- -- 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.
