dwg 2019: Invalid comp_bytes 4 > 3 bytes left (vs 3) #918

Mannshoch · 2024-01-08T10:53:13Z

I compiled libredwg for converting with dwg2dxf on a Ubuntu 23.10

If I run dwg2dxf file2019.dwg file2019.dwg
I get this Error:

Reading DWG file file2019.dwg

If I open AutoCAD and convert it into v2000, and try it again. I get this error:

@Mannshoch Could you present the command which you use?
This is strange:

READ ERROR 0x440
Reading DWG file file2019.dxf
ERROR: File not found: `file2019.dxf`

You are reading dwg file not dxf file.

Which version of libredwg do you use?
DWG file is AC1032?

rurban · 2024-01-11T11:05:16Z

Can you send me your file2019.dwg? I need to have a look if it's a wrong overflow error, or some other problem with the section_map

Mannshoch · 2024-01-12T10:05:09Z

Sorry, I'm not allowed to publish that dwg. If you give me advice I will collect data and send them to you.

@Mannshoch Ah, I see, what you are doing.
Right command is:

dwg2dxf 'File-2010.dwg' -o 'File.dxf'

michal-josef-spacek · 2024-01-20T14:32:55Z

@Mannshoch

Which version of libredwg do you use?

Version: dwg2dxf 0.12.5-1549-g2eebb566

This is something bad :-)
Actual version is 0.12.5.6939

Mannshoch · 2024-01-22T11:32:16Z

Sorry, I'm not so skilled in Git.

I followed this advise from FreeCAD for compiling
https://wiki.freecad.org/FreeCAD_and_DWG_Import
After Git pull and recompileI have still: dwg2dxf 0.12.5-1549-g2eebb566

If I try it from Github: git@github.com:LibreDWG/libredwg.git I get a

Cloning into 'libredwg'...
git@github.com: Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

so I assume https://git.savannah.gnu.org/git/libredwg.git is still correct?

michal-josef-spacek · 2024-01-22T12:29:53Z

@Mannshoch There are some facts:

Intensive development, so prebuilt binaries could be obsolete :-)
If you have Windows and you don't want to compile, look to https://github.com/LibreDWG/libredwg/releases . I tested the last Windows dev release on Wine and it's running. 0.12.5.5877

> wine dwg2dxf.exe --version
dwg2dxf 0.12.5.5877

ad git) git clone https://github.com/LibreDWG/libredwg.git

Mannshoch · 2024-01-22T15:11:51Z

I compiled it from the
libredwg-0.12.5.6939.tar.gz file. I use Ubuntu.

Hmm, fine. I haven't any DWG files with these errors.

michal-josef-spacek · 2024-01-23T15:18:52Z

@Mannshoch
If you don't want to share the whole file, you can share a piece of the log record around the error.
dwg2dxf -v3 'File-2019.dwg' -o 'File.dxf' for more logs and find ERROR inside.

Same with dwgread -v3 'File-2019.dwg'

A DXF is not created.

I have here a running AutoCAD 2019
If you wish I could also do something on this application.

File-2019 has 675MB in on Disk.
On AutoCAD I did:

Audit

Auditing Header
Auditing Tables
Auditing Entities Pass 1
Pass 1 2000    objects audited
Auditing Entities Pass 2
Pass 2 2000    objects audited
Auditing Blocks
 6       Blocks audited
Auditing AcDsRecords
Total errors found 0 fixed 0
Erased 0 objects

then I purged the File and did a Recover
The File has now 311MB

but dwg2dxf still has an Error and do not create a DXF:

These sizes are too big, right?

No, sounds valid to me
