Re: [Valgrind-users] .gcda files are not generated when run on valgrind

[Ravi K. <rav...@gm...>]

Hi,


>>>>What is the smallest program which fails?  Post it here (the source and the build recipe).
If you cannot do that, then tell us its characteristics.
Such as: CPU architecture, compiler and version, C runtime library and version,
size of executable ("/usr/bin/size my_app"), number and size of shared libraries
("/usr/bin/ldd my_app", then 'size' of each library), duration of execution
("time ./my_app arg1..."; telling us "a lot of time", without
quantifying it, is useless).

   Below are the required details:

CPU Architecture : x86_64
Compiler and version : gcc version 4.6.2 (GCC)
C runtime library and version : libc.so 2.11.1
Number and size of shared libraries : 24 & 8 M.B
Valgrind version : valgrind-3.9.0
Execution time : 10 - 12 hours
Gcov version : gcov (GCC) 4.6.2

CFLAGS += "--coverage -fno-inline -fprofile-arcs -ftest-coverage"
LDFLAGS += "-lgcov"


I'm working on the small test case with this issue . I will be back with
example at the earliest

Thanks,
Ravi
