CMake can't find OpenSSL, but it's installed (Arch Linux)

Hi everyone,

I'm having trouble building a project (specifically, a Rust crate that depends on libgit2) on Arch Linux. CMake is complaining that it can't find OpenSSL, even though OpenSSL is definitely installed on my system.

Here's the error message I'm getting from CMake:

-- Could NOT find GSSAPI (missing: GSSAPI_LIBRARIES) 
-- Could NOT find OpenSSL, try to set the path to OpenSSL root folder in the system variable OPENSSL_ROOT_DIR (missing: OPENSSL_CRYPTO_LIBRARY) (found version "3.4.0")
CMake Error at cmake/SelectHTTPSBackend.cmake:29 (message):
  Unable to autodetect a usable HTTPS backend.Please pass the backend name
  explicitly (-DUSE_HTTPS=backend)
Call Stack (most recent call first):
  src/CMakeLists.txt:40 (include)

I've already tried the following:

Reinstalling OpenSSL: I've reinstalled the openssl package using

sudo pacman -S openssl

Verifying Installation: I can confirm that the OpenSSL libraries (libssl.so and libcrypto.so) exist in /usr/lib and /usr/lib64.
pkg-config:

pkg-config --cflags --libs openssl

outputs

-lssl -lcrypto

so pkg-config seems to be configured correctly.
cmake command:

cmake lib/libgit2-1.7.0 -Blib/build -DBUILD_SHARED_LIBS=OFF -DLINK_WITH_STATIC_LIBRARIES=ON

also tried:               

cmake lib/libgit2-1.7.0 -Blib/build -DBUILD_SHARED_LIBS=OFF -DLINK_WITH_STATIC_LIBRARIES=ON -DOPENSSL_CRYPTO_LIBRARY=/usr/lib/ -DOPENSSL_ROOT_DIR=/usr/local

Could anyone offer some guidance on how to resolve this?  Any help would be greatly appreciated!

Thanks in advance.

Usually for compiling you need the devel or dev packages. I'm new to Arch so not yet 100% on the naming schemes. Look for openssl-devel or similar.

Cmake told you that it found version 3.4.0.
Which one does the package need?

Re: CMake can't find OpenSSL, but it's installed (Arch Linux)

It looks like not-finding openssl is NOT the issue.

CMake Error at cmake/SelectHTTPSBackend.cmake:29 (message):
  Unable to autodetect a usable HTTPS backend.Please pass the backend name
  explicitly (-DUSE_HTTPS=backend)
Call Stack (most recent call first):
  src/CMakeLists.txt:40 (include)

Please post the exact build command used and the full commandline output it gives.

A link to to the project files, especially to src/CMakeLists.txt would also help .

Moderator Note
This is not an installation topic, but until more is known about the project I can't determine which subboard it should be in.
For now it can stay in installation .

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?

Re: CMake can't find OpenSSL, but it's installed (Arch Linux)

Thanks you all very much for replies! I updated libgit2 to the latest version, and the behavior has changed only slightly. When I ran the command:

cmake lib/libgit2 -Blib/build -DBUILD_SHARED_LIBS=OFF -DLINK_WITH_STATIC_LIBRARIES=ON

I received the following output:

CMake Deprecation Warning at CMakeLists.txt:7 (cmake_minimum_required):
  Compatibility with CMake < 3.10 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
  to tell CMake that the project requires at least <min> but has been updated
  to work with policies introduced by <max> or earlier.

It still can't find openssl, but it found `mbedtls`, by the way it can't build anyway with cmake --build lib/build command:

Cmake successfully found openssl:

-- Found OpenSSL: /usr/lib/libcrypto.so (found version "3.4.1")

And successfully built library. But then I try to link to that library from rust and get these errors:

warning: `git-toy` (bin "git-toy") generated 5 warnings
error: could not compile `git-toy` (bin "git-toy") due to 1 previous error; 5 warnings emitted

Maybe that is because I setted up

-DOPENSSL_CRYPTO_LIBRARY=/usr/lib/libcrypto.so -DOPENSSL_SSL_LIBRARY=/usr/lib/libssl.so 

manually? Now rust can't find openssl too.

That strange, because pkg-config shows that these libs are available:

$ pkg-config --libs libssl libcrypto
-lssl -lcrypto

Re: CMake can't find OpenSSL, but it's installed (Arch Linux)

Please use [code][/code] tags. Edit your post in this regard.

And what objects is that mold command (trying to) link in?
Why is mbedtls installed and why are you not building https://aur.archlinux.org/packages/libgit2-git ?

Re: CMake can't find OpenSSL, but it's installed (Arch Linux)

The mold linker is trying to combine the compiled libgit2 library with my rust project. The linking process fails because the compiled libgit2 library has calls to functions inside of the openssl libraries, and the linker can't find those openssl functions.

mbedTLS is installed on my system as a dependency of obs-studio package. I'm not explicitly installing it for libgit2; it's likely a system-wide dependency.

I'm attempting to build libgit2 from source within my Rust project's crates/git-toy-sys/lib/libgit2 directory because it is a dependency of my rust crate. I was not aware of the aur package, but I am attempting to build the library from source because it is a dependency of my crate. I'm trying to keep the build process contained within my Rust project's workspace

The mold linker is trying to…

Please don't paraphrase, https://bbs.archlinux.org/viewtopic.php?id=57855

Because

the linker can't find those openssl functions.

Yes, but what objects are actually being linked in here?

I'm not explicitly installing it for libgit2

So why

In file included from /home/george/dev/rust/projects/git-toy/crates/git-toy-sys/lib/libgit2/deps/ntlmclient/crypt_mbedtls.h:12,
                 from /home/george/dev/rust/projects/git-toy/crates/git-toy-sys/lib/libgit2/deps/ntlmclient/crypt.h:18,
                 from /home/george/dev/rust/projects/git-toy/crates/git-toy-sys/lib/libgit2/deps/ntlmclient/ntlm.h:14,
                 from /home/george/dev/rust/projects/git-toy/crates/git-toy-sys/lib/libgit2/deps/ntlmclient/ntlm.c:19:

does libgit2 inclde it?
Afaikt it's not a dependency of the AUR package.

Build that first, see how it goes, have a look at its PKGBUILD and what's different from your current setup.

Moving to Programming subboard as that seems most appropriate

Re: CMake can't find OpenSSL, but it's installed (Arch Linux)

Didn't see the part where you made sure you have the dev versions of these libraries installed.

Note that dev versions of libraries usually come with/from different packages.

(Interesting, this is one part where Arch Linux differs from other distros. There's no dev packages on Arch Linux :] )
