Need help installing boost-1.69.0 on osX 11.2.1 BigSur

[harshakokel]

Hello,

I find myself needing boost-1.69.0 for a project and I am trying to follow following steps to get that version.

1. Copy the 1.69.0 tar.gz to brew cache
   • mv boost-1.69.0.tar.bz2 $(brew --cache -s boost)
2. Revert home brew formula to 1.69.0
   • open the formula by brew edit boost
   • copy paste the 1.69.0 formula
3. Install boost from source
   • brew install --build-from-source boost

However, I am facing the following error and the boost is not installed successfully.

==> ./bootstrap.sh --prefix=/usr/local/Cellar/boost/1.69.0 --libdir=/usr/local/Cellar/boost/1.69.0/lib --with-icu=/usr/local/opt/icu4c --without-librar
==> ./b2 headers
==> ./b2 --prefix=/usr/local/Cellar/boost/1.69.0 --libdir=/usr/local/Cellar/boost/1.69.0/lib -d2 -j12 --layout=tagged-1.66 --user-config=user-config.ja

Can someone please guide me on what can I do to resolve this? Or if there is any better way to install 1.69.0?

I also tried building from source as follows:

• Unpack and go into the directory: tar -xzf boost_1_690_0.tar.gz
• cd boost_1_69_0
• Configure: ./bootstrap.sh
• Build: ./b2
• Install: ./b2 install

But I faced clang: error: unknown argument: '-fcoalesce-templates'.

Any help would be greatly appreciated. Thanks in advance.
