Unable to compiler egalito about egalito HOT 8 OPEN

You need the libc and libstdc++ debug packages. On your system, it should be libc6-dbg and libstdc++6-7-dbg. Please try installing those and doing a clean rebuild.

from egalito.

I have those libraries.

It looks like Ubuntu 20.04 has moved away from .build-id references for debug files, and starting to use full paths (like Fedora). Egalito handles both but Ubuntu's GDB doesn't seem to be configured that way. I added a hack to the ubuntu20.04 branch to work around this until GDB can find symbol files properly.

Thank You! did make some progress. But, could not build it.

Here is the error.

It's doing code generation. Look at generate1.cpp for example. Every time it can't find a debug package gdb will print an error message and that ends up in the code instead. Try adding

add-symbol-file /usr/lib/debug/lib/x86_64-linux-gnu/libc-2.31.so

to dep/rtld/symbols.gdb. You can also test with

gdb /lib/x86_64-linux-gnu/libc-2.31.so
gdb /lib/x86_64-linux-gnu/ld-2.28.so

Basically, those two have to find symbols.

I'm still having issues with Ubuntu 20.04. However, I'm able to compile it fine in Ubuntu 18.04. Thank you!

The "dep/rtld" doesn't do make clean very well unless you explicitly go to that directory. To avoid problems, you can clone again from scratch. Glad 18.04 worked.
