How to full (with all features - ACL support / Xattr support / xxhash library/ zstd library) install (compiling) rsync v3.2.3 on Mac?

First, install Homebrew:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

And then execute the following command:

brew install xxhash; brew install zstd; brew install lz4; brew install openssl;
export LDFLAGS="-L/usr/local/opt/openssl@1.1/lib";
export CPPFLAGS="-I/usr/local/opt/openssl@1.1/include";
echo 'export PATH="/usr/local/opt/openssl@1.1/bin:$PATH"' >> ~/.zshrc;

Try again to execute: ./configure

UPDATE -- 06/05/2021

You can try to paste the following script into the terminal and run:

cd ~/Desktop;
curl -OL https://github.com/Cyan4973/xxHash/archive/v0.8.0.tar.gz;
tar -xvf v0.8.0.tar.gz;
cd xxHash-0.8.0;
make -j4;
sudo make install;

cd ~/Desktop;
curl -OL https://github.com/lz4/lz4/archive/v1.9.3.tar.gz;
tar -xvf v1.9.3.tar.gz;
cd lz4-1.9.3;
make -j4;
sudo make install;

cd ~/Desktop;
curl -OL https://www.openssl.org/source/openssl-1.1.1k.tar.gz;
tar -xvf openssl-1.1.1k.tar.gz;
cd openssl-1.1.1k ;
./config;
make -j4;
sudo make install;

cd ~/Desktop;
curl -OL https://github.com/facebook/zstd/archive/v1.5.0.tar.gz;
tar -xvf v1.5.0.tar.gz;
cd zstd-1.5.0 ;
make -j4;
sudo make install;

cd ~/Desktop;
curl -OL https://rsync.samba.org/ftp/rsync/src/rsync-3.2.3.tar.gz;
tar -xvf rsync-3.2.3.tar.gz;
cd rsync-3.2.3;
./configure;
make -j4;
sudo make install;

cd /usr/local/bin;
./rsync --version;

Finding all the software package source code download url is a tedious job. If you are a "script purist," you can indeed do this. But I think Homebrew can really free the programmer's hands and get rid of the nightmare of "submerged in the ocean of curl and printlog".

How do I know the download url of each package? Google a few days, in the end still have to refer to the Homebrew formulae Code:

xxhash：https://formulae.brew.sh/formula/xxhash#default

lz4: https://formulae.brew.sh/formula/lz4#default

openssl1.1: https://formulae.brew.sh/formula/openssl@1.1#default

zstd: https://formulae.brew.sh/formula/zstd#default

While I think that @Janyee gave the correct answer and should get credited, maybe this helps others that ran into a similar issue of library linking errors, too.

Compiling rsync 3.2.4 (the same happens for rsync 3.2.3) on macOS 10.12.x Sierra with manual installed external libraries xxHash, zstd, lz4, openssl, popt, zlib in non standard folders gave the following error on make, even though ./configure reported rsync 3.2.4 configuration successful:

Compiling without extra libs worked:

$ ./configure --prefix=/NonStandardDir/rsync/rsync-3.2.4 --disable-openssl --disable-xxhash --disable-zstd --disable-lz4 --disable-roll-simd --disable-md2man

The config.log and the ./configure script output gave hints on missing libraries. Executing make generated files like ~/Library/Logs/DiagnosticReports/conftest_….crash. Those reports clearly that the library is searched in the wrong standard place: Library not loaded: /usr/local/lib/liblz4.1.dylib

That the dynamic libraries liblz4.1.9.3.dylib, libzstd.1.5.2.dylib and libxxhash.0.8.1.dylib were linked incorrectly could also be proofed by:

$ otool -L /NonStandardFolder/lz4/lz4-1.9.3/usr/local/lib/liblz4.1.9.3.dylib  
# -> Output: … /usr/local/lib/liblz4.1.dylib (compatibility version 1.0.0, current version 1.9.3)…

As popt, openssl and zlib weren't affected, because --prefix was set in the ./configure command, the solution is to recompile the incorrectly linked libs with the right prefix for the destination:

$ export PREFIX="/NonStandardFolder/lz4/lz4-1.9.3" && make && make install

The mistake was to set DESTDIR instead of PREFIX while executing the make command.

Check the dynamic library again and it should be correctly linked:

$ otool -L /NonStandardFolder/lz4/lz4-1.9.3/lib/liblz4.1.9.3.dylib 
# -> Output: … /NonStandardFolder/lz4/lz4-1.9.3/lib/liblz4.1.dylib (compatibility version 1.0.0, current version 1.9.3)…

After recompiling the libs lz4, xxHash, zstd, something like the following (adapt to your folder structure) should work to compile rsync:

$ cd /SourcecodeFolder/rsync/rsync-3.2.4

$ make clean

$ ./configure --prefix=/NonStandardDir/rsync/rsync-3.2.4 --disable-debug --disable-md2man --with-rsyncd-conf=/NonStandardDir/rsync/rsync-3.2.4/configuration/rsyncd.conf --with-included-popt=no --with-included-zlib=no --enable-ipv6 --disable-roll-simd CPPFLAGS="-I/NonStandardDir/openssl/openssl-1.1.1n/include -I/NonStandardDir/lz4/lz4-1.9.3/usr/local/include -I/NonStandardDir/zstd/zstd-1.5.2/include -I/NonStandardDir/xxHash/xxHash-0.8.1/include -I/NonStandardDir/popt/popt-1.18/include -I/NonStandardDir/zlib/zlib-1.2.11/include" LDFLAGS="-L/NonStandardDir/openssl/openssl-1.1.1n/lib -L/NonStandardDir/lz4/lz4-1.9.3/lib -L/NonStandardDir/zstd/zstd-1.5.2/lib -L/NonStandardDir/xxHash/xxHash-0.8.1/lib -L/NonStandardDir/popt/popt-1.18/lib -L/NonStandardDir/zlib/zlib-1.2.11/lib"

$ make

$ make test
