I had an old version of mingw on my computer that compiles programs to 32 bit. Now I want to compile to 64 bit, so I downloaded the new mingw installer. It tried uninstalling and installing several times with different versions (x86_64 option each time), but some files appear to be missing each time, at least make.exe. There's no make.exe in any of the mingw subfolders, only mingw32-make.exe in
C:\Program Files\mingw-w64\x86_64-6.3.0-posix-seh-rt_v5-rev1\mingw64\bin
I'm relatively new to c++, so maybe I'm overlooking something? https://sourceforge.net/p/mingw-w64/wiki2/Make/ mentions you can copy make to the bin folder, but where do I copy it from?
mingw32-make.exe is the one you want to use. It is the version of make shipped with MinGW-w64. A plain make.exe does not exist. Don’t get confused by the name. You use mingw32-make.exe no matter if you want to produce 32bit or 64bit binaries.
You can create a symbolic link make.exe target to mingw32-make.exe, this way you can run make instead of mingw32-make. I found Git Bash is very useful for running Linux like tools on Windows.

I'm going to teach students to use SFML with C++, and I'm afraid the school doesn't have visual studio C++ installed, or will be a bit heavy to use for those students.
I want to have a plan B and have the option of a simple makefile that I can build on windows with SFML.
https://www.sfml-dev.org/download/sfml/2.5.1/ this page offers binaries compiled with different, specific versions of mingw with their respective mingw package links, unfortunately mingw doesn't include an unix terminal, like the one included with git-bash, so I can run a makefile.
What are the steps required to have a problem unix terminal, running in windows, minsys, msys2 or not, that can work well with those mingw packages? I have trouble finding help or proper instructions.
You want https://www.msys2.org/
It provides bash terminal and already contains mingw compiler. Perhaps it even has SFML packages already.
I am trying to install MinGW but it's always failing to install.
on windows 7
link of the program:
https://sourceforge.net/projects/mingw/files/latest/download
Tar zips are not generally for windows users the downlink should be a windows installer mingw-get-setup.EXE thus (not a GnuZip)
Also if your trying to unpack 32bit collections the question is which architecture do you need, certainly 32.exe will run on 64, but 64.exe will NOT work on 32.
Current build is 32bit "Although (currently) offering only a 32-bit compiler suite, all of MinGW's software will execute on the 64bit Windows platforms."
get it from official https://osdn.net/projects/mingw/releases/
latest link I got was
https://osdn.net/frs/redir.php?m=liquid&f=mingw%2F68260%2Fmingw-get-0.6.3-mingw32-pre-20170905-1-bin.zip
once you have a valid windows .zip file, right click to "extract" then the exe should be in the bin folder.
Then it's just you on your own, and the myriad of instructions from google.
MinGW is a compiler generating files for the Windows platform, but MinGW itself can also be run on other platforms (like Linux for example).
What you need is are Windows binaries of MinGW.
But MinGW is a bit outdated and only supports 32-bit Windows.
I would really recommend using MinGW-w64.
Standalone build of MinGW-w64 for Windows (both 32-bit and 64-bit) are available at https://winlibs.com/ just download the archive and extract it. Then all the tools you need will be in the mingw32/bin or mingw64/bin folder.
If you're not very familiar with command line tools you should really use an IDE. There are some instructions on https://winlibs.com/ on how to use MinGW-w64 with Code::Blocks.
If on the other hand you are very familiar with command line or the Linux shell you should take a look at MSYS2 which also allows installing MinGW-w64 with it's pacman tool.
I would like to upgrade my old GCC compiler to v. 4.8.1.
Currently I'm using Code::Blocks IDE (nightly build, svn 8982), and my compiler is GCC 4.4.1.
I downloaded fresh GCC from their site - gcc.gnu.org
From what I've read in documentation, they say that I should first build compiler by myself. Afterwards, they throw something like this:
% mkdir objdir
% cd objdir
% srcdir/configure [options] [target]
However, I completly have no idea what to do with these lines.
And even if I did, afterwards come maaany lines with some additional options, where I am even more lost then before.
I don't know if there is any easy way of installing it, but from what I've read here, I can download MSYS from MinGW and it will do everything(I hope?) for me. However, from what I see there, it says that MinGW comes with already built version of GCC, meaning I won't be able to use mine anyway. Am I right? If yes, what should I do to build and use GCC? If not, then will I be able to easily install GCC after downloading MSYS?
Thanks in advance.
I can download MSYS from MinGW
YOu can.
and it will do everything(I hope?) for me.
It won't. MSys provides environment for building software that requires unix-like environment. To be more precise - autotools. If you aren't familiar with *nix build process (configure script), Mingw won't really help you.
However, from what I see there, it says that MinGW comes with already built version of GCC,
Yes, version 4.7.2 at the moment.
meaning I won't be able to use mine anyway. Am I right?
No. If you don't add Mingw/MSys to your PATH, you can keep multiple different installations on the same machine. It also SHOULD be possible to use multiple different versions of gcc within the same installation of mingw, but things can get messy here. (gcc3 and gcc4 should be able to exist, not sure about 4.7.2 and 4.8.1)
If yes, what should I do to build and use GCC?
You should search for precompiled binaries provided by somebody else. Compiling gcc yourself is possible, but for you (i.e. if you aren't arleady familiar with msys) it might not be worth the effort.
Either you could try http://mingw-w64.sourceforge.net/ or mingw-nuwen. Mingw provided by nuwen is 32bit only, but is very easy to install. The problem is that standard mingw distribution includes update tool (with "mingw uppdate" and "mingw upgrade" you can upgrade installed packages to their latest version), bug "mingw-nuwen" doesn't have such tool.
Because you say
However, I completly have no idea what to do with these lines.
You should either use precompiled mingw provded by somebody else, or use another compiler. If you don't really need bleeding-edge C++11 support ON WINDOWS, use visual studio express.
I've downloaded MinGW with mingw-get-inst, and now I've noticed that it cannot compile for x64.
So is there any 32-bit binary version of the MinGW compiler that can both compile for 32-bit Windows and also for 64-bit Windows?
I don't want a 64-bit version that can generate 32-bit code, since I want the compiler to also run on 32-bit Windows, and I'm only looking for precompiled binaries here, not source files, since I've spent countless hours compiling GCC and failing, and I've given up for a while. :(
AFAIK mingw targets either 32 bit windows or 64 bit windows, but not both, so you would need two installs. And the latter is still considered beta.
For you what you want is either mingw-w64-bin_i686-mingw or mingw-w64-bin_i686-cygwin if you want to compile for windows 64. For win32, just use what you get with mingw-get-inst.
See http://sourceforge.net/apps/trac/mingw-w64/wiki/download%20filename%20structure for an explanation of file names.
I realize this is an old question. However it's linked to the many times the question has been repeated.
I have found, after lots of research that, by now, years later, both compilers are commonly installed by default when installing mingw from your repository (i.e. synaptic).
You can check and verify by running Linux's locate command:
$ locate -r "mingw32.*[cg]++$"
On my Ubuntu (13.10) install I have by default the following compilers to choose from... found by issuing the locate command.
/usr/bin/amd64-mingw32msvc-c++
/usr/bin/amd64-mingw32msvc-g++
/usr/bin/i586-mingw32msvc-c++
/usr/bin/i586-mingw32msvc-g++
/usr/bin/i686-w64-mingw32-c++
/usr/bin/i686-w64-mingw32-g++
/usr/bin/x86_64-w64-mingw32-c++
/usr/bin/x86_64-w64-mingw32-g++
Finally, the least you'd have to do on many systems is run:
$ sudo apt-get install gcc-mingw32
I hope the many links to this page can spare a lot of programmers some search time.
for you situation, you can download multilib (include lib32 and lib64) version for Mingw64:
Multilib Toolchains(Targetting Win32 and Win64)
By default it is compiled for 64bit.You can add -m32 flag to compile for 32bit program.
But sadly,no gdb provided,you ought to add it manually.
Because according to mingw-64's todo list, gcc multilib version is done,but gdb
multilib version is still in progress,you could use it maybe in the future.
Support of multilib build in configure and in gcc. Parts are already present in gcc's 4.5 version by using target triplet -w64-mingw32.
gdb -- Native support is present, but some features like multi-arch support (debugging 32-bit and 64-bit by one gdb) are still missing features.
mingw-64-todo-list
I've gone to http://sourceforge.net/project/showfiles.php?group_id=2435, downloaded the Automated MinGW Installer for MinGW 5.1.4 and at the same time the GNU Source-Level Debugger Release Candidate: GDB 6.8-3. I've then installed MinGW base tools into C:\MinGW. No problem so far.
However when I come to install the gdb debugger it has a lot of files and folders with the same names as some already installed but the files are different to those already installed. e.g C:\MinGW\include\bfd.h is 171 KB but gdb-6.8-mingw-3\include\bfd.h is 184 KB.
How do I add gdb to MinGW without breaking what's already installed?
In a command prompt I browsed to C:\MinGW\bin and ran:
mingw-get.exe install gdb
That fixed it for me. Not sure if it matters but I have C:\MinGW\bin in my path (guess I probably didn't need to browse to C:\MinGW\bin).
The Current Release (5.2.1) version of gdb at the project files page has always worked for me. The download is a stand-alone .exe, you don't need anything else.
But I'll bet the .exe in the 6.8 package will work, too. I'd try using just the .exe, and then if there are problems, try extracting the other files from the 6.8 package. (Though that may cause problems with the rest of the MinGW installation.)
Update: There seems to be a 7.something version. I haven't tested it thoroughly, but it seems to work, even with gcc 3.
Get Wascana Desktop Developer. It combines MinGW, gcc, Eclipse and gdb in one package.
You can safely overwrite the files prepackaged with MinGW with the (newer) ones from the gdb tarball. You can also choose not to overwrite them - just make sure to pick either one set, i.e. avoid mixing files from the older and the newer package.
Most of the offending files are probably not really relevant to you anyway. For example, the files belonging to the libbfd library aren't required for gdb's day to day operation, they're used if you want to extend the debugger or write debugging tools yourself.
At any rate, make a backup of the mingw directory before untarring the new release. It's very easy since MinGW is self-contained in that directory. That way, if anything should malfunction, you can just delete the directory and restore from the backup.
Usually for installing gdb in windows, You have to 2 ways to install:
1) use ready-made binaries that were build and compiled from GNU gdb by some provider (easy to install)
use TDM-GCC binaries provided from the following URL and that is including inturn the gcc complier and also gdb debugger.
http://tdm-gcc.tdragon.net/
use Equation package inside which GNU GDB was already compiled and built.
http://www.equation.com/servlet/equation.cmd?fa=gdb
2) use minimal mingw or cygwin package then after install gdb inside it.
Install either mingw or cygwin inside which GDB is already shipped
Open cygwin or mingw terminal and just type the following to make sure it is already installed
$ gdb --version
Hint: if you did not find gdb installed, simply open the cygwin or mingw package installer and make sure you already check gdb
Hint: getting and installing a debug build of the OHRRPGCE is providing useful information about crashes.
From cygwin or mingw terminal, Start gdb using the following
c:\mingw\bin\gdb.exe program_to_debug.exe
REF: http://rpg.hamsterrepublic.com/ohrrpgce/GDB_on_Windows
The TDM GCC/MinGW32 builds installer includes gdb. It's gcc 4.4.x with all the core binary packages required for basic Windows development, and is widely used without any unusual problems.
