Building cross-compiler for x86_64-sun-solaris fails due to jemalloc error.

[jcoughlin9]

I am trying to build Rust 1.17.0 to cross compile to x86_64-sun-solaris and am running into an error similar to #15228. I am running on a CentOS 7 host with the default g++, v4.8.5.

Configuring with the following commands:

git clone https://github.com/rust-lang/rust.git
cd rust
git checkout 56124baa9e73f28c0709e59e74783cf234a978cf    # Rust 1.17.0
./configure --target=x86_64-sun-solaris
./x.py build --target x86_64-sun-solaris

Produces the error:

checking whether utrace(2) is compilable... no
checking whether valgrind is compilable... no
checking whether a program using __builtin_ffsl is compilable... no
checking whether a program using ffsl is compilable... no

Am I doing something wrong? Or does the issue with jemalloc still exist for x86_64-sun-solaris?

I would just try building without jemalloc, ./configure --disable-jemalloc should do the trick, I think.

That works, thanks.
