no, this is not about pylibacl, but just about libacl-2.3.1-6.fc38.x86_64, but i don't get libacl offered in the above menu. Issue is: there is no /usr/lib64/libacl.so in the package, but ld.so expects it. Running ldconfig does not help. Reproducible: Always Steps to Reproduce: 1. Try to compile and run the "program" main(){ acl_get_file(); } with gcc -o acl acl.c -lacl 2. Does not work. Linker complains /usr/bin/ld: cannot find -lacl: No such file or directory 3. Program is not built Actual Results: Program is not built Expected Results: program is built and can be run For 32 bit the file is there: % rpm -qf /lib/libacl.so.1 libacl-2.3.1-6.fc38.i686 % rpm -ql libacl.x86_64 /usr/lib/.build-id /usr/lib/.build-id/9a /usr/lib/.build-id/9a/4a1d4604fa70d1a77cdb27c3a3dc86616ed482 /usr/lib64/libacl.so.1 /usr/lib64/libacl.so.1.1.2301 In the Linker cache, there is libacl.so first: % strings /etc/ld.so.cache | grep libacl /lib64/libacl.so /lib/libacl.so.1 /lib64/libacl.so.1 There is a libacl.so.1 , but for whatever reason the linker does not use it. stracing the gcc ... shows, that it never tries to open any libacl.so.1 , only those without .1 Adding a symlink /lib64/libacl.so makes it work. This should be created by the package installation. Running ldconfig does not help.
libacl is a subpackage of the 'acl' package. Moving over there.
If you want to use (libacl) and use it in your programs, you have to install it: % dnf install libacl-devel
Ups, right. Sorry, i had only the 32 bit libacl-devel installed and did not watch closely enough.
