On 28th December 2013, in a separate post,I reported this - > It seems I may have became a victim of a regression in gcc > http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58864 which helped me with this > statement - > > "it breaks with -march=i686 but works with -march=i586." > > I then noticed I hadn't set these flags - > > export LDFLAGS="" > export CXXFLAGS="-march=i486 -mtune=i486" > export CFLAGS="-march=i486 -mtune=i486" > > Once I'd set the flags the compile went through to a successful conclusion Well though the compile went through successfully I hadn't noticed that that my export of CFLAGS seems to have overwritten the autogen.sh generated CFLAGS. So I've managed to replace -O0 -gddb2 with -march=i486 -mtune=i486 I've fixed the problem, temporarily, by hacking config_host.mk diff config_host.mk.bak config_host.mk 77c77 < export CXX=/usr/bin/ccache g++ --- > export CXX=/usr/bin/ccache g++ -ggdb2 So my way forward is to decide which of the following options to go for <ul style="margin-top: 0px; margin-bottom: 0px; margin-right: 0px; -qt-list-indent: 1;"><li style=" margin-top:12px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">remove my externally set flags to see whether my original problem has gone away</li> <li style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">to see whether I can supply compiler flags external to autogen.sh without overiding the compiler flags generated by autogen .sh.</li> <li style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">I could go back to GCC version 4.7 series</li> <li style=" margin-top:0px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">try the latest from git as bug 58864 was fixed on 3rd December 2013.</li></ul> or maybe there's something I hadn't thought of? Though it does seem a bit bizarre that setting up CFLAG external to autogen.sh can overwrite the internally generated CFLAG, i'd have thought it should have concatenated the two - is this a bug?
