Description Daniele Salvatore Albano 2009-08-01 17:28:41 UTC 
Hi,

i was trying to compile pciutiles having zlib but it fails because can't find lz!

Probably a path mismatch, but i've done some tests without success. Zlib are there and works correctly, openssl compiles successfully!

Here there is the output
make[2]: Leaving directory `/home/daniele/Development/OPBXA/buildroot-git/build_i686/pciutils-3.0.1/lib'

broken toolchain and/or toolchain setup.
What does
$ grep TOOLCHAIN .config
say?

nm, you attached it, sorry.
BR2_TOOLCHAIN_EXTERNAL=y

Just use the internal toolchain.
Comment 4 Thomas Petazzoni 2009-08-01 22:00:09 UTC 
Why do you say « Just use internal toolchain » ? External toolchains are now supposed to be supported. It's not because you don't personaly care about external toolchain support that other don't. And I do care, for example.

Daniele, thanks for the report, I'll have a look at it.
