Description Agostino Sarubbo gentoo-dev 2020-06-04 10:28:11 UTC
This is an auto-filed bug because app-emulation/qemu does not respect LDFLAGS.
The issue was originally discovered on amd64, but it may be reproducible on other arches as well.
If you think that a different summary clarifies the issue better, feel free to change it.
Attached build log and emerge --info.

NOTE:
To reproduce this issue you may want to set LDFLAGS="${LDFLAGS} -Wl,--defsym=__gentoo_check_ldflags__=0". If this is not something about c/c++ context you may want to see this bug as an hint to hide the QA warning (with QA_FLAGS_IGNORED) where is not possible to respect LDFLAGS.

Comment 2 Sergei Trofimovich gentoo-dev 2020-06-04 18:20:18 UTC
The relevant build log snippet is:

"""
 * QA Notice: Files built without respecting LDFLAGS have been detected
 *  Please include the following list of files in your report:
 * /usr/bin/elf2dmp
 * /usr/bin/ivshmem-client

"""


Looking at a elf2dmp:

"""
x86_64-pc-linux-gnu-g++ -O2 -pipe -march=native -frecord-gcc-switches -Wl,--warn-common -Wl,-z,relro -Wl,-z,now -pie -m64  -fstack-protector-strong -o elf2dmp contrib/elf2dmp/main.o contrib/elf2dmp/addrspace.o contrib/elf2dmp/download.o contrib/elf2dmp/pdb.o contrib/elf2dmp/qemu_elf.o    -lcurl -lm -lz  -lgthread-2.0 -pthread -lglib-2.0   -lrt -lz -lutil -lcap-ng
"""

Original  flags areLDFLAGS="-Wl,-O1 -Wl,--as-needed -Wl,--defsym=__gentoo_check_ldflags__=0".

Looks like they were not passed at all.
