Description Philippe De Muyter 2017-09-29 09:33:30 UTC 
I try to compile valgrind-3.13.0.tar.bz2 on a opensuse 13.1 armv7hl platform,

using 'rpmbuild -bb valgrind.spec'

and that fails at :

gcc -DHAVE_CONFIG_H -I. -I..  -I.. -I../include -I../include -I../VEX/pub -I../VEX/pub -DVGA_arm=1 -DVGO_linux=1 -DVGP_arm_linux=1 -DVGPV_arm_linux_vanilla=1 -I../coregrind -DVG_LIBDIR="\"/usr/lib/valgrind"\" -DVG_PLATFORM="\"arm-linux\""  -O2 -g -std=gnu99 -Wall -Wmissing-prototypes -Wshadow -Wpointer-arith -Wstrict-prototypes -Wmissing-declarations -Wcast-qual -Wwrite-strings -Wempty-body -Wformat -Wformat-security -Wignored-qualifiers -Wmissing-parameter-type -Wold-style-declaration -fno-stack-protector -fno-strict-aliasing -fno-builtin  -marm -mcpu=cortex-a8 -DENABLE_LINUX_TICKET_LOCK -O2 -g -march=armv7-a -mfloat-abi=hard -mthumb -mabi=aapcs-linux -c -o libcoregrind_arm_linux_a-m_libcassert.o `test -f 'm_libcassert.c' || echo './'`m_libcassert.c

Comment 1 Julian Seward 2018-07-28 21:16:29 UTC 
I'd guess this is because rpmbuild somehow inserted -mthumb as a flag.
I'd furthermore guess that if you built it "by hand" without specifying
any extra flags, you'd get something that worked.
