*** Bug 650866 has been marked as a duplicate of this bug. ***
I can confirm this. I was able to compile this version earlier this month, but not anymore. Not sure if it's relevant, but I changed my CFLAGS to "-O0 -march=i686 -pipe -ggdb".
Some further testing showed that when compiling innochecksum, the definition of the destructor is excluded (with an #ifndef UNIV_INNOCHECKSUM) while the declaration is still present. For some reason on my system with -O0 this leads to an undefined reference, while -O2 optimizes it away. However I see that Sven is using -O2. In any case, I think it should be solved by bringing #ifndef placement in ut0ut.h inline with #ifndef placement in ut0ut.cc.
Seeing the same error here. USE flags for dev-db/mariadb (from the build log): abi_x86_64 amd64 backup elibc_glibc extraengine kernel_linux pam perl server userland_GNU xml C Flags (also from the log file): -march=native -fno-strict-aliasing -pie -fPIC -Wl,-z,relro,-z,now -fstack-protector --param=ssp-buffer-size=4
(In reply to Maurice van der Pot from comment #4) > For some reason on my system with -O0 this leads to an undefined reference, > while -O2 optimizes it away. However I see that Sven is using -O2. I have to add, that I didn't use -O2 in my CFLags. Just forgot it to add, when I extracted the march=native flags. While it worked for several years, in the last months the number of failed packages have increased. And like you mentioned, the error passed away, when I added -O2 to my CFlags. So, it has to be decided, if the code should compile without a optimization flag too.
