no debugging symbols found (not the simple case)
Hello all,
I wasn't sure where to put this so if I need to move it just let me know. I have a strange problem that I cannot figure out. When I use gdb to debug our rpm-installed program, it says (no debugging symbols found) when it loads. Thing is, when I use nm on the program it can print the symbols, and even stranger is if I use gdb on the program before it is packed up by rpmbuild it loads the debug symbols just fine. Our program is built via the standard make using: CFLAGS=-g -Wall -pedantic and as I mentioned I can debug the resulting program. After the build, I package it up using: cmd="rpmbuild -v -bb ptsnmp.spec --define \"ver ${cmvc_release}\" --define \"rel ${cmvc_level}\" --define \"_topdir $rpmdir\"" When this package is installed via rpm, the binary on the machine shows all the debug info via nm, file shows it is not stripped: pt_snmp: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GN U/Linux 2.6.9, not stripped yet when I try to debug it I get the no debugging symbols found. This is really taxing my brain and I am sure I am just missing something, so if anyone has a clue as to what the problem could be I would appreciate it very much. Thanks for any help. |
Are the -devel or (-debuginfo if there is one) libraries installed on the new host?

ok, I found the bin from the package file was MUCH smaller, over 3x smaller in fact. So, I checked the logs and found:
+ /usr/lib/rpm/redhat/brp-compress + /usr/lib/rpm/redhat/brp-strip /usr/bin/strip + /usr/lib/rpm/redhat/brp-strip-static-archive /usr/bin/strip + /usr/lib/rpm/redhat/brp-strip-comment-note /usr/bin/strip /usr/bin/objdump + /usr/lib/rpm/brp-python-bytecompile + /usr/lib/rpm/redhat/brp-java-repack-jars So, even though it says the bin is not stripped using file it looks like it really might be. At least I assume that is what rpmbuild is doing in those calls. Is there a way to prevent rpmbuild from stripping the bins? |
Found the answer, I can use "%define __os_install_post %{nil}" to prevent the stripping. It now works like I want.
