Instructions to Integrate Spire.Pdf on Ubuntu and g++

[dima_test_account]

Dear Support,

I am currently working on a project that requires the usage of the Spire.Pdf library in a C++ environment on Ubuntu 20.04.4 LTS. I have encountered some difficulties while attempting to integrate the library and would greatly appreciate your assistance.

The specifications of my environment are as follows:
Operating System: Ubuntu 20.04.4 LTS
Compiler: g++ (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0

Upon reviewing the available documentation, I noticed that there are only instructions provided for integrating Spire.Pdf into Windows Visual Studio, which unfortunately I cannot use on Ubuntu. Therefore, I kindly request guidance on how to integrate the Spire.Pdf library specifically for Ubuntu and the g++ compiler. Alternatively, if it is more suitable, I am open to using a different compiler.

I attempted to install the library independently, but I encountered issues and was unable to succeed. I have attached a sample project that I have been working on for reference.

When I tried to compile the project, I received the following error:

`g++ test.cpp -o test`
/usr/bin/ld: /tmp/ccDawKLo.o: in function `main':
test.cpp:(.text+0x20): undefined reference to `Spire::Pdf::PdfDocument::PdfDocument()'
/usr/bin/ld: test.cpp:(.text+0x37): undefined reference to `Spire::Pdf::PdfDocument::LoadFromFile(wchar_t const*)'
/usr/bin/ld: test.cpp:(.text+0x4f): undefined reference to `Spire::Pdf::PdfDocument::SaveToFile(wchar_t const*, Spire::Pdf::FileFormat)'
/usr/bin/ld: test.cpp:(.text+0x5b): undefined reference to `Spire::Pdf::PdfDocument::Close()'
collect2: error: ld returned 1 exit status

I attempted to address the issue by specifying the library link using the following command:

`g++ test.cpp -L./lib/x64/release -lSpire.Pdf.Cpp -o test`
/usr/bin/ld: cannot find -lSpire.Pdf.Cpp
collect2: error: ld returned 1 exit status

I apologize if I have overlooked any obvious steps or made any mistakes, as it has been some time since I last worked with C++. I would greatly appreciate any guidance or instructions you can provide to help me successfully integrate the Spire.Pdf library into my Ubuntu and g++ environment.

Thank you very much for your attention and assistance. I look forward to your prompt response.

Sincerely,
Dima
