to being helpful in learning another language for webdesign maybe I shouldn't use it(?).If (1) weren't to be C, what language would be funadmental enough to teach good coding but also be helpful in learning (3)
other than Python, which languages are built into most Linux distros, using a real-time interpreter, like the Python prompt, where you can just enter some commands and test out ideas before actually creating a file with your program?
View 4 Replies View RelatedI've tried compiling C++ programs with extension .cc and .cpp. I've tried compiling with gcc, g++ and even cc (with .cc extension files). Earlier (as g++ wasn't installed) i tried installing g++ (sudo apt-get install g++) for which i got the message "g++ has no installation candidate". Later from Synaptic i found it as g++-2.95 and installed it. I've also installed pentium-builder
Whenever i've tried to install "build-essential" (using apt-get and aptitude) i've got messages along the line of "no installation candidate". I've searched many posts and not got the answer for this. I've treid update and upgrade before installation, no use. I have all the repositories checked in software sources and the server as "main server". Now, the main problem is: (when trying to compile a .cpp file)

i find the same when i tried to install wxpython from its source and hence cant complete it.

Is there an easier way (without using a package manager) to upgrade programs? For example, I just want to upgrade Amarok. In order to do this, I've had to upgrade every one of it's dependencies because they've all had minor upgrades from the versions I already have installed.
Is there an easier way to compile programs and their dependencies manually or are package managers the only way?
I'm relatively new to Linux and had a question regarding the GCC compiler.I realize that I can write an application and compile it using the GCC complier.I can even sell it (or not) . My question is do I have to make my source code public available also ?
