Source: llvm-toolchain-9 Version: 1:9.0.1-8 Severity: wishlist Hello,
A few package rebuilds with clang fail because since clang doesn't support Fortran yet, we have a mixture of .o files from clang and .o files from gfortran, and since gcc enables -fPIE by default, the eventual link with gfortran fails. This shows up for instance at the very beginning of the build of the opari2 package with clang: https://clang.debian.net/logs/2020-02-24-9.0.1/opari2_2.0.4-3_unstable_clang9.0.1.log gcc -DHAVE_CONFIG_H -I. -I./../src -I./../src -DFRONTEND_BUILD -DCROSS_BUILD -Wdate-time -D_FORTIFY_SOURCE=2 -g -O2 -fdebug-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong -Wformat -Werror=format-security -c -o foos.o `test -f '../src/opari-lib-dummy/foos.c' || echo './'`../src/opari-lib-dummy/foos.c gfortran -g -O2 -fdebug-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong -c -o getfname.o `test -f '../src/opari-lib-dummy/getfname.f' || echo './'`../src/opari-lib-dummy/getfname.f /bin/bash ./libtool --tag=F77 --mode=link gfortran -g -O2 -fdebug-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong -Wl,-z,relro -o getfname foos.o getfname.o libtool: link: gfortran -g -O2 -fdebug-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong -Wl,-z -Wl,relro -o getfname foos.o getfname.o /usr/bin/ld: foos.o: relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a PIE object; recompile with -fPIE where gcc is clang; gfortran is thus trying to link foos.o compiled by clang and getfname.o compiled by gfortran.
