Hello,
I have defined an alias for eshell, which is found
in .emacs/eshell/alias :
alias PC17 g++ -Wall -std=c++17 -pthread $1
This works fine to compile files, such as:
PC17 explicit.cc
Although it does not work when an extra compile parameter is added,
such as:
PC17 -DEXPLICIT explicit.cc
g++: fatal error: no input files
It looks like $1 does not stand for any number of arguments, taking one
and rejecting any others.
At the regular Linux console, the just-about same (w/o the $1) alias
works with extra params:
alias PC17='g++ -Wall -std=c++17 -pthread
% PC17 -DEXPLICIT explicit.cc
Is there a way to add on-the-spot parameters in eshell w/o having to
modify the eshell alias itself ?
Cheers.

Try $* rather than $1, as in
alias PC17 g++ -Wall -std=c++17 -pthread $*
Best wishes,
