C compiler cannot create executables

C compiler cannot create executables

[Peter]

Hi,
 trying to configure a program I get the following message and .configure 
stops.

checking for C compiler default output... configure: error: C compiler cannot 
create executables

What has to be done to correct this?

Thanks & regards

Do this:

% echo "int main(void) { return 1; }" > foo.c && gcc foo.c -o foo ; ./foo

If you get any errors check for your gcc installation.

At a guess, you are missing the binutils package.

C compiler cannot create executables

[Claudiu mdc]

hi, I am trying to build bootstrap-image and I have this error when building libtool-cross:
| checking for i686-linux-gcc... i686-linux-gcc-4.3.1 -mcpu=pentiumpro
| checking for C compiler default output file name...
| configure: error: C compiler cannot create executables
| See `config.log' for more details.

I've built a custom toolchain which is in $PATH.
~/oe$ i686-linux<TAB><TAB> gives this output:
i686-linux-addr2line        i686-linux-gccbug                 i686-linux-ranlib
i686-linux-ar                   i686-linux-gcov                     i686-linux-readelf
i686-linux-as                   i686-linux-gprof                    i686-linux-real-ld
i686-linux-c++filt             i686-linux-i686-linux-gcc       i686-linux-size
i686-linux-cpp                 i686-linux-ld                          i686-linux-strings
i686-linux-g++                i686-linux-nm                        i686-linux-strip
i686-linux-gcc                 i686-linux-objcopy
i686-linux-gcc-4.3.1        i686-linux-objdump

I've also tested the toolchain with hello.c program:
# ----------------------
#include<stdio.h>

int main(void)
{
    printf("Hello World!\n");
    return 0;
}
# ----------------------
~/tmpHello$ i686-linux-gcc-4.3.1 hello.c -o hello
and it works.

so, I don't understand why compile task fails with this error.



Some bits abountmy configuration:
I use org.openembedded.stable branch

Some lines from my local.conf:
MACHINE = "i686-generic"
TARGET_OS = "linux"
DISTRO = "unmaintained/generic"

ASSUME_PROVIDED += "virtual/${TARGET_PREFIX}gcc"
ASSUME_PROVIDED += "virtual/${TARGET_PREFIX}g++"

PREFERRED_PROVIDERS = "virtual/qte:qte virtual/libqpe:libqpe-opie"
PREFERRED_PROVIDERS += " virtual/libsdl:libsdl-x11"
PREFERRED_PROVIDERS += " virtual/${TARGET_PREFIX}gcc-initial:gcc-cross-initial"
PREFERRED_PROVIDERS += " virtual/${TARGET_PREFIX}gcc:gcc-cross"
PREFERRED_PROVIDERS += " virtual/${TARGET_PREFIX}g++:gcc-cross"

Someone can help me?

First: what does config.log say? (it's somewhere in 
work/i686*/libtool-cross/*)

Secondly, you can't build for x86 using the generic distro because of 
namespace clashes. Try using angstrom-2007.1.

Thank you Koen for the answer. I followed your istructions,


I tryed to use "angstrom-2007.1" DISTRO as you told me, but there are
2 different behaviours depending of kind of building:
 	
>>> if I build a SINGLE PACKAGE (-b option)	
	for example: 
        ~/oe$ bitbake -b myPackages/myhelloworld/myhelloworld_0.1.bb -DD
	
	variables are exported CORRECTLY (with i686-linux- prefix)
        some examples:
		+ export LD=i686-linux-ld
		+ LD=i686-linux-ld

		+ export 'CC=i686-linux-gcc-4.3.1 -mcpu=pentiumpro'
		+ CC='i686-linux-gcc-4.3.1 -mcpu=pentiumpro'

		+ export STRIP=i686-linux-strip
		+ STRIP=i686-linux-strip

		+ export RANLIB=i686-linux-ranlib
		+ RANLIB=i686-linux-ranlib
		
	these i686-linux-* are in ~/oe/myToolchain/cross/bin directory 
        which is in my $PATH

	but the build fails with: | i686-linux-gcc-4.3.1: Success
| + cd
/home/claudiu/oe/oetmp/work/i686-angstrom-linux/myhelloworld-0.1-r0/
myhelloworld-0.1
| + do_compile
| + i686-linux-gcc-4.3.1 -mcpu=pentiumpro
-isystem/home/claudiu/oe/oetmp/staging/i686-angstrom-linux/include,
-I/home/claudiu/oe/myToolchain/cross/include -fexpensive-optimizations

-Wl,-rpath-link,/home/claudiu/oe/oetmp/staging/i686-angstrom-linux/lib -Wl,-O1
/home/claudiu/oe/oetmp/work/i686-angstrom-linux/myhelloworld-0.1-r0/
myhelloworld.c -o myhelloworld
| i686-linux-gcc-4.3.1: Success
NOTE: Task failed:

log.do_compile.18268
NOTE: package myhelloworld-0.1-r0: task do_compile: failed



>>> if I build bootstrap-image or other package in the metadata
WITHOUT -b option

	for example: ~/oe$ bitbake bootstrap-image -DD

	variables are exported WRONGLY (WITHOUT i686-linux-
        prefix, even if in local.conf I specified the prefix, see the first
        post), because I want to use my toolchain. Some examples:		
                + export LD=ld
		+ LD=ld

		+ export CC=gcc
		+ CC=gcc

 		+ export RANLIB=ranlib
		+ RANLIB=ranlib

		+ export CXX=g++
		+ CXX=g++

	the build fails on "shasum-native" with: | collect2: cannot find 'ld'
| + export BUILD_STRIP=strip
| + BUILD_STRIP=strip
| + cd /home/claudiu/oe/oetmp/work/i686-linux/shasum-native-1.0-r1
| + do_compile
| + gcc -isystem/home/claudiu/oe/oetmp/staging/i686-linux/include -Os
-isystem/home/claudiu/oe/oetmp/staging/i686-linux/include -o oe_sha256sum
main.c sha256.c
| collect2: cannot find 'ld'
NOTE: Task failed:
/home/claudiu/oe/oetmp/work/i686-linux/shasum-native-1.0-r1/temp/
log.do_compile.18246
NOTE: package shasum-native-1.0-r1: task do_compile: failed





Otherwise, if I still use "generic" DISTRO, I have the error specified in
the first post.
The config.log (placed in :
oe/oetmp/work/i686-linux/libtool-cross-1.5.10-r9/temp/log.do_configure.5538)
says the same things as above in the first post. It ends with these lines:
