Description Igor Raits 2019-04-02 09:58:09 UTC

Latest gdb-headless started to pull source-highlight which pulls ctags and boost-regex and libicu. Which means that buildroot size increased from:

DEBUG util.py:439:  Install  146 Packages
DEBUG util.py:439:  Total download size: 63 M
DEBUG util.py:439:  Installed size: 235 M

to:

DEBUG util.py:556:  Install  151 Packages
DEBUG util.py:556:  Total download size: 76 M
DEBUG util.py:556:  Installed size: 342 M

Is it really necessary to have in gdb-headless?

Comment 1 Sergio Durigan Junior 2019-04-02 17:29:03 UTC

The problem here is that we only ship one GDB binary, which is in gdb-headless, and this binary pulls in all these dependencies.  So yeah, unfortunately (for buildroot) it is necessary for GDB to depend on source-highlight, assuming we want to ship a GDB with source highlight activated for the user (which we do).

Perhaps one option to reduce the buildroot size is to create a "boost-regex-devel" package, which only pulls the necessary development headers for boost-regex.  I don't know how feasible that is.

Another option is to create a "gdb-minimal" package, which only offers the bare minimum necessary for the buildroot.  This would be the best way, I think, because it would allow us to remove even more dependencies from GDB that "pollute" the buildroot nowadays.  I can't promise anything now, but I will try to work on that.

I do not believe this will change anything, 'ldd /lib64/libboost_regex.so' itself already brings in libicu.

Requires are generated from *.so dependencies (DT_NEEDED).

Comment 3 Sergio Durigan Junior 2019-05-01 22:30:42 UTC

The gdb-minimal package has been created and is now available to be used in the buildroot.

Igor and I are proposing the following change to Fedora buildroot:

I am therefore closing this bug.
