Vftrace could not find any parseable symbol tables associated with your executable
Closed this issue · 2 comments
I'm continuing to include Vftrace into my MPI project.
So far, I included Vftrace as Meson subproject (so, I do not have to explicitly care how to link (statically or dynamically) against Vftrace).
In the current setup, libvftraca.a is packed directly into my executable.
However, if I run my executable I get the message Vftrace could not find any parseable symbol tables associated with your executable.
Any suggestions?
BTW, it would be also nice if you could provide any kind of testing infrastructure and/or example for correct application? Just to get a right feeling for a typical application.
I tracked through Vftrace to find the suspecting point, i.e. when setting up the symbol table and reading in the current memory map
55XX55XXX00-55XX55XXX000 r--p 00000000 00:1a 8165080 <XX>/build/test/benchmark/benchmark_1
55XX55XXX00-55XX55XXX000 r-xp 00003000 00:1a 8165080 <XX>/build/test/benchmark/benchmark_1
With __VMAP_OFFSET not defined, Vftrace expects the offset to be at 0, this is obviously not the case (for me).
As a fast fix, I've just added -D__VMAP_OFFSET as build option, then, it works as expected.
Btw the configuration test using config_test.sh, which is not part of the repository, does not work then properly...
You were right about the VMAP_OFFSET. The config_test.sh script needs to be restored. I will close this issue and open a new one about that.
