Have you looked in config.log? configure:3651: checking for gcc configure:3667: found /usr/bin/gcc configure:3678: result: gcc Or the less verbose form that you see on the console while it's actually running? checking for gcc... gcc checking whether the C compiler works... yes checking for C compiler default output file name... a.out checking for suffix of executables... checking whether we are cross compiling... no checking for suffix of object files... o checking whether we are using the GNU C compiler... yes checking whether gcc accepts -g... yes checking for gcc option to accept ISO C89... none needed checking how to run the C preprocessor... gcc -E And of course, there's all the headers that Python looks for: checking spawn.h usability... yes checking spawn.h presence... yes checking for spawn.h... yes checking util.h usability... no checking util.h presence... no checking for util.h... no checking alloca.h usability... yes checking alloca.h presence... yes checking for alloca.h... yes checking endian.h usability... yes checking endian.h presence... yes checking for endian.h... yes and the standard library functions: checking for kill... yes checking for killpg... yes checking for lchmod... no checking for lchown... yes checking for linkat... yes checking for lstat... yes checking for lutimes... yes checking for mmap... yes and some architecture-specific things: checking whether C doubles are little-endian IEEE 754 binary64... yes checking whether C doubles are big-endian IEEE 754 binary64... no checking whether C doubles are ARM mixed-endian IEEE 754 binary64... no checking whether we can use gcc inline assembler to get and set x87 control word... yes checking whether we can use gcc inline assembler to get and set mc68881 fpcr... no checking for x87-style double rounding... no For "highly classified" information, this is being very well hidden in plain sight.
