Re: Fricas debian

Hi Waldek,

I've just looked into a .fasl file.

Do you know why in the installed version of such a file there appears
something like

#!/tmp/hemmecke/[more stuff]/bin/interpsys --script

as the first line?

Is a .fasl File a script? Or is this just coming from some bug in our
build system.

Note that the line is in the .fasl file in the install directory.
'interpsys' should be irrelevant anyway.

AFAIK this is feature of sbcl: you can make .fasl file executable
if you wish (and Lisp source were written in way so that it makes
sense).

OK, but these lines certainly make no sense in the installed system, the
build directory will be gone.

As I understand Alex (CC to him) building the debian package chokes on
these lines inthe sense that it produces lots of warnings like this

W: fricas: unusual-interpreter
usr/lib/x86_64-linux-gnu/fricas/target/x86_64-pc-linux-gnu/algebra/YSTREAM.fasl
#!/tmp/debian/fricas-1.3.5/build/x86_64-pc-linux-gnu/bin/interpsys

Alex, what is debuild actually checking so that these warnings appear?

Hi Qian,

That patch is obviously not enough.

Now there is

./src/interp/lisplib.fasl

without this hash-bang line, but for example

/src/aldor/lib/axlit.fasl

still shows

#!/tmp/hemmecke/target/x86_64-linux-gnu/bin/FRICASsys --script

and also in the intall directory appear the fasl files with

#!/tmp/hemmecke/x86_64-linux-gnu/bin/interpsys --script
