Compiling with MSYS2

mgondan1 · May 10, 2021, 10:40am

Dear list, dear Jan,

I tried to compile SWI-Prolog with MSYS2 on Windows (to be more precise, MinGW64 by MSYS2). The process hangs during cmake, complaining that zlib*.dll is not found. It’s strange, since it is there:

Matthias@DESKTOP-A2T8IFC MINGW64 ~/swipl-devel/build
$ ls /bin/zlib1.dll
/bin/zlib1.dll

Matthias@DESKTOP-A2T8IFC MINGW64 ~/swipl-devel/build
$ rm -rf *

Matthias@DESKTOP-A2T8IFC MINGW64 ~/swipl-devel/build
$ cmake -G "MSYS Makefiles" ..
-- The C compiler identification is GNU 10.2.0

The use case will actually be RTools, the compiler environment for the R system, so that R packages can connect to swipl.

Best wishes,

Matthias

Its clear what is going wrong (can’t find zlib*.dll). I have little clue why though. I understood building the core has worked for some people on Windows. All I can advice is to put some additional message() calls in e.g. function find_file_from_pattern in Windows.cmake. Note that typically just running cmake .. is enough to test with the changes.

I guess it is no option for R, but building from source is a nightmare on Windows due to the large number of dependencies. That is why there is GitHub - SWI-Prolog/docker-swipl-build-mingw: Docker to cross-compile SWI-Prolog for Windows

mgondan1 · May 10, 2021, 5:55pm

MINGW_ROOT does not seem to be defined under MSYS2/MinGW64. Hence, this:

cmake -DMINGW_ROOT=/mingw64 -DINSTALL_DOCUMENTATION=OFF -DCMAKE_INSTALL_PREFIX:PATH=/usr/local -G “MSYS Makefiles” …

I had to do three more things to make „make“ work, as well as „make install“.

Some problem occurred during „make“ with pldoc (see the -DINSTALL_DOCUMENTATION=OFF). Not so important.
Error message during xpce (so I removed the folder packages/xpce). Not so important either.
I added -DCMAKE_INSTALL_PREFIX:PATH=/usr/local so that swipl is not installed into „C:\Program Files\swipl“ and so on.
And there’s no prompt , see below. [If you type “start swipl” instead of just swipl, the prompt is there]

Thank you! Great system, and no nightmare (anymore).

Best wishes,

Matthias

OK, here’s the MSYS2 installation:

@Jan, please consider removing the description from the webpage (with mingw under windows)

https://www.swi-prolog.org/build/MinGW.txt

Since this is now really outdated.

jan · May 16, 2021, 3:59pm

Why not update? Before doing so, how complete is the resulting system? I don’t see any of the dependencies mentioned except for libjpeg mingw-w64-x86_64-xpm-nox, both of which are needed for building xpce, but that is omitted from the build. What do you get from

?- check_installation.

mgondan1 · May 17, 2021, 7:36pm

I added a few packages and compiler switches, four issues left. And I agree, it is still a nightmare with the dependencies.

Thanks. No real clue about why debug should make a difference wrt loading libarchive!? Updated the page, copying the above and referring to this post. Note that you can propose changes to the static pages of the website using PRs on GitHub - SWI-Prolog/plweb-www: Submodule of plweb.git that contains the (wiki) web-pages

mgondan1 · June 11, 2021, 1:10pm

Did the same with MSYS2/mingw32: works fine, no changes except for i686 in the pacman package names instead of x86_64.

mgondan1 · June 19, 2021, 5:43pm

Ok, I found the problem with libarchive, the dlls for the different compression formats were not found. If I copy them into the installation folder /usr/local/bin, check_installation works.

cd /usr/local/bin
cp `ldd libarchive-13.dll |grep -o "/mingw64/bin/.*\\.dll"` .

If someone knows a better way to fix this problem, please let me know.
check_installation complains about 3 more issues, these are related to tcmalloc, xpce, java—none of them are found on a msys2/mingw64 system, so this is expected behavior.

Notes:

For those following the instructions (ref) be aware that Microsoft Defender or any antivirus software might be slowing down the process considerably. For more details see this.

Think of MSYS2 as a Bash shell that runs on Windows.

An easy way to start MSYS2 is

Click on the Windows search icon
Enter MSYS2
Select MSYS2 MinGW x64

which should start up a Bash shell.

For

ftp: download libuuid-1.6.2.tar.gz from ftp (dot) ossp (dot) org/pkg/lib/uuid/

use

$ wget -r --no-passive ftp://ftp.ossp.org/pkg/lib/uuid/uuid-1.6.2.tar.gz

Windows did prompt with a firewall request which I granted.

Dear Eric,

this description here is a bit outdated. msys2 actually has now a package swi-prolog that you can normally install with the pacman. It is 8.4.2, and a new version 8.4.3 is currently under review.

Please do also note that swipl-win.exe is not the “SWI-Prolog for Windows” that you normally use under windows. To me it seems to be just a white Window with a prolog prompt.

Best wishes,

Matthias

EricGT · August 2, 2022, 12:09pm

Now you tell me.

Actually building SWI-Prolog for Windows on Windows was a warm up task before trying to get the RocksDB pack, which has a build step (Makefile), to build on Windows using either pack_install/1,2 or pack_rebuild/0,1.

Thanks for the instructions I don’t think I could have built SWI-Prolog on Windows without them but as you note they do need some updating.

mgondan1 · August 10, 2022, 8:20am

All right. swipl-8.4.3 is now on msys2. Well, not msys2 in a strict sense, but on the mingw systems:

install msys2 from www.msys2.org
launch, e.g., the MSYS2 MinGW64 shell
then pacman -S mingw-w64-x86_64-swi-prolog

$ swipl
?- check_installation.
?- pack_install(environ).
?- environ(X).

A few patches were needed to make the Windows version compatible with MSYS2. Most importantly, the folder structure needs to be a bit more unix-like. You know, with the exes and dlls living in /mingw/lib/swipl/lib/swipl/lib/swipl/lib/swipl/lib/swipl/lib/amd64-windows/

I’ll see which ones are missing and propose the respective patches to be implemented in swipl-devel.

Enjoy! [not yet, the package is still in the “queue”, see here, Pending Package Updates - MSYS2 Packages]

mgondan1 · August 10, 2022, 12:05pm

Fast-forward to swipl-devel. I tried to compile under MSYS2 with “the usual steps”,

mkdir build
cd build
cmake -G Ninja -DSWIPL_PACKAGES_X=OFF -DINSTALL_DOCUMENTATION=OFF -DSWIPL_PACKAGES_JAVA=OFF -DCMAKE_INSTALL_PREFIX=/home/Matthias/swipl ..
ninja

Then, I get an error message for INDEX.pl (module not found, I think it is ssl4pl.dll). The error disappears if I run ninja again. Please see my experiments below. I think the problem is that creation of home/library/INDEX.pl actually depends on ssl4pl.dll, which is only build afterwards.

2nd ninja run:

removing ssl4pl is fine, it’s just being rebuild again:

Removing ssl4pl as well as INDEX produces the error (and please note that ssl4pl is build after INDEX):

I have seen that happening before. It is harmless but a bit ugly Must figure out the right dependencies some day …

If you could provide me a hint where to search for it, I am willing to try to fix it myself.
Support for cmake in Prolog packs was added in 8.5.2 already. I guess there was some use case for it. Do you remember the name of a “pack” that used cmake?

The stuff is defined (I think that is the right one) in cmake/LibIndex.cmake. There is a custom target library_index that has dependencies for the various packages. These dependencies should depend, possibly only on the target package, but possibly on all packages. Each package name is a named target (e.g., ssl, chr, etc.) Probably there is a variable with all packages, but I do not remember. The PackageSelection.cmake may tell you.

Too difficult for me. An interim solution is to let ninja build src/ssl4pl.dll first, then the rest

ninja src/ssl4pl.dll
ninja

It is not only ssl though. I’ve seen it with others as well, depending on how the concurrent build works out.
