README.config (3258B)
1 -- Perl configuration -- 2 3 Perl uses a huge configuration file, normally generated via the Configure script 4 at build-time. This fails when cross-compiling though, so we need to supply our 5 own. 6 7 We're using perlconfig.pl to piece together the final configuration from a bunch 8 of configuration files(all ending in .config). Please refer to perlconfig.pl's 9 POD for information on usage and syntax. 10 11 Throughout the files, you will see a bunch of references to private symbols with 12 the prefix "owrt". These are used to control output in an effort to both 13 simplify writing configuration files, as well as to provide switchable options 14 to select the feature set of the resulting perl installation. 15 16 The following will be a summary/quick reference of all private symbols we're 17 currently using: 18 19 Passed via architecture configuration file(mipsel.config, i486.config, ...) 20 --------------------------------------------------------------------------- 21 Symbol Values Description 22 owrt:bits 32/64 Target's native word length. 23 owrt:endian little/big Target's endianness. 24 owrt:arch mipsel, i486, ... Target's architecture name. 25 owrt:sig_count 64/128 Number of signals the target 26 provides(NSIG - 1). 27 owrt:sigs * Symbolic names of the first 32 signals 28 this architecture provides, in numeric 29 order. Separated by whitespaces. 30 owrt:sig_name_extra * Symbolic names of any additional signals 31 this architecture provides after 32 owrt:sig_count. Separated by 33 whitespaces. 34 owrt:sig_num_extra * Numeric values associated with the 35 signal names provided in 36 owrt:sig_name_extra. Separated by 37 whitespaces. 38 39 Passed via command line 40 ----------------------- 41 Symbol Values Description 42 owrt:libc glibc/uclibc/musl Which C library implementation is in 43 use. 44 owrt:threads yes/no Whether to enable threading support. 45 owrt:ipv6 define/undef Whether to enable IPv6 support. 46 owrt:target_cross * Target architecture's host triplet. 47 owrt:target_cc * C compiler to use. 48 owrt:gccversion * target_cc's version number. 49 owrt:cflags * Additional C compiler flags. 50 owrt:ldflags * Additional linker flags. 51 owrt:staging_dir * Same as OpenWRT buildroot's 52 $(STAGING_DIR). 53 owrt:host_perl_prefix * host-perl installation prefix. 54 55 Passed via version.config 56 ------------------------- 57 Symbol Values Description 58 owrt:perllibpath * Path to perl library files, from the 59 target's point of view.
