Currently, python uses host gcc instead of cross-compile gcc in the last step of compiling build_ext(remove '--quiet' to show verbose): cross-gcc ... cross-gcc ... creating ~/out/python_ext_build/lib gcc -pthread -shared -Wl,-z ... This is wrong but may not cause any errors unless the features detected by cross-compiler do not match those for host compiler, and causes the following errors: /usr/lib64/gcc/bin/ld: cannot find -lunwind-x86 collect2: error: ld returned 1 exit status error: command 'gcc' failed with exit status 1 cp: cannot stat ‘~/out/python_ext_build/lib/perf.so’: No such file or directory Makefile.perf:257: recipe for target '~/out/python/perf.so' failed make[1]: *** [~/out/python/perf.so] Error 1 Makefile:68: recipe for target 'all' failed make: *** [all] Error 2 This issue is also reported and anwsered on stackoverflow.
