[llvm-dev] Clang is a resource hog, the installers for Windows miss quite some files, and are defect!
Hi @ll, BUGS #1 & #2: ~~~~~~~~~~~~~ The installer LLVM-10.0.0-win64.exe dumps the following DUPLICATE files in "C:\Program Files\LLVM\bin", WASTING about 500MB disk space, which is nearly a third of the disk space occupied by the whole package: | DIR "C:\Program Files\LLVM\bin" /O:-S ... | 25.03.2020 12:15 83.258.880 clang-cl.exe | 25.03.2020 12:03 83.258.880 clang.exe | 25.03.2020 12:15 83.258.880 clang++.exe | 25.03.2020 12:15 83.258.880 clang-cpp.exe ... | 25.03.2020 12:15 57.812.480 lld-link.exe | 25.03.2020 12:05 57.812.480 lld.exe | 25.03.2020 12:15 57.812.480 ld.lld.exe | 25.03.2020 12:15 57.812.480 ld64.lld.exe | 25.03.2020 12:15 57.812.480 wasm-ld.exe ... | 25.03.2020 12:15 18.182.144 llvm-ranlib.exe | 25.03.2020 12:15 18.182.144 llvm-lib.exe | 25.03.2020 12:00 18.182.144 llvm-ar.exe | | FC.exe "C:\Program Files\LLVM\bin\clang.exe" "C:\Program Files\LLVM\bin\clang-cl.exe" | Vergleichen der Dateien C:\PROGRAM FILES\LLVM\BIN\clang.exe und C:\PROGRAM FILES \LLVM\BIN\CLANG-CL.EXE | FC: Keine Unterschiede gefunden | | FSUTIL.exe Hardlink List "C:\Program Files\LLVM\bin\clang.exe" | \Program Files\LLVM\bin\clang.exe ...

Please ease up on the all-caps/shouting and sarcasm. It's not suitable in this forum. Yes, people on the project have likely heard of hard links. Perhaps there are practical reasons they're not suitable here, or someone hasn't had the time, etc - perhaps you could contribute patches/support for this? As for the x86/x64 - while clang itself is a cross compiler, yeah, I'm not sure any of the distributions include multiple target runtime support (though, yeah, being able to install them side-by-side, either as modules to the same installation, or at least both full installations separately) On Thu, Aug 20, 2020 at 11:49 AM Stefan Kanthak via llvm-dev <llvm-dev at lists.llvm.org> wrote:> > Hi @ll, > > BUGS #1 & #2: > ~~~~~~~~~~~~~ > > The installer LLVM-10.0.0-win64.exe dumps the following DUPLICATE files > in "C:\Program Files\LLVM\bin", WASTING about 500MB disk space, which is > nearly a third of the disk space occupied by the whole package: > > | DIR "C:\Program Files\LLVM\bin" /O:-S > ... > | 25.03.2020 12:15 83.258.880 clang-cl.exe > | 25.03.2020 12:03 83.258.880 clang.exe > | 25.03.2020 12:15 83.258.880 clang++.exe > | 25.03.2020 12:15 83.258.880 clang-cpp.exe > ... > | 25.03.2020 12:15 57.812.480 lld-link.exe > | 25.03.2020 12:05 57.812.480 lld.exe > | 25.03.2020 12:15 57.812.480 ld.lld.exe > | 25.03.2020 12:15 57.812.480 ld64.lld.exe > | 25.03.2020 12:15 57.812.480 wasm-ld.exe > ... > | 25.03.2020 12:15 18.182.144 llvm-ranlib.exe > | 25.03.2020 12:15 18.182.144 llvm-lib.exe > | 25.03.2020 12:00 18.182.144 llvm-ar.exe > | > | FC.exe "C:\Program Files\LLVM\bin\clang.exe" "C:\Program Files\LLVM\bin\clang-cl.exe" > | Vergleichen der Dateien C:\PROGRAM FILES\LLVM\BIN\clang.exe und C:\PROGRAM FILES > \LLVM\BIN\CLANG-CL.EXE > | FC: Keine Unterschiede gefunden > | > | FSUTIL.exe Hardlink List "C:\Program Files\LLVM\bin\clang.exe" > | \Program Files\LLVM\bin\clang.exe > ... > > > Dito for LLVM-10.0.0-win32.exe: > > | DIR "C:\Program Files (x86)\LLVM\bin" /O:-S > ... > | 25.03.2020 11:21 77.862.912 clang-cpp.exe > | 25.03.2020 11:21 77.862.912 clang-cl.exe > | 25.03.2020 11:21 77.862.912 clang++.exe > | 25.03.2020 11:13 77.862.912 clang.exe > ... > | 25.03.2020 11:22 54.811.648 ld.lld.exe > | 25.03.2020 11:22 54.811.648 ld64.lld.exe > | 25.03.2020 11:15 54.811.648 lld.exe > | 25.03.2020 11:22 54.811.648 lld-link.exe > | 25.03.2020 11:22 54.811.648 wasm-ld.exe > ... > | 25.03.2020 11:21 17.346.560 llvm-ranlib.exe > | 25.03.2020 11:10 17.346.560 llvm-ar.exe > | 25.03.2020 11:21 17.346.560 llvm-lib.exe > > Ever heard of hardlinks? > NTFS supports them since its introduction nearly 30 years ago, and > Windows NT provides an API to create them since 24 years. > > > BUGS #3 & #4: > ~~~~~~~~~~~~~ > > Although the compiler/linker/... installed with both packages are able > to produce 32-bit as well as 64-bit executables, 32-bit executables > can't be linked with the 64-bit package, and vice versa: each package > contains only the clang_rt.*.lib for its own architecture. > > The libraries for 32-bit targets are missing in LLVM-10.0.0-win64.exe, > and vice versa. > > | DIR "C:\Program Files\LLVM\lib\clang\10.0.0\lib\windows\*-i386.lib" > ... > | Datei nicht gefunden > ... > | DIR "C:\Program Files (x86)\LLVM\lib\clang\10.0.0\lib\windows\*-x86_64.lib" > ... > | Datei nicht gefunden > > > BUG #5: > ~~~~~~~ > > Poor souls who want to install the 64-bit package after/aside the > 32-bit package (or vice versa) are greeted with the following BOGUS > message from the installers: > ______________________________________________________ > | Installation von LLVM > |¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯ > | ^ > | /!\ LLVM is already installed. > | ¯¯¯ > | Do you want to install the old version before > | installing the new one? > | > | [ Ja ] [ Nein ] [ Abbrechen ] > | > ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯ > Also note the denglish kauderwelsch: the title bar and the buttons > are localized, but the message text isn't. > > > NOT AMUSED > Stefan Kanthak > > _______________________________________________ > LLVM Developers mailing list > llvm-dev at lists.llvm.org > https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-dev

I think David is not referring to the capitalization of file names, but to "DUPLICATE", "WASTING", "NOT AMUSED", "BOGUS" etc. It should be possible to report problems in a professional manner.

LLVM itself does not do any localization itself. I'd be more concerned that if offers to "install the old version" (rather than uninstall it). My guess this warning is a functionality provided by the Nullsoft Install System that assumes that software only needs to be installed once on the system. I wouldn't call it bogus, you may indeed not want to keep an older version installed at the same time. Michael -------------- next part -------------- An HTML attachment was scrubbed...

I'd rather be concerned about the OLD version here, which might be ANY other version, older, newer, or the same, but just for the other processor architecture of the target OS!

BUG #8: ~~~~~~~ The defective installer creates a shortcut "Uninstall LLVM" in the start menu, violating the MINIMUM requirements of the now 25 year old "Designed for Windows guidelines". JFTR: Windows ships with two builtin installers (SetupAPI and Windows Installer), there's no need to use a defective 3rd party product at all. Stefan

The Windows installer is provided best-effort by some people to reduce the barrier of entrace for Windows users. It is certainly not paid work. Your patronizing tone is not going to make anyone work on improving things. You don't provide any fixes either. At best, your mails are going to get ignored by those interested in the installer, if don't just come to taking the conclusion that the effort is not appreciated and going to remove them in first place. I would really suggest you to take a class on how to provide positive feedback. Otherwise, I would kindly request that you just leave behind this community and don't come back. The interactions with your mails have so far been far more harmful than any value they provided. Please don't bother with a reply. Not amused, Joerg
