chromium-x11: Found local symbols on part of the global table

[ahcbb6]

Hello, While I'm not entirely sure this is a bug (since I figured you would have run into this already), I am wondering if anyone has run into this problem:

My initial guess was that my toolchain might be too old, but I have already upgraded it with no luck.

Thanks in advance. Alejandro

Hi, what distro are you building this on? The errors come from a binary that is built and linked on the host, so I'm still not sure if that's because your host toolchain is too old or too new actually.

[ahcbb6]

Hey Raphael,

I'm building on Ubuntu 16.04 (xenial), which should be too old.

I initially tried simply installing a newer toolchain through the Ubuntu Toolchain PPA: https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/test but proved unsuccessful (tried gcc 9)

Since I still believed that some part of the toolchain would be too old, and actually my goal is to come up with a solution to build chromium on older systems, I built my own toolchain through Yocto/OE and automatically used that one as it was coming from the host, so GCC 9.2.0 and Binutils 2.31, Glibc 2.30.

To be honest its still unclear to me why the host toolchain is "contaminating" the build, shouldn't everything be built with the cross toolchain?, I dont have a lot of history with the meta-browser layer, so perhaps if I understood better the reason why a certain host toolchain (or certains parts of it) are required I would be able to help in some way.

So is part of the host toolchain being used throughout the build?, or does the clang/llvm toolchain built with an older host toolchain behaves/generate different results than one built with a newer toolchain?

Or also if you can point me to some documentation/code to take a look at to understand this better that would help a lot.

Thanks! Alejandro

perhaps disable using lld linker on host. If you have ld-is-lld DISTRO_FEATURES then reset it.

or meta-clang has a bbappend which enforces lld perhaps comment that out

dynamic-layers/browser-layer/recipes-browser/chromium-x11_%.bbappend

GN_ARGS += "use_lld=true use_gold=false"

[ahcbb6]

Hey Khem, I had already tried changing the DISTRO_FEATURES, I did not see that meta-clang was enforcing that, I'm gonna give that a try now.

Alejandro

[ahcbb6]

Hey guys, I was able to build now, commenting that line on meta-clang fixed my linking issue.

Still, I'd like to understand what part(s) of the Host toolchain are required to be in a certain version?, it is just GCC and libstdc++?, binutils as well? anything besides that?

Thanks

I have the same problem, it is still not fixed.
