Steps to reproduce:

1. Download and untar firefox-68.0.1.source.tar.xz
2. Use the following option to run ./mach build

#Set up the config options
export MOZCONFIG=`pwd`/mozconfig
cat > mozconfig << EOF

Expected results:

Build successfully. Note that my compile toolchain is in /home/linuxbrew/.linuxbrew where I have all the dependecies installed. The build system somehow still looks into /usr/lib for dependency, which shouldn't happen. I managed to build firefox 64.0 with the same setting.

Comment 1

[treinz]

The same error happens with firefox versions 67.0 and 66.0

Comment 2

[BugBot [:suhaib / :marco/ :calixte]]

Bugbug thinks this bug should belong to this component, but please revert this change in case of error.

Comment 3

[Nathan Froyd [:froydnj]]

You are trying to build with a too-old libstdc++. That's not going to work very well. Try using a newer libstdc++ by installing a newer version of GCC (6.x or better) on your system.

No, I am afraid you miss my point. I was using llvm 8 from linuxbrew (in /home/linuxbrew/.linuxbrew/bin/clang++ as shown above) and it ended up with the error

11:32.51 [style 0.0.1] /usr/lib/gcc/x86_64-redhat-linux/4.4.7/../../../../include/c++/4.4.7/new:91:7: note: previous declaration is here

which means the build system is looking at the wrong place for dependency -- it should only look into /home/linuxbrew/.linuxbrew/lib as llvm and clang was setup that way)
