I am trying to profile a Lazarus application with valgrind, callgind and kcachegrind using for instance
valgrind --tool=callgrind --dump-instr=yes --collect-jumps=yes ./matrixtest
and kcachegrind to evaluate the result.
KCachegrind doesnt show me the names of my functions nor their source in the callgraph but of many of the Lazarus unit-files.
KCachegrind also tells me:
There is no source available for the following function:
'FPREADPNC$_$TFPREADERPNG_$
$$_DODECOMPRESS'
This is because no debug information is present.
Recompile source and redo the profile run.
The function is located in this ELF object:
'matrixtest'
The KCachegrind Configuration however says:
General

Context lines in annotations:

(always)
/dok/ny/p/hep/test/matrix/matrixtest
/lib/x86_64-linux-gnu/ld-2.23.so
/lib/x86_64-linux-gnu/libc-2.23.so
/lib/x86_64-linux-gnu/libdbus-1.so.3.14.6
/lib/x86_64-linux-gnu/libdl-2.23.so
......
My Lazarus project options are:

-Fu/E/ny/p/hep/helib

-Fu/usr/local/share/lazarus/lcl/units/x86_64-linux/gtk2

-Fu.

What can I do?
