Are there any special reasons why Cygwin Clang is so outdated (see here), version 8, while already version 13 exists?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 Maybe Clang has no support for Cygwin anymore, that's why Cygwin has outdated version?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.

I've been trying to build GCC 10.2 on my Intel MBP. As I've always done, I'm building from source and installing on /usr/local. Trouble is no matter what, the build fails on STAGE2 of bootstrapping. A careful search on all logs (including dependencies) could not point to a single fault. The only thing that stood out was the clang setup from Xcode Command Line Tools. When I run 'gcc -v' on a clean system (empty /usr/local), it outputs:
Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/4.2.1
Apple clang version 12.0.0 (clang-1200.0.32.29)
Target: x86_64-apple-darwin20.2.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin
Trouble is that the target for --with-gxx-include-dir doesn't exist! There is no c++ subfolder, to begin with. Although there is one from the --prefix tree, instead of 4.2.1, there is just a v1 subfolder.
It would appear that there is something terribly wrong with Xcode Command Line Tools. But I can't be sure that this is the cause of my own troubles.
Please, don't answer this post pointing me to a package manager... there's a reason I abandoned those years ago. Also, it would be off-topic to the issue at hand.
I've finally managed to isolate the issue. GCC 10.2 depends on GMP, MPFR, MPC, and ISL libraries. I had them manually installed with the latest version available and fine tuned to my system. I didn't explore if it was a version conflict, or a fine tuning issue, but that broke the build. The solution was to let the script 'contrib/download_prerequisites' (within gcc tree) download the appropriate versions that were built along with GCC.
I also found out that the '--with-gxx-include-dir' target is a non-issue. It isn't supposed to point anywhere in my system. It is a reference to the system that built the "gcc" provided by Xcode Command Line Tools.
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 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.
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.
I need to cross-compile one of the latest GDB server versions (7.4 or 7.5) for iOS. By default configure script does not support such target (arm-apple-darwin). However, I have an idea to merge Apple's open source version of GDB server (based on pretty old version of GDB) with the latest GDB version. Did anyone try this approach? May be there is a better way?
Using mainline GDB is going to be tricky; Apple's version has been forked quite a while ago and porting it won't be trivial. Why do you need specifically 7.4?
If you just need a gdbserver for iOS, try Saurik's patches, although I'm not sure how recent they are.
