bamtools Installation error

[thugib]

I am working on Rocky Linux v 9.6 and am getting an error when I try to install whamg using the command: git clone --recursive https://github.com/zeeev/wham.git; cd wham; make

This is the partial, last part, of the output:

AI is telling me to fix :

bool operator()(const BamAlignment& lhs, const BamAlignment& rhs)  {
    // comparison logic

}
or

bool operator()(const MergeItem& lhs, const MergeItem& rhs)  {
    // comparison logic
}

and add 'const' to them, as in :

bool operator()(const BamAlignment& lhs, const BamAlignment& rhs) const {
    // comparison logic

bool operator()(const MergeItem& lhs, const MergeItem& rhs) const {
    // comparison logic

}

However, I am having difficultly finding the above lines in the program.
