Generic Autotools Advice: 1) modern autotools (last 10 years or more) support setting variables like (CXX) on the command line, after any arguments. This is superior to using the environment because the settings get stored in the logs, which makes for easier debugging. Something like: ../goodie-source/configure —prefix=/opt/goodies CC=“g++ -m64” CFLAGS=“-Wall”
2) Build outside the source tree. Unless the build is broken this will work and keep you from mixing build products with sources. If you want to do that, and pastebin config.log & config.status I’d be happy to look. Another thing you can try is to define the compilers as: CXX=“g++ -march=pentium4 -mtune=i686” (but of course with your ARMish values instead) This will keep things consistent if the CXXFLAGS aren’t added in all the places where they’re needed.
