I am in need of GCC 4.1.2 compiler for windows.I don't know much about compilers.If gcc compiler is not available for windows then, are there any similar compilers for windows? Any one please help me out.
If you want the real easy way and you'll have GCC 4.x installed in 2 clicks.
Download CodeBlocks + MinGW
http://prdownload.berlios.de/codeblocks/codeblocks-13.12mingw-setup.exe
http://www.codeblocks.org/downloads/26
[Updated link: Initially did one without mingw]
You can go with these options :
MinGW
Cygwin
Have you tried the two options for windows on Installing GCC Binaries webpage? It is located here.

Successfully installed opencv 4.5.4 in windows under mingw evironment. I was able to compile opencv applications. But is there any easy way to give reference to libraries instead of typing long list of opencv libraries (i.e. something like pkg-config in windows)
For a simple opencv program I need to give reference to 4 libraries.
g++ rotate.cpp -lopencv_core454 -lopencv_highgui454 -lopencv_imgproc454 -lopencv_imgcodecs454
instead do we have some option to give list of libraries through some flags in windows environment.
Thanks
You can actually use pkg-config in Windows. If you use MSYS2 shell is is usually available or it can be installed via pacman.
Are there any special reasons why Cygwin Clang is so outdated (see here), version 8, while already version 13 exists?
For example Ubuntu (apt), MSYS2, MSVC all have version 12.
Also does anyone know (any links?) if there is any very simple way (like docker-based) to build recent Clang for Cygwin? Maybe Clang has no support for Cygwin anymore, that's why Cygwin has outdated version?
See:
https://cygwin.com/packages/summary/clang.html
The reason is very simple, there is no current maintainer.
The previous one has no more available time to dedicate to the project.
Hello,
I have been using Lua 5.1.2 since I begun learning Lua, and I wanted to upgrade to a more recent version, but there aren't any tutorial on how to do it, and I never did something similar. I downloaded the Lua 5.4.0 binaries, but I don't know how to install LuaRocks, which is really useful. (I don't know if this information is useful, but I'm using Windows 7)
Thank you.
so you got 5.4.0 installed?
https://github.com/luarocks/luarocks/wiki/Download
you probably want the 64-bit version of LuaRocks
if it complains, try the 32-bit instead.
just guessing, because most processors are 64-bit these days - unless it's something like a Raspberry Pi, but then you wouldn't be on Win7...
I ran clang++ -v testfile.cpp and found that many standard headers were missing from the directory C:\LLVM\lib\clang\3.9.0\include. I downloaded a pre-built binary of clang 3.9.0 for 32 bit windows from this link.
Can someone please help me sort out this mess and explain me why the standard libraries are missing in the pre-build version of clang? I've searched the web for hours to get the answer and solution to this problem but couldn't find one. Thanks in advance.
why the standard libraries are missing in the pre-build version of clang?
Your Windows binary download comprises only binary build tools
plus a handful of clang-specific headers because you are supposed
to use clang, on Windows, in lieu of another native compiler that provides your
standard library. Similarly if you install clang on Linux you'll build against
the GCC standard library by default.
Your internet search seemingly failed to lead you to Installing clang++ to compile and link on Windows, which
explains how to integrate clang with the mingw-w64 GCC standard library for 32- and/or 64-bit work
in the manner that clang for Windows expects and supports.
I am trying to build Clang following this: http://clang.llvm.org/get_started.html
At step 6 the command ../llvm/configure runs a series of checks and one tells me:
checking whether Clang will select a modern C++ standard library... no
configure: error:
We detected a missing feature in the standard C++ library that was known to be
missing in libstdc++4.6 and implemented in libstdc++4.7. There are numerous
C++11 problems with 4.6's library, and we don't support GCCs or libstdc++ older
than 4.7. You will need to update your system and ensure Clang uses the newer
standard library.
If this error is incorrect or you need to force things to work, you may pass
'--disable-compiler-version-checks' to configure to bypass this test.
I don't know how to resolve this and google searches for libstdc++4.7 did not produce anything useful to me or something I understand. How do I go about replacing / upgrading this? I am on a Mac (10.7.5)
I ran into the same problem. The easiest way to build Clang is to use libc++ instead of libstdc++. If you don't have libc++, you can obtain it by installing XCode 4.2 (or newer) or you can build it yourself by following the instructions here: http://libcxx.llvm.org/
After you have libc++ installed, you can use the --enable-libcpp=yes flag with the configure command.
Just this week, the LLVM & Clang project upped the minimal compiler version requirement to gcc 4.7, with its libstdc++. You'll need to install or build a newer gcc.
Here's a blog post I wrote earlier today about building gcc 4.8 on Ubuntu 12.04 and using that to compile trunk LLVM & Clang. Hope this helps!
i have the same error on mac 10.8.5 xcode 5.0
configure option --enable-libcpp resolve my problem
../llvm/configure --enable-cxx11 --enable-optimized --enable-libcpp
For me this happened because I had the old clang and clang++ that I'd previously built from source (the one I was attempting to build to replace) coming first in my PATH. These were too old. Removing those two files so that the build process would use the clang and clang++ that comes with XCode's Command Line Tools and then rebuilding worked fine.
