This particular version is from the sage-on-gentoo overlay. That being said I don't think this stuff is specific to it. The only extra thing I have is an upstream patch that is pure python. I'd like to remind the original poster to attach build logs. I have such message in my own logs. This is during the configuration phase, nothing particular happening there, numpy is trying to figure the properties of the compiler and linker like a configure script would. A more complete relevant bit of log is ########### compile options: '-Inumpy/core/src/private -Inumpy/core/src -Inumpy/core -Inumpy/core/src/npymath -Inumpy/core/src/multiarray -Inumpy/core/src/umath -Inumpy/core/src/npys$ x86_64-pc-linux-gnu-gcc: _configtest.c _configtest.c:1:5: warning: conflicting types for built-in function ‘exp’ [-Wbuiltin-declaration-mismatch] int exp (void); ^~~ x86_64-pc-linux-gnu-gcc -march=native -O2 -pipe _configtest.o -o _configtest _configtest.o: In function `main': _configtest.c:(.text.startup+0x5): undefined reference to `exp' collect2: error: ld returned 1 exit status _configtest.o: In function `main': _configtest.c:(.text.startup+0x5): undefined reference to `exp' collect2: error: ld returned 1 exit status failure. removing: _configtest.c _configtest.o C compiler: x86_64-pc-linux-gnu-gcc -march=native -O2 -pipe -march=native -O2 -pipe -fno-strict-aliasing -fPIC compile options: '-Inumpy/core/src/private -Inumpy/core/src -Inumpy/core -Inumpy/core/src/npymath -Inumpy/core/src/multiarray -Inumpy/core/src/umath -Inumpy/core/src/npys$ x86_64-pc-linux-gnu-gcc: _configtest.c _configtest.c:1:5: warning: conflicting types for built-in function ‘exp’ [-Wbuiltin-declaration-mismatch] int exp (void); ^~~ x86_64-pc-linux-gnu-gcc -march=native -O2 -pipe _configtest.o -lm -o _configtest success! ################## This is numpy trying to figure out if you need to add "-lm" for mathematical functions or not.
