Hello, Yes, your suggestion to define MY_CONTEXT_USE_UCONTEXT when compiling a release build with gcc 4.7.1 worked. Interestingly, this patch was not required with gcc 4.7.1 debug build. BTW, there are a LOT of compiler warnings, one of which is:
sql/log.h:480:3: warning: access declarations are deprecated in favour of using-declarations; suggestion: add the ‘using’ keyword [-Wdeprecated] On Fri, Aug 3, 2012 at 2:08 PM, Michael Widenius <[email protected]> wrote: > > Hi! > >>>>>> "Rich" == Rich Prohaska <[email protected]> writes: > > Rich> hello, > Rich> we have been using gcc 4.4 to build mysql and mariadb successfully. > Rich> however, when we tried to use gcc 4.7.1 to build mariadb-5.5.25, we > Rich> hit this problem: > > Rich> > /home/tokubuild/build-tokudb-46462/mariadb-5.5.25-tokudb-46462-linux-x86_64-build/mariadb-5.5.25-tokudb-46462-src/mysys/my_context.c: > Rich> Assembler messages: > Rich> > /home/tokubuild/build-tokudb-46462/mariadb-5.5.25-tokudb-46462-linux-x86_64-build/mariadb-5.5.25-tokudb-46462-src/mysys/my_context.c:207: > Rich> Error: CFI instruction used without previous .cfi_startproc > > Rich> what compiler do you use to build mariadb? > > We are using a lot of different compilers on a lot of different > systems and compilers and on all tested ones, MariaDB compiles nicely. > > Don't know if we have gcc 4.7.1 on any system. > I am using latest Open-SuSE myself and that comes with gcc 4.6.2 > > It looks like issue is that the new gcc has a different asm syntax > than the old one :( > > Fix: > > Ensure that MY_CONTEXT_USE_UCONTEXT is defined when you compile > MariaDB.
