Hi
I am using Fedora 37. I am debugging a C program using OpenSSL API with the OpenSSL compiled with debug flags from the source on the OpenSSL download site.
$ ./Configure --prefix=$HOME/.local/openssl-3.0.8-fips-debug --libdir=lib shared linux-x86_64 enable-fips -O0 -g3 -ggdb3 -gdwarf-5
$ make -j4
$ make install
Now I want to see the called functions in the both the program and the openssl . It seems that the strace
only prints the system calls, and ltrace
prints the top of the functions.
$ LD_LIBRARY_PATH=/home/jaruga/.local/openssl-3.0.8-fips-debug/lib/ \
OPENSSL_CONF=/home/jaruga/.local/openssl-3.0.8-fips-debug/ssl/openssl_fips.cnf \
a_command ...
I found the example of using the dtrace
below. This looks nice. The answer is in November 2021. It’s still new. However the dtrace -F
option used in the example doesn’t exist.
$ rpm -qf /bin/dtrace
systemtap-sdt-devel-4.8-1.fc37.x86_64
So, could you recommend me a command to print the called functions nicely on Fedora? Perhaps, dtrace
with different options or systemtap can be used?
Thanks!
