Cannot source /etc/profile from within the PKGBUILD anymore

Question

Hi,
Short story: the command
source /etc/profile
within the build() section of my PKGBUILD now returns a build() error. It used to work before, is there a reason for this? Should it be executed in another section than build()? (Note source /etc/profile works properly in console, within the build directory)
Long story:
I need to use $JAVA_HOME in my PKGBUILD (to patch a lua source file with the current JDK path, which can be detected with $JAVA_HOME. Patching is done with a sed command). However, if java-environment is installed for the first time (as a makedepends) along with my package, then I need to source /etc/profile first to set the $JAVA_HOME environment variable, before being able to use it within my build() section. Otherwise it is not set yet and building fails.
Many thanks for your help.

Answer 1

Hi,
Many thanks for the advice. I was unclear though: I maintain the aacskeys package in AUR, not the lua package. However, the file I am patching in aacskeys is named premake.lua, used for the project file generator premake.sourceforge.net.
I'll try your first suggestion, since this is the only one which may work without touching the system. Another alternative would be to directly source the /etc/profile.d/jdk.sh file. EDIT: nope, because there could be openjdk6.sh instead. I really need to be able to source the correct file. The maintainer of opencascade uses:
if [ -z $JAVA_HOME ]; then
[ -e /etc/profile.d/openjdk6.sh ] && source /etc/profile.d/openjdk6.sh
[ -e /etc/profile.d/jdk.sh ] && source /etc/profile.d/jdk.sh
fi
which is efficacious but less generic.
Besides, is it normal that we get this error code, since the Arch documentation only recommends to set LANG in /etc/locale.conf? SHould I report it as a bug or request a design change for /etc/profile.d/locale.sh there (as suggested in your (b) entry)? I am asking this because my PKGBUILD is not the only one to use this trick, and this problem breaks them all.
Thanks.
