dnf install fmt. It was successful. But when I try to use it as
#include <fmt/format.h> it says it is not found. I downloaded
include from fmt git page so it finds
format.h now with
-I... but I have compilation errors.
undefined reference to `fmt::v8::vformat[abi:cxx11](fmt::v8::basic_string_view<char>, fmt::v8::basic_format_args<fmt::v8::basic_format_context<fmt::v8::appender, char> >)'
collect2: error: ld returned 1 exit status
-lfmt but it errors with
/usr/bin/ld: cannot find -lfmt
I cant find any help for this type of use on the git.
How do you use
fmt lib on CentOS9 without building
fmt project manually?
EIDT: dnf install output
Fedora/RHEL/CentOS uses the following naming convention for all packages that installed shared libraries:
name – this package contains runtime shared libraries that are needed to run programs that are linked with this library.
-devel – the “devel” packages contains header files and the symbolic links that allow you to link with the shared library when developing applications that use this library.
You need both packages to compile the code that uses the library. The
devel package specifies a dependency on the main package, so
dnf install name-devel is going to install both packages.
You should invest a little bit of time to learn how to build your own
rpm packages. It’s not that complicated. When you build your package
rpmbuild will take care of analyzing the resulting binary, discovering which shared libraries it links with, then recording the appropriate dependency in your own
rpm package, so installing it will pull in only the main
