segfault cargo-pgx

[Guillaume444444]

Hi,
I am trying to use pgx in order build an extension in rust. I am facing a core dumped while executing following command:

cargo pgx run pg12

I've also tried with pg14, it does the same.
I've made no modification at all on the hello world project generated by "cargo pgx new".
The stack is here: stack.74049.txt
Best regards,
Guillaume

What OS is this? What kernel version? (uname -a please)

[Guillaume444444]

linux rh7 3.10.0-1160.66.1.el7.x86_64

[Hoverbear]

I assume that's like CentOS 7 and uses a super old GCC, you'll need to use GCC 7 or later. On CentOS you can do this:

yum install centos-release-scl
yum install devtoolset-7
scl enable devtoolset-7 bash

Maybe Red hat has similar.

[Guillaume444444]

Yes, RH7 has same packages. I've already installed them and it crashes. The stack file does not help?

[Hoverbear]

Hm, okay, looking at the stack:

This tells me you're segfaulting when it's generating the schema and looks nearly identical to #572, which should be fixed in #573, however we haven't cut that into a stable release yet. If you feel brave you can try 0.5.0-beta.0 (you need to directly specify this version in everything, as it's a beta. Eg cargo install cargo-pgx --version 0.5.0-beta.0.

[Hoverbear]

Since this is a duplicate of #572 , I'm closing it.

[Guillaume444444]

It works in version 0.5.0-beta.0.
Thank you.

[Hoverbear]

Glad it's working! We should have a stable release out soon. I'm kinda waiting for #592 to land. :)
