I delete -Wmaybe-uninitialized and -Wunused-result from wolfssl-3.13.0-stable/Makefile +1559, and have benn passed.

Hi Cloudyfly,

It looks like the x86_64-suse-linux doesn't understand the CFLAGS for -Wmaybe-uninitialized -Wunused-result. I'll see about adding an exclusion for those flags on that platform in our build scripts.

Thanks, David Garske, wolfSSL

Hi Cloudyfly,

If you run the ./configure script it runs a check to see if -Wunused-result and -Wmaybe-uninitialized are supported.

configure:28604: checking whether C compiler accepts -Wunused-result
configure:27470: checking whether C compiler accepts -Wmaybe-uninitialized

Did you run ./configure before calling make?

[cloudyfly]

suse can't recognize these flags.
for example,
SZX1000381038:~ # gcc a.c
SZX1000381038:~ # gcc a.c -Wmaybe-uninitialized
cc1: error: unrecognized command line option "-Wmaybe-uninitialized"

@cloudyfly,

I have tested your configuration:

./configure --prefix=/usr --infodir=/usr/share/info --mandir=/usr/share/man --libdir=/usr/lib64 --libexecdir=/usr/lib64 --enable-languages=c,c++,objc,fortran,obj-c++,java,ada --enable-checking=release --with-gxx-include-dir=/usr/include/c++/4.3 --enable-ssp --disable-libssp --with-bugurl=http://bugs.opensuse.org/ --with-pkgversion='SUSE Linux' --disable-libgcj --disable-libmudflap --with-slibdir=/lib64 --with-system-zlib --enable-__cxa_atexit --enable-libstdcxx-allocator=new --disable-libstdcxx-pch --enable-version-specific-runtime-libs --program-suffix=-4.3 --enable-linux-futex --without-system-libunwind --with-cpu=generic --build=x86_64-suse-linux

Using this gcc:

gcc -v

Thank you for bringing this to our attention but we are unable to reproduce this report. Could you make sure you have all the correct dependencies installed for using autoconf and auto build IE:

linux-headers-generic
build-essential
libtool

We have tried to reproduce with both our master branch and our 3.14.0 release. There is no issue on SUSE Linux x86_64 that we can reproduce.

The one thing I did notice was you had ../configure are you attempting a shadow build from a sub-directory like you would if using cmake?

If so that functionality is not supported at this time.

Warm Regards,

Kaleb
