[Clfs-dev] Zlib dev during Chapter 5 cross tools

[William Harrington]

Since moving to gcc 4.8.x I noticed something interesting.

I normally use LFS or CLFS builds to build current LFS or CLFS  
versions, but sometimes I use debian.

I did notice today that the host system needs zlib headers available.  
I have built LFS and CLFS a lot with debian and I think this is  
something new.

We need to either build zlib during cross tools or in the host system  
requirements make sure that the host has the zlib dev files. Otherwise  
lto will fail during gcc build.

Adding zlib to cross tools is no issue, but is it needed? We cannot  
rely on users making sure their host has their distro's zlib dev  
package installed.

Any comments on how to go about this?

SIncerely,

William Harrington
