| at least with r2000 `BLOCK_HEADER.first_` and `last_entity` is totally unreliable, at least for the very last block. So iterate over all ownerhandles and check them instead.
Also `get_next_owned_block()` is wrong for dxf BLOCKS, use a new `get_next_owned_block_entity` instead. We need all block entities, not just its INSERT subentities.

| Hello @rurban,
sorry for the simple question: i'm a complete newby. I downloaded the windows nightly at https://github.com/LibreDWG/libredwg/releases.
But I have no idea on where i should put the files to make them available in FreeCAD (EDIT and use the functions through its python console).
Any avice?
thx :)

| This post is listed in the order of questions first followed by specs, problem descriptions, and information.
### Questions:
1. What perl module is needed to get past the make check error shown below?
(see the "04 output:" of the "Description of the problem:" section shown below.)
2. What does the error message about the undefined symbol in line 187 of the DynaLoader.pm file mean and is this significant or can this be ignored for now?
(see the "Make check error examined:" section near the bottom)
3. Please let me know if I can provide anything else that might be helpful for figuring this out. Thanks.
### Specs:
**OS:** Linux
**Desktop:** Xubuntu 18.04.4 LTS
**Bash version:** 4.4.20(1)-release (x86_64-pc-linux-gnu)
**Perl version:** 5.26.1-6ubuntu0.3
**Dependencies installed:**
- TeXinfo for building the docs
- pslib for dwg2ps: http://pslib.sourceforge.net/doc/pslib.html
- pcre2 with 8bit and 16bit libraries for dwggrep regexp support
- SWIG 1.7+
- Python 2.7 or 3.x development headers (debian: python-dev; yum: python-devel)
and the libxml2 python bindings.
- Perl 5 for the perl bindings
- doxygen to generate the reference manual
- jq to check json validity
- valgrind to find leaks and memory bugs
- timeout to help tests with large or hanging DWG's
- GNU parallel to speed up special tests
**Dependencies not installed:**
- picat
The above package was not installed due to not being available by default in the apt-cache repositories.
### Description of the problem:
**Steps taken:**
**01 command:** sh ./autogen.sh
**01 outcome:** no errors.
**02 command:** ./configure
**02 outcome:** no errors, config looked ok.
**03 command:** make
**03 outcome:** Two possible errors listed, both with the same message:
> make regen-dynapi might be needed
***Here is the truncated make output:***
- Paths and successful make blocks have been truncated for readability.
- Make message blocks are shown in the order received.
- Note that "all-am" passes the "make regen-dynapi might be needed" message, but then completes successfully without this error in a later message block.
- Note that "perl" shows no errors.

| FreeCAD now allows to export dwg's with libredwg if libredwg is available. We cannot make libredwg a hard dependency because of license issues (lgpl2 vs gpl3) but using it as an optional dependency should not be a problem.
We use the dwg2dxf command for importing dwgs and dxf2dwg for the export. The import seems to work for most objects. But the export has bigger issues:
```

So regarding this message dxf2dwg is not ready to use yet. Would be nice to get some feedback how much is missing for a working dxf2dwg and if there is anything testers/users can do to accelerate this process?

| It seems layer names in the format "ABCD(space)ABDC" are being renamed to "ABCD_ABCD" where any space char is replaced by a "_" char.
Sample file attached and screenshot inside AutoCAD comparing to the dwglayers.exe output.
It seems the issue doesn't have to do with dwglayers app itself.
Maybe something with this code (dwg_api.c):
`bit_convert_TU ((BITCODE_TU)layer->name);`

| Hi,
I'm trying to run the dwglayers.exe app with some DWG files.
It works just fine when called via BAT command but when called from a .NET app using Process class it works sometimes and fails to get information from some dwg files.
```
ProcessStartInfo objStartInfo = new ProcessStartInfo();
objStartInfo.FileName = "dwglayers.exe";
objStartInfo.Arguments = string.Format("\"{0}\"", "MyDwgFile.dwg");
objStartInfo.RedirectStandardOutput = true;
objStartInfo.UseShellExecute = false;
objStartInfo.CreateNoWindow = true;
try
{
List<string> lstResult = new List<string>();
using (var objProcess = new Process())
{
objProcess.EnableRaisingEvents = true;
objProcess.StartInfo = objStartInfo;
objProcess.OutputDataReceived += (sender, e) =>
{
if (string.IsNullOrWhiteSpace(e.Data))
return;
if (e.Data.Trim() == "0")
return;
if (!lstResult.Any(sItem => sItem.Equals(e.Data, StringComparison.InvariantCultureIgnoreCase)))
lstResult.Add(e.Data);
};
objProcess.Start();
objProcess.BeginOutputReadLine();
objProcess.WaitForExit();
}
}
catch (Exception excError)
{
}
```
It seems dwglayers.exe doesn't fill the output before exiting (or maybe doesn't flush the output properly).
The odd behavior is that for some drawings this code works just fine.
I'm attaching a DWG that can be successfully run via BAT but can't with this code.
It should list the following layers:
0
AFUWS-P
AFUWS-P-TN
Thank you.

| I use 0.9 version of libredwg to decode a R2000 version of DWG file and draw all entities in the Dwg_Data, and find that there are some ARCs missing.
Here is a comparison between the results of my program drawing and the results of commercial software display.
Before I decode, I use AutoCAD to decompose the drawings. I checked the properties of arcs that are not displayed, and there is no difference between them.
The test file is here:

| Hello, I tested version 0.9 and I have the following problems:
I have provided two dwg files, tmp1.dwg and tmp2.dwg.
The tmp1.dwg file contains the shx font. The text content is well preserved when exporting, but all the characters are replaced with truetype fonts. So after dwg is converted into svg, many style changes have occurred. Can it still be shx font style restore?
tmp2.dwg contains a small amount of drawing content, but after switching out to svg, it does not see any content. I tried to use dwg2dxf to convert to dxf. At this time, I get the following error message.

| Hi,
When I convert dwg to dxf, I noticed that there are some problems below :
-1 missing entity in Block reference.
- Entity color is converted ByBlock instead of ByLayer or RGB,
- BLOCKINSERT is missing,
- Some error messages in some dwg files.
Simple test file is attached,
Thanks

It looks expensive, timings:
```
without with
make check 0m12.034s 0m12.303s
(mostly -v2)
./logs-all.sh 0m35.934s 0m37.324s
(only -v4)
```
so it's neglectable.

| Consider attached [patch](https://github.com/LibreDWG/libredwg/files/3388944/decode-endian-fixes.txt). It might not be perfect and I've only tested it under FreeBSD (`#include <sys/endian.h>`), so some adjustments are most certainly in order for GNU/Linux and other systems, but it seems to fix R2004 decoding and allow to pass those tests.

| Hi,
The FIELDLIST object does not correctly decode it's field handles because there is an owerhandle, reactors and xdic handle read missing.
The following:
START_HANDLE_STREAM;
HANDLE_VECTOR (field_handles, num_fields, 0, 330); // 2 or 4, or 3.0.0
needs to change to (need to add ownerhandle to dwg_object_FIELDLIST
structure):
START_HANDLE_STREAM;
FIELD_HANDLE (ownerhandle, 4, 0);
REACTORS(4);
XDICOBJHANDLE(3);
HANDLE_VECTOR (field_handles, num_fields, 0, 330); // 2 or 4, or 3.0.0
Looking at the dwg.spec it seems to me that EVERY object should have:
START_HANDLE_STREAM;
FIELD_HANDLE (ownerhandle, 4, 0);
REACTORS(4);
XDICOBJHANDLE(3);
// Further object handles start here
before reading any other objects. Every object currently reads <num_reactors> and <xdic_missing_flag> so that says to me that these handles may exist at the start of the handles stream. I have tested this with several objects:
FIELD - Already in issue #117
FIELDLIST
MLEADERSTYLE - This needs the change I have suggested above
A quick search through dwg.spec for "START_HANDLE_STREAM" showed many inconsistencies.
For example, BLOCK_CONTROL (indeed all '_CONTROL' objects) had a missing REACTORS(4). Several other objects (such as TABLECONTENT) would start reading private object handles immediately after the START_HANDLE_STREAM.
I propose that a new macro is created called "START_OBJECT_HANDLE_STREAM" which simply expands to
START_HANDLE_STREAM;
FIELD_HANDLE (ownerhandle, 4, 0);
REACTORS(4);
XDICOBJHANDLE(3);
and that all objects call this instead of just START_HANDLE_STREAM;
Below is the extract from the ODA spec for what is at the end of every object:
Common
Below begins the handles stream, this begins at offset specified by number of bits before handles above
H Parent handle (soft pointer)
H [Reactors (soft pointer)], repeated as many times as specified by the number of persistent reactors
H xdictionary (hard owner), present if the has xdictionary flag is true
X Object specific handles
B* Padding bits are added until the next byte boundary is reached.
RS CRC
The CRC includes the size bytes. | FIELDLIST handles (and maybe many more objects) not decoded correctly | https://api.github.com/repos/LibreDWG/libredwg/issues/118/comments | 3 | 2019-07-05T09:25:48Z | 2019-07-07T18:52:58Z | https://github.com/LibreDWG/libredwg/issues/118 | 464,548,961 | 118 |

| Hi,
The FIELD object does not decode correctly because:
1) Data is read into unallocated memory area.
2) The handles are not read from the handle stream.
The following changes are needed:
DECODER { if (_obj->num_childs) _obj->num_childs--; }
//DEBUG_HERE_OBJ
HANDLE_VECTOR (childs, num_childs, 3, 360);
FIELD_BL (num_objects, 97);
HANDLE_VECTOR (objects, num_objects, 5, 331);
should change to: (The handles are read later, also the decrement of num_childs is not needed - there are num_childs handles later)
//DECODER { if (_obj->num_childs) _obj->num_childs--; }
//DEBUG_HERE_OBJ
//HANDLE_VECTOR (childs, num_childs, 3, 360);
FIELD_BL (num_objects, 97);
//HANDLE_VECTOR (objects, num_objects, 5, 331);
then:
REPEAT_N((long)FIELD_VALUE(num_childval), childval, Dwg_FIELD_ChildValue)
should change to: (The memory needs to be allocated for the child values)
REPEAT(num_childval, childval, Dwg_FIELD_ChildValue)
and finally, add the following field to dwg_object_FIELD structure:
BITCODE_H ownerhandle;
and then add the following to the end of the decode spec so that the handles can be read:
START_HANDLE_STREAM;
FIELD_HANDLE (ownerhandle, 4, 0);
REACTORS(4);
XDICOBJHANDLE(3);
HANDLE_VECTOR (childs, num_childs, 3, 360);
HANDLE_VECTOR (objects, num_objects, 5, 331);
