Task
Task: curl-ssl

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

Task:
Compile and install curl to a specific location. Build with SSL support (TLS v1.3), brotli, zlib and zstd.

Difficulties:
Installing dependencies can be tricky.

Environment:
Ubuntu 22.04 on amd64, with 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.
- You can use sudo.
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 sure it builds with SSL support (TLS v1.3), brotli, zlib and zstd.

ASSISTANT
Show reasoning

The user wants me to compile curl from the source code at /home/peter/curl.tar.gz, version 8.16.0. Install it to /home/peter/result. Create a symlink from /home/peter/result/curl to the binary. It needs SSL support (TLS v1.3), brotli, zlib, zstd.

Compiling curl from source
- The user wants to compile curl from /home/peter/curl.tar.gz, version 8.16.0, and install it to /home/peter/result.
- They need SSL support for TLS v1.3, plus brotli, zlib, and zstd compression.

Setting up installation
- A symlink will be created from /home/peter/result/curl to the compiled binary for easy access.
- The process involves configuring and building curl with the specified dependencies and version.

Setting up installation
- Extract curl.tar.

compile-bench> cd /home/peter && tar -xzf curl.tar.gz
[empty output]
ASSISTANT

Extraction succeeded without error, empty output is fine, just unpacking.

compile-bench> cd /home/peter/curl-8.16.0 && sudo DEBIAN_FRONTEND=noninteractive apt update && sudo DEBIAN_FRONTEND=noninteractive apt install -y build-essential libssl-dev zlib1g-dev libzstd-dev libbrotli-dev pkg-config

The configure failed because libpsl is not found. libpsl is for Public Suffix List, used for cookie domain handling.

Troubleshooting build issue
- The configuration failed because libpsl, required for Public Suffix List and cookie domain handling, is missing.
- This is needed to build curl, and Ubuntu typically provides it through the libpsl-dev package.
- The error message indicates a configure step failure, pointing to the missing library.

Libraries have been installed in:
   /home/peter/result/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the '-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the 'LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the 'LD_RUN_PATH' environment variable
     during linking
   - use the '-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to '/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

Perfect! It shows curl 8.16.0 with the features: OpenSSL/3.0.2 (which supports TLS 1.3), zlib/1.2.11 brotli/1.0.9 zstd/1.4.8

Everything looks good! I have successfully compiled and installed curl v8.16.0 to /home/peter/result with the required features.

Summary of Actions Taken:
1. Extracted the source: Untarred curl.tar.gz from /home/peter to /home/peter/curl-8.16.0.
2. Installed dependencies: Used apt to install essential build tools and libraries including build-essential, libssl-dev for SSL/TLS (OpenSSL supports TLS v1.3), zlib1g-dev for zlib, libbrotli-dev for brotli, libzstd-dev for zstd, libpsl-dev for PSL support, and pkg-config.
3. Configured the build: Ran ./configure --prefix=/home/peter/result --with-ssl --with-brotli --with-zstd to enable SSL, brotli, and zstd support.
4. Compiled the code: Built with make -j$(nproc) for parallel compilation.
5. Installed the components: Used make install to place binaries and libraries in /home/peter/result.
6. Created the symlink: Linked /home/peter/result/curl to /home/peter/result/bin/curl for easy access to the binary.

Verification:
- The curl binary is located at /home/peter/result/bin/curl.
- Running $LD_LIBRARY_PATH=/home/peter/result/lib:$LD_LIBRARY_PATH /home/peter/result/curl --version confirms:
- Version: 8.16.0
- SSL support with OpenSSL 3.0.2 (includes TLS v1.3)
- Enabled features: brotli, zstd, SSL, zlib
- Full output includes protocols and features as expected.

The installation supports all requested features, and the symlink points to the correct binary. The build was successful with no errors.

Task finished successfully, all checks passed!
Checks passed:
curl binary exists
curl version matches expected
curl downloaded the expected local file content
curl HTTPS request to google.com returned content-type: text/html
curl TLSv1.2 connection to google.com used TLSv1.2
curl TLSv1.3 connection to google.com used TLSv1.3
curl brotli compression test passed
