I'm using the Bochs emulator and for my class we're using gcc 4.2.1. I believe I've gotten Bochs running, but now I need to compile our programs which are compatible with gcc 4.2/.1.
I understand OSX uses an alias for gcc 4.2.1, but how can I use gcc specifically and not clang?
Edit: GCC 4.6.3 not 4.2.1 sorry
You can install previous version of gcc pretty easily using homebrew.
If you have homebrew installed you can get gcc 4.9 by running
brew install gcc#4.9
After it is installed gcc will still map to the clang that came with your mac. The newly installed gcc will be installed at /usr/local/bin and be called something like gcc-4.
You can find the exact executable name using
ls /usr/local/bin | grep gcc
Hopefully 4.9 is close enough to 4.6 for your purposes.
I have written some effects in C++ (g++) using freeglut on Linux, and I compile them with
g++ -Wall -lglut part8.cpp -o part8
So I was wondering if it is possible to have g++ make static compiled Windows executables that contains everything needed?
I don't have Windows, so it would be really cool, if I could do that on Linux :)
mingw32 exists as a package for Linux. You can cross-compile and -link Windows applications with it. There's a tutorial here at the Code::Blocks forum. Mind that the command changes to x86_64-w64-mingw32-gcc-win32, for example.
Ubuntu, for example, has MinGW in its repositories:
$ apt-cache search mingw
[...]
g++-mingw-w64 - GNU C++ compiler for MinGW-w64
gcc-mingw-w64 - GNU C compiler for MinGW-w64
mingw-w64 - Development environment targeting 32- and 64-bit Windows
[...]
Suggested method gave me error on Ubuntu 16.04: E: Unable to locate package mingw32
===========================================================================
To install this package on Ubuntu please use following:
sudo apt-get install mingw-w64
After install you can use it:
x86_64-w64-mingw32-g++
Please note!
For 64-bit use: x86_64-w64-mingw32-g++
For 32-bit use: i686-w64-mingw32-g++
One option of compiling for Windows in Linux is via mingw. I found a very helpful tutorial here.
To install mingw32 on Debian based systems, run the following command:
sudo apt-get install mingw32
To compile your code, you can use something like:
i586-mingw32msvc-g++ -o myApp.exe myApp.cpp
You'll sometimes want to test the new Windows application directly in Linux. You can use wine for that, although you should always keep in mind that wine could have bugs. This means that you might not be sure that a bug is in wine, your program, or both, so only use wine for general testing.
To install wine, run:
sudo apt-get install wine
Install a cross compiler, like mingw64 from your package manager.
Then compile in the following way: instead of simply calling gcc call i686-w64-mingw32-gcc for 32-bit Windows or x86_64-w64-mingw32-gcc" for 64-bit Windows. I would also use the --static option, as the target system may not have all the libraries.
If you want to compile other language, like Fortran, replace -gcc with -gfortran in the previous commands.
I've used mingw on Linux to make Windows executables in C, I suspect C++ would work as well.
I have a project, ELLCC, that packages clang and other things as a cross compiler tool chain. I use it to compile clang (C++), binutils, and GDB for Windows. Follow the download link at ellcc.org for pre-compiled binaries for several Linux hosts.
From: https://fedoraproject.org/wiki/MinGW/Tutorial
As of Fedora 17 it is possible to easily build (cross-compile) binaries for the win32 and win64 targets. This is realized using the mingw-w64 toolchain: http://mingw-w64.sf.net/. Using this toolchain allows you to build binaries for the following programming languages: C, C++, Objective-C, Objective-C++ and Fortran.
"Tips and tricks for using the Windows cross-compiler": https://fedoraproject.org/wiki/MinGW/Tips
For Fedora:
# Fedora 18 or greater
sudo dnf group install "MinGW cross-compiler"
# Or (not recommended, because of its deprecation)
sudo yum groupinstall -y "MinGW cross-compiler"
I already have gcc version 6.1.0 installed on my computer thanks to XCode:
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 6.1.0 (clang-602.0.53) (based on LLVM 3.6.0svn)
Target: x86_64-apple-darwin15.0.0
Thread model: posix
But I need to install gcc version 4.4.7 and I have tried doing things like brew install gcc447 and such but it always says package not found. Is there a way to install gcc 4.4.7 on OSX 10.10 and have it run as "gcc4" or a similar alias while still keeping the XCode 6.1.0 version?
Homebrew doesn't have recipes for every individual minor version of GCC, only for the major versions like 4.4. Conveniently, though, 4.4.7 is the most recent version of GCC 4.4, so you're fine.
Run brew install gcc44; the compiler will be installed as gcc-4.4.
I need to use the GCC compiler version 4.1.1 on Windows, from a MingGW distribution if possible.
I've been looking for a way to install an older version with the mingw-get installer but I don't find any option to select a specific version. Nevertheless, the official Sourceforge repository doesn't seem to contain the files for this version (http://sourceforge.net/projects/mingw/files/MinGW/Base/gcc/Version4/)
After searching in alternative distributions like Nuwen or TDM-GCC I haven't found a release including GCC 4.1.1.
My question is, is there any place to obtain a MinGW with GCC 4.1.1, or is there another way to obtain this toolchain?
Thanks.
On my Linux platform, I have several versions of gcc.
Under usr/bin I have:
gcc34
gcc44
gcc
Here are some outputs:
$ gcc --version
gcc (GCC) 4.1.2 20080704 (Red Hat 4.1.2-48)
$ gcc44 --version
gcc44 (GCC) 4.4.0 20090514 (Red Hat 4.4.0-6)
I need to use the 4.4 version of gcc however the default seems to the 4.1 one.
I there a way to replace /usr/bin/gcc and make gcc44 the default compiler not using a symlink to /usr/bin/gcc44 ?
The reason why I can't use a symlink is because my code will have to be shipped in a RPM package using mock. mock creates a minimal linux installation from scratch and just install the specified dependencies before compiling my code in it. I cannot customize this "minimal installation".
Ideally, the perfect solution would be to install an official RPM package that replaces gcc with gcc44 as the default compiler. Is there such a package ? Is this even possible/good ?
Additional information
I have to use SCons (a make alternative) and it doesn't let me specify the binary to use for gcc.
I will also accept any answer that will tell me how to specify the gcc binary in my SConstruct file.
One way is to compile and install gcc from source.
See http://old.nabble.com/Choosing-compiler-td4675207.html
From that:
env = Environment()
env.Replace(CC = "my_cc_compiler")
Or, as per the answer to this question,
env['CC'] = 'gcc44'
This is a long way in the past now, but I just thought I'd add the solution I found, which doesn't require changing the SConscript file. It was useful for me as I need to build v8 under centos 5, so possibly it may be useful for someone else too.
CC=gcc44 CXX=g++44 scons
That's it!
