Has something changed recently on how product-component structure is supposed to be used? I have three files:

1. prd.tex

\environment env

\startproduct prd

\component cmp

\stopproduct

2. env.tex

\startenvironment env

\define\testing{This is a test}

\stopenvironment

3. cmp.tex

\product prd

\startcomponent cmp

Testing \testing

\stopcomponent

When I compile cmp.tex, I get:

%--------------------------%<----------------------------- […] mtx-context | fatal error: return code: 1% %--------------------------%<-----------------------------

Shouldn't the product file not load the component file (or anything else inside \startproduct .. \stopproduct) when compiling a component?

The product file loads the component but this isn’t what you’re doing.

You process the component which doesn’t load product file because this would end in a loop because the product would then again load the component etc.

Add “\environment env” at the begin of your component file and the problem disappears. Since environment files are loaded only once it doesn’t matter when the line is in each component file.

I thought that the whole point of adding `\product ...` in a component file was so that I do not have to add all the `\environment ...` in the component file. Actually, if I change the product -> component then everything works as expected, so perhaps I did not remember correctly how the project-product-component hierarchy is to be used. I thought that the project part was optional, but it seems that one must include a project as well (if you want not to add all the environments in the component file) Aditya
