compile a compiler without a compiler?

lackluster · 12-30-2002, 07:37 PM

I need to re-install my version of gcc (I think that will solve the problem I had in http://www.linuxquestions.org/questi...threadid=39706).

But how is one supposed to compile gcc without a working copy of gcc? To be fair, I have the older version, but I cannot seem to get it working (it has the same problem). Help is greatly appreciated.

Yeah I've always wondered the very same thing...how do you install a compiler without a compiler? I thought (a long time ago, before i started LFS) that by going thru the steps of a LFS system would answer it for me...but i found out you have to use a base distro...bugger, that didn't answer it, heh.

You could use something like knoppix to do that. No it's not compiling a compiler without a compiler, but it would work without having to reveal the mystery of compiling the compiler.

Cool

Or you can let someone else compile it for you.

I found all the gcc I need in a tgz on ftp.slackware.com. It installed, but didn't help me any .... thanks anyways

btw, what is this knoppix you speak of MasterC?

which came first; the chicken or the egg?

make some friends... thats what the community is for - get one off someone as said by schatoor

Well I installed the package and it didn't help, I'm pretty sure the problem is not with my compiler, but with my libs. By the way, the rooster came first; the chicken was downright pissed.

Why not install a binary gcc, then compile gcc with your binary gcc, then remove your binary gcc, then use your compiled gcc (you with me?)

MasterC · 12-31-2002, 04:21 PM

Yeah, but isn't that pretty much what he did with installing the Slackware tgz?

Knoppix is one of those CD based distros. It runs without the need of an HD, and this is usually used by me as a rescue CD, or for demoing the power of linux to non-believers

Hmm, wasn't too clear on whether the tgz was binary or source. Shouldn't we troubleshoot (or at least find out) why binary gcc "didn't help me any"

Am I missing something?

Sorry ... what I meant to say is that I installed a BINARY tgz of gcc (I thought that was clear ... oh well) but I still get :

Code:

/usr/local/lib/libc.so.6: undefined reference to `_dl_lazy@GLIBC_2.1.1'
/usr/local/lib/libc.so.6: undefined reference to `_dl_dst_substitute@GLIBC_2.1.1 
'
/usr/local/lib/libc.so.6: undefined reference to `_dl_out_of_memory@GLIBC_2.2'
# and so forth #
collect2: ld returned 1 exit status

when I try to compile anything with gcc. Thus, I am led to believe the problem is not with gcc (I guessed that, but am scraping the bottom of the barrel here).

_dl_ prefix leads me to believe that /usr/local/lib/ld-linux.so.2 has something to do with it, but what?? Thanks for the replies.

-sorry, my fault

MasterC · 12-31-2002, 05:22 PM

I was just guessing, luck must be on my side today, how odd?

I think bulliver is right though, I am not too sure what is goin on? I glanced over the thread linked at the top, but still have no idea.

Since I know absolutely nothing above the basics, I turned to my trusty friend www.linuxfromscratch.org

Although I still have no idea, I at least can give suggestions...

Did you remove your old glibc? Is your new GCC symlinked properly, and also pointing to cc?

How did you compile glibc? With what options et al?

Cool

lackluster · 12-31-2002, 06:32 PM

I configured glibc2.3 using
--prefix=/usr/local/glib2 and --enable-add-ons

I did not remove the old glibc as the INSTALL file instructed me not to.

I don't know if gcc is linked properly where & what should the links be?

MasterC · 12-31-2002, 07:38 PM

Again, I am but an idiot when it comes to anything but how to start the X gui

But over at LFS:
http://www.linuxfromscratch.org/view...ter06/gcc.html

Looks like you need to link some libs as well?

I am just shooting in the dark, so if you've already done this, or it doesn't help, sorry.

Cool
