Bug ID: 50468 Summary: winedbg fails to load symbols for non PE builtin dlls Product: Wine Version: 6.0-rc5 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: minor Priority: P2 Component: dbghelp Assignee: wine-bugs@winehq.org Reporter: j-r@online.de Distribution: ---
While looking at an xactengine problem in Hyperdimension Neptunia ReBirth 1 (bug #50416) with a mingw enabled build (haven't tested a non mingw build; should I do that?) winedbg fails to load symbols from e.g. x3daudio1_7 and xactengine3_7.
Interestingly symbols for x3daudio (directly linked to by the main exe while xactengine is loaded on demand through CoCreateInstance) are available when using winedbg --gdb.
+dbghelp log doesn't seem very interesting to me (no debug info in the dll and no matching .pdb found). Should it be uploaded anyway? Which debugger commands should I use during the log session? Which other debug channels should I turn on to provide further info?

--- Comment #1 from j-r@online.de --- Created attachment 69100 --> https://bugs.winehq.org/attachment.cgi?id=69100 add shared object load address tracing for builtin dlls to loaddll debug channel
In the meantime I've been using the attached patch to print the base address of each dlopen()ed shared object to make using add-symbol-file easier. Couldn't find a way to determine the .text section start address. This info doesn't seem to be preserved by the dlopen() interface. Might be useful anyway.

The issue does not only apply to dlls, but also ELF executables. This document includes information about compiling and "debugging" the binary.

just tested on installed wine, this works as expected (both 32 and 64 compilations)
