Edward Berner sends the following description on how to statically link Fossil using the Musl libc. See http://www.musl-libc.org/ for the Musl Libc source code:
$ tar zxf musl-0.9.9.tar.gz $ cd musl-0.9.9 $ ./configure --prefix=$HOME/musl --disable-shared $ make $ mkdir $HOME/musl $ make install # cd to a fossil source directory $ PATH=$PATH:$HOME/musl/bin $ cd compat/zlib $ chmod +x ./configure $ CC=musl-gcc ./configure --static $ make $ cd ../.. $ ./configure --with-openssl=none --with-zlib=compat/zlib --static CC=musl-gcc $ make
After the [6e685da3904a3] check-in, the "chmod +x" step should no longer be necessary, though it is harmless to retain it.
