compile in mips CPu

[19940610mxh666]

Hi, I want to compile pdfium under MIPS platform. What changes do I need to make? Thanks .

Hi @19940610mxh666,

I don't known. You should address your questions to the pdfium community.

BTW, which MIPS processor are you targeting?

Best regards, Benoit

PDFium Bug 1626 seems to suggest that it's possible somehow?

Thank you for your reply. The processors I use are 龙芯3A4000(mips)，龙芯3A3000(mips) and 龙芯3A5000(longarch).

gn help target_cpu lists the following:

Possible values

  - "x86"
  - "x64"
  - "arm"
  - "arm64"
  - "mipsel"
  - "mips64el"
  - "s390x"
  - "ppc64"
  - "riscv32"
  - "riscv64"
  - "e2k"
  - "loong64"

So I suppose the 3A3000 and 3A4000 will be mips64el and the 3A5000 loong64. But presumably just setting target_cpu in the GN configuration won't be sufficient and additional configuration / dependencies might be needed for cross-compilation?

Thank you very much for your tips. I will do some tests according to these tips.

@19940610mxh666 Did you succeed? If so, which steps did you use, and do you think it would be possible to add here?
