Subject: bug#24416: avr-gcc@5 is broken
Date: Mon, 12 Sep 2016 08:49:36 +0200 [thread overview]
Message-ID: <20160912084936.25713732@scratchpost.org> (raw)
In-Reply-To: <CAJ=RwfbF+75d=E+mZ-_nNoHnRYL7Uy8m=CsQRGTwLi6jDQ-b4w@mail.gmail.com>
As a workaround,
CPPFLAGS += -I${HOME}/.guix-profile/avr/include
LDFLAGS += -L${HOME}/.guix-profile/avr/lib/avr5 -L${HOME}/.guix-profile/avr/lib -B${HOME}/.guix-profile/avr/lib
works with avr-gcc 5.3.0. Unfortunately I don't know enough about avr-gcc to be able to permanently fix it.
I fixed part of it (I made it so that atmega32u4 exists in the first place) in master - but no idea what to do with the search path.
I'm pretty sure that if it uses CROSS_CPATH it's incorrect because cross-base has been changed from CROSS_CPATH to CROSS_C_INCLUDE_PATH, CROSS_CPLUS_INCLUDE_PATH etc in order to suppress warnings. If CROSS_C_INCLUDE_PATH overrides CROSS_CPATH (does it?) then setting CROSS_CPATH like avr.scm does does no good.
I propose to change it to the following:
diff --git a/gnu/packages/avr.scm b/gnu/packages/avr.scm
index 9873477..1e5fd73 100644
--- a/gnu/packages/avr.scm
+++ b/gnu/packages/avr.scm
