[Debian-med-packaging] Seeking CMake help for spades

[Sascha Steinbiss]

Hi all,

I’m trying to make spades use Debian’s jemalloc, but CMake looks fairly magic to me and I suspect that for someone experienced that’s just a one-liner…
I tried the attached patch but it didn’t help:

[ 73%] Building CXX object io/CMakeFiles/input.dir/logger_impl.cpp.o
/build/spades-3.6.2+dfsg/src/io/logger_impl.cpp: In member function 'void logging::logger::log(logging::level, const char*, size_t, const char*, const char*)':
/build/spades-3.6.2+dfsg/src/io/logger_impl.cpp:107:51: error: 'je_mallctl' was not declared in this scope
   je_mallctl("stats.cactive", &cmem, &clen, NULL, 0);
                                                   ^
io/CMakeFiles/input.dir/build.make:158: recipe for target 'io/CMakeFiles/input.dir/logger_impl.cpp.o' failed
make[4]: *** [io/CMakeFiles/input.dir/logger_impl.cpp.o] Error 1

Any advice is welcome…

Cheers
Sascha
