Re: Question: Cross compilation

[Chris Yate]

Hi Phil,

Sigh... Yes, that's basically the conclusion I'd already come to, but that it seemed such a ludicrous state of affairs that _somebody_ must have a better solution.  

I've just installed mingw on Ubuntu, which might possibly do the job...

At the moment my scores have a habit of crashing at line 1180 in page-breaking.cc when an assertion is thrown; that only happens under Windows. And I reckon I can now see why it hasn't been investigated seriously by anyone!! (although it's possible it could be an issue with one of Lilypond's library dependencies.).  

It should not be so difficult to work on open source stuff on any platform. And it's not Microsoft's fault, presumably a lack of demand... (I'm not blaming anybody here, by the way.)  In terms of the time I've wasted, I'm fairly seriously considering that I might buy Sibelius and be done with it. Given that most of my colleagues in music expect me to be able to send them .sib files to share, it's probably inevitable. Shame.

Gub uses http://git.savannah.gnu.org/cgit/lilypond.git as its source.  I know of no way of changing that without a lot of effort changing its codebase.  I personally know of no simple way of cross-compiling LilyPond for Windows without using Gub as the tool.  However, you can (in principle) create your own branch on Savannah and use Gub to compile against that (see http://git.savannah.gnu.org/cgit/lilypond.git/log/?h=dev/philh for an example of something I'm trying to debug at present).  You'll need a big old machine or a lot of patience to get it working - I occasionally have compile time of the order of 24 hours on a Core i7 quad core system.

Subject: Question: Cross compilation

Hi all,

Apologies for the potentially "blindingly obvious" question, bu't having read the devel webpages about compiling Lilypond for mingw/Windows, I'm none the wiser.

I can compile for native linux using the gnu make (via the smart-autoconf.sh script). However, I'm trying to track down a crash in Windows, and according to the website/docs it's impossible to compile natively* -- so need a cross-compile.

I note the existance of "GUB", but this appears to use the main repository as source**. But obviously, I need to compile from my working copy after I've put a bunch of tracing code in. 

This document http://www.gnu.org/software/lilypond/src/Developers/Packaging/windows.html appears to be out of date. I found "janneke"'s patches at http://lilypond.org/people/janneke/software/cygwin/mknetrel/ but it's not clear from where mknetrel itself should be obtained. 

My dev environment is Ubuntu 16 (or 14). Any hints or tips or redirection towards the relevant instructions would be welcome!

Chris

* assuming the statement about compiling natively under Windows _does_not_ refer to using mingw gnu make, rather than some other compiler...??

** I'm not sure about that; but in any case it fails at configuring mingw::fontconfig so that may be the first problem to solve. Error below

.....

configure: error: Package requirements (freetype2) were not met:

Package zlib was not found in the pkg-config search path.

Perhaps you should add the directory containing `zlib.pc'

to the PKG_CONFIG_PATH environment variable

Package 'zlib', required by 'FreeType 2', not found

....
