[SOLVED] Problem compiling zlib

Lennie · 06-06-2016, 09:05 AM

I'm trying to compile zlib and get this error. I wonder both about why it says it doesn't have shared library support and that it can't find ld. And also about the security issue about vsnprintf().

Code:

Checking for x86_64-unknown-linux-gnu-gcc...

When it barfs, try running

Code:

which ld

It's not finding your linker, needed for every compile. If you're in chapter 5, it will be the ld from the base system. in ch 6, it should be in $LFS somewhere.

There is no ld... Something must have gone wrong with binutils. I found in my log from adjusting the toolchain:

Code:

'/tools/bin/ld' -> '/tools/bin/ld-old'
mv: cannot stat '/tools/x86_64-unknown-linux-gnu/bin/ld': No such file or directory

I'll check my scripts and start over. Thank you for guiding me in the right direction.
