-- 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: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.
