gcc doesn't seem to be working...

lukeiamyourfather · 07-18-2007, 04:22 PM

okay, I am trying to build an LFS-6.2 system and have run into many bumps on the road, but this one is the hardest.

also, the host is an Ubuntu Dapper (6.06), i586 AMD-K62 500 MHz, 384 MBs RAM

I am in chapter 6, in the re-ajusting the toolchain (6.10) section. I get to the part where you make sure the compiler is working, and I do this:

echo 'main(){}' > dummy.c
cc dummy.c -Wl,--verbose &> dummy.log
readelf -l a.out | grep ': /lib'

then I get an error that there is no a.out file. it seems that gcc is not generating the executable.

this was a test to make sure that the compiler was working properly. well, apparently it failed.

then, I tried the next test:

grep -o '/usr/lib.*/crt[1in].* .*' dummy.log

the book tells me that this is the correct results:

/usr/lib/crt1.o succeeded
/usr/lib/crti.o succeeded
/usr/lib/crtn.o succeeded

I only got the first two. "/usr/lib/crtn.o" did not even show up.

thanks for any help you can provide.

EDIT: i got some more info:

i tried this:

cc dummy.c

and got this:

/tools/lib/gcc/i586-pc-linux-gnu/4.0.3/../../../../i586-pc-linux-gnu/bin/ld: cannot find -lgcc_s
collect2: ld returned 1 exit status

it looks like it can't find a library file.

what do i need to do?

You should find the named library (libgcc_s), and then make sure the compiler can also find it. You can do this either by adding an appropriate -L switch to the compiler commandline, or by moving or linking the library to a default library location that will be searched by the compiler/linker.

okay, i think i know what you meant. i have little experience working with libraries and stuff, so what commands/actions would i use?

thanks,
chris

To find the library:

Code:

find / -name "*libgcc_s*"

To use the library:

Code:

gcc -L /directory/where/libgcc_s/was/found .....rest of gcc commandline.....

Just try to think like a compiler.

well, i am starting again. i had to delete that partition.

anyway, when i get paid from my job, (video editing and server administration [yes, i am fourteen]) i am going to buy myself a new motherboard and processor and RAM, plus my boss is giving me a bigger hard drive.

so good bye to 4 hour compilations on my amd k6 @ 474 MHz 384 MBs RAM!!!!

thank god i have a job...

hehe, that's nothing, I had to start over 2 times and now I'm stuck again at the less-394 package... lfs requires lot of patience I guess!
