Build issue on RHEL 8.6

[sudha-zetta]

Hi,

I am trying to build this library on RHEL 8.6, using the master branch as of today.

./build-aux/autogen.sh
./configure

I ran make and make install, they ran without errors. But when I link against libsafec, I see these 2 errors which I am investigating.

libest/libest-source/src/est/.libs/libest.so: undefined reference to memzero_s' libest/libest-source/src/est/.libs/libest.so: undefined reference to memcpy_s'
collect2: error: ld returned 1 exit status

When I check the config.log, I see this error

configure:19287: result: no
configure:19287: checking for memzero_s
configure:19287: gcc -o conftest -O2 -D_FORTIFY_SOURCE=2 conftest.c >&5
/tmp/ccI0LrQJ.o: In function main': conftest.c:(.text.startup+0x7): undefined reference to memzero_s'
collect2: error: ld returned 1 exit status
configure:19287: $? = 1
configure: failed program was:

collect2: error: ld returned 1 exit status

I see a bunch of the functions that are undefined as well.

conftest.c:(.text.startup+0x7): undefined reference to `vsnprintf_s'
etc

Did configure work as expected? or Do I have to pass any arguments to it?

Thanks,

Here is nm results

[root@rhat862dev lib]# nm /usr/local/lib/libsafec.so | grep memzero_s
00000000000184c0 T _memzero_s_chk
[root@rhat862dev lib]# nm /usr/local/lib/libsafec.so | grep memcpy_s

Looks like the order of libs matters. Ensure -lsafec is after your -lest.
And that you link to -lsafec in your configure options. like adding it to LDFLAGS. Otherwise it won't be found automatically, because -lsafec is not in the compiler specs.
