Cannot build asymptote 2.87 with mesa 24.0.2

[thegreyshadow]

Using Slackware-current. Mesa version is 24.0.2.

Building of asymptote-2.87 fails with the following output:

Thanks for asymptote, and please consider fixing this.

Try ./configure --disable-offscreen. Offscreen rendering is for headless servers only (no GPU card).

[johncbowman]

It looks like your osmesa.h header isn't setting GLAPI and GLAPIENTRY correctly; if you really want offscreen rendering (which disables interactive onscreen 3D rendering) I suggest you get a simple example working with OSMesa first.

Try ./configure --disable-offscreen. Offscreen rendering is for headless servers only (no GPU card).

Indeed. Asymptote built fine passing that parameter. Thanks!

In commit https://gitlab.freedesktop.org/mesa/mesa/-/commit/5bf68ab70133edd264f832f4a133288b8b45f66d GLAPIENTRY was changed to APIENTRY.
