I want to learn more about compilation processes, get to know UNIX-like systems more, and whatever. That's ok too. You are bound for a very fun ride, even if it takes years to realize that it never ends, though :) So I've downloaded the source for gcc, and the README says that I need the ISO C90 compiler. There is no ISO C90 compiler. There is an ANSI/ISO standard for the C Programming Language, which is _implemented_ by some compilers. You already have an installation of the GNU C compiler (GCC), installed as the system compiler of your FreeBSD system. This installation of GCC includes support for some of the standards related to the C Programming Language. You can find out more about the standards supported by your installation of GCC, by running: % info gcc In the info browser that pops up, follow the Standards: link and you can read a lot of details about the various language standards supported by your GCC installation. Where do I get that? You have it already. See the info documentation of GCC. In short, you can get GCC to run in a special mode, which is almost conforming to the ISO9899:1990 standard for the C language. This mode is enabled by the options: % gcc -ansi -pedantic ... or by the equivalent set of options: % gcc -std=c89 -pedantic ... In this mode, GCC will produce diagnostic messages for all non-ISO programs, with only one notable exception, documented in its manual (see the section `Options Controlling C Dialect'): The alternate keywords `__asm__', `__extension__', `__inline__' and `__typeof__' continue to work despite `-ansi'. You would not want to use them in an ISO C program, of course, but it is useful to put them in header files that might be included in compilations done with `-ansi'. Alternate predefined macros such as `__unix__' and `__vax__' are also available, with or without `-ansi'. This minor exception means that GCC, even with the options mentioned above is *NOT* 100%-conforming to the C90 standard, but it is so close to a fully-conforming implementation of a C90 compiler, that you will hardly ever notice, unless you use one of the extensions listed above. OK it looks like I can compile gcc 4.1 with an older gcc, but that's not my choice. I don't know why you feel that this is not a good choice, but if you go through the info documentation of GCC and *still* feel this way, then I'd be interested to know why :) [ But if that's the case, how was the first gcc compiled? xD ] [ How was the first ever compiler compiled? xD ] This process is called compiler bootstrapping. Google for it, and you will be amazed at how it works :-) Regards, Giorgos ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

There is no such thing as *the* ISO C90 compiler, but, the gcc README almost certainly says that you need *a* ISO C90 compiler, i.e. a compiler that can compile programs written in the C language as defined by the 1990 ISO standard. Gcc is one such compiler. [ But if that's the case, how was the first gcc compiled? xD ] With whatever C compiler the gcc developer had at that time. [ How was the first ever compiler compiled? xD ] It probably wasn't. The first ever compiler was most likely written in assembler. Later on the first compiler for a new language has usually been written in some other language. -- Insert your favourite quote here.

The evolution of programming. Can someone give me a link? I may be one of the missing links chuckles I remember writing programs during the late 50's in binary on a form with four columns. Column 1 was to describe the purpose of the step. Column 2 contained the binary code for the step. Column 3 used my own shorthand to illustrate the meaning of the binary code in human language and column 4 described what happened to the contents of the registers. ___ In the early sixties I wrote a small program that translated data rather like the contents of column 3 into contents equivalent to column 2. meant I did not have to remember the binary numbers but only use a consistent set of abreviations. Saved me a hell of a lot of time I can tell you!!! I still had to write the descriptions.. and get the whole lot punched into 80 column cards begore it was of any practical use.
