you tried to reproduce it with Buildroot with this: ''' # git clone git://git.busybox.net/buildroot # wget https://git.busybox.net/buildroot-test/tree/utils/br-reproduce-build - modify BASE_GIT=... with your buildroot path in br-reproduce-build then: # chmod a+x br-reproduce-build # ./br-reproduce-build 3eb9f9d0f6d8274b2d19753c006bd83f7d536e3c ''' ? Other commands are needed to avoid rebuilding everything again and again. so after the ones above: # cd 9084cd777aefe0fa8235514c33767d8640ad7a5b # cd output # make V=1 libgeos This ^^^^ is to rebuilding even if it failed and passing V=1 evrything is verbose, so you can get exactly C/CXX/LDFLAGS. You can also find the sources of binutils under output/build/host-binutilsXX.X/ so there you can modify and then rebuild binutils with: # cd output # make host-binutils This ^^^ should rebuild modified sources and re-install the binaries under output/host/usr/bin that is were buildroot takes binutils binaries. I give you the exact FLAGS passed by Buildroot anyway: CXX_FLAGS = -DNDEBUG -fPIC -ffp-contract=off -std=c++11 LDFLAGS = -fPIC -DNDEBUG Hope this helps Best regards -- You are receiving this mail because: You are on the CC list for the bug.
