File and Libmagic build with Visual Studio

This aims to have everything one needs to build file on windows with visual studio.

Checkout with submodules

git submodule update --init --recursiv

External Dependencies

• regex: I am using PCRE2 version 10.30. Unfortunately this is not available on github with tags, so I commited it in this repo. I copied pcre2posix.h to regex.h.
• dirent: Dirent is not available on windows, so I used a implementation from tronkko.
• getopt: A similar problem exists with getopt, so I used a implementation from skandhurkat.

Linking

• all the dependencies are statically linked or compiled into the dll
• There is a .def file in windows headers describing the exports for the linker
• Since dirent defines some of the symbols used in files readelf.c and magic.c the include is "patched" into them in the CMakeLists.txt

Updating file

• Checkout the version in the file submodule.
• Update CMakeLists.txt
• Update appveyor.yml

Updating pcre2

• I disabled the test in the CMakeFile.txt manually, the rest is vanilla.

file-windows's Issues

Please update file to 5.39

Hello Julian. Thank you for this project!

We depend on the bug fix https://bugs.astron.com/view.php?id=165 that is part of release 5.39. It is easy enough for us to update the git submodule and the other relevant files following the model of 589d0aa, but I was wondering if you would consider performing a 5.39 update. Thank you.

Error "file: (null) (No such file or directory)"

Any file type, same error

Unable to build using VS2010 in windows

I'm facing a lot of compiler issues when trying to build using cmake and visual studio 2010.

1. error C2061: syntax error : identifier 'mode_t' [C:\Krishna\File-Magic\file-windows\libmagic.vcxproj]
2. file\src\apprentice.c(457): error C2037: left of 'flags' specifies undefined struct/union 'magic_set' [C:\Krishna\File-Magic\file-windows\libmagic.vcxproj]

Looks like the VS compiler is not able to read the unix-style code. Is there any special compiler switch or something that is necessary to avoid these errors?

Thanks.

Wildcard/globbing functionality

This would be more useful if it could use wildcards. Could it be compiled using what is described here?

ARM build

Could you build this for ARM as well? This would be useful for Windows on my M1 Mac. I'm sure performance will never be an issue in the emulator, but it would still be nice.

How to build?

Can you write guide how to build file with cmake?
I'm trying to build it with "Visual Studio 15 2017", but no luck.

May I ask which version of Visual Studio this project is using?

not building 64bit DLL

Julien,
awesome effort.
any chance to get this building libmagic.DLL for x86_64?

thanks,

Joerg

Latest versions

Hi @julian-r!

I'm planning to upgrade the file package in Scoop package manager. Currently it's stuck on a very old GnuWin32 build - https://github.com/ScoopInstaller/Main/blob/master/bucket/file.json

I'd like to ask if there's any plan to release the latest version of file (5.41)?
