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.

Defining the Build Path

I'm working on compiling curl with a bunch of features and a custom install location. I've decided on /home/peter/result as the install directory and will need to make a symlink. Next, I'll extract the source code to proceed with the build.

Formulating the Initial Steps

I've decided on the sequence of actions. First, I'll untar the source code. After that, it's time to install the build dependencies using apt. I have the exact commands in mind for the configure step. This is going smoothly!

compile-bench> tar -xzf curl.tar.gz

Planning Dependencies & Config

I've extracted the curl source code and am now focusing on the dependencies required for SSL/TLS v1.3, brotli, zlib, and zstd. I'm working to identify and install them, then I'll configure curl. It feels like a solid plan at this juncture.

Reviewing the Extracted Files

I've reviewed the extracted directory structure and am now cross-referencing it with a list of potential build dependencies. This is to confirm what libraries need to be installed before proceeding. Next step: pinpointing the exact versions required for seamless integration.

compile-bench> ls -F
curl-8.16.0/  curl.tar.gz

Analyzing Dependencies for Curl

I've successfully extracted the curl source code. My immediate focus is on gathering a complete list of dependencies. I'm starting with the common tools and libraries. Next, I will need to address specific requirements for features like TLS v1.3, brotli, zlib, and zstd support, which will require some research.

Defining the Installation Path

I've decided on /home/peter/result as the installation directory and will create a symbolic link to the curl binary within that location. The next step involves configuring the build process to enable the desired features.

Executing the Build Commands

I'm now in the curl-8.16.0 directory, ready to configure the build. I'll use the appropriate flags to include TLS v1.3, brotli, zlib, and zstd. After configuration, I will compile the source code, and install it into the /home/peter/result directory, as previously planned. Then, symlinking.

Resolving Build Issues

I've identified the root cause of the build failure: missing libpsl development libraries. My next step is installing the necessary packages (libpsl-dev) to resolve this dependency issue and allow the configure script to proceed successfully.

Attempting a Fix

I've now installed libpsl-dev because the configuration script was complaining about missing libpsl libraries. I'm going to re-run the configure command and see if this resolves the issue. Fingers crossed!

Analyzing Configuration Success

The configure script executed flawlessly after the libpsl-dev installation. I can see that SSL, brotli, zlib, and zstd are all enabled as expected. I'm moving to make and then make install next.

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'

Defining Build Configuration

I've successfully configured the build environment for curl, ensuring the required dependencies are met. I'm now focusing on crafting the specific ./configure command to enable SSL/TLS v1.3, brotli, zlib, and zstd support, along with setting the installation directory to /home/peter/result. The next step is to run that configuration command and verify its successful execution.

Creating the Symlink

I've confirmed that make install placed the curl binary in /home/peter/result/bin. Thus, I'm shifting gears to create a symbolic link. My plan is to establish a link from /home/peter/result/curl to the actual binary location, ensuring easy access to the compiled curl version.

Configuring the Build

I've successfully configured curl with the requested features: SSL, brotli, zlib, and zstd. I've also set the installation prefix, so the compiled program will reside in the custom directory as requested. Now, I'm ready to move on to the build process itself.

Verifying the Installation

I've just finished building and installing curl to the custom directory, /home/peter/result. I then created the symlink as requested. My next task is to confirm the installation by checking that curl is accessible, and that the symlink resolves correctly. After that, I'll verify the enabled features to ensure everything went as planned.

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

Analyzing Compilation Requirements

I'm currently focused on unpacking the user's request. They want to build curl from source, a task I've handled countless times. The critical aspects are the install location, the specific dependencies (SSL, Brotli, Zlib, Zstd), and the creation of a symbolic link. My immediate next step is to outline the exact shell commands for extraction.

Outlining Configuration Parameters

I'm now defining the ./configure command. The key is to use --prefix=/home/peter/result for the installation directory, and to include --with-ssl, --with-brotli, --with-zlib, and --with-zstd to enable the desired features. I've incorporated the lessons learned: installing libpsl-dev prevents a previous error. The exact syntax is top of mind.

Concluding the Build Process

The final verification step has confirmed the installation is successful. I've verified SSL, Brotli, Zlib, and Zstd are enabled, along with the expected version. The install location and symlink are correct. I'm satisfied with the outcome.

The curl v8.16.0 has been successfully compiled and installed to /home/peter/result with SSL (TLS v1.3), brotli, zlib, and zstd support. A symlink from /home/peter/result/curl to the actual binary has also been created.

Task finished successfully, all checks passed!
