Does anyone have experience in compiling C code in 4GL? I'm currently in charge in the C module of a 4GL program, but I couldn't know how could I debug the C code. I have try put a file I/O to put my debugging information into that log. Anyhow the C program doesn't output any files. Could you share some light here as long as I can debug my C code.

THanks @!

You have to compile it using the -g option of the c compiler.
have a look in the c4gl script either hard code it there or set the appropiate env var.

Then you can debug your program using gdb, dbx the usual way.

I wasn't using cfgl, I'm using fglgo.

Hello Lok Kok Hoe,

Ah r4gl instead of i4gl so you are using a custom runner???

That is a bit long ago, you have to gointo the manuals and see where the
custom runner is build. there you have to add the -g flag.

Debug would be something like

gdb yourcustomrunner

break <whereever you want it >

run <your4glprogram>

This is not tested and i can not verify it since i do not have access to 4gl
anymore..... hope it helps bit.
