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.

Beginning the Compilation

I've started by focusing on the initial steps. I'll begin by extracting the source code from the curl.tar.gz archive. This is my immediate task. I'm carefully reviewing the instructions to ensure I don't miss any crucial details during this extraction phase.

Formulating the Strategy

\n\n

I've finalized the basic approach. The extraction of source code is complete. Now, I'm shifting gears to identifying and installing all the necessary build dependencies. This is the next critical step, and I'm cross-referencing to ensure I have everything before configuration.

Navigating and Configuring

I've extracted the curl.tar.gz archive, which created the curl-8.16.0 directory. Now, I'm focused on navigating into this directory to set up the build configuration. I'll implement the required options for SSL/TLS v1.3 support and compression, then proceed with the compilation phase to get things installed.

Installing Dependencies and Options

I've entered the curl-8.16.0 directory and am preparing to configure the build. Before I proceed, I will install the dependencies for brotli, zlib, zstd, and SSL. Then, I will define the required configure options. Subsequently, I will proceed to compile and install it to /home/peter/result.

Considering the Build Steps

I've extracted the curl.tar.gz archive and installed those crucial dependencies: build-essential, libssl-dev, libbrotli-dev, libz-dev, and libzstd-dev. My next move is to delve into the extracted curl directory and begin configuring the build, followed by compilation.

Navigating Build & Installation

I've successfully configured the build options within the extracted directory. Now, the compilation phase is underway, which includes installing the built curl to my designated /home/peter/result directory. Following this, I plan to create the necessary symlink.

Identifying the Dependency

I've hit a snag; the configure script is complaining. Seems like it can't locate libpsl. I'm thinking I'll need to install the development package, specifically libpsl-dev, to resolve this. Fingers crossed!

Reattempting Configuration

I've addressed the missing libpsl dependencies by installing libpsl-dev. Now I must re-run the configure command from within the curl-8.16.0 directory to see if the configuration stage is successful this time.

Completing Installation Steps

I've successfully configured the project and have now moved on to the compilation phase using make. Once the build is complete, I'll execute the installation step. Finally, I'll address creating the necessary symlink.

Examining Build Configuration

I've successfully configured curl with the necessary features and the specified installation prefix. I'm now reviewing the generated configuration files to ensure everything is set up correctly, particularly the paths and dependencies, before starting the build process.

Installing the Package

I've built curl without issues. Now, I'm moving on to the installation phase, aiming to place it precisely where specified and create the symbolic link. Ensuring the symlink points correctly is the key next step, to avoid any pathing problems down the line.

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.

Initiating the Build

I've successfully extracted the curl archive and installed the required dependencies. Now, I'm preparing the configuration. I'll specify the installation directory as /home/peter/result and enable SSL, brotli, zlib, and zstd support during the build process.

Concluding the Setup

I've confirmed the installation path and location of the curl binary. My final step is generating the symbolic link. I'm creating it from /home/peter/result/curl to point to the installed binary at /home/peter/result/bin/curl. Then, I'm ready for the next phase.

Testing the Installation

I'm currently focused on verifying that the curl installation went smoothly. My plan is to execute the command that checks the installation, and then I will assess the output to confirm the presence of the features the user requested. I expect the command to be a readily available utility after the installation.

Assessing the Command

I'm now considering the specific command I'll run to validate the curl installation, and need to remember to include a check of the symlink. I need a command that proves the requested features, and confirms it is correctly installed. I believe I can easily identify one.

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

Planning the Curl Build

I'm now focused on the configuration options for the curl build. Specifically, I need to ensure that TLS v1.3, brotli, zlib, and zstd are enabled. I am considering the best way to determine which flags to use and the command execution order. The final symlink creation is now a lower priority.

Implementing the Configuration

I'm moving forward with implementing the configuration now. I'll use the configure command with the --prefix=/home/peter/result flag to specify the install directory. I'm adding flags to enable the desired features: --with-ssl, --with-brotli, --with-zlib, and --with-zstd. Also, I will disable shared libraries.

Adjusting for libpsl

I'm on track to get this going, even though I ran into a snag. The configure script is failing because of a missing libpsl-dev. I'm adding this to the dependency list and will re-run the configuration command now, incorporating the install of that missing package, to fix the build.

Validating the Outcome

I've just verified the installation and I'm satisfied with the build process now. The command /home/peter/result/curl -V successfully shows the correct version, the OpenSSL and compression support, and the installation path. Next, I will review everything.

Concluding the Build Process

I've reviewed the entire build process, and I am now confident in its successful completion. Every step, including the installation of all dependencies, configuration, compilation, installation, symlink creation, and verification, has been validated. The final verification confirms all the specified features were enabled.

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 enabled. A symlink from /home/peter/result/curl to the actual binary has also been created.

Verification:
```
