Locating zlib in a cross-build

Locating zlib in a cross-build

[Chris Wilkinson]

I successfully built the powerpc-e300c3-linux-gnu toolchain on a
Debian/AMD64 host.

I used the toolchain to cross-compile a source package that wants zlib.

CC=xx, --target=xx, --host=xx were specified in the ./configure command line.

Configure complains that zlib is missing. It appears to be built as
part of the toolchain. I see the libraries under the .build/.... dir.

I suppose I need to tell configure where it is. How I should do that?

Thanks
Chris Wilkinson

No. You have to build your own:
 - crosstool-NG does not build a zlib that is installed in the toolchain.
 - gcc does build a version for itself, so it is not available.

Crosstool-NG does not provide a BSP. Crosstool-NG only provides a toolchain:
 - C library, headers and libraries: glibc, eglibc, uClibc... Your pick.
 - compiler: gcc
 - binary utilities (assembler, linker...): binutils

That's all. If other tools are built, that's only for internal use, and it
is not installed with the toolchain.
