Each library passed to fidlc must have a unique name:
{% include “docs/reference/fidl/language/error-catalog/label/_bad.md” %}
{% includecode gerrit_repo="fuchsia/fuchsia" gerrit_path="tools/fidl/fidlc/tests/fidl/bad/fi-0041-a.test.fidl" exclude_regexp="\/\/ (Copyright 20|Use of|found in).*" %}
{% includecode gerrit_repo="fuchsia/fuchsia" gerrit_path="tools/fidl/fidlc/tests/fidl/bad/fi-0041-b.test.fidl" exclude_regexp="\/\/ (Copyright 20|Use of|found in).*" %}
Ensure that all libraries have unique names:
{% include “docs/reference/fidl/language/error-catalog/label/_good.md” %}
{% includecode gerrit_repo="fuchsia/fuchsia" gerrit_path="tools/fidl/fidlc/tests/fidl/good/fi-0041-a.test.fidl" exclude_regexp="\/\/ (Copyright 20|Use of|found in).*" %}
{% includecode gerrit_repo="fuchsia/fuchsia" gerrit_path="tools/fidl/fidlc/tests/fidl/good/fi-0041-b.test.fidl" exclude_regexp="\/\/ (Copyright 20|Use of|found in).*" %}
This error is often caused by arguments being supplied to fidlc in an incorrect manner. The constituent files that make up each library necessary for compilation (that is, the library being compiled and all of its transitive dependencies) must be supplied as a single space-separated list of files passed via the --files argument, with one such flag per library. A common mistake is to try to pass the file for all libraries in a single --files list.
