Bug ID: 64486
Summary: Failure building cross compiler for arm-eabi
(system.ads)
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: ada
Assignee: unassigned at gcc dot gnu.org
Reporter: simon at pushface dot org
Both GCC 4.9.1 and GNAT GPL 2014 fail to build a cross-compiler to arm-eabi
based on gcc-5-20141228.
gcc -c -g -O2 -gnatpg -gnata -W -Wall -nostdinc -I- -I. -Iada/generated -Iada
-I../../gcc-5-20141228/gcc/ada -I../../gcc-5-20141228/gcc/ada/gcc-interface
../../gcc-5-20141228/gcc/ada/system.ads -o ada/system.o
system.ads:53:11: warning: unrecognized pragma "No_Elaboration_Code_All"
make[2]: *** [ada/system.o] Error 1
The configuration command was
$ ../gcc-5-20141228/configure --build=x86_64-apple-darwin13 --target=arm-eabi
--prefix=/Users/simon/local-arm --with-stage1-libs=no --with-stage1-ldflags=no
--with-cpu=cortex-m4 --with-fpu=fpv4-sp-d16 --with-float=hard --with-mode=thumb
--enable-interwork --enable-multilib --enable-languages=c,c++,ada
--with-system-zlib --with-newlib --with-libgloss --disable-shared --disable-nls
--disable-libada --with-gnu-as --with-gnu-ld
--with-bugurl=URL:mailto:si...@pushface.org
I worked round by wrapping the offending line in pragma Warnings (Off), pragma
Warnings (On).
