Linux bncsutil?

[K]

I had modified a version of bncsutil to build on linux a while ago, but the link I posted there no longer works.  I'll have to dig around on my desktop later to see if I still have the source.

Here it is: http://www.fileshost.com/en/file/35048/bncsutil-tar-gz.html

You'll need to install libgmp to build.

I can't really help you resolve it.  I would suggest installing a distribution that requires less fussing in order to get a working gnome/kde/whatever session.

I suggested Ubuntu, but he seems to think it's beneath him.

Is a gui necessary? I just thought i'd install xorg and gnome for kicks.

@K: Thanks! That's exactly what I needed!

Productivity increases substantially when utilizing an interface as opposed to working within the confines of a terminal.

Unless the interface slows down the system...

It'd be understandable in his case since he's trying to run Gnome.

I prefer a minimalist approach, and then start adding features from there.

[Barabajagal]

Ya... I always use the old Windows style interfaces...  Hate themes..

I installed vista on a VM... it took 2 and a half hours to install, and another half hour to get it to where I could use the OS because of the bloated GUI.

[brew]

@K or someone who knows:
Is this the reason why i needed libgmp?
It wasn't in the package repository, so i just used make. it compiled fine (into libbncsutil.so) and i compiled my program with gcc blah.c -shared libbncsutil.so -o blah. When i try to run it, i get the error "Segmentation Fault". I'm no gcc expert-- anyone have an idea of what i would have to do?

[iago]

Compile it with -g, then run it in gdb:

gdb <programname>
run <parameters>

When it crashes, run "backtrace"

Should tell you what's going on.

If you don't have libgmp installed, it wont compile -- you'll get all sorts of errors about mpz_* not being declared, mpz_t does not name a type, etc.

The problem is that you're linking it wrong.  Try:

gcc whatever.c -lbncsutil -o whatever


The -shared argument is used to create a shared library, not link with one.

ah, gotcha.

I tried installing libgmp with pacman, but i dont think that actually did anything.
so i downloaded the source and i'm having trouble compiling it-- no scratch that, running the ./configure script.

configure:3865: gcc -O2 -fomit-frame-pointer  conftest.c >&5
collect2: cannot find 'ld'

This is the problem.  It's looking for the linker 'ld' yet you have no 'ld'.  I'm pretty sure you should have an 'ld' if you have a 'gcc'.  Honestly, install a different distribution.  These are some weird issues you're running into, and it would be much easier to get a friendlier distro than troubleshoot this stuff.

[brew]

arrg! in that case, how would i get ld? it's not in the packages...

[Kp]

You didn't install the assembler/linker.  You need to install the binary utilities if you expect to link anything.

Also, it looks like you logged in as root.  Don't do that.

[brew]

Heh. All i needed to do is reinstall binutils, and look at that. i have ld. so i did ./configure, got a bit farther than i did last time, but it errors again. i was missing m4. Fortunately it was easier to find and install then i expected.. so after 10-12 minutes of verbose output, compiling and linking it finally compiled. Wow! So now with libgmp compiled, i went back to compile bncsutil. It came out just fine. I then mv'd it to /usr/bin/ld. Then... when i go back to compile my project (gcc blah.c -lbncsutil -o blah) it gives me the error "collect2: ld terminated with signal 11 [Segmentation fault]". Googling was no help at all, I couldn't find what i was looking for. Help? I'm somewhat lost. All that hard work got me was having ld segfault on linking instead of segfaulting on runtime.

EDIT ** When i tried to do ld -version it gave me a segfault. it's the damn linker itself. WHY?
iago was right. gdb tiem nao ^^;;

Oh wow, I pacman -Sy binutils again and it all of a sudden works...? when I get this problem it appears as if the only solution is to reinstall it. Why does it have to be so screwy?
Not only that, but i still get an error. It can't find -lbncsutil, what now?
