Unable to load native library on .NET8 #121

After upgrading from .NET 7 to .NET 8, generating pdf stopped working with the below error

Ok, so your issue was fixed?

muraczewski commented 8 months ago

Nope. It only fixed the below issue with building a docker image: image

HakanL commented 8 months ago

Ok, so it's most likely one of the dependencies for the native library that aren't met. Best is to try to get the command line version of wkhtmltopdf to work in your container, then this wrapper should work after that.

I'm also having issues on .NET 8, but only when deploying to an Azure App Service on Linux. I haven't tested the Azure App Service on Windows, but on my Windows dev computer it works fine.

I'm not sure if that helps diagnose anything... but I also don't know what workaround is possible in my scenario outside of switching to an App Service on Windows (which costs twice as much) or trying to find a solution with Docker and deploying to a Azure App Service on Linux with Docker.

nydsteven commented 8 months ago

I was able to get the list of installed dependencies on the Azure App Service on bash, and I still get the same error as mentioned @muraczewski even though libjpeg62 is installed on the machine. Here's all of the .NET 8 dependencies on the App Service (some are different than the .NET 7 app services).

Edit: please ignore the strikethrough, I'm not sure why that is being added to the list I copied from the command line

HakanL commented 8 months ago

Did you try the native wkhtmltopdf command line tool in this container/instance?

nydsteven commented 8 months ago

No, just the NuGet package published with my app to the app service. Thanks for your help, could you tell me where the command line tool info is? Sorry I didn't see it on the readme

HakanL commented 8 months ago

So this project is just a .NET wrapper around a native library. So when you're getting these exceptions it's most likely because the OS fails to load the native library (due to missing dependencies). Unfortunately native dependencies are a lot harder to troubleshoot than .NET, but that's the issue with using native libraries (there are no managed opensource HTML to PDF libraries available). A way to start the troubleshooting is to get the native library to work, then it should be easier to get this project to work. https://wkhtmltopdf.org/downloads.html

nydsteven commented 8 months ago

I see, that makes sense - thanks a ton for your help. I believe I used the native library in the past, if you happen to remember, is that where the extra dlls need to be deployed separately for it to work?

HakanL commented 8 months ago

There shouldn't be any extra DLLs needed, but there are primarily two things in play for the library to be loaded by .NET runtime. a) Find the native library (.NET has hard-coded search paths, like runtimes/native/win-xxx, etc) b) The OS tried to load all the dependencies for that native library (like libssl, libjpeg, of the exact version, libjpeg62, etc) If either of those fails then .NET (this project) only gets an error back saying "Failed to load".

So the OS has to have the exact native dependencies installed or it won't work. Some people "cheat" by installing a package (apt-get, etc) for the wkhtmltopdf, which will then pull in the native dependencies), but it's not required, you can just make sure the correct libraries are installed.

Your upgrade to .NET8 probably changed the installed native libraries (perhaps libssl) and that broke the wkhtmltopdf library.

nydsteven commented 8 months ago

Gotcha, thanks again for all of the info! I'll post back here if I can get it running/deployed on .NET 8

asaray11 commented 8 months ago

I am able to run it in .NET8 containers with the following lines in dockerfile:

FROM mcr.microsoft.com/dotnet/aspnet:8.0 AS base

RUN apt-get update && ln -s /usr/lib/libgdiplus.so /lib/x86_64-linux-gnu/libgdiplus.so RUN apt-get install -y --no-install-recommends zlib1g fontconfig libfreetype6 libx11-6 libxext6 libxrender1 wget gdebi RUN wget https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.5/wkhtmltox_0.12.5-1.stretch_amd64.deb RUN wget http://archive.ubuntu.com/ubuntu/pool/main/o/openssl/libssl1.1_1.1.1f-1ubuntu2_amd64.deb RUN dpkg -i libssl1.1_1.1.1f-1ubuntu2_amd64.deb RUN gdebi --n wkhtmltox_0.12.5-1.stretch_amd64.deb RUN ln -s /usr/local/lib/libwkhtmltox.so /usr/lib/libwkhtmltox.so

But I am not happy for using libssl1.1 since it has vulnerabilities and caught as vulnerable by trivy container scanner, trying to find a solution.

@nydsteven Hi, I am having the same issue, deploying dotnet8 app to azure linux webapp. dotnet 7 was working fine. Were you able to resolve the issue? Everything about the app is same except updated packages and changed runtime to DOTNET 8 image

nydsteven commented 8 months ago

@wapenshaw I still haven't found a workaround for an App Service that's not using Docker on Linux. But it seems like the libssl1.1 that @asaray11 mentioned is the issue, I've been working on compiling another binary that references libssl3 form linux-64 but haven't had any luck yet

This solution worked for me running on dotnet 7

PaulIvanov commented 7 months ago

I ran into this issue today as well. Looks like a dependency change from .net 6 to .net 8 causes this lib to break on non-docker linux based azure app services. @nydsteven out of curiosity, have you made any more progress on finding a workaround?

PaulIvanov commented 7 months ago

I was able to find a solution inspired by the docker solution above that @asaray11 posted. In the case of a non-docker linux azure app service container, I was able to modify the startup.sh file in the container via the KUDU advanced toolset.

Heres a brief article on how to modify the startup.sh so that it persists between deployments: https://azureossd.github.io/2020/01/23/custom-startup-for-nodejs-python/index.html

In the startup.sh file I added in the following content BEFORE it runs the project .dll:

apt-get update && ln -s /usr/lib/libgdiplus.so /lib/x86_64-linux-gnu/libgdiplus.so
apt-get install -y --no-install-recommends zlib1g fontconfig libfreetype6 libx11-6 libxext6 libxrender1 wget gdebi

I dont love this solution as it requires custom configuration in a hard to customize container, so I can see this solution breaking with little to no recourse if Azure App Service decides that this is not ok. If someone else finds a better solution, I'd love to hear about it.

ฉันสามารถเรียกใช้มัน .ภาชนะบรรจุ NET8 ที่มีบรรทัดต่อไปนี้ใน dockerfile:

จาก mcr.microsoft.com/dotnet/aspnet: 8.0 AS base

RUN apt-get update && ln -s /usr/lib/libgdiplus.so /lib/x86_64-linux-gnu/libgdiplus.so RUN apt-get install -y - ไม่มีการติดตั้งแนะนํา zlib1g fontconfig libfreetype6 libx11-6 libxext6 libxrender1 wget gdebi RUN Wget https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.5/wkhtmltox_0.12.5-1.stretch_amd64.deb RUN Wget http://archive.ubuntu.com/ubuntu/pool/main/o/openssl/libssl1.1_1.1.1f-1ubuntu2_amd64.deb RUN dpkg -i libssl1.1_1.1.1f-1ubuntu2_amd64.deb RUN gdebi --n wkhtmltox_0.12.5-1.stretch_amd64.deb RUN ln -s /usr/local/lib/libwkhtmltox.so /usr/lib/libwkhtmltox.so

แต่ฉันไม่มีความสุขกับการใช้ libssl1.1 เนื่องจากมีช่องโหว่และถูกจับได้ว่ามีความเสี่ยงจากเครื่องสแกนคอนเทนเนอร์ขนาดเล็กพยายามหาวิธีแก้ปัญหา.

I use and Terminal is Error how to Fix? 1.938 ln: failed to create symbolic link '/lib/x86_64-linux-gnu/libgdiplus.so': No such file or directory

My Project is FROM mcr.microsoft.com/dotnet/aspnet:7.0 AS base I use MAC os

I was able to find a solution inspired by the docker solution above that @asaray11 posted. In the case of a non-docker linux azure app service container, I was able to modify the startup.sh file in the container via the KUDU advanced toolset.

Heres a brief article on how to modify the startup.sh so that it persists between deployments: https://azureossd.github.io/2020/01/23/custom-startup-for-nodejs-python/index.html

In the startup.sh file I added in the following content BEFORE it runs the project .dll:

apt-get update && ln -s /usr/lib/libgdiplus.so /lib/x86_64-linux-gnu/libgdiplus.so
apt-get install -y --no-install-recommends zlib1g fontconfig libfreetype6 libx11-6 libxext6 libxrender1 wget gdebi
wget https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.5/wkhtmltox_0.12.5-1.stretch_amd64.deb
wget http://archive.ubuntu.com/ubuntu/pool/main/o/openssl/libssl1.1_1.1.1f-1ubuntu2_amd64.deb
dpkg -i libssl1.1_1.1.1f-1ubuntu2_amd64.deb
gdebi --n wkhtmltox_0.12.5-1.stretch_amd64.deb
ln -s /usr/local/lib/libwkhtmltox.so /usr/lib/libwkhtmltox.so

I dont love this solution as it requires custom configuration in a hard to customize container, so I can see this solution breaking with little to no recourse if Azure App Service decides that this is not ok. If someone else finds a better solution, I'd love to hear about it.

I can confirm that this solution works for now, thx Paul!

I was having this issue when updating from .net 6 to .net 8. Since this nuget was a branch off of DinkToPdf, I tried the DinkToPdf nuget version 1.0.8 instead and was able to run the application on a Linux agent using .net 8. I am using the standard azure linux agent for .net 8. I downloaded the libwkhtmlox.dll, libwkhtmltox.dlib, and libwkhtmltox.so libraries. Then added this to my .csproj to copy these over.

<ItemGroup>
  <!-- These libraries were copied from DinkToPdf nuget version 1.0.8 folder v0.12.4\64 bit.  -->

Are you using the standard dotnet azure app service images or did you roll out a custom dockerfile/image?

I am also facing this same error when migrating to .Net 8.0. Is there anyone found any Solution?

markandrewkato commented 2 months ago

I am able to run it in .NET8 containers with the following lines in dockerfile:

FROM mcr.microsoft.com/dotnet/aspnet:8.0 AS base

RUN apt-get update && ln -s /usr/lib/libgdiplus.so /lib/x86_64-linux-gnu/libgdiplus.so RUN apt-get install -y --no-install-recommends zlib1g fontconfig libfreetype6 libx11-6 libxext6 libxrender1 wget gdebi RUN wget https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.5/wkhtmltox_0.12.5-1.stretch_amd64.deb RUN wget http://archive.ubuntu.com/ubuntu/pool/main/o/openssl/libssl1.1_1.1.1f-1ubuntu2_amd64.deb RUN dpkg -i libssl1.1_1.1.1f-1ubuntu2_amd64.deb RUN gdebi --n wkhtmltox_0.12.5-1.stretch_amd64.deb RUN ln -s /usr/local/lib/libwkhtmltox.so /usr/lib/libwkhtmltox.so

But I am not happy for using libssl1.1 since it has vulnerabilities and caught as vulnerable by trivy container scanner, trying to find a solution.

Took me a long time but with some adjustments, I had this work on the sdk 8.0. Thanks!

Hi @colbroth where did you get the files, via ssh-ing into the linux app service, I don't see these 3 files to add to my own project. Can you pinpoint me in the right direction?

Currently I'm using the workaround of @PaulIvanov which is working fine, but takes a lot of time with new releases/restarting, because each time this library needs to be installed.

I got the files off of github DinkToPdf which is located at https://github.com/rdvojmoc/DinkToPdf/tree/master/v0.12.4/64%20bit

@colbroth Just be aware that using 7 years native binaries may have security risk implications.

DanTsion commented 1 month ago

hey @markandrewkato and @muraczewski, any update about this issue ? many people are starting their upgrade to .net 8 ... this issue will be trendy :/

HakanL commented 1 month ago

If someone can rebuild new binaries, using newer dependencies, then we can add them to this nuget package.

same problem with alpine

bashito commented 3 weeks ago

The solution @colbroth mentioned worked, but images and stylesheets that are in external files do not load. Anyone else facing similar issue?
