It took a little time getting used to debugging under Inline::C.... However, you do have to take note that line numbers in error messages won't correspond with those in your Perl source code. Instead, they refer to a C source file that gets placed in the build directory, with an .xs suffix. Again, the error log and screen messages point to that same file.
This may or may not suit your preferences, but I always start my Inline::C files with:
This has several effects I find extremely useful.
But the main advantage of using this sequence of exactly 4 lines, is it means that the line numbers produced by the C compiler in its error messages logged to the screen, match exactly with those within the original I::C perl source file. Which means that most of the time there is no need to load the .c/.XS files in order to track down where the errors are, and so avoids another source of the "I edited the (wrong) file and nothing changed" gotcha.
And that is priceless.
