Currently I see v8 here on Cygwin while llvm is now at v12. I had tried to build v12 in Cygwin by simply running along the instructions on the llvm page. But I failed at a number of options / packages in the past and only got clang and a few tools like clang-format to run under Cygwin. I apologise, but I really have no clue about building anything properly for Cygwin (yet). Cheers, Andreas ^ permalink raw reply [flat|nested] 7+ messages in thread

Unfortunately the package is without maintainer, and volunteers to take over are lacking. https://cygwin.com/packages/summary/clang.html Motivation/Need is a good starting point for becoming a maintainer, feel free to post here your issues in trying to compile it; maybe we can help you Marco ^ permalink raw reply [flat|nested] 7+ messages in thread

Thank you for your kind hints. :) > Unfortunately the package is without maintainer, and volunteers > to take > over are lacking. I was not sure on this part. Good to know, for now I was not expecting anything, just being curious. But since I am interested, I will spent some time to look into it at some point. Although I feel not very confident achieving much with my limited knowledge. I will get back to you, once I have concrete questions I can articulate.

But I failed at a number of options / packages in the past and only got clang and a few tools like clang-format to run under Cygwin. I apologise, but I really have no clue about building anything properly for Cygwin (yet). Install the latest llvm and clang *source* packages; and binary packages: cygport, which pulls in all the usual tools, but also add cmake, gnupg2, ninja, cygwin-devel, libc++-devel, libc++abi-devel, libedit-devel, libffi-devel, libllvm-devel, libncurses-devel, libpolly-devel, libunwind-devel, libxml2-devel, zlib-devel, python3-devel, python3-recommonmark, python3-setuptools, and python3-sphinx; change to the llvm source directory containing the llvm.cygport file; edit llvm.cygport, and bump the major version 1 at a time, e.g. 9.0.1, 10.0.1 11.1.0, 12.0.0, including libllvm{9,10,11,12}, libpolly{9,10,11,12}, and save; then run: $ cygport llvm.cygport download all check Pay attention to: any warning or error messages about required packages missing, some of which may be lib...-devel, which you have to install before retrying the build; and build errors, which you have to resolve. After a successful build, you will have binary and source tar and hint files under llvm-#-1.*86*/dist/llvm/ which you may install on your system using: $ tar -xv -C / -f llvm-#-1.*86*/dist/llvm/llvm-#-1.tar.xz similarly for prerequisite dependencies and corequisite package tars under: $ ls llvm-#-1.*86*/dist/llvm/{,*/}*-#-1.tar.xz as packages are built under a virtual root directory, which you can see under llvm-#-1.*86*/inst/... Then repeat the process for clang using each recently built and installed llvm. -- Take care.

You can also browse the cygport and patch files required at: https://cygwin.com/git-cygwin-packages/?p=git/cygwin-packages/llvm.git https://cygwin.com/git-cygwin-packages/?p=git/cygwin-packages/clang.git and you can git clone those projects from the listed URLs as a basis for building and upgrading: llvm cygport has already been updated there for 9.0.1. Once you have installed cygport you can browse the local docs using: $ cygstart /usr/share/doc/cygport/html/manual/index.html for more information on what's going on. -- Take care.
