Hello, I followed instructions in the "Usage with ABI Dumper" section of the index.html documentation, since this usage is very convenient. I built the library (libpetsc.so) with "-g -Og" on a Linux machine with gcc. Then,

~/abi-dumper/abi-dumper.pl ~/old/linux-gnu-dbg/lib/libpetsc.so -lver 0 -o old.dump
ERROR: missed type id 713704

Creating ABI dump
The object ABI has been dumped to:
  old.dump

~/abi-dumper/abi-dumper.pl ~/new/linux-gnu-dbg/lib/libpetsc.so -lver 1 -o new.dump

~/abi-compliance-checker/abi-compliance-checker.pl -l libpetsc -old old.dump -new new.dump

But actually, the new library is not API compatible with the old since it changed the name of an enum. So, what is the recommended way of using abi-compliance-checker.pl if I want very accurate results. Thank you.

Hi,

The library has been added to the ABI tracker. See daily reports here: https://abi-laboratory.pro/?view=timeline&l=petsc

It works in my environment: CentOS 7 / x86_64.

Please provide the output of the following command for debugging:

abi-dumper -extra-info ./DEBUG ~/old/linux-gnu-dbg/lib/libpetsc.so -lver 0 -o old.dump
tar -cJf DEBUG.txz ./DEBUG

Also please provide your Linux distribution version.

Thanks.
