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.

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.

I built curl 8.16.0 from /home/peter/curl.tar.gz with SSL (OpenSSL/TLS 1.3), brotli, zlib, and zstd, and installed it to /home/peter/result with the requested symlink.

What I did:
- Extracted the source
- Installed required build dependencies (non-interactively): build-essential, autoconf, automake, libtool, pkg-config, ca-certificates, libssl-dev, libzstd-dev, libbrotli-dev, zlib1g-dev, libpsl-dev
- Configured curl with: --prefix=/home/peter/result --with-ssl --with-brotli --with-zlib --with-zstd
- Built and installed
- Created symlink /home/peter/result/curl -> /home/peter/result/bin/curl

Verification:
- Binary present and symlink created:
- [ -x /home/peter/result/bin/curl ] and [ -L /home/peter/result/curl ] => OK
- Feature check:
- LD_LIBRARY_PATH=/home/peter/result/lib /home/peter/result/bin/curl --version
- Output shows: OpenSSL/3.0.2, zlib/1.2.11, brotli/1.0.9, zstd/1.4.8, libpsl/0.21.0
- Features include: SSL, brotli, libz, zstd
- TLS v1.3 capability:
- Using OpenSSL 3.0.2, which supports TLS 1.3

Paths:
- Install prefix: /home/peter/result
- Binary: /home/peter/result/bin/curl
- Symlink: /home/peter/result/curl

If you want curl to run without specifying LD_LIBRARY_PATH when using the non-system libcurl at /home/peter/result/lib, you can add that directory to LD_LIBRARY_PATH in your shell environment or set an rpath when linking other binaries against this libcurl.

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
curl gzip compression test passed
curl version shows zstd support
