Novice here. I was able to build from source, but am getting a 
segmentation fault. Looks like it's an issue with my version of 
libssl-dev?

Software versions: Ubuntu Jammy, libgourou version : 0.7.1 (direct 
from repo)

Steps to reproduce the problem:

1. Install dependencies
> apt-get install -y build-essential libzip-dev libssl-dev 
libcurl4-gnutls-dev

> apt list | egrep "ssl-dev|zip-dev|curl4-gnutls-dev"
libcurl4-gnutls-dev/now 7.81.0-1ubuntu1.2 amd64 [installed,local]
libssl-dev/now 3.0.2-0ubuntu1.2 amd64 [installed,local]
libzip-dev/now 1.7.3-1ubuntu2 amd64 [installed,local]

2. clone repository + compile
> git clone git://soutade.fr/libgourou.git 
> cd libgourou
> make

3. move compiled lib + utils to /usr/local/, link
> cp libgourou.so         /usr/local/lib
> cp acsmdownloader /usr/local/bin 
> ldconfig
...

4. segmentation fault when running acsmdownloader
> acsmdownloader -f [acsm_file] -v

Similar failure with other adept utils. For example:
> adept_activate -a




Expected result:

> acsmdownloader --version
Current libgourou version : 0.7.1

> acsmdownloader -f [ACSMFILE] -v
