asymptote-2.49

[ken@…]

Mentioned on the tlbuild list, but many people there are unable to build it (e.g. needs c++ 2011, other problems on OSX) - waiting to see if any changes result.

No obvious changelog, the Changes file just shows the titles of git commits (mostly mswindows fixes, on a quick look).

Now 2.49 with portability and other fixes.

Found why my build of 2.49 was severeley broken, dependencies seem to have changed (but there are a lot of alternatives for different systems).

2.47 :

checking fftw3.h usability... yes
checking fftw3.h presence... yes
checking for fftw3.h... yes

2.49 :

configure: *** Could not find libGLEW: will compile without OpenGL support ***

Gets past that with glew installed, but my 3D tests still fail.

Tried adding --enable-offscreen (which pulls in osmesa, I think that is now only tested for with this option). The only docs I could find suggested this might merely allow rendering without using an X display. Configure then needed glm/glm.hpp which comes from glm (C++ headers for GL maths, or something like that).

After working around a hardware problem (turned out to be a broken PS/2 keyboard!) I've now built that, and run a quick test of one of the 3D files in my asy testsuite (to png, workedf window frame on the X display was visible while it ran).

Now I need to confirm whether --enable-offscreen is essential (it is marked as experimental), or whether adding glm was all that was required.

[ken@…]

Adding glm was indeed all that was required, so this version of asymptote will require both glew and glm to be added to the book.

But there were other issues in my "pure asy" tests (i.e. using it outside of TeX). My radeon driver ran out of memory on the fully-rendered ('16') versions of my torus test in both the eps and pdf forms, although the png form was ok. And then I discovered that my recent build of evince can no-longer display eps files (probably, the ghostscript hardening in the past year). For the PDFs I've added smaller '8' and '12' versions. I also reworked the package to ONLY include the two interesting drawings (kleinbottle, torus), and to move the created output to example- directories. If anybody cares, updated version at ​http://www.linuxfromscratch.org/~ken/misc-testfiles/asy-test-20190409.tar.xz

Fixed, I think, in r21444.
