export LD_LIBRARY_PATH=/usr/local/lib worked for me.

Hi there!
I have this on config.log file

configure:3906: g++ -c conftest.cc >&5
g++: error trying to exec '/usr/libexec/gcc/i486-slackware-linux/4.1.2/cc1plus': execv: Exec format error
configure:3912: $? = 1
configure: failed program was:

i am following the instructions on
http://www.nongnu.org/avr-libc/user-...nstall_avr_gcc
Any help will be very appreciated

Thanks

@orcaja, I recommend you start your own thread rather than reviving a 3-year old thread (again) that has nothing to do with your problem.

Hi,
I am trying to cross compile GCC tool chain for powerpc. I am getting following error. I checked the config.log, not getting clue for the problem. I have searched previous messages with respect to glib configuration errors, but could not figure out the root cause.

Hello Friends,

I am new here and this is my first mail. If i am breaking any rules, kindly forgive me.

I am trying to build "buildroot" package on my PC for ARM Based board. It first tries to build cross-compiler toolchain for ARM. while configuring gcc, it gives following error:
checking for suffix of object files... configure: error: cannot compute

suffix of object files: cannot compile
See `config.log' for more details.
make[1]: *** [configure-target-libgcc] Error 1

when i see config.log file, i found following:

configure:3325: checking for suffix of object files
configure:3346: /usr/bin/gcc -c conftest.c >&5
configure:3349: $? = 0
configure:3371: result: o

which, i think, suggests that it is computing what should be the suffix of the object files.

I went through your conversation, and i tried

]#gcc -v

and the output was

Using built-in specs.

Thread model: posix
gcc version 4.2.1 (SUSE Linux)

and gcc is at /usr/bin,
i created the link in /bin too by using

]#ln -s /usr/bin/gcc /bin/gcc

as yoyo suggested in previous postings.

also i tried
]#export LD_LIBRARY_PATH=/usr/local/lib

but no gain.
does anyone has any clue about this problem's solution?

help is always appriciated friends.

regards,
Prashant Sangal

Could this be caused by forgetting to remove the files in the build-gcc directory after pass 1?
I believe pass 2 requires a configure and make in an empty directory.

I enccounter the exact problem like #5. who can tell me why ?
A host root can run gcc while a "new root" can not do it.

hi, i have also same problem i am posting gcc -v output.

i am building gcc pass 2 from LFS 6.6 ebook. please tell me how to solve this error?

Since the new glibc has dependency on mpc, gmp and mpfr hence you have to show that in your LD_LIBRARY_PATH. By making these changes I was able to move ahead.

LD_LIBRARY_PATH=$PREFIX/mpc/lib:$PREFIX/mpfr/lib:$PREFIX/gmp/lib:$LD_LIBRARY_PATH
