Hi I am having trouble getting past chapter 5.5 of Linux From Scratch 6.8 book in which we have to install GCC-4.5.2.
After make and install of GCC-4.5.2 when we have to execute this below command for linking :

ln -vs libgcc.a `$LFS_TGT-gcc -print-libgcc-file-name | \
sed 's/libgcc/&_eh/'`

i get an error :

bash: -gcc : command not found

What does this above error mean ..please help ?
Or atleast guide what exactly $LFS_TGT-gcc is doing maybe then i can figure it out ?
It does link libgcc.a despise the above error ...
Is this an issue to be ignored ?
BTW i am using VirtualBox to build the LFS n LFS LiveCD


Thank you

It means you haven't set the variable LFS_TGT or it somehow got unset. You were supposed to do that in chapter 4.4. It also means your binutils build is probably not correct either.

Hi,

This $LFS_TGT-gcc should expand to the value that $LFS_TGT holds and -gcc (example: i686-lfs-linux-gnu-gcc)

LFS_TGT is set in this chapter: 4.4. Setting Up the Environment

Hope this helps.

If you get that error you must have made a mistake earlier. Seems to me that the variable $LFS_TGT is not set.

I checked .bash_profile and .bashrc content using cat command ... and they are the same in both according to the book ...

.bash_profile ...content :

exec env -i HOME=$HOME TERM=$TERM PS1='\u:\w\$ ' /bin/bash

.bashrc ....content :

set +h
umask 022
LFS=/mnt/lfs
LC_ALL=POSIX
LFS_TGT=$(uname -m)-lfs-linux-gnu
PATH=/tools/bin:/bin:/usr/bin
export LFS LC_ALL LFS_TGT PATH

I hope that is correct unless i am supposed to replace the uname -m with i686 ??

And binutils compiled fine ..at least i think coz i checked the log file i didn't notice any errors even the tools section contains a folder called i686-lfs-linux-gnu

Even the gcc-4.5.2 compile and install went without any errors. Should i try recompiling them again ..for reinstall do we first remove the directory files ?

Btw thank you for the quick reply

Hi,
Did you check if the LFS_TGT variable is set?

No, you do not need to do that by hand. uname -m is a command that is executed and will do it for you.

If LFS_TGT was not set correctly then you need to start from scratch.

If you redo a package you always need to remove the source directory (as stated in the LFS book: 5.3. General Compilation Instructions - Last important block.......)

Is there a way to tell if it was set correctly ...because i went back checked .bash_profile and .bashrc both are correct according to the book . I know uname -m is a command i ran it just to make sure and the out i received was i686

So my only option is from scratch ?

I tried recreating the .bashrc and bash_profile and then ran the "source ~/.bash_profile" command and i get an error :

bash: exec: env: not found

Hi,
You don't know how to echo a variable? If that is the case then your level of experience is probably too little to build an LFS system (vi. Prerequisites).

Anyway: echo $LFS_TGT

If .bashrc was/is correct then you would not have had the error you originally posted. It shows that LFS_TGT was not set. Are you sure you are executing the commands as user lfs?

You're still very early in the process of building, I would start from scratch (but also keep in mind what the Prerequisites says.....).

Hope this helps.

Umm.. I did run them as user lfs and yes i do know how echo a file ... that is why i mentioned if i were to replace it with i686 ... well thanks i anyway i will consider your idea of starting over

Thank you

Hey druuna,

Question is .bashrc supposed to be created as root or user lfs ??

Hi,

As stated in the book (4.3. Adding the LFS User. Last step): User lfs

Hope this helps.

Thanks i think i figured what is wrong thanks for the help

You're welcome

Have fun with the build!

You're welcome
