"c Compiler Cannot Create Executable"

[g33k]

When cross-compiling (actually, when running the configure script), I sometimes get an error that says "C Compiler Cannot Create Executable". Does anyone else get this? What does it mean? How do I fix it?

Thanks!

I get this from certain configure scripts as well. Here's a slice of config.log:

Code: [Select]

configure:588: checking host system type
configure:613: checking for gcc
configure:726: checking whether the C compiler (armv5tel-linux-gcc -O2 -Wall -Wl

mv5tel-cacko-linux/3.3.2/collect2)
configure: failed program was:

#line 737 "configure"
#include "confdefs.h"

main(){return(0);}
Is this an issue with  my environment possibly?  I get this error both with the native and zgcc images on the z, and with the SDK on a  Debian sarge box.

Thank you

Sounds like either your toolchain should be compiled with other standard include directories or you should supply some more CFLAGS pointing to where your proper libc.so is.

sh-2.05a# strings `which armv5tel-linux-gcc` |grep GLIBC
GLIBC_2.1
GLIBC_2.0

What weirds me out here is that gcc and collect2 seem to be linked against different glibc versions.

sh-2.05a# strings /opt/arm/3.3.2-vfp/lib/gcc-lib/armv5tel-cacko-linux/3.3.2/collect2 |grep GLIBC
GLIBC_2.3
GLIBC_2.1
GLIBC_2.0

I have  glibc 2.2.5 on the debian system in question. On my slackware boxes I have 2.2.4 and 2.1.3. I guess technically I could upgrade, but I have to think that I've done something horribly wrong as I would expect different results with the zgcc.img. I'm fairly sure that others are using it with no problems.

What madness have I perpetrated?
