Introduction

In this article, we will discuss an installation issue with the grss package using source code. The issue arises when following the instructions provided in the Install via source code (Python) section of the grss documentation. We will explore the error messages, provide a step-by-step guide to reproduce the issue, and offer potential solutions to resolve the problem.

Error Messages

The error messages are as follows:

Traceback (most recent call last):
    File "/home/athul/Documents/grss/.venv/bin/pybind11-config", line 5, in <module>
      from pybind11.__main__ import main
    ModuleNotFoundError: No module named 'pybind11'

Consolidate compiler generated dependencies of target apophis
      make[2]: *** No rule to make target '../extern/cspice/lib/cspice.a', needed by '../tests/cpp/prop/apophis.out'.  Stop.
      make[1]: *** [CMakeFiles/Makefile2:176: tests/cpp/prop/CMakeFiles/apophis.dir/all] Error 2
      make: *** [Makefile:91: all] Error 2

Steps to Reproduce

To reproduce the issue, follow these steps:

Clone the grss repository using the following command:

$ git clone https://www.github.com/rahil-makadia/grss

2. Navigate to the `grss` directory:
   ```bash
$ cd grss

Run the initialize.sh script:

$ source initialize.sh

4. Create a Python 3.12 virtual environment:
   ```bash
<created a Python 3.12 venv>

Install the grss package using pip:

$ python3 -m pip install .


**Diagnostic Information**
-------------------------

The diagnostic information is as follows:

* System: Linux
* Release: 6.8.0-52-generic
* Version: #53~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Wed Jan 15 19:18:46 UTC 2023
* Machine: x86_64
* Processor: x86_64
* Platform: linux
* Python Version: 3.12.9 (main, Feb 5 2025, 08:49:00) [GCC 11.4.0]
* CMake Version: 3.22.1
* Pybind11 Version: 2.13.6

**Potential Solutions**
-----------------------

Based on the error messages and diagnostic information, the following potential solutions can be considered:

1.  **Verify Pybind11 Installation**: Ensure that Pybind11 is installed correctly. You can verify this by running the following command:
    ```bash
$ pip show pybind11

If Pybind11 is not installed, install it using pip:
```bash

$ pip install pybind11

2.  **Check CMake Version**: Ensure that CMake is installed and up-to-date. You can check the CMake version by running the following command:
    ```bash
$ cmake --version

If CMake is not installed or outdated, install the latest version.

Verify CMake Configuration: Ensure that CMake is configured correctly. You can check the CMake configuration by running the following command:

$ cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_COMPILER=g++-12 -DCMAKE_C_COMPILER=gcc-12 ..

    If the CMake configuration is incorrect, adjust the configuration as needed.
4.  **Check for Missing Dependencies**: Ensure that all dependencies required by the `grss` package are installed. You can check the dependencies by running the following command:
    ```bash
$ pip install -r requirements.txt

If any dependencies are missing, install them using pip.

Rebuild the Package: If none of the above solutions work, try rebuilding the grss package from scratch. This may involve deleting the build directory and running the cmake and make commands again.

Q: What is the installation issue with the `grss` package using source code?

A: The installation issue arises when following the instructions provided in the Install via source code (Python) section of the grss documentation. The error messages indicate that there is a problem with the pybind11 installation and a missing dependency for the cspice library.

Q: What are the error messages indicating?

A: The error messages are indicating that there is a problem with the pybind11 installation, as it is not found in the Python environment. Additionally, the make command is failing due to a missing dependency for the cspice library.

Q: How can I verify if Pybind11 is installed correctly?

A: You can verify if Pybind11 is installed correctly by running the following command:

$ pip show pybind11

If Pybind11 is not installed, you can install it using pip:

$ pip install pybind11

Q: What is the CMake configuration, and how can I check it?

A: CMake is a build system generator that creates a build system for your project. The CMake configuration is used to specify the build settings, such as the compiler, build type, and dependencies. You can check the CMake configuration by running the following command:

$ cmake --version

This will display the version of CMake installed on your system.

Q: How can I check for missing dependencies?

A: You can check for missing dependencies by running the following command:

$ pip install -r requirements.txt

This will install all the dependencies specified in the requirements.txt file.

Q: What is the `build` directory, and why is it important?

A: The build directory is where CMake generates the build files for your project. If you delete the build directory, you will need to run the cmake and make commands again to rebuild the project.

Q: How can I rebuild the `grss` package from scratch?

A: To rebuild the grss package from scratch, you can delete the build directory and run the following commands:

$ cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_COMPILER=g++-12 -DCMAKE_C_COMPILER=gcc-12 ..
$ make

This will rebuild the grss package from scratch.

Q: What are some common issues that can cause installation problems?

A: Some common issues that can cause installation problems include:

Missing dependencies
Incorrect CMake configuration
Missing or incorrect Python environment
Outdated or missing build tools (e.g., CMake, make)

Q: How can I troubleshoot installation problems?

A: To troubleshoot installation problems, you can try the following steps:

Check the error messages for clues about the problem
Verify that all dependencies are installed correctly
Check the CMake configuration to ensure that it is correct
Try rebuilding the package from scratch

By following these steps and considering the potential solutions, you should be able to resolve the installation issue with the grss package using source code.
