Compiling pdftools in miniconda on Windows

[q8ing]

Hello,
I'm trying to run pdftools program on R in a miniconda environment on a Windows 10 64 bit operating system. However, I'm encountering an issue with the gcc linker. I'm not sure what to do. The rest of the programs work well, and I can compile them without any problems. pdftools is the only program I haven't been able to compile so far. Is there a solution to this problem?
The attached text file contains a significant portion of the error message.

I am grateful for any assistance and thank you.
