Details on this package are located in Section 10.42.2, “Contents of Grep.”
The Grep package contains programs for searching through files.
When cross compiling, the configure script does not determine the correct values for the following. Set the values manually:
cat > config.cache << EOF ac_cv_func_malloc_0_nonnull=yes ac_cv_func_realloc_0_nonnull=yes EOF
Prepare Grep for compilation:
./configure --prefix=/tools \
--build=${CLFS_HOST} --host=${CLFS_TARGET} \
--disable-perl-regexp --without-included-regex \
--cache-file=config.cache
The meaning of the configure options:
--disable-perl-regexp
This ensures that the grep program does not get linked against a Perl Compatible Regular Expression (PCRE) library that may be present on the host but will not be available when building the final system.
--without-included-regex
When cross-compiling, Grep's configure assumes there is
no usable regex.h installed and
instead uses the one included with Grep. This switch forces
the use of the regex functions from EGLIBC.
Compile the package:
make
Install the package:
make install
