table-string | A fast string concatenator | Runtime Evironment library

It appears that the c4gl script is setting the GCC command option -fwritable-strings but your C compiler (apparently cc, but it could be a link to GCC) doesn't recognize it.

Depending on whether you have GCC or not, there are different ways to fix it. GCC 5.x (confirmed with GCC 5.3.0) and later does not support the option. Linux has been stuck on GCC 4.x for a long time, but is finally moving forward to later versions of GCC. So, if you've using GCC 5.x or later (use cc --version or gcc --version to find out which version you're using), you will need to edit the c4gl script (after making a backup copy of it) to remove the option.

However, there's also a chance that it was crucial and the code in the I4GL library does end up trying to modify string literals sometimes, and that will cause the program to crash. At that point, you're stuck with trying to report a problem to IBM Informix (HCL) technical support, assuming you have support, or with downgrading to a version 4.x GCC compiler.

Alright, I found the issue. The code generator creates the Xcode project as an XML file. If I open it in Xcode and apply a change to it, Xcode automatically converts the file to the other non-XML file format (i.e. as shown in the question)

Now, the code generator emits the following problematic code:

I have solved this problem by manually installing the same version of the missing packages as global.

In the third example you're doing an invalid conversion:

I answer with the code you updated in the comment.

Doesn't constexpr imply const?

It does, on the object being declared, in your case s. The result of applying constexpr is the object

As we mentioned to you in your helpdesk ticket on this same topic, our deploy environment is very naked - you have to:

1. specify dependencies that we can automatically install - npm/yarn deps, bower deps, gems and python packages.
2. install other dependencies yourself. the 'dotnet' program will be one of this type. We don't have it in our install environment, so you need to somehow import a copy of it into the environment. Seems like you can download the entire SDK here: https://www.microsoft.com/net/download/linux and then you need to import ONLY what is necessary for your build - it will take a very long time to build your site if we have to download the entire SDK, so see what you can trim down to get 'dotnet' to run.

For the purposes of #2, you'll probably need to test things in our build environment. How to do that, and details you'll need about the build environment such as OS type so you can download the right version of the SDK are described in this article:

This will take some work on your part. It will not be trivial. It is not something we can help with in more detail than that for free customers unless you come with specific questions and examples.

To address some thoughts in the comments:

• build.sh is indeed our build script
• 9:46:52 AM: /opt/build/build.sh: line 427: dotnet: command not found means that literally there is no dotnet command available to run - not that some config file is missing.
• we only try to run it once since you have set your command to use && to chain several commands - one fails, the whole chain fails, and we don't need to run it two more times once the first failure occurs :)

The problem is after the end condition of the do* loop. When variable i reaches the end of the string, the do* loop is exited but there is still a current-word which has not been added yet to words. When the end condition is met you need to add x to current-word and then current-word to words, before exiting the loop:

You need to also declare __console_log as extern "C". That clue is in that fact that function signature is included in the error message. lld is demanding the C++ symbol here (perhaps it would be more clear if it didn't, I'm not sure).
