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.

Inspecting tarball contents

I’m thinking about how to inspect the top-level directory of a tarball. I want to capture the output, but it seems I can’t parse it through the tool. I can run a command instead, and the tool returns JSON, which will help us decide the next steps. Alternatively, I could use a shell variable to capture the directory name, but variables can’t be preserved across different runs. I guess I could combine everything into a single command execution.Compiling in the shell

I'm considering how the environment's shell will maintain variables within a single command. That's good! I'll also compile with -j$(nproc) to enable concurrency by utilizing the number of cores. I want to create a robust command. I can use set -e to stop on errors, but I need to be cautious not to include newlines. I have to remember that if a command fails and stops the chain, I’ll need to troubleshoot and continue adjusting accordingly.Planning tar command sequence

Alright, I’m mapping out my steps. First, I’ll run the command tar -tzf curl.tar.gz | head -n 1 to identify the directory, which I expect to be “curl-8.16.0/.” It's good to confirm it, though. I can set the directory name as a variable for later use. I could also use a single-run script to streamline the process, where I extract and configure everything in one go. However, I have to keep in mind to ensure the build can still proceed even if some third-party dependencies aren’t available.Configuring cURL options

I’m thinking of proposing the command ./configure with multiple flags to disable various components and set a prefix. However, the more I disable, the greater the chance that the configuration will fail due to unknown flags. So, I should verify whether these options are accepted by cURL. Common options I recall include --with-ssl=, and yes, --without-ssl is typically accepted. Still, I need to be cautious and choose only the minimal flags that are reliably supported to avoid any configuration errors.Checking cURL options for configuration

I'm reviewing the known options for configuring cURL 8.16.0. I see that for TLS backends, I can use flags like --with-openssl, and for disabling certain features, it’s usually okay to apply flags like --without-ssl. I want to ensure that the options I use are supported to avoid configuration failures. I can propose using a minimal set: ./configure --prefix=/home/peter/result --without-ssl --disable-ldap --disable-ldaps to minimize dependencies. I’ll also remember to check the top-level directory name next!

Evaluating cURL configuration settings

I’m considering cURL's configuration default behavior, which commonly uses libpsl if it's available. If it's not present, it typically doesn’t throw an error, it just disables it. The phrase “where specified” appears when using options like --with-libpsl. It seems that cURL defaults to trying “yes” to find the library, which could cause an error if the libraries aren’t installed. To avoid this issue, I think we should pass --without-libpsl if it’s not found. This likely applies to other libraries too.Fixing cURL configuration

I see that the message indicates it’s “where specified,” but it’s unclear. Maybe the configure process for IDN detection defaults to --with-libidn2 being ‘no’. If I pass --enable-alt-svc, that might change things. Anyway, I need to fix this by adding --without-libpsl to the configuration. I’ll re-run the configure and build process, using the command: rm -rf curl-8.16.0 && tar -xzf ... && cd ... && ./configure ... --without-libpsl. Let's get started on that!

I'm making sure that we didn't need any man pages or documents requiring Python or Perl. It looks like we found some Perl functionality, but thankfully we won't need anything extra. So, I'll go ahead and wrap things up. It's always nice when things come together without too much fuss! Now, let’s produce the final output.

Done.

What I did:
- Unpacked /home/peter/curl.tar.gz and built curl 8.16.0 with options to avoid failing on missing third-party libraries.
- Configured with:
- --prefix=/home/peter/result
- --without-ssl
- --disable-ldap
- --disable-ldaps
- --without-libpsl
- Built and installed, then created the symlink: /home/peter/result/curl -> /home/peter/result/bin/curl

Verification:
- /home/peter/result/bin/curl --version output:
curl 8.16.0 (x86_64-pc-linux-gnu) libcurl/8.16.0
Protocols: dict file ftp gopher http imap ipfs ipns mqtt pop3 rtsp smtp telnet tftp ws
Features: alt-svc AsynchDNS IPv6 Largefile threadsafe UnixSockets
- Symlink exists:
lrwxrwxrwx ... /home/peter/result/curl -> /home/peter/result/bin/curl

You can run curl via /home/peter/result/curl or /home/peter/result/bin/curl.
