• [x] ran brew update and can still reproduce the problem?
• [x] ran brew doctor, fixed all issues and can still reproduce the problem?
• [x] ran brew gist-logs <formula> (where <formula> is the name of the formula that failed) and included the output link?
• [x] if brew gist-logs didn't work: ran brew config and brew doctor and included their output with your issue?

What you were trying to do (and why)

Trying to run GDB against binaries with LZMA compressed debugging symbols.

What happened (include command output)

GDB prints out the following warning:

warning: Cannot parse .gnu_debugdata section; LZMA support was disabled at compile time

GDB configuration shows that it was compiled --without-lzma

Command output

warning: Cannot parse .gnu_debugdata section; LZMA support was disabled at compile time,

gdb> show configuration
This GDB was configured as follows:
   configure --host=x86_64-apple-darwin19.3.0 --target=x86_64-apple-darwin19.3.0
             --with-auto-load-dir=:${prefix}/share/auto-load
             --with-auto-load-safe-path=:${prefix}/share/auto-load
             --with-expat
             --with-gdb-datadir=/usr/local/Cellar/gdb/9.1/share/gdb (relocatable)
             --with-jit-reader-dir=/usr/local/Cellar/gdb/9.1/lib/gdb (relocatable)
             --without-libunwind-ia64
             --without-lzma
             --without-babeltrace
             --without-intel-pt
             --without-mpfr
             --without-xxhash
             --with-python=/System/Library/Frameworks/Python.framework/Versions/2.7
             --without-guile
             --disable-source-highlight
             --with-separate-debug-dir=/usr/local/Cellar/gdb/9.1/lib/debug (relocatable)

  

What you expected to happen

GDB can load the symbols due to being compiled with LZMA support

Step-by-step reproduction instructions (by running brew install commands)

1. brew install gdb
2. inside gdb run show configuration
3. look for --without-lzma

Workaround

Reinstall gdb from source, making sure the xz package (with liblzma) is installed.

Example: brew reinstall -s gdb
