Dear list,

Today I tried to build swipl on a fresh MSYS2 installation for Win64. I got quite far actually:

The usual pacman stuff

- pacman -Syu, then pacman -Su git, cmake, gcc, make, zlib-devel, ncurses-devel, gmp-devel, libedit-devel, openssl-devel, libarchive-devel, base-devel, libcrypt-devel

Then

- cd swipl-devel
- mkdir build
- cmake …
- make
- make install
- swipl

During compilation, an error message appeared, stating that ftello64, fseek64 etc. were not found. I made a little change around line 20 in src/minizip/ioapi.c

`#if defined( __APPLE__ ) || defined(IOAPI_NO_64)`

to

`#if defined( __APPLE__ ) || defined(IOAPI_NO_64) || (defined( __MSYS__ ) && defined(__x86_64))`

This made the compilation work, but I am very unsure if it is correct - it would obviously be better to have IOAPI\_NO\_64 set properly, whatever this is. The compilation reached 100%, although there were two blocks of red error messages, some issues with shared libraries that couldn’t be loaded.

```prolog
ERROR: /home/Matthias/swipl-devel/build/home/library/archive.pl:96:
ERROR: /home/Matthias/swipl-devel/build/home/library/archive.pl:96: Initialization goal raised exception:

ERROR: /home/Matthias/swipl-devel/build/home/library/prolog_pack.pl:726:
ERROR: Exported procedure archive:archive_set_header_property/2 is not defined

```

And a second one related to http

```prolog
ERROR: /home/Matthias/swipl-devel/build/home/library/crypto.pl:72:
ERROR: /home/Matthias/swipl-devel/build/home/library/crypto.pl:72: Initialization goal raised exception:

ERROR: /home/Matthias/swipl-devel/build/home/library/ssl.pl:67:
ERROR: Exported procedure crypto:rsa_private_decrypt/4 is not defined
(I skipped the rest)

```

After make install, I had to copy msys-swipl-8.dll to a folder where it could be found by the system.

So, there seem to be only minor issues with finding dlls, and the thing with the 64-bit fseek.

Best wishes,

Matthias

Thanks. Pushed a patch that uses CMake to figure out whether or not to use the 64 bit file functions. Note that it doesn’t matter much. We only use this stuff to read the Prolog startup file.

The reported errors are dependency issues that cause some of the documentation to be built too soon. It is harmless (but I’m still hoping it is fixable). In fact, I thought I’d fixed it. Did you use the release tar or git?

What is `msys-swipl-8.dll`? Is that a dedicated runtime library or so?

Dear Jan, I used the current git, and now I updated for a test:

- 64 bit file functions: works fine now.
- the errors while building the documentation are still there: I have put the filename into the PL\_error call (pl-load.c, line 226 -\> return PL\_error(NULL, 0, _ **fn** _, ERR\_SHARED\_OBJ\_OP, [etc]))

```prolog
ERROR: /home/Matthias/swipl-devel/build/home/library/crypto.pl:72:
ERROR: /home/Matthias/swipl-devel/build/home/library/crypto.pl:72: Initialization goal raised exception:

ERROR: Exported procedure crypto:rsa_private_decrypt/4 is not defined
ERROR: /home/Matthias/swipl-devel/build/home/library/ssl.pl:67:

```

Same issue for ssl4pl and (a bit earlier) archive4pl. As you mention, they are harmless during the build process, so everything continues until 100%.

- make install: the msys-swipl-8.dll is probably the same as libswipl-8.1.28.so in linux (?)
- Invoking swipl works.
- Then I wanted to install a pack: pack\_install(rserve\_client)

```

Connectivity with R is actually the main motivation behind this exercise. Thank you for consideration. It is very much appreciated, given that the build process under windows is not among the top priorities of the project, as far as I know.

With best wishes,

Matthias

Dear Jan,

After today’s git pull in MSYS2 (Win64): The error messages related to crypto4pl and ssl4pl have disappeared. FWIW: The error related to archive4pl is still there. This is the screen dump of my “make” under MSYS2. Please note that I have put a little line in PL\_dlopen that prints the file name of the shared library that is to be loaded, therefore, the extra lines in the output. You can see that the path for archive2pl is not being expanded:

```prolog

```

Best regards, and, as always, thanks for this great software.

Thanks for testing. I now know how to get rid of these, so I pushed a fix. Although harmless, a clean build looks so much better 🙂

The lack of expansion is because Prolog cannot find the dll. It first tries to find the dll and loads it using an absolute path, so it knows it has the right one. If that fails it tries the plain dll name, hoping the OS can find it.

Works. Thanks!
