musl libc dlopen does not return in asterisk.

[Hervé Quillévéré at Home]

Hi all

musl libc dlopen does not return in asterisk.

Void linux musl libc arm (cubieboard2) on banana pi.
linux-4.12.8  sunxi_defconfig

asterisk-14.6.0
./configure
make
sudo make install
sudo make basic-pbx

run as root
asterisk -vvvc

This command should return with a prompt and
blocks in load_dynamic_module() in main/loader.c when calling dlopen().

As work has been done recently on dlopen, I tried with musl libc dowloaded
and compiled from git with the same result.

Replacing Void Linux musl with Void Linux glibc works.

Running Void Linux x86_64 musl and asterisk does not work and produce
the same effect.

Best Regards

Hi harvé

I  had a similar problem (did not yet have time to have a closer look)
when using musl-git with Asterisk 13.17. The following commit seemed to
have broken compatibility (at least for me): http://git.musl-libc.org/c
git/musl/commit/?id=6476b8135760659b25c93ff9308425ca98a9e777

Using the latest version of dynlink.c BEFORE this commit worked for me,
maybe it's worth a try? (1.1.16 had a different module loading issue
with my Asterisk installation that was fixed with
27b3fd68f67b674440d21ea7ca5cf918d2e1559f).

Best regards,

Pirmin
