compiling for debug on Linux
I know this is a FAQ, but the answers I found all included the response that didn't work. openssl 1.0.1c on Linux: How do I compile and link so the debugger can step into the openssl code? Are there definitive instructions anywhere, or does everyone use trial and error? I'm using a local copy of the source, and do not want to touch /usr/bin. I tried various combinations that worked in the past: ./config with -d -g shared linux-elf --prefix ... ./Configure with the above and -shared debug-linux-elf They either didn't compile, didn't link, or gdb would not step in. __ OpenSSL Project http://www.openssl.org User Support Mailing Listopenssl-users@openssl.org Automated List Manager majord...@openssl.org
Compiling for debug
I'm trying to compile openssl for: Linux, 32-bit on a 64-bit machine, shared libraries, and debug. The closest I found was: ./Configure linux-elf -m32 -shared -g but this still does -O3, and the optimizer doesn't work well with the source level debugger. Any clues for changing -O3 to -O0? ~~ Bonus meta-question: When does one use ./Configure vs. ./config? The documentation shows examples of both, but doesn't explain the difference. __ OpenSSL Project http://www.openssl.org User Support Mailing Listopenssl-users@openssl.org Automated List Manager majord...@openssl.org

For debug builds, you will likely want -g3 -ggdb -O0. You should also define -DDEBUG=1 (and make sure -DNDEBUG=1 is *not* defined). -g3 provides maximum debugging information. For example, symbolic constants through #define's will be available. -ggdb provides gdb extension. I don't believe there are any at the moment, but I got into the habit of using it (in case they show up in the future). NDEBUG is Posix C and used for Release builds, so it should be undefined. Some libraries/implementation sneak in additional code when DEBUG is defined, so I define it. Sorry about not answering your original question :( Jeff

The config script mainly auto detects the system type and passes the results to Configure which actually does the platform specific configuration. The -d option to config tries to use a debug build and actually prepend debug- to the platform. So try debug-linux-elf -m32 shared Steve. -- Dr Stephen N. Henson. OpenSSL project core developer.

Problem compiling with debug option in OpenSuSE 10.2
Hi all,
I'm trying to compile OpenSSL-0.9.8c with debug option, but some
errors shown below occurs :

(Then stop..)
Can anyone tell me how to solve it? (I've tried to compile without
debug option and I didn't find any trouble. OpenSuSE 10.2 use gcc
4.1.2)
