From f26057174a00be4deacf4bfd26aa80cf829fd300 Mon Sep 17 00:00:00 2001 From: Robert Haas Date: Tue, 15 Feb 2022 11:38:39 -0500 Subject: [PATCH] Add support for building with ZSTD. This commit doesn't actually add anything that uses ZSTD; that will be done separately. It just puts the basic infrastructure into place. Jeevan Ladhe. I extracted these changes from a larger patch by Jeevan and reran 'autoconf' as the version on Jeevan's machine included some unwanted changes in configure, but otherwise made no changes. --- configure | 271 +++++++++++++++++++++++++++++++++++++ configure.ac | 33 +++++ src/Makefile.global.in | 1 + src/include/pg_config.h.in | 9 ++ 4 files changed, 314 insertions(+) diff --git a/configure b/configure index 9305555658..f07f689f1a 100755 --- a/configure +++ b/configure @@ -650,6 +650,7 @@ CFLAGS_ARMV8_CRC32C CFLAGS_SSE42 have_win32_dbghelp LIBOBJS +ZSTD LZ4 UUID_LIBS LDAP_LIBS_BE @@ -700,6 +701,9 @@ with_gnu_ld LD LDFLAGS_SL LDFLAGS_EX +ZSTD_LIBS +ZSTD_CFLAGS +with_zstd LZ4_LIBS LZ4_CFLAGS with_lz4 @@ -869,6 +873,7 @@ with_libxslt with_system_tzdata with_zlib with_lz4 +with_zstd with_gnu_ld with_ssl with_openssl @@ -898,6 +903,8 @@ XML2_CFLAGS XML2_LIBS LZ4_CFLAGS LZ4_LIBS +ZSTD_CFLAGS +ZSTD_LIBS LDFLAGS_EX LDFLAGS_SL PERL @@ -1577,6 +1584,7 @@ Optional Packages: use system time zone data in DIR --without-zlib do not use Zlib --with-lz4 build with LZ4 support + --with-zstd build with ZSTD support --with-gnu-ld assume the C compiler uses GNU ld [default=no] --with-ssl=LIB use LIB for SSL/TLS support (openssl) --with-openssl obsolete spelling of --with-ssl=openssl @@ -1606,6 +1614,8 @@ Some influential environment variables: XML2_LIBS linker flags for XML2, overriding pkg-config LZ4_CFLAGS C compiler flags for LZ4, overriding pkg-config LZ4_LIBS linker flags for LZ4, overriding pkg-config + ZSTD_CFLAGS C compiler flags for ZSTD, overriding pkg-config + ZSTD_LIBS linker flags for ZSTD, overriding pkg-config LDFLAGS_EX extra linker flags for linking executables only LDFLAGS_SL extra linker flags for linking shared libraries only PERL Perl program @@ -9034,6 +9044,146 @@ fi done fi +# +# ZSTD +# +{ $as_echo "$as_me:${as_lineno-$LINENO}: checking whether to build with ZSTD support" >&5 +$as_echo_n "checking whether to build with ZSTD support...
