QUESTION
I am automating the building and unit testing of a personal project using bash scripts (parts of the unit testing have been reviewed on Code Review), cmake and make on the latest version of Fedora Linux. The postive test passes on on the build system, however, when I force an LD failure in one of the unit tests the build still passes at the higher levels. It needs to fail at all levels.
Here is the error message from the make generated by a cmake command:

QUESTION
I have a c program I'm writing that I want to be portable and future compliant. The POSIX function strdup()
is not in the current C standard, but it has been added to the C2x standard. Will this code work properly with C standard compliant compilers in the future.
Will it work on both POSIX and non POSIX systems?

Answered 2020-Sep-03 at 23:32Read carefully the C11 standard n1570. For things like Arduino, you might not even have any malloc
, and you could have some free-standing implemention of C11.
As a concrete example, the Linux kernel is coded in C, and your code could not be part of it.
Also see this answer providing some funny implementation of malloc
(you could extend it to calloc
...)
Of course not in general.Will this code work properly with C standard compliant compilers in the future.
Look on many examples of toy operating systems on OSDEV.
You could have some operating system without malloc
or calloc
but with a C compiler.
I have a c program I'm writing that I want to be portable and future compliant.
The motto I read somewhere is: there is no such thing as portable programs, just programs which have been ported (to some given systems)
Did you consider some approach inspired by GNU autoconf ? Your build automation could use preprocessing tricks and/or generate C code with e.g. GPP, SWIG or other tools.

Install lexical-analyzer
You can use lexical-analyzer like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
