Re: Weird error when installing caps from AUR

I emailed the author of alsaequal.
He said "...maybe they have a way to temporarily point to Python 2 and then change it back"

can someone please help me figure this out? im pretty new on arch.

Re: Weird error when installing caps from AUR

According to the PKGBUILD, python is an optional dependency for this package, only required for a CFLAGS check. If you were to build the package in a clean chroot, the error would not occur, because python would not be installed. As you are presumably not doing that, you could remove python from your system, build the package, then reinstall python.

Or, if you want to do it the right way, change 'python' to 'python2' on line 20 of the PKGBUILD and use either sed or a patch to change the configure.py script to use python2.

Re: Weird error when installing caps from AUR

after the download open PKGBUILD and in the build section

add 2 or 2.7 after the word python.

type -p python 1>/dev/null && ./configure.py 

to

type -p python2 1>/dev/null && ./configure.py

or

type -p python2.7 1>/dev/null && ./configure.py

Re: Weird error when installing caps from AUR

Hello, I have exactly the same problem.
So I replaced
type -p python 1>/dev/null && ./configure.py 
by
type -p python2.7 1>/dev/null && ./configure.py

The compilation does not work and I have the following error message:

Re: Weird error when installing caps from AUR

i've just downloaded caps-0.4.4-2 from AUR and it compield with no error.

(with no change in the files)

maybe it because i changed the python symlink

to point to python2.7 instead of python3.

Re: Weird error when installing caps from AUR

Indeed, following an update of caps, it compiles perfectly.
There are no more error.

Thank you for your help.
