Impossible to build libiptcdata, following the malfunction of msys2

[Desmis]

Yesterday I decided to update Msys2 (I do it about every 15 days) As my computer is protected from viruses by Avast, I disabled Avast for 1 hour I begin the update by $ pacman -Syu But just after startup, and before you say yes, I had a mishap of more than an hour, and when I came back to my computer to launch pacman, the antivirus probably reactivated and I forgot that And when Avast found "gpg-agent.exe", he considered it a virus, quarantined, without asking my opinion, and immediatly the system crash When I reboot, impossible to launch Msys2 or Mingw64

I tried, tried, but finally I decided to uninstall MSys2 and re-install How I do, step by step 1) uninstall Msys2 2) clean register 3) reboot system 4) install Msys2 5) immediately after, I used the lines of Rawpedia for Windows 64 bits $ pacman -S tar gzip nano make diffutils intltool git $ pacman -S mingw-w64-x86_64-gcc mingw-w64-x86_64-gdb mingw-w64-x86_64-make mingw-w64-x86_64-pkg-config mingw-w64-x86_64-cmake pacman -S mingw-w64-x86_64-gtkmm mingw-w64-x86_64-gtkmm3 mingw-w64-x86_64-lcms2 mingw-w64-x86_64-fftw mingw-w64-x86_64-lensfun

At this stage mingw-w64-x86_64-libjpeg-turbo mingw-w64-x86_64-lensfun mingw-w64-x86_64-gtk3 mingw-w64-x86_64-gtkmm3 are compatible "version"

Then I want to build libiptcdata, I strictly followed the instructions $ curl -LO http://downloads.sourceforge.net/project/libiptcdata/libiptcdata/1.0.4/libiptcdata-1.0.4.tar.gz $ tar xzf libiptcdata-1.0.4.tar.gz $ cd libiptcdata-1.0.4 Then $ ./configure --prefix=/mingw64

And I have this message jacques@pc-bureau MSYS ~ 4/libiptcdata-1.0.4.tar.gzs.sourceforge.net/project/libiptcdata/libiptcdata/1.0.4 % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 383 100 383 0 0 666 0 --:--:-- --:--:-- --:--:-- 666 100 555k 100 555k 0 0 134k 0 0:00:04 0:00:04 --:--:-- 251k

Invalid configuration x86_64-pc-msys': systemmsys' not recognized configure: error: /bin/sh ./config.sub x86_64-pc-msys failed

libiptcdata is not installed...

To continue, I modify pacman.conf with IgnorePkg = mingw-w64-x86_64-libjpeg-turbo IgnorePkg = mingw-w64-x86_64-lensfun IgnorePkg = mingw-w64-x86_64-gtk3 IgnorePkg = mingw-w64-x86_64-gtkmm3

Then $ pacman -Syu All libraries are update excepted those above

I re-tried to buils libiptcdata, same message What's is wrong ? what I missed ? Thank you for help me

@Desmis I found an issue elsewhere that seems similar to yours: https://github.com/JuliaLang/julia/issues/6234

Just to check: do you start mingw64.exe or msys2.exe? You should use the former, not the latter, when doing every step you described above.

[Thanatomanic]

Also, can you whitelist entire directories in Avast? It might help you with complications in the future.

@Thanatomanic

I used msys2...and if I read "Rawpedia", It's write, but for me not visible enough, because a) lost in the text b) it's write "MinGW-w64 Win32 Shell" instead of "mingw64" I think a slight modification of Rawpedia, would be welcome, to prevent this

I just try with launch with mingw64, and now libiptcdata is build I re-compile, all seems to work fine

Thank you very very much Jacques

@Desmis I agree that the Windows page is a little unclear. I'll put it on my todo list :smiley:

@Thanatomanic

thank you :)

@Thanatomanic @Desmis I wrote an completely updated rawpedia windows page in http://rawpedia.rawtherapee.com/User:Gaaned92 Could you review it before I copy back my user page in the window page?

@gaaned92 it seems clearer to me. Remark :

• In my reinstallation of Msys2 , I have tried with a) first , update of Msys2 by $ pacman -Syu, just after installation In this case, all package are uptodate and needs have to be downgraded, This morning I did not how to do, where are the "old" package (you bring a response), and my system does not work correctly (I cannot found "old" packages)

b) second, just after run Msys2 installation, whitout executing Pacman -Syu I install all tools, (miscellenaous, developpement, libraries, etc.),
Then changing git with "Ignorepkg" Then running Msys2 with Pacaman -Syu and all is good.. jacques
