New submission from Michael Felt: I was asked to assist with some problems with a "pip install numpy" and - maybe I am barking up the wrong tree. However, in the thread https://github.com/numpy/numpy/issues/8118
in short, if "python" is responsible for providing the -D flags "extensions" receive during the pip build process - the -D_LARGE_FILES also needs to be provided for AIX. DETAILS... you can see the complete command "pip build|install" reports as creating an error at the URL above - here is the critical part. xlc_r -I/opt/include -O2 -qmaxmem=-1 -qarch=pwr5 -q64 -I/opt/buildaix/includes -DNDEBUG -DHAVE_NPY_CONFIG_H=1 -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE=1 -D_LARGEFILE64_SOURCE=1 ... The key error is several of this form: "/usr/include/unistd.h", line 921.25: 1506-343 (S) Redeclaration of fclear64 differs from previous declaration on line 918 of "/usr/include/unistd.h".
