Building static library on CentOS

[Yifei Bao]

Hi,

I'm trying to build a static library of PDFium on LInux for another project, but when I link it there's a ton of link errors. 

snapshot of the errors:

My gn args are:

is_component_build = false

pdf_is_complete_lib = true

pdf_enable_v8 = false

pdf_is_standalone = true

Anyone knows how to solve the issue? Thanks.

Your build/ dir, sysroot, and/or libc++ is broken in some way. Since
this is only happening in your copy of PDFium, I don't think others
will likely be able to track down the exact problem for you.

Is it possible that I'm missing build dependencies because the `./build/install-build-deps.sh` does not support CentOS?

[Lei Zhang]

It's hard to say. If you build with Ninja, add -d keeprsp so the .rsp
files used in the linking process do not get deleted. If you look in
the .rsp files, do they contain entries for files in
obj/buildtools/third_party/libc++/libc++*?

Yes, all the libraries are in the nasm.rsp but not in the libpdfium.a.rsp.
