How do I use a sysroot with autoconf?

Question

I am trying to cross-compile fontconfig for a ARM device. I've got a sysroot with all the dependencies etc. Fontconfig uses autoconfig so I did this:

./autogen.sh --host="arm-arm1176jzs-linux-gnueabi"         \
              --sysconfdir="${SYSROOT}etc"    \
              --prefix="${PREFIX}"        \
              --localstatedir="${SYSROOT}var" \
              --disable-docs 

However, there is no flag like --sysroot so how do I pass my sysroot to autoconfig ?

Answer 1

I guess you set $CC to your cross-compiler's path. You can easily add some flags:

export CC=gcc --sysroot=/path/to/sysroot

Note that this works with all tools so keep it in mind ;)
