I'm not familiar with icpc. What compiler is that? Where can I get a version to try?

[sanchit-misra]

It is Intel C++ compiler. I am not able to compile with g++ either.
$ make
g++ -z noexecstack -z relo -z now -c -o obj/abort_handler_s.o safeclib/abort_handler_s.c -Iinclude -fstack-protector-strong -fPIE -fPIC -O2 -D_FORTIFY_SOURCE=2 -Wformat -Wformat-security

Hmmm. This could be a C++ name mangling thing. Or more likely an environment thing.

The abort_handler_s.c is supposed to call the stdlib function abort(). This is defined in the safeclib_private.h file where slabort() is #defined to abort()
It seems that the include library settings are not correct for the environment you are using. Normally we find the function abort() under stdlib.h which is set up in the safeclib_private.h

Please verify that you are building with the appropriate setting for your environment, which would be to use HAVE_STDLIB_H for C++. See line 62 & 63 in the safeclib_private.h file.

"Please verify that you are building with the appropriate setting for your environment, which would be to use HAVE_STDLIB_H for C++. See line 62 & 63 in the safeclib_private.h file."
That fixed it but then I ran into a bunch of type casting errors.
I wanted to compile with icpc/g++ so as to be able to use this library in my C++ code. I was not able to use the library compiled by a C compiler due to C++ name mangling. But now I am just using extern "C". So, I don't need to compile with C++ compiler anymore.
