Hi, it seems there is a bug in some header file in gnutls 3.5.17 . Platform: Ubuntu 17.10 up-to-date on x86_64 Target: orange-pi-zero + systemd Please read below an excerpt of the output: [...] checking dynamic linker characteristics... GNU/Linux ld.so checking how to hardcode library paths into programs... immediate checking whether stripping libraries is possible... yes checking if libtool supports shared libraries... yes checking whether to build shared libraries... yes checking whether to build static libraries... no checking how to run the C++ preprocessor... cpp configure: error: in `/home/santo/buildroot-2018.02/output/build/gnutls-3.5.17': configure: error: C++ preprocessor "cpp" fails sanity check See `config.log' for more details package/pkg-generic.mk:237: recipe for target '/home/santo/buildroot-2018.02/output/build/gnutls-3.5.17/.stamp_configured' failed make[1]: *** [/home/santo/buildroot-2018.02/output/build/gnutls-3.5.17/.stamp_configured] Error 1 Makefile:79: recipe for target '_all' failed make: *** [_all] Error 2 santo@lapin:~/buildroot-2018.02$ [...] in the corresponding config.log: [...] ldroot-2018.02/output/host/arm-buildroot-linux-gnueabihf/bin --enable-shared --disable-libgomp Thread model: posix gcc version 6.4.0 (Buildroot 2018.02) configure:5369: $? = 0 configure:5358: /home/santo/buildroot-2018.02/output/host/bin/arm-buildroot-linux-gnueabihf-gcc -V >&5 arm-buildroot-linux-gnueabihf-gcc.br_real: error: unrecognized command line option '-V' arm-buildroot-linux-gnueabihf-gcc.br_real: fatal error: no input files compilation terminated. configure:5369: $? = 1 configure:5358: /home/santo/buildroot-2018.02/output/host/bin/arm-buildroot-linux-gnueabihf-gcc -qversion >&5 [...] Please let me know if teh above is not enough. Thank you
The cited config.log fragment is unrelated to the shown error (1), please try: $ make clean $ make And if the error shows up again please provide your .config/defconfig file (see http://nightly.buildroot.org/manual.html#reporting-bugs) and/or the complete build/gnutls-3.5.17/config.log file... (1) not all errors in config.log lead to an configure error, there are many/hundreds of tests in there...

Hi Peter, thank you for looking into this. I tried to install buildroot on another machine, but the error is the same. Perhaps a better spot can be: [...] configure:49488: result: cpp configure:49508: cpp -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -I/storage/santo/buildroot/buildroot-2018.02/output/host/arm-buildroot-linux-gnueabihf/sysroot/usr/include conftest.cpp In file included from /storage/santo/buildroot/buildroot-2018.02/output/host/arm-buildroot-linux-gnueabihf/sysroot/usr/include/features.h:447:0, from /storage/santo/buildroot/buildroot-2018.02/output/host/arm-buildroot-linux-gnueabihf/sysroot/usr/include/bits/libc-header-start.h:33, from /storage/santo/buildroot/buildroot-2018.02/output/host/arm-buildroot-linux-gnueabihf/sysroot/usr/include/limits.h:26, from conftest.cpp:683: /storage/santo/buildroot/buildroot-2018.02/output/host/arm-buildroot-linux-gnueabihf/sysroot/usr/include/gnu/stubs.h:7:11: fatal error: gnu/stubs-soft.h: No such file or directory # include <gnu/stubs-soft.h> ^~~~~~~~~~~~~~~~~~ compilation terminated. configure:49508: $? = 1 configure: failed program was: | /* confdefs.h */ | #define PACKAGE_NAME "GnuTLS" | #define PACKAGE_TARNAME "gnutls" [...] . Anyway I've attached the buildroot .config, the linux kernel .config and the config.log. Thank you,
Yes, this config.log location was the real failure reason. The hints to the solution are: - checking how to run the C++ preprocessor... cpp - configure:49488: result: cpp Your toolchain is missing C++ support (and the gnutls packages is missing the C++ dependency), the following buildroot config change fixed the failure for me: $ diff -u .config.old .config @@ -299,7 +300,7 @@ BR2_GCC_SUPPORTS_FINEGRAINEDMTUNE=y BR2_GCC_VERSION="6.4.0" BR2_EXTRA_GCC_CONFIG_OPTIONS="" -# BR2_TOOLCHAIN_BUILDROOT_CXX is not set +BR2_TOOLCHAIN_BUILDROOT_CXX=y # BR2_TOOLCHAIN_BUILDROOT_FORTRAN is not set # BR2_GCC_ENABLE_LTO is not set # BR2_GCC_ENABLE_OPENMP is not set Regards, Peter
Hi Peter, thank you very much, your solution works and I've been able to generate the image. Thank you very much again for your time. Best,
