I managed to solve my problem. It was deep in libtools.m4. It turns out that they run $LD --help to scan it for "supported targets.*elf". My $LD had some flags baked in which prevented --help from outputting the correct message. This resulted in archive_cmds not being set, which made shared object linking impossible.

Thanks anyway.

Replying to my own question, as I've refined the test case.

This is the updated

Note that now the and are not expected to be generated. It seems that they were not generated with the previous makefile, there were just some symlinks created in .libs.

The is expected to be generated and installed into the lib directory, but it is not generated. The install target fails with this output:

libtool: install: /usr/bin/install -p .libs/ /home/srubenst/github/frida/build/frida-qnx-arm/lib/
/usr/bin/install: cannot stat '.libs/': No such file or directory

The full output with V=1 is available here:

Why is the not generated!?!

Please help me as I am tearing out my hair in frustration here.

Hi all,

I'm trying to build this ( Unfortunately, for some reason the file is not being generated. 

The and are being generated. The files are located in the .libs directory. There is a, but no .so.

Note that this same build file works as expected when building using a linux-arm toolchain, but fails when using a qnx-arm toolchain. I'm building on the same machine, so the only difference between the builds should be the toolchain bits themselves (gcc, ld, ar, nm, ...).

I've been struggling with this for a few days now, and I can't seem to get it to work.

I'd appreciate any insight or suggestions, as I don't really know how to proceed with this.
