    a universal compiler....!!!

    I am just speculating my imagination that whether at all, is it possible to build a universal compiler....??

    For example, if i am programming in c( I use turbo c++ 4.5), is it possible to embed java code and some other language so that when the program gets executed....the java code gets executed simultaneously as the remaining c code...!!

    Or, if i figure it in this way...If we have one environment in which compilers of java, c, perl, pyhton are linked together...and when a program is written containing multiple codes of different gets executed accordingly.....!!!

    Sorry for my ignorance, i am a newbie...and quite new to programming....!!!

    looking for a reply,

    Is it possible? Absolutely. Would it be trivial to design such a system? Hardly. The complexity of such a project would be incredible, and probably require the skills of many talented developers to come up with a good solution to the problem.

    You can embed perl in C, and C in perl, altho I've never tried to do either one. Apparently all that's involved in the former case is linking in the perl library, which is of course written in C:

    perlembed - how to embed perl in your C program

    And then you can call functions to call perl subroutines from another file. So that is on this road.

    I will get around to trying it at some point; depending on what you are doing it might even be incredibly efficient, is my hunch, since the "overhead" of the perl interpreter would be sorted out at compile time, and perl itself would not be required at runtime.

    C programming resources:
    GNU C Function and Macro Index -- glibc reference manual
    The C Book -- nice online learner guide
    Current ISO draft standard
    CCAN -- new CPAN like open source library repository
    3 (different) GNU debugger tutorials: #1 -- #2 -- #3
    cpwiki -- our wiki on sourceforge

    Microsoft's programming tools, the ".net" buzzwords are claiming to do just that. Several language - compiled modules to link together. I find the task too daunting... several books and online references just left me with gigantic headaches.

    I don't know why one can't enclose source code units with standardized keywords to identify the languages... and let a conglomerate compiler deal with it.

    Insofar as existing compilers produce OBJect files as output, and given that it is possible to link those object files and the functions in those object files follow standard (cdecl or stdcal) calling conventions, yes it is currently possible to do so, but not mixed code within the same source file.

    So the only real issue is getting the compiler to recognize what code it is compiling, the most suitable method of course is to use the filename extension

    Another issue would probably be that it wouldn't work with Turbo C! The compiler is old and outdated. Get a newer one: Integrated Development Environment - cpwiki

    You also need to remember the difference in platforms here. Java gets compiled into bytecodes, C gets converted into machine code. A processor runs the compiled C, natively, bytecodes have to be interpreted by a virtual machine. So it's possible to combine different platforms, but it's not trivial (except for some languages, perhaps). It also doesn't always make sense to do. Combining C and Java? Kinda defeats the purposes of each language.

    Here's an example of two languages that do make sense to integrate:
