From 762f9ef3d9d897b5baf7c91d6e8a7bf371a9b02f Mon Sep 17 00:00:00 2001 From: Rafael Kitover Date: Sat, 2 Mar 2019 16:19:05 -0800 Subject: [PATCH] config: better libtirpc detection Improve the autoconf code for finding libtirpc and do not assume the headers are in /usr/include/tirpc. Also remove this assumption from the `rpc/xdr.h` header in libspl and use the same `#include_next` mechanism that is used for other libspl headers. Include pkg.m4 from pkg-config in config/ for PKG_CHECK_MODULES(), the file license allows this. Include ax_save_flags.m4 and ax_restore_flags.m4 from autoconf-archive, the file licenses are compatible. Use the 2012 versions so as not rely on a more recent autoconf feature AS_VAR_COPY(), which breaks some build slaves. Add new macro library `config/find_system_library.m4` which defines the FIND_SYSTEM_LIBRARY() macro which is a convenience wrapper over using PKG_CHECK_MODULES() with a fallback to standard library locations and some sanity checks. The parameters are: ``` FIND_SYSTEM_LIBRARY(VARIABLE-PREFIX, MODULE, HEADER, HEADER-PREFIXES, LIBRARY, FUNCTIONS, [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND]) ``` `HEADER-PREFIXES` and `FUNCTIONS` are comma-separated m4 lists. For libtirpc we are using: ``` FIND_SYSTEM_LIBRARY(LIBTIRPC, [libtirpc], [rpc/xdr.h], [tirpc], [tirpc], [xdrmem_create], [], [...]) ``` The headers are first checked for without the prefixes and then with. This system works with pkg-config and falls back on checking standard header/library locations, it can be easily overridden by the user by setting the `PREFIX_CFLAGS` and `PREFIX_LIBS` variables which are automatically added to the `./configure --help` output.
