You need to install the "-devel" version to get the it as a

Maybe on ubuntu it's this one:
"libgoogle-perftools-dev"
http://packages.ubuntu.com/fr/trusty/amd64/libgoogle-perftools-dev/filelist, because it
contains the "*.a" static library you wanna link in.
Works. Wonderful. Thanks.
BTW: Will this affect D's builtin GC or does it use mmap
directly?
It looks like if you manage to hook default malloc, free etc the
GC will be affected.
But a simple try to call the functions from the static lib fails
(the first script line is passed to DMD by my editor):
#!runnable flags: -L-ltcmalloc
extern(C) void* tc_malloc(size_t size);
extern(C) void tc_free(void* ptr);
void main(string[] args)
{
auto p = tc_malloc(16);
tc_free(p);
}

/tmp/temp_7FCC33C16DF0.d:(.text._Dmain+0x12): référence
indéfinie vers « tc_free »
interface seems to be this:
https://github.com/gperftools/gperftools/blob/master/src/gperftools/tcmalloc.h.in#L88
Do you have the interface or the D sources to call the functions ?
