how to build mupdf static library in window platform about go-fitz

[guoquanlebytedance]

As a supplement, I am solving this problem #83. I can not get a mupdf static library.

[gen2brain]

All static libraries are cross compiled on Linux. Mingw toolchain for Windows and Osxcross for macOS. For me it is much easier to build everything in Linux, I don't even know how to build something in Windows.

[gen2brain]

I guess you can use WSL and install Mingw there, instead of using the VS.

[guoquanlebytedance]

May I ask how to cross-compile mupdf on linux, where files need to be changed?

This is the bash script I am using to build everything, hope it can help you.

[gen2brain]

Of course, I have a patch that disables CJK fonts, static library is by default 50M, and without CJK fonts is 5M.

[guoquanlebytedance]

Thank you very much.
I'll try this script.
And How can this patch be used?

[gen2brain]

If your goal is to build with CJK fonts, you don't need the patch, it just modifies Makefile/Makerules and some define in the header file. The default build should work for you.

[guoquanlebytedance]

I'm sorry I didn't understand what you mean, I'm directly referencing the latest go-fitz in go.mod now, but I still have CJK problems. Do you mean that the go-fitz default version can solve this problem, or do you mean that I just need to compile the default build of the mupdf static library.

[gen2brain]

It is not related to go-fitz. For CJK, all you need is extlib tag. That will use external library, whether it is dynamic/shared or static library is up to user. If you don't want a requirement that your users need to install mupdf, static library is a must.
