О чём код?
#!/bin/sh # # Select where system include files should be sought. If the user specified a # sysroot, validate it. # # A separate script so it can be shared between autoconf and meson. PG_SYSROOT=$1 if test x"$PG_SYSROOT" = x"" ; then # This is far more complicated than it ought to be. We first ask # "xcrun --show-sdk-path", which seems to match the default -isysroot # setting of Apple's compilers. PG_SYSROOT=`xcrun --show-sdk-path 2>/dev/null` # That may fail, or produce a result that is not version-specific (i.e., # just ".../SDKs/MacOSX.sdk"). Using a version-specific sysroot seems # desirable, so if the path is a non-version-specific symlink, expand it. if test -L "$PG_SYSROOT"; then if expr x"$PG_SYSROOT" : '.*[0-9]\.[0-9][^/]*$' >/dev/null ; then : okay else PG_SYSROOT=`expr "$PG_SYSROOT" : '\(.*\)/'`/`readlink "$PG_SYSROOT"` fi fi # If there are still not digits in the directory name, try # "xcrun --sdk macosx --show-sdk-path"; and if that still doesn't work, # fall back to asking xcodebuild, which is often a good deal slower. if expr x"$PG_SYSROOT" : '.*[0-9]\.[0-9][^/]*$' >/dev/null ; then : okay else PG_SYSROOT=`xcrun --sdk macosx --show-sdk-path 2>/dev/null` if expr x"$PG_SYSROOT" : '.*[0-9]\.[0-9][^/]*$' >/dev/null ; then : okay else PG_SYSROOT=`xcodebuild -version -sdk macosx Path 2>/dev/null` fi fi fi # Validate the result: if it doesn't point at a directory, ignore it. if test x"$PG_SYSROOT" != x"" ; then if test -d "$PG_SYSROOT" ; then echo $PG_SYSROOT fi fi
