-- Perl configuration --
Perl uses a huge configuration file, normally generated via the Configure script
at build-time. This fails when cross-compiling though, so we need to supply our
own.
We're using perlconfig.pl to piece together the final configuration from a bunch
of configuration files(all ending in .config). Please refer to perlconfig.pl's
POD for information on usage and syntax.
Throughout the files, you will see a bunch of references to private symbols with
the prefix "owrt". These are used to control output in an effort to both
simplify writing configuration files, as well as to provide switchable options
to select the feature set of the resulting perl installation.
The following will be a summary/quick reference of all private symbols we're
currently using:
Passed via architecture configuration file(mipsel.config, i486.config, ...)
---------------------------------------------------------------------------
Symbol Values Description
owrt:bits 32/64 Target's native word length.
owrt:endian little/big Target's endianness.
owrt:arch mipsel, i486, ... Target's architecture name.
owrt:sig_count 64/128 Number of signals the target
provides(NSIG - 1).
owrt:sigs * Symbolic names of the first 32 signals
this architecture provides, in numeric
order. Separated by whitespaces.
owrt:sig_name_extra * Symbolic names of any additional signals
this architecture provides after
owrt:sig_count. Separated by
whitespaces.
owrt:sig_num_extra * Numeric values associated with the
signal names provided in
owrt:sig_name_extra. Separated by
whitespaces.
Passed via command line
-----------------------
Symbol Values Description
owrt:libc glibc/uclibc/musl Which C library implementation is in
use.
owrt:threads yes/no Whether to enable threading support.
owrt:ipv6 define/undef Whether to enable IPv6 support.
owrt:target_cross * Target architecture's host triplet.
owrt:target_cc * C compiler to use.
owrt:gccversion * target_cc's version number.
owrt:cflags * Additional C compiler flags.
owrt:ldflags * Additional linker flags.
owrt:staging_dir * Same as OpenWRT buildroot's
$(STAGING_DIR).
owrt:host_perl_prefix * host-perl installation prefix.
Passed via version.config
-------------------------
Symbol Values Description
owrt:perllibpath * Path to perl library files, from the
target's point of view.
