I am trying to install GCC on my local system.

I am referring this

I have successfully completed the following steps:

  1. Install Cygwin

  2. Install Required Cygwin Packages

     C:\cygwin64>setup-x86_64.exe -q -P wget -P gcc-g++ -P make -P diffutils -P libmpfr-devel -P libgmp-devel -P libmpc-devel

  3. Download, Build and Install the Latest GCC

    $ wget http://ftpmirror.gnu.org/gcc/gcc-9.2.0/gcc-9.2.0.tar.gz
$ tar xf gcc-9.2.0.tar.gz
$ mkdir build-gcc
$ cd build-gcc

After this while configuring the gcc-9.2.0 using the below command I am facing the following error:

    $ ../gcc-9.2.0/configure --enable-languages=c,c++ --disable-bootstrap --disable-shared
error:
    configure: creating ./config.status
    ./config.status: line 470: syntax error near unexpected token `)'
    ./config.status: line 470: `    *\'*) ac_optarg=`$as_echo "$ac_optarg" | sed "s/'/'\\\\\\\\''/g"` ;;'

Any solution for this or alternate website link for downloading latest gcc binaries for windows will be highly appreciated.

    Do you need to use Cygwin? Unless you really need the POSIX compatibility layer it provides, I've found Cygwin to be more trouble than it's worth. – user4581301 Dec 04 '19 at 04:46
  • Agreed, if at all possible I would use the windows 10 Linux For Windows subsystem. – SoronelHaetir Dec 04 '19 at 05:13
  • I just want use latest gcc compiler for c++ and debugging capability. I found the MinGW builds are supporting old gcc releases, which does not provide latest C++ code support – Ranjan Dec 04 '19 at 09:08
  • The really well-known mingw distributions, or at least the ones google dumps you at, are mostly antiques that barely support C++11. To gett an up-to-date toolchain the instructions I would give are too close to [this answer](https://stackoverflow.com/a/30071634/4581301) to be worth rewriting. I add on a few extra packages like ssl and curl. Msys and the surrounding environment are good at keeping things up to date as well. – user4581301 Dec 04 '19 at 17:55
  • I just tried it myself, admittedly on an existing Cygwin installation rather than a new one, and was not able to reproduce the problem. After running `configure` I got a `config.status` with the exact same line 470: `*\'*) ac_optarg=`$as_echo "$ac_optarg" | sed "s/'/'\\\\\\\\''/g"` ;;`. It's conceivable the problem is with your shell. Although `configure` is supposed to produce shell-agnostic code, this may not always succeed. So what shell are you using? Just the standard bash shell or something else? – Iguananaut Dec 06 '19 at 10:20
  • FWIW I have `$ bash --version` `GNU bash, version 4.4.12(3)-release (x86_64-unknown-cygwin)` – Iguananaut Dec 06 '19 at 10:21
  • @Iguananaut as I'm using windows 10, so it is command prompt actually. – Ranjan Dec 16 '19 at 19:30
  • You should run the bash shell that comes with Cygwin instead. – Iguananaut Dec 17 '19 at 11:05

Personally I try to avoid Cygwin as it has a compatibility layer, so the resulting executables are not 100% native. With MinGW or the newer MinGW-w64 you do get 100% native Windows .exe and .dll files.

If you're looking for the latest GCC version with MinGW-w64 check out: http://winlibs.com

At the time of this writing GCC 9.3.0 is the latest version, but http://winlibs.com already has Windows builds of snapshots of the upcoming GCC 10.
