Build Dependencies

Tomocam requires the following dependencies:

CMake ≥ 3.20
C++ compiler with C++20 support (LLVM recommended)
OpenMP
Intel TBB (Threading Building Blocks)
FFTW3 (single and double precision)
libtiff
FINUFFT
CUDA (optional, for GPU acceleration)

Supported Platforms

Linux (tested on Arch Linux)
macOS (15.5+)

Building from Source

Linux (Arch)

cmake --preset arch
cmake --build --preset arch

macOS

cmake --preset macos
cmake --build --preset macos

Building with Tests

To enable tests during the build:

# Linux
cmake --preset arch -DENABLE_TESTS=ON
cmake --build --preset arch
ctest --preset arch

# macOS
cmake --preset macos -DENABLE_TESTS=ON
cmake --build --preset macos
ctest --preset macos

Installation

After building, install the library:

cmake --install . --prefix /path/to/install

This installs the binary and libraries to the specified prefix. Then set up your environment:

source setup.sh

which configures PATH and LD_LIBRARY_PATH for the installed layout.
