What I found until now is that the build failure is linked to the BR2_UCLIBC_INSTALL_UTILS option which builds and installs uclibc utilities such as getconf for the target. Build and install is done in UCLIBC_INSTALL_UTILS_TARGET (which is strange but I assume this is to avoid an UCLIBC_BUILD_UTILS_TARGET). Build failure is raised by Scrt1.o which is built during the previous step but I don't know why binutils complains about a missing -fPIC especially that is does complain only for microblaze :-/. > > > > So add a BR2_TOOLCHAIN_SUPPORTS_PIE dependency on BR2_PIC_PIE > > > > Fixes: > > - http://autobuild.buildroot.net/results/4cdd6f0368cc9d3c6e88f01b1a8929eb0839b638 > > - http://autobuild.buildroot.net/results/a82a484409149d7f9aff6140ddcb89f627f508c7 > > > > Signed-off-by: Fabrice Fontaine <fontaine.fabrice@gmail.com> > > --- > > Config.in | 9 +++++++++ > > 1 file changed, 9 insertions(+) > > > > diff --git a/Config.in b/Config.in > > index ebbb6b41f4..010b0774e3 100644 > > --- a/Config.in > > +++ b/Config.in > > @@ -697,10 +697,15 @@ comment "Security Hardening Options" > > config BR2_PIC_PIE > > bool "Build code with PIC/PIE" > > depends on BR2_SHARED_LIBS > > + depends on BR2_TOOLCHAIN_SUPPORTS_PIE > > help > > Generate Position-Independent Code (PIC) and link > > Position-Independent Executables (PIE). > > > > +comment "PIC/PIE needs a toolchain w/ PIE" > > + depends on BR2_SHARED_LIBS > > + depends on !BR2_TOOLCHAIN_SUPPORTS_PIE > > + > > choice > > bool "Stack Smashing Protection" > > default BR2_SSP_ALL if BR2_ENABLE_SSP # legacy > > @@ -783,12 +788,16 @@ config BR2_RELRO_PARTIAL > > > > config BR2_RELRO_FULL > > bool "Full" > > + depends on BR2_TOOLCHAIN_SUPPORTS_PIE > > select BR2_PIC_PIE > > help > > This option includes the partial configuration, but also marks > > the GOT as read-only at the cost of initialization time during > > program loading, i.e every time an executable is started. > > > > +comment "RELRO Full needs a toolchain w/ PIE" > > + depends on !BR2_TOOLCHAIN_SUPPORTS_PIE > > + > > endchoice > > > > comment "RELocation Read Only (RELRO) needs shared libraries" > > -- > > 2.23.0 > > > > _______________________________________________ > > buildroot mailing list > > buildroot@busybox.net > > http://lists.busybox.net/mailman/listinfo/buildroot > > > > -- > > Matthew Weber | Associate Director Software Engineer | Commercial Avionics > > COLLINS AEROSPACE > > 400 Collins Road NE, Cedar Rapids, Iowa 52498, USA > > Tel: +1 319 295 7349 | FAX: +1 319 263 6099 > > matthew.weber@collins.com | collinsaerospace.com > > > > CONFIDENTIALITY WARNING: This message may contain proprietary and/or > privileged information of Collins Aerospace and its affiliated > companies.
