Question

%build
# Build all apps
{
for app in * ; do
    pushd $app
    sed -i '/XAW_/ s/)/, xaw7)/; /XAW_/ s/XAW_CHECK_XPRINT_SUPPORT/PKG_CHECK_MODULES/' configure.ac
    autoreconf -v --install
    %configure --disable-xprint
    make
    popd
done
}

can anyone tell me what operations will sed command do on configure.ac and autoreconf

Answer 1

The sed-command will look for lines matching XAW_ and – when found – replace ) with , xaw7), and XAW_CHECK_XPRINT_SUPPORT with PKG_CHECK_MODULES.

[EDIT] autoreconf will look for any missing “auxiliary files” and install them. See the documentation for details.
