Linking tcmalloc and unwind

[chrizpower]

Hi there,

I noticed I wasn't compiling my node with -DTARAXA_GPERF=ON. Changed that now. To make it compile, I needed to install libunwind-dev and add unwind to core_libs

if(TCMALLOC_LIB)
    target_link_libraries(core_libs INTERFACE ${TCMALLOC_LIB} unwind) # MUST BE LINKED LAST!!!
endif()

I'm on Debian 13. Currently, I maintain a patch, but was wondering if anyone else encountered this and obviously I would rather like to ditch my patch if there is a better solution.

I addressed this by switching to tcmalloc_minimal. Doesn't link against unwind so problem gone. I'm linking statically btw. I assume dynamic linking might not have this issue to start with. I'm not sure what the intention of TARAXA_GPERF is, but if it is mainly about performance I think it would be better to switch to tcmalloc_minimal (simply swap this with tcmalloc in the main CMakeLists.txt). The non-minimal version has heap checking and profiling which have to be turned on and seems to be rather helpful for development etc.
