Hello -
I’m building a cross-compiled gcc and binutils on Linux x86_64 for Solaris x86_64. The problem is that the executables produced hard-code the wrong path for the dynamic linker and get killed immediately upon launch. In elfxx-x86.c, the path for ELF64_DYNAMIC_INTERPRETER is defined as "/lib/ld64.so.1", but should be "/lib/amd64/ld.so.1" on a Solaris x86_64 system.
I came across this exact problem here:
https://binutils.sourceware.narkive.com/hNh1UFx2/building-a-cross-for-solaris-x86-target#post2
That thread is 15 years (!) old and implies this issue has beed addressed in the binutils 2.17/2.18 timeframe. I’m building binutils 2.32 and still hitting this same problem.
What’s the fix?
Thanks.
- Paul

1. Please get binutils 2.38.
2. Configure binutils 2.38 to target Solaris/x86-64.

OK, I did. Same result.

Specifically, I did:
configure --enable-gold=default --disable-ld --enable-lto --prefix=/solaris-x86_64 --disable-multilib --disable-nls --target=x86_64-sunos-solaris2.11 --with-sysroot=/solaris-x86_64 --disable-werror --enable-plugins
which is what I’ve been doing.
Assuming that you didn’t make a typo when you typed "x86-64” (with a dash, not an underscore), I also tried:
--target=x86-64-sunos-solaris2.11
but then the target triple parser presumably gets confused and complains:
Kernel `sunos' not known to work with OS `solaris2.11’
Looking at the binutils source code, the literal string "/lib/ld64.so.1” still occurs and the literal string "/lib/amd64/ld.so.1” still doesn’t.

Gold doesn't support Solaris.
