QUESTION
Here is a crude example of the type of code I would like to use libtool's libltdl dlpreopening with:
https://github.com/EmmaJaneBonestell/dlopen-sample
I wish to be able to rewrite various projects that use libdl functions ( dlopen, dlsym, etc ), to instead use libtool's libltdl dlpreopening/preloading mechanism. From libtool's documentation, it will instead link the objects at compile time, resulting in truly static executables. It was intended for systems that do not support dynamic loading.
If you use it to compile and link these objects, libtool will run some of its scripts, and create the necessary data structures, and I believe perform mangling and demangling, to allow for duplicate symbol names.
Even after looking at the examples in libtool's source code, reading its entire documentation, and looking at relevant tests from the test-suite (e.g. tests 118 & 120), I've been unable to do so.
Outside of libtool itself, there is essentially no mention of this functionality anywhere I could find. I did manage to see it used in a too-complex-for-me manner in Graphviz, but there's little documentation on that either.
I'm really not much of a programmer, more of a tinkerer. It's easy enough for me to use libltdl for a wrapper for standard dlopen/dlsym.
I think my main issue is figuring out how I can return a proper handle for a preopened object, though I may be doing other things incorrectly.
The documentation states that lt_dlopen can work on preloaded static modules, but it doesn't seem to accept any possible reference to it I could imagine.
I would also prefer not to have to even invoke libtool, but c'est la vie.
I didn't bother including any of what I've tried code wise (on the example) because I've tried such a mess of things that I feel it would really just be confusing to show it.
Current libtool documentation: https://www.gnu.org/software/libtool/manual/libtool.html
...ANSWER
Answered 2021-Jun-10 at 17:17Apparently libtool requires the .la file to be present and have its rpath properly declared, even though it won't be used for anything in this truly-static binary.
Libtool's documentation makes fairly clear that your "module" files should contain the following preprocessor macro for all symbols to be exported.
QUESTION
What is the best way to scale and center a graph using d3-graphviz? I was hopeful that I could use scale(0.5) but this leaves the resulting graph uncentered.
I could probably go in with an .attributer() and manually adjust the and elements to get what I'm looking for, but I figured there was probably a better way?
ANSWER
Answered 2021-Jun-02 at 20:49There's no simple built-in way, but you can achieve almost anything with the attributer like so:

In this answer, there are edges with :e and :w in the code:
ANSWER
Answered 2021-Jun-08 at 00:15See https://www.graphviz.org/doc/info/attrs.html#k:portPos
Ports are used to explicitly position head/tail of edges. Ports are specified by compass points n(north), sw (southwest), etc and denote where on a node the edge is to terminate.
QUESTION
Does a tflite file contain data about the model architecture? A graph that shows what operations there where between the weights and features and biases, what kind of layers (linear or convolutional etc), size of layers, and what activation functions are there in-between the layers? For example a graph you get with graphviz, that contains all the information, or does a tflite file only contain the final weights of the model after training?
I am working on a project with image style transfer. I wanted to do some research on an existing project, and see what parameters work better. The project I am looking at is here:
I can download a tflite file, but I don't know much about these files. If they have the architecture I need, how do I read it?
...ANSWER
Answered 2021-Jun-07 at 01:31TFLite flatbuffer files contain the model structure as well. For example, there are a subgraph concept in TFLite, which corresponds to the function concept in the programming language and the operator nodes also represent a graph node, which takes inputs and generates outputs. By using the Netron application, the model architecture can be visualized.

ANSWER
Answered 2021-Jun-05 at 21:44There are two challenges
- find a way to display the vertical ellipsis (the three dots)
- keep the original nodes displayed in the desired order and location
The following works on my computer if output is SVG, but not png. If SVG is OK by you, here goes. If you need to directly create a png, an embedded image works.
QUESTION
I like to add a feedback arrow to a Graphviz graph, where the ordinary "flow" remains horizontal, but the feedback should be round, like the manually added blue arrow below.
Here is what I tried so far. I use the DiagrammR package for the R language but a suggestion for plain or python Graphviz or would of course also be helpful.
...ANSWER
Answered 2021-May-28 at 19:22You can try using the headport and tailport options and indicate "north" for both of these (for Population and Growth).
The headport is the cardinal direction for where the arrowhead meets the node.
The tailport is the cardinal direction for where the tail is emitted from the node.
QUESTION
I'm creating a Graphviz graph using an SVG document as the node shape. I'd like to assign port identifiers to parts of that shape and then define edges that start or end at a port. Is this possible?
So far, I've got this SVG document:
...ANSWER
Answered 2021-May-26 at 22:17Simple answer: no. Graphviz does not allow custom nodes via SVG (but a nice idea)
Alternatives:
- add this function to the codebase (just saying)
- use your SVG nodes, but draw custom edges yourself. Straight edges are pretty easy. Maybe this can be automated if you need to repeat.
- your node is quite simple. recreate it as two rectangles inside a cluster. define ports and dot will do the rest.
- recreate your node as a single HTML-like node. again define your ports and let dot take over.

QUESTION
I'm trying to add a target to generate API doc with Doxygen to my CMake project by find_package(Doxygen ...) and doxygen_add_docs(). I'm in a MSYS2 environment on Windows 10. For some reason CMake and Doxygen seem to not handle paths in the expected way (see the example).
At first, Doxygen complains that it cannot create the output directory. The DOXYGEN_OUTPUT_DIRECTORY prepared by CMake is a Windows path with regular forward slashes. Doxygen seems to not recognize this as an absolute path and prepends it with its working directory in the Unix format (/c/Users/...). I tried this by executing the generated target as well as calling Doxygen manually with the generated Doxyfile.doc. It works if I convert the path to a Unix path with cygpath.
The second problem is about finding dot. I have GraphViz installed as a native Windows package and generally the MSYS2 CMake finds this. Then, in the FindDoxygen.cmake DOXYGEN_DOT_PATH is set as the path portion of the dot executable and is modified by file(TO_NATIVE_PATH ...) because I'm on Windows. Trying this manually I could see that it sets that path to "C:/Program Files (x86)/Graphviz/bin" and converts it to "C:/Program\ Files\ (x86)/Graphviz/bin". The latter ends up in Doxyfile.doc. If I remove the backslashes there, it works. I suppose Doxygen considers these backslashes which are meant to escape the spaces as path separators.
For the first problem I have a (hopefully) portable workaround, but the second I can only fix if I manually repeat the retrieval of DOXYGEN_DOT_PATH from the Find module without the conversion step. This doesn't feel like a good solution.
Do I miss something here about path handling in CMake, e.g. some documentation or setting/policy?
Is this anyways the expected behavior, esp. for file(TO_NATIVE_PATH ...), in MSYS2?
Very basic example: Just a CMakeLists.txt to generate Makefiles and invoke Doxygen. The output of make doc shows the 2 problems described above - the error is for #1, the warning for #2.
CMakeLists.txt
...ANSWER
Answered 2021-May-20 at 12:45It turned out that the proper Doxygen package was not installed in the MSYS2 environment.
I use the MinGW64 shell, which uses the binaries from the mingw-w64-x86_64-* packages. The CMake output from the question shows that the binaries for the C and CXX compilers are under C:/msys64/mingw64/ (as well as the CMake binary) while Doxygen is in C:/msys64/usr/bin/.
Installing mingw-w64-x86_64-doxygen solved the issue. Now, the CMake output shows the mingw64 path also for Doxygen in the MSYS2 MinGW64-bit shell and API doc generation works flawlessly. Trying the MSYS2 MSYS shell also works fine with CMake using binaries from C:/msys64/usr/bin/.

Answered 2021-May-20 at 09:47You can align the nodes using a strong ("heavy") link, an invisible edge, between the last element of the first and the first element of the second node.
Add this line as the last one to your HTML-like code (which gives you much more flexibility than record shapes)

Vulnerabilities
Install graphviz
You can use graphviz like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
