... so many errors here ...

I don't know how to override headers PATH to /llvmtools/include, when I try to configure with CFLAGS="-I/llvmtools/include" CXXFLAGS="-I/llvmtools/include" ./bootstrap still fails to build.

Strange. I had no issues with CMake for llvmtools... I even forgot to install it, so I had to open another tmux session, build and install it to llvmtools

[dslm4515]

A quick fix would be to build Cmake under chroot.

I may try another build on a Gentoo host :P

I know, but building libuv need autoconf, automake, and libtool.

I know, but building libuv need autoconf, automake, and libtool.

llvmtools should have libuv to build cmake for llvmtools

[owl4ce]

I mean in chroot

In chroot, llvmtools should have libuv. Just change the prefix to /llvmtools ... although, I'm not sure if the bootstrap script will need autotools (autoconf, automake, etc)

Does CMake bootstrap if you try to build CMake for your host?
./bootstrap --prefix=/usr

Yes, cmake bootstrap successful in host but not when building it.

Ok, I'll try cmake in chroot with libuv in llvmtools later. Currently very tired.

Ah I see, this was my mistake that including zlib header (preferred to use because installed (needed by pigz)) in llvmtools. Should be normal if not using systems installed programs.
