Go to and download the source (e.g., mpfr-3.0.1.tar.bz2).The version from Cygwin is older and will not work. It is required for MFPR and thus for GCC. GMP is a library for arbitrary precision arithmetic. Go to and download the source (e.g., gmp-5.0.2.tar.bz2).This is where you'll extract and work with each GCC-related package, including GCC itself. You can check package version numbers and statuses with the cygcheck command:īash binutils bzip2 cygwin gcc-core gcc-g++ gcc-java gzip m4 make unzip zipĪn example of the ' Cygwin Package Information output:įirst, create a workspace directory to build in (e.g., mkdir /usr/local/contrib). gcc-java (needed only if you want to install Java only jar command is needed found in the Devel section).

gzip (version 1.2.4 or later found in the Base section).

If something is missing or outdated, download it using the setup.exe utility from the Cygwin site ( ): (The new GCC will be installed under /usr/local/bin you'll still have the old GCC under /usr/bin or /bin).Ĭheck that you have following packages under Cygwin. This process was tested using the versions of Cygwin and the prerequisite packages listed below.Īfter you install GCC >= 4.3, some things like exception handling or shared code may not work (read more here), so install at your own risk. This how-to is provided without any guarantees whatsoever.
