[Pkg-pascal-devel] need advice: unable to create package output directory "/usr/..."

[Yaroslav Halchenko]

Dear Pascal Gurus,

I am working with upstream trying to package mricrogl.
Packaging here https://salsa.debian.org/med-team/mricrogl

We (with me knowing not much about Pascal build system) followed
packaging of older mricron, and debian/rules contains

	# lazbuild really wants to modify some configs during initial lazbuild
	# so we will provide a fake HOME dir
	export HOME=$(CURDIR)/build


	# one ring to rule them all ...
	%:
		dh $@


	override_dh_auto_build:
		mkdir -p $(CURDIR)/build
		lazbuild --add-package lazopenglcontext
		lazbuild --build-all --ws=qt5 --pcp=/etc/lazarus MRIcroGL.lpi
		mv ./MRIcroGL mricrogl

and then during a proper sanitized build using cowbuilder in sid
(lcl-utils 2.0.12+dfsg-6) I get

	debian/rules override_dh_auto_build
	make[1]: Entering directory '/build/mricrogl-1.2.20211007+dfsg'
	mkdir -p /build/mricrogl-1.2.20211007+dfsg/build

	make[1]: Leaving directory '/build/mricrogl-1.2.20211007+dfsg'


so the first --add-package seems to be ok, but then subsequent
--build-all wants to change system-wide files.

Is there a better/proper way to fix this or it is some issue within lazbuild?
(searched up some older
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=906349 which might
relate)

thanks in advance and please keep me in CC (not subscribed to the list).
