[!] Compilation error

fib.js: https://github.com/drujensen/fib

[mavavilj]

Not specific to fib.js. Error produced also with, e.g.:

hello.js

// hello world

NOTE:

Possibly the first report of this error, since other Issues seem to be using nectar as opposed to nerd.

[mavavilj]

Fixable by adding the type std::string to:

https://github.com/NerdLang/nerd/blob/400b367708c2fee58060f85fb8546a522c8add9c/self/compiler/native/squel/std.cpp#L77

Then the compiler finishes.

Also,

node nerd --run hello.ng

Hello World !

[adrien-thierry]

could you try with GCC10 or 9 just to check if it comes from GCC ?

[mavavilj]

could you try with GCC10 or 9 just to check if it comes from GCC ?

The __NERD_DIRNAME problem persists, but is fixable as I wrote earlier.

I am not an expert on GCC, but to me the programming error at L75 and L77 at https://github.com/NerdLang/nerd/blob/400b367708c2fee58060f85fb8546a522c8add9c/self/compiler/native/squel/std.cpp#L75 looks evident, since L73 is never executed and thus the variable is never initialized.
