I would like to ask how you compile pdfium. The chromium6307 version of pdfium I compiled will crash when using FPDF_InitLibrary on windows7 system, but this problem will not occur when using the one you provide
I use the command line to compile, enter the command line as follows:
gn args out/x64
ninja -C out/x64 pdfium

My args.gn file looks like this:
is_component_build = false
is_debug = false
pdf_enable_v8 = false
pdf_enable_xfa = false
pdf_is_standalone = true
target_cpu = "x86"
target_os = "win"
treat_warnings_as_errors = false

Now I can't find the problem, I hope to get your reply, thank you
