compilation problem about cowl HOT 4 CLOSED

Looks like an error in the generated lexer. Which versions of Flex and Bison are you using? I may try to reproduce this, and either find a fix or bump the minimum required version of either tool.

FYI, it seems to build fine with the latest versions of Flex and Bison (2.6.4 and 3.5.1, respectively).

Thanks. cmake says the following:

-- Found BISON: /usr/bin/bison (found suitable version "3.0.4", minimum required is "3.0")
-- Found FLEX: /usr/bin/flex (found suitable version "2.6.1", minimum required is "2.6")
-- Desktop build selected
-- Found Doxygen: /usr/bin/doxygen (found version "1.8.13") found components: doxygen missing components: dot
-- Failed to find sphinx-build (missing: SPHINX_EXECUTABLE)

Alright so the culprit seems to be Flex: I tried downgrading to version 2.6.1 and it indeed causes compilation errors. Bison 3.0.4 is fine, so the 3.0+ requirement is ok. Mind trying to upgrade Flex to 2.6.4?

Let me know if that works, in which case I'll bump the minimum required version of the tool.

Fixed in 0420325.

Feel free to comment if upgrading Flex does not solve your issue.
