Hi! I’m Alex, an undergraduate from Romania. I am currently familiarizing myself with the reltrans codebase. I have viewed the proposed projects as part of GSoC 2026 and i am considering them. I do have to admit that it is harder than expected to set up reltrans. Running `make` prompts me to missing dependencies even though i followed the documentation guide for installation. I already configured and compiled a full HEASOFT package and located fourier transform `fftw3.f03` file. I really don’t know what i have done wrong and i would appreciate guidance. Thanks! ```auto make gfortran -DHAVE_INLINE -fPIC -fno-automatic -fno-second-underscore -fno-omit-frame-pointer -fopenmp -Ibuild/include -I/include -I/include/fftw -Jbuild/cache -Ibuild/cache -O3 -shared -export-dynamic -c wrappers.f90 -o build/cache/wrappers.o f951: Warning: Nonexistent include directory ‘/include’ [-Wmissing-include-dirs] f951: Warning: Nonexistent include directory ‘/include/fftw’ [-Wmissing-include-dirs] f951: Warning: Flag ‘-fno-automatic’ overwrites ‘-frecursive’ implied by ‘-fopenmp’ subroutines/amodules.f90:79:0: 79 | include 'fftw3.f03' | Fatal Error: Cannot open included file ‘fftw3.f03’ compilation terminated. make: *** [Makefile:101: build/cache/wrappers.o] Error 1 ``` ---

Hi Alex, I’m also facing the same issue while setting up reltrans. Even after configuring HEASOFT and locating the `fftw3.f03` file, the build still fails with the same missing include error. Following this thread in case there’s something we’re overlooking. Thanks for raising it!
