I have installed cygwin in my windows xp, and I am trying to compile boost version 1.33.1, but I get error when I try to use build-boost.sh This is what I am doing: rodrigo.pinho@localhost /usr/src/boost-1.33.1-2 $ ls -ls total 81568 0 drwxrwx---+ 2 rodrigo.pinho mkgroup-l-d 0 Nov 17 09:26 boost-devel 4 -rwxr-x---+ 1 rodrigo.pinho mkgroup-l-d 1945 Jan 18 2006 boost.README 81552 -rwxr-x--- 1 rodrigo.pinho mkgroup-l-d 83507200 Dec 7 2005 boost_1_33_1.tar 8 -rwxr-x---+ 1 rodrigo.pinho mkgroup-l-d 6020 Jan 18 2006 build-boost.sh 0 drwxrwx---+ 2 rodrigo.pinho mkgroup-l-d 0 Nov 17 09:26 patches 4 -rwxr-x---+ 1 rodrigo.pinho mkgroup-l-d 877 Dec 7 2005 setup.hint rodrigo.pinho@localhost usr/src/boost-1.33.1-2 $ ./build-boost.sh : command not foundine 3: : command not foundine 16: ./build-boost.sh: line 26: syntax error near unexpected token `&&' '/build-boost.sh: line 26: ` && cp -pRf -t "boost-${package_ver}" "${this_script}" \ When I open the file build-boost.sh, I checked that in line 3 and line 16 there was empty line. I have no expirience with boost in linux, it is my first time, and beacause this I am using cygwin. Anyone can point me what I am doing wrong ? Version of my bash is 3.2.5-6.
