[Bug 55964] New: wine-mono: Dlls include reference to filenames different to the files in wine-mono-8.1.0-dbgsym.tar.xz
https://bugs.winehq.org/show_bug.cgi?id=55964 Bug ID: 55964 Summary: wine-mono: Dlls include reference to filenames different to the files in wine-mono-8.1.0-dbgsym.tar.xz Product: Wine Version: 8.19 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: mscoree Assignee: wine-bugs(a)winehq.org Reporter: bernhardu(a)mailbox.org Distribution: --- I was trying get a backtrace from #55736 with debug symbols. Therefore I tried using a windows build of LLDB. Unfortunately it took me some time to figure out that the PDB file name embedded in the dll files did not match the filename in the archive wine-mono-8.1.0-dbgsym.tar.xz. After renaming to the name libmonosgen-2.0.pdb it got found by LLDB. Maybe either the build can be modified to build with the expected file names in the first place, or add a short readme to the archive file describing this issue? $ strings windows/mono/mono-2.0/bin/libmono-2.0-x86*.dll | grep -i "mono.*\.pdb" /vagrant/build/mono-x86_64/mono/mini/.libs/libmonosgen-2.0.pdb /vagrant/build/mono-x86/mono/mini/.libs/libmonosgen-2.0.pdb -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=55964 --- Comment #2 from Esme Povirk <madewokherd(a)gmail.com> --- Are the debug symbols working OK otherwise? I never worked out how to use them. Unfortunately, it's hard to move/rename the libmono dll's because old Wine versions will look for them in the old place. I'm hoping it'll be possible to specify the pdb name in LDFLAGS at build time. Other dlls where we add the dll's architecture to the filename are likely to have the same problem. I think we should switch from e.g. lib/FAudio-x86.dll to lib/x86/FAudio.dll, as we do for some of the more modern ones. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

Are the debug symbols working OK otherwise? I never worked out how to use them.
LLDB was able to use, with environment LLDB_USE_NATIVE_PDB_READER=1 and native msdia140.dll it showed also inlined frames. So yes, the PDB itself works like a charm.
Unfortunately, it's hard to move/rename the libmono dll's because old Wine versions will look for them in the old place. I'm hoping it'll be possible to specify the pdb name in LDFLAGS at build time.
I do not want to change anything about the final "libmono-2.0-x86_64.dll" filename in existing or new wineprefixes. It is just the dll is built into filename libmonosgen-2.0.dll, therefore both x86 and x86_64 contain therefore the PDB reference to "libmonosgen-2.0.pdb". During install step it gets copied into image/bin/libmono-2.0-x86_64.{dll,pdb}, but the dlls still point to "libmonosgen-2.0.pdb". The relevant install step from "make bin": do_install () { cp "$(printf %s "$1"|sed -e 's/\....$/.pdb/')" "$(printf %s "$2"|sed -e 's/\....$/.pdb/')"; cp "$1" "$2" PATH=.../llvm-mingw-20210423-ucrt-ubuntu-18.04-x86_64/bin:$PATH x86_64-w64-mingw32-strip "$2"; }; do_install ".//build/mono-x86_64/mono/mini/.libs/libmonosgen-2.0.dll" ".//image/bin/libmono-2.0-x86_64.dll" -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=55964 --- Comment #5 from Bernhard Übelacker <bernhardu(a)mailbox.org> --- Would a plain text replacement by sed be acceptable? Attached patch would be called in do_install after the actual copy, and tries to replace the pdb name, without changing file size. This would modify: libmono-2.0-x86*.dll, MonoPosixHelper-x86*.dll libmono-btls-x86*.dll FNA3D-x86*.dll FAudio-x86*.dll -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=55964 --- Comment #7 from Esme Povirk <madewokherd(a)gmail.com> --- This should fix it for the libmono dll's: https://github.com/madewokherd/wine-mono/commit/2943bec61e8345f5ee91b13022e2... For the other dll's, I think it will be better to just remove the -arch from the name and move them to architecture-specific directories. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
