That +# is useful when tunnelling the segment token into the external build process +# via a --prefix configure switch, for example. +# +# When another dynamic library or an executable links against such a dynamic +# library, the path recorded in the former to locate the latter is rewritten +# according to the below %action table. The result path consists of the prefix +# from the action table followed by the suffix of the dynamic library's install +# name. If the special segment token does not contain the optional "." after +# the "@", the suffix consists of all segments after the special token segment. +# If the special token segment does contain the optional ".", then the suffix +# consists of just the last segment of the original install name. +# +# That latter case is useful for libraries from external modules, where the +# external build process locates them in some sub-directory. + +sub action($$$) +{ + # The @__VIA_LIBRARY_PATH__ thing has no magic meaning anywhere + # (here in LO or to the dynamic linker), it is effectively a + # comment telling that this library is supposed to have been found + # by the dynamic linker already in DYLD_LIBRARY_PATH. + + my %action = + ('app/UREBIN/URELIB' => '@executable_path/../Frameworks', + 'app/OOO/URELIB' => '@executable_path/../Frameworks', + 'app/OOO/OOO' => '@executable_path/../Frameworks', + 'app/SDKBIN/URELIB' => '@__VIA_LIBRARY_PATH__', + 'app/NONE/URELIB' => '@__VIA_LIBRARY_PATH__', + 'app/NONE/OOO' => '@__VIA_LIBRARY_PATH__', + 'app/NONE/NONE' => '@__VIA_LIBRARY_PATH__', + 'shl/URELIB/URELIB' => '@loader_path', + 'shl/OOO/URELIB' => '@loader_path', + 'shl/OOO/OOO' => '@loader_path', + 'shl/URELIB/OOO' => '@loader_path', + 'shl/OXT/URELIB' => '@executable_path/urelibs', + 'shl/NONE/URELIB' => '@__VIA_LIBRARY_PATH__', + 'shl/NONE/OOO' => '@__VIA_LIBRARY_PATH__', + 'shl/NONE/NONE' => '@loader_path'); + my ($type, $loc1, $loc2) = @_; + my $act = $action{"$type/$loc1/$loc2"}; + die "illegal combination $type/$loc1/$loc2" unless defined $act; + return $act; +} + +@ARGV >= 2 or die 'Usage: app|shl UREBIN|URELIB|OOO|SDKBIN|OXT|NONE <filepath>*'; +$type = shift @ARGV; +$loc = shift @ARGV; +foreach $file (@ARGV) +{ + my $call = "otool -L $file"; + open(IN, "-|", $call) or die "cannot $call"; + my $change = ""; + while (<IN>) + { + if (m'^\s*(((/.*)?/)?@_{50}([^/]+)(/.+)) \(compatibility version \d+\.\d+\.\d+, current version \d+\.\d+\.\d+\)\n$') + { + $change .= " -change $1 " . action($type, $loc, $4) . $5; + } + elsif (m'^\s*(((/.*)?/)?@\._{50}([^/]+)(/.+)?(/[^/]+)) \(compatibility version \d+\.\d+\.\d+, current version \d+\.\d+\.\d+\)\n$') + { + $change .= " -change $1 " . action($type, $loc, $4) . $6; + } + } + close(IN) or die "got $? from $call"; + if ($change ne "") + { + $call = "$ENV{'INSTALL_NAME_TOOL'} $change $file"; + system($call) == 0 or die "cannot $call"; + } +} |
