Task
Task: curl

curl 8.16.0 is a command-line HTTP client.
Project link: curl.se

Task:
Compile and install curl to a specific location.

Difficulties:
Standard build, nothing special.

Environment:
Ubuntu 22.04 on amd64, without internet access.

Execution log
SYSTEM

You are a package-building specialist operating a Ubuntu 22.04 bash shell via one tool: run_terminal_cmd.
The current working directory of every run_terminal_cmd is /home/peter.
Execution rules:
- Always pass non-interactive flags for any command that could prompt (e.g., -y, --yes, DEBIAN_FRONTEND=noninteractive).
- Don't include any newlines in the command.
- The environment is offline, assume you have all the necessary tools already installed.
If you encounter any errors or issues while doing the user's request, you must fix them and continue the task.
At the end verify you did the user request correctly.

USER

You are given a curl v8.16.0 source code at /home/peter/curl.tar.gz. Please compile curl and install it to /home/peter/result. Create a symlink from /home/peter/result/curl to the actual binary. Make it build even if some third party dependencies are not available.

It seems that directly giving /usr as the prefix for --with-openssl is not working. Let's try compiling it without explicitly specifying OpenSSL, as it should be found in the default system paths if present.

It seems a TLS backend needs to be specified. Since we are trying to avoid dependencies, let's try to explicitly disable SSL.

It seems that even with --without-ssl, the build process is failing due to a missing ldap.h header. This is because the configure script still enabled LDAP. Let's disable LDAP as well.

I apologize, it seems like configure still enabled LDAP even after --without-ldap. I missed that it also enabled ldaps. Let's correct this and attempt to compile again.

Great! Curl has been compiled and installed. Now let's create a symlink to the binary.

compile-bench> ln -s /home/peter/result/bin/curl /home/peter/result/curl
[empty output]

The symlink has been created. Now let's verify everything.

compile-bench> ls -l /home/peter/result/curl
lrwxrwxrwx 1 peter peter 27 Sep 16 20:22 /home/peter/result/curl -> /home/peter/result/bin/curl

compile-bench> /home/peter/result/curl --version

The curl binary is present at /home/peter/result/bin/curl, the symlink /home/peter/result/curl points to it, and running curl --version confirms that the correct version (8.16.0) has been installed and is working as expected. All requested steps are successfully completed.

Task finished successfully, all checks passed!
Checks passed:
curl binary exists
curl version matches expected
curl downloaded the expected local file content
