How to repeat:
Compile from source, as shown in the build log.

Thank you for the report.

Could you please try sources available from our repository at  http://bazaar.launchpad.net/~mysql-proxy-developers/mysql-proxy/trunk/? Please also send us step-by-step instructions how you compile MySQL Proxy: I want to check if there is any difference with how we do it.

It appears that src/my_rdtsc.h is missing the typedef for ulong. That type is only used with GCC for SPARC, so we've never hit this bug before (we use SunStudio for compiling on Solaris, not sure we even have a build machine with Linux/SPARC).

Please try this patch:

Hi - I haven't had time to test this, but have cross linked to a Debian bug - 575246 - and asked the package team to try this. Thanks for the very fast response.

bzr trunk also fails to build.

The proposed patch doesn't help either. It enables src/my_rdtsc.c to be built but the definition causes a conflict later in the build.

I was able to get it to build on smetana.d.o (sparc porterbox) by adding #include <sys/types.h> to src/my_rdtsc.h. mysql-proxy upstream would probably want to add a check for that header to configure.ac and use the header when it is available.
