A way to debug the C functions of a Critcl script foo.tcl:
1- Insert these lines in the script foo.tcl
critcl::config force 1 ;# optional, force recompilation critcl::config keepsrc 1 ;# keep sources critcl::cheaders -g ;# keep symbols inside library
2- Launch the debugger gdb (or ddd)
shell$ ddd tclkit
3- Run the program in order to compile
gdb> run path_to_critcl/critcl foo.tcl
4- Insert breakpoint. Note that "critcl::cproc bar ..." generates C functions tcl_bar and c_bar
gdb> break tcl_bar
5- Rerun the program
gdb> run
PROBLEM : [Critcl] inserts directives {#line 1 "foo.tcl/bar"} and gdb is in trouble,
saying "No source file named bar".
The C source filename should be "~/.critcl/.../v033_....c" instead of "bar".''Temporary Solution: hack critcl''
1- Unwrap critcl
shell$ cd path_to_critcl shell$ sdx unwrap critcl
2- Modify the source "critcl.vfs/lib/critcl/critcl.vfs", commenting the directives
"#line 1 ..."
as
"/* #line 1 ...*/"
3- Wrap critcl
shell$ sdx wrap critcl
