Dear GNU Make developers,
I recently installed the newly released Bash 5.0 (accompanied by a new
libreadline library) in a user-specific directory. The host operating
system (on a server, where I don't have root access) uses an older
version of Bash.
Through Make's `SHELL' variable, I have asked Make to use the updated
version of Bash. In Make, I have also exported `LD_LIBRARY_PATH', so my
Bash can find the proper version of libreadline to link with. This
exportation of LD_LIBRARY_PATH is done very early in the Makefile and is
set with `:=':
export LD_LIBRARY_PATH := /home/user/.local/lib
This works nicely for all the shell calls within recipes. However, when
I use the $(shell ...) function, I get a linking error (shown below) by
my new Bash for every use of the $(shell ...) function.
/home/user/.local/bin/bash: error while loading shared libraries:
libreadline.so.8: cannot open shared object file: No such file or directory
Reverting back to the system's Bash, I tried $(shell printenv) as well
as a call to `printenv' in a recipe. I noticed that while the other
important environment variables like `PATH', `LDFLAGS' and etc are in
both, LD_LIBRARY_PATH is not present in value of $(shell printenv).
Since I couldn't find any mention of this in in the manual, I wanted to
see if this removal of LD_LIBRARY_PATH from the $(shell) function is
intentional or if its a bug?
I am using Make 4.2.90 (recently bootstrapped
https://git.savannah.gnu.org/cgit/make.git ).
Cheers,
Mohammad
