I'm building lfs-7.5.

When I run `make mrproper` in chapter **6.7**, it says:

> make: gcc: command not found

and on running `bash /tools/bin/gcc`, it says: 

> bash: /tools/bin/gcc: no such file or directory

This is the same problem as [here][1]. Even the information given by the person who asked the question in the comments is same as mine.

He says that he did "**third pass**" of `gcc` in **chapter 5**. If this was the case then the author of LFS would have clearly indicated to us to perform 3 passes. I'm guessing that I'm making a subtle mistake somewhere, but I can't seem to find out where.

According to the support provided by LFS authors, they ask us to redo the whole thing from the beginning. I agree with them, but without knowing where the mistake might have happened we are bound to make the same mistake again (as I did). The output provided by the person who asked the question in the LFS support question matches mine. This is the [link][2].

Another question about the same topic [here][3] did not yield any answers.

Please help.

BTW, when I found out that `gcc` was not linked to the libraries in `/tools/lib` of LFS, I manually created a simlink from `libc.so.6` to `/lib` and `/lib64` under `/mnt/lfs` where I mounted the LFS partition. But when I was executing `make headers_check` in **6.7** (after `make mrproper`), it complained that it didn't find `libz.so` and when I searched in `/tools/lib`, I couldn't find it.
