GCC cant create executables

trem0rs · 04-13-2017, 01:43 PM

Hi, I have some years now using slackware, back in 2014 I used gcc without having any problems but now I am starting to have them.

If I try to create a simple hello-world program I get this error msg:

Code:

hll.c:1:19: fatal error: stdio.h: No such file or directory
 #include <stdio.h>
                   ^
compilation terminated.

And when I try to intall anything sbo I get:

Code:

checking for C compiler default output file name... configure: error: C compiler cannot create executables
See `config.log' for more details.

When I open the config.log this is what I get:

Code:

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by configure, which was
generated by GNU Autoconf 2.59.  Invocation command line was

  $ ./configure --prefix=/usr --libdir=/usr/lib --sysconfdir=/etc --localstatedir=/var --enable-plugins --enable-gtk --build=i486-slackware-linux

Code:

userx@slackwhere⚡~ $gcc -v

did you run that on the command line to make sure you even have gcc installed?

if you did anything other than a full install of Slack you may have inadvertently had it NOT install gcc.

bassmadrigal · 04-13-2017, 01:56 PM

Looks like you either have a partial installation or a broken installation. Let's try and get some more information...

What Slackware version are you running (based on your kernel, I'm thinking 14.1 and your ARCH seems to indicate you installed the 32bit version)? Did you do a full or partial installation? If it was partial, do you remember what you left out?

stdio.h that is referenced in those files is likely the one contained in the glibc package.

The ./configure script already ran gcc, so it is installed...

This can also happen if you have a multilib setup and you've someone messed it up, IIRC.

But from your log:

Code:

configure:2842: gcc -O2 -march=i486 -mtune=i686   conftest.c  >&5
/usr/lib/gcc/i486-slackware-linux/4.8.2/../../../../i486-slackware-linux/bin/ld: cannot find crt1.o: No such file or directory

/usr/lib/gcc/i486-slackware-linux/4.8.2/../../../../i486-slackware-linux/bin/ld: cannot find crtn.o: No such file or directory

I'm going to go with the others in diagnosing it as an incomplete installation.

trem0rs · 04-13-2017, 05:14 PM

I have this slackware installation since 2013 and as I said in the first post I used gcc many times with no problem, I don't think it is a partial-install cause when I installed it I had php, python and perl and except for some games and desktop environments I installed nearly everything.

But here is what I get when I type; gcc -v

Thanks for the answer,

Is this a 32-bit Slackware installation?

Does stdio.h actually exist somewhere in /usr/include? I'll check the exact path later tonight for you.

Is it at all possible that CFLAGS and/or might have been set incorrectly somehow? (check that)

Can you give us a better answer than "now" as to when your issues started?

Have you tried rebooting? (sorry to have to mention this)

volkerdi · 04-13-2017, 05:29 PM

It seems that you are running Slackware 14.1, 32-bit.

Try fetching the glibc packages from slackware-14.1/patches/packages/ and installing/reinstalling them with this:

upgradepkg --reinstall --install-new glibc*.txz

Thanks a lot man!!

The problem seems to be I didn't have glibc installed:

Code:

:~# upgradepkg --reinstall --install-new glibc*.txz
Cannot install glibc*.txz:  file not found

So I got to run;
slackpkg install glibc

I installed it and now I can finally compile!

Thank you,
trem0rs

dugan · 04-13-2017, 06:39 PM

I'm kinda curious as to how your installation lost its glibc package. :P

Just so you know, the "file not found" error doesn't that glibc wasn't installed. It just means that the glibc*.txz packages you downloaded weren't in the working directory where you ran that command. However, the fact `slackpkg install glibc` worked does mean it wasn't installed.

rob.rice · 04-14-2017, 02:38 PM

did you convert this into an elf file by running link on it ?
the kernel in slack doesn't run a out binary files
so every thing coming out of gcc needs to be linked even the hello world program

dugan · 04-14-2017, 05:19 PM

I don't know what you're talking about.

Code:

bash-4.4$ vim helloworld.c
bash-4.4$ gcc helloworld.c 
bash-4.4$ ./a.out 
Hello world

That's with a stock -current kernel. I've always been able to run a.out files in previous versions too.

rob.rice · 04-16-2017, 06:20 PM

in the linux kernel configuration under executable binary formats aout is not enabled
so you have 2 options
1 link the a.out file
2 have the kernel link it at run time by enabling the aout executable binary format as a builtin in the kernel configuration then rebuilding the kernel and installing it

https://en.wikipedia.org/wiki/Execut...inkable_Format
https://en.wikipedia.org/wiki/A.out

I asways go with option 2

dugan · 04-16-2017, 06:49 PM

Hmm... interesting.

You are correct that support for a.out binaries are not enabled in Slackware's kernel. I checked.

Running "gcc" with no flags seems to be all that's needed to create linked, runnable ELF file. I checked that too:

Code:

➜  helloworld file a.out 
a.out: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, not stripped, with debug_info

That's the "a.out" file created in my last post.

rob.rice · 04-17-2017, 03:20 AM

try this "gcc -o hello hello.c"
