You are missing a cross C++ compiler. Since it is only needed for the testsuite this isn't a fatal error. (In reply to Andreas Schwab from comment #1) > You are missing a cross C++ compiler.

Sorry but I think that I do have a C++ compiler. it is available in the gcc prefix directory: /root/andro_test/gcc-build/gcc/cpp Regards, Ataro.

Your config.log shows it's not found: configure:2920: checking for arm-linux-gnueabi-g++ configure:2950: result: no And the configure falls back to trying the system G++: configure:2964: checking for g++ configure:2980: found /usr/bin/g++ configure:2991: result: g++ And the system g++ won't work because you're building cross.

I think I've added it to the $PATH but somehow the configure script failed to detect it. I also saw that it failed to find the nm cross compiled tool from binutils and I've to add it manually to the config.make file. However, I've started a clean build of binutils, gcc and glibc all with the same --prefix directory and everything went all. (everything except that I was must to add the -O2 and the -I/root/androd_test/linux-3.4.57 flags to the $CFLAGS and $CPPFLAGS environment variables). Thanks you for your replies. Regards, Ataro. |
Created attachment 9753 [details] configure command and config.log output. Hello, When trying to compile glibc for arm using the attached configure command, it fails to compile because it try to pass the flag '--32' to the cross assembler which is not applicable to the cross assembler. Regards, Ataro.
