Package: python3-distutils Version: 3.9.12-1 Severity: important Hello,
When trying to build matplotlib (that uses hardening +pie) on x32, -specs=/usr/share/dpkg/pie-compile.specs ends up being added to the flags passed to the linker. This breaks the build with: x86_64-linux-gnux32-g++ -pthread -shared -Wl,-O1 -Wl,-Bsymbolic-functions -specs=/usr/share/dpkg/pie-link.specs -Wl,-z,relro -Wl,-z,now -g -O2 -ffile-prefix-map=/tmp/matplotlib-3.5.1=. -specs=/usr/share/dpkg/pie-compile.specs -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2 build/temp.linux-x86_64-3.9/matplotlib.backends._backend_agg/extern/agg24-svn/src/agg_bezier_arc.o build/temp.linux-x86_64-3.9/matplotlib.backends._backend_agg/extern/agg24-svn/src/agg_curves.o build/temp.linux-x86_64-3.9/matplotlib.backends._backend_agg/extern/agg24-svn/src/agg_image_filters.o build/temp.linux-x86_64-3.9/matplotlib.backends._backend_agg/extern/agg24-svn/src/agg_trans_affine.o build/temp.linux-x86_64-3.9/matplotlib.backends._backend_agg/extern/agg24-svn/src/agg_vcgen_contour.o build/temp.linux-x86_64-3.9/matplotlib.backends._backend_agg/extern/agg24-svn/src/agg_vcgen_dash.o build/temp.linux-x86_64-3.9/matplotlib.backends._backend_agg/extern/agg24-svn/src/agg_vcgen_stroke.o build/temp.linux-x86_64-3.9/matplotlib.backends._backend_agg/extern/agg24-svn/src/agg_vpgen_segmentator.o build/temp.linux-x86_64-3.9/matplotlib.backends._backend_agg/src/_backend_agg.o build/temp.linux-x86_64-3.9/matplotlib.backends._backend_agg/src/_backend_agg_wrapper.o build/temp.linux-x86_64-3.9/matplotlib.backends._backend_agg/src/checkdep_freetype2.o build/temp.linux-x86_64-3.9/matplotlib.backends._backend_agg/src/py_converters.o -o build/lib.linux-x86_64-3.9/matplotlib/backends/_backend_agg.cpython-39-x86_64-linux-gnux32.so -lfreetype /usr/bin/ld: /tmp/cc7JfqHN.ltrans3.ltrans.o: warning: relocation against `PyExc_ValueError' in read-only section `.text' /usr/bin/ld: /tmp/cc7JfqHN.ltrans0.ltrans.o: relocation R_X86_64_PC32 against undefined symbol `_Py_NoneStruct' can not be used when making a shared object; recompile with -fPIC /usr/bin/ld: final link failed: bad value collect2: error: ld returned 1 exit status Looking in distutils code (/usr/lib/python3.9/distutils/sysconfig.py) it seems that the CFLAGS and CPPFLAGS are leaking in the flags passed to the linkers (LDFLAGS/LDSHARED) Is that expected?
